PFC CONSULTING LIMITED 133RFP for Selection of Bidder as Transmission Service Provider ANNEXURE - E SPECIFIC TECHNICAL REQUIREMENTS FOR SYNCHRONOUS CONDENSER

1. INTRODUCTION This technical specification for Synchronous Condenser Stations consists of Synchronous Condenser (SynCon) units alternatively referred to as Synchronous Compensator where a SynCon unit consists of one synchronous condenser along with associated step-up transformer

The station shall operate in the leading and lagging MVAr region, as required to meet the specified inertia, short circuit requirements and reactive power capability curve and dynamic performance criteria.

The SynCon primarily shall be designed for continuous operation under varying grid conditions.

The SynCon shall be equipped with a digital AVR (Automatic Voltage Regulator), Under/Over Excitation Limiters (UEL/OEL), V/Hz protection, and high inertia flywheels (if applicable) to enhance transient stability and damping.

The SynCon Station may consist of multiple identical synchronous condenser units, each operating in parallel and connected to the 400 kV HV bus (PCC), as per the design and space available. The design shall ensure compliance with grid code requirements, and the provision of inertia and fault current to support reliable and stable system operation.

1.1 Definitions For the purpose of this specification, the following definitions / abbreviations are used:

PCC (Point of Common Coupling): Point of Common Coupling (herein also called as Point of Interconnection (POI) is the connection point between the Synchronous Condenser (SynCon) Station/plant (HV Side of step-up transformer) and ISTS at which performance requirements are defined.

Reference Voltage (Vref): The voltage set-point at the PCC where SynCon is expected to regulate voltage by injecting or absorbing reactive power while maintaining system stability.

MV (Medium Voltage): The voltage level at the low-voltage side of the step-up transformer, where SynCon and associated equipment are connected.

SynCon (Synchronous Condenser): SynCon is a DC-excited Synchronous machine that runs at no load and is used to control reactive power, which improves voltage stability and power factor in electrical grids In the entire document the notion synchronous condenser refers to the synchronous machine installed in the Synchronous Condenser unit. The synchronous condenser shall be connected to the step-up transformer via the generator circuit breaker by an Isolated Phase Bus duct.

Following convention is used in this specification to define the reactive power output of the

Synchronous condenser unit: a) The notion capacitive reactive power (indicated as “+ MVAr”) is used when the Synchronous condenser unit is injecting reactive power to the grid, i.e. when the synchronous condenser is operating in the overexcited capability range.

PFC CONSULTING LIMITED 134RFP for Selection of Bidder as Transmission Service Provider b) The notion inductive reactive power (indicated as “- MVAr”) is used when the Synchronous condenser unit is absorbing reactive power from the grid, i.e. when the synchronous condenser is operating in the under excited capability range.

SynCon Unit (Synchronous Condenser Unit): In the entire document Synchronous condenser unit refers to the full scope of equipment working as one system at PCC. It includes but is not

limited to:

(i) Synchronous Condenser and its auxiliaries.

(ii) Excitation System (Static/Brushless)

(iii) Flywheel and its auxiliaries, if option chosen

(iv) Step-up Transformers

(v) Generator Circuit Breaker (GCB)

(vi) Unit Transformer (Auxiliary Transformers)

(vii) Isolated Phase Bus Duct (IPBD) connecting Generator and Step-up Transformer

(viii) Lube Oil System

(ix) Auxiliary Power Supply (medium voltage/ low voltage)

(x) Equipment for control and protection of the equipment supplied under the specifications.

(xi) Reactive Power Oscillation Damper (RPOD)

(xiv) SynCon starting system (SFC/Pony motor) AVR (Automatic Voltage Regulator): A digital control system associated with each SynCon Unit responsible for regulating the field excitation to maintain the terminal voltage or reactive power output, always fully redundant, this is channel A and B in terms of control and power circuits, with hot standby and automatic switch functionalities. AVR shall include functionalities

like:

(a) UEL (Under Excitation Limiter): A protective function or control logic that prevents the SynCon from operating in unstable or under-excited regions of the capability curve, avoiding excessive reactive power absorption.

(b) OEL / OVEL (Over Excitation Limiter): A protection system that limits the field current to prevent thermal damage to the field winding during overexcited operation (i.e., high reactive power generation).

Flywheel: A rotating mechanical mass connected to the SynCon shaft to increase its inertia and provide additional damping and system strength benefits.

Step-up Transformer: A Transformer connecting the SynCon (MV side) to the ISTS (400 kV side i.e. PCC), designed to match voltage levels and system impedance characteristics.

Capability Curve: The operational envelope of the SynCon showing the permissible limits of reactive power generation or absorption with respect to voltage at PCC and stator current.

Lagging Operation: Operation in which the SynCon absorbs capacitive reactive power (under- excited operation).

Leading Operation: Operation in which the SynCon generates capacitive reactive power (over- excited operation).

Response Time: The duration from a step change in control signal until the voltage changes by 90% of its final change, before any overshoot.

PFC CONSULTING LIMITED 135RFP for Selection of Bidder as Transmission Service Provider

Settling Time: The duration from a step change in control signal input until the SynCon output settles to within +5% of required control output.

Overshoot: The maximum system output minus the final settled value, divided by the actual change in system output (i.e., from its initial value to the final settled value), when the final settled value is within the defined settling band, expressed as a percentage.

Excitation response ratio: It is called the excitation system nominal response and defined as the rate of increase of the excitation system output voltage determined from the excitation system voltage response curve, divided by the rated field voltage. This rate, if maintained constant (curve ac), would develop the same voltage-time area as obtained from the response (curve ab) over the first half-second interval (unless a different time interval is specified). The RR is a measure of the speed of response for the excitation system, the higher the RR, the faster the response Response ratio Reactive power oscillation damper (RPOD): A reactive power oscillation damper (RPOD) implemented through control strategy designed to damp low-frequency electromechanical oscillations (typically 0.2–2 Hz) in power systems by modulating the SynCon reactive power output (Q) in response to system oscillations. When equipped with an excitation control system and a power oscillation damping (POD) controller, it can also actively damp oscillations in the grid by modulating its reactive power.

20. Availability and Reliability

20.1 Availability

The percentage availability of Synchronous Condenser is defined as follows: 𝑇𝑜𝑡𝑎𝑙 𝑡𝑖𝑚𝑒 𝑆𝑦𝑛𝐶𝑜𝑛 𝑖𝑠 𝑎𝑏𝑙𝑒 𝑡𝑜 𝑃𝑒𝑟𝑓𝑟𝑜𝑚 𝑠𝑝𝑒𝑐𝑖𝑓𝑖𝑒𝑑 𝐷𝑢𝑡𝑦 % 𝐴𝑣𝑎𝑖𝑙𝑎𝑏𝑖𝑙𝑖𝑡𝑦 = 𝑥 100 𝑇𝑜𝑡𝑎𝑙 𝑡𝑖𝑚𝑒 𝑃𝑒𝑟𝑖𝑜𝑑 Synchronous Condenser shall be considered to be available for service only if it is able to perform the whole of the specified duty. Operation with limited control functions or within a limited range of outputs (any parameters i.e. Inertia, Short Circuit MVA and Capacitive and Inductive MVAr) due to a subsystem failure shall be treated as unscheduled servicing downtime. The period basis for availability calculation shall be 12 months (365 days).

The total time period during which the SynCon Station is not able to perform the specified duty shall include Planned Outage hours (POH), Maintenance Outage Hours (MOH) and Forced Outage Hours (FOH).

Planned Outage (POH = Planned Outage Hours) is the state where the Equipment is unavailable due to Planned Maintenance activities (Scheduled Routine Maintenance, Scheduled Annual and Biennial Maintenance, Small Revisions and Major Revisions) that require the shutdown of the Equipment. Such activities leading to a Planned Outage.

Unplanned Outage Unplanned Outage is the state where the Equipment is unavailable but is not in the Planned Outage state.

The Unplanned Outage can be due to Forced Outage Hours (FOH = Forced Outage Hours) or due to Maintenance Outage Hours (MOH = Maintenance Outage Hours) Forced Outage is considered as an outage that requires removal of the Equipment from the Available State immediately or within 7 days maximum.

Maintenance Outage is considered an outage that does not require immediate removal from the Available State but requires the Equipment to be removed from the Available State before the next Planned Outage. This is scheduled at least 7 days in advance (otherwise it’s classified as FOH).

20.2 Reliability In the assessment of reliability, the following events shall also be considered to constitute a

SynCon Station outage:

PFC CONSULTING LIMITED 174RFP for Selection of Bidder as Transmission Service Provider i) A SynCon Station shut down. ii) A reduction of SynCon Station capacity (any parameters i.e. Inertia, Short Circuit MVA and Capacitive and Inductive MVAr) due to an outage of any component of SynCon Station The calculated reliability of the complete SynCon Station shall be equal to or exceed the following design target values.

Design target for SynCon Max acceptable Guaranteed Station value for SynCon Station Total Number of Forced 3 5 Outages Here definition of Forced Outage shall be considered as same as given in the “20.1 Availability”.

SPV (UNDER INCOPORATION) 87 ___, 2026Transmission Service Agreement Annexure - B SPECIFIC TECHNICAL REQUIREMENTS FOR SYNCHRONOUS CONDENSER

1. INTRODUCTION This technical specification for Synchronous Condenser Stations consists of Synchronous Condenser (SynCon) units alternatively referred to as Synchronous Compensator where a SynCon unit consists of one synchronous condenser along with associated step-up transformer (s), cooling systems, flywheels (if applicable), auxiliary system and all associated switchgears.

Synchronous Condenser shall provide Inertia, Short Circuit support, continuous and dynamic supply of reactive power (capacitive and inductive) support for the regulation and stabilization of the voltage of 400 kV at Point of Common Coupling (PCC) under normal and transient conditions. The station shall operate in the leading and lagging MVAr region, as required to meet the specified inertia, short circuit requirements and reactive power capability curve and dynamic performance criteria.

The SynCon primarily shall be designed for continuous operation under varying grid conditions. The SynCon shall be equipped with a digital AVR (Automatic Voltage Regulator), Under/Over Excitation Limiters (UEL/OEL), V/Hz protection, and high inertia flywheels (if applicable) to enhance transient stability and damping.

The SynCon Station may consist of multiple identical synchronous condenser units, each operating in parallel and connected to the 400 kV HV bus (PCC), as per the design and space available. The design shall ensure compliance with grid code requirements, and the provision of inertia and fault current to support reliable and stable system operation.

1.1 Definitions For the purpose of this specification, the following definitions / abbreviations are used:

PCC (Point of Common Coupling): Point of Common Coupling (herein also called as Point of Interconnection (POI) is the connection point between the Synchronous Condenser

(SynCon) Station/plant (HV Side of step-up transformer) and ISTS at which performance requirements are defined.

Reference Voltage (Vref): The voltage set-point at the PCC where SynCon is expected to regulate voltage by injecting or absorbing reactive power while maintaining system stability.

MV (Medium Voltage): The voltage level at the low-voltage side of the step-up transformer, where SynCon and associated equipment are connected.

SynCon (Synchronous Condenser): SynCon is a DC-excited Synchronous machine that runs at no load and is used to control reactive power, which improves voltage stability and power factor in electrical grids In the entire document the notion synchronous condenser refers to the synchronous machine installed in the Synchronous Condenser unit. The synchronous condenser shall be connected to the step-up transformer via the generator circuit breaker by an Isolated Phase Bus duct.

Following convention is used in this specification to define the reactive power output of

the Synchronous condenser unit:

SPV (UNDER INCOPORATION) 88 ___, 2026Transmission Service Agreement a) The notion capacitive reactive power (indicated as “+ MVAr”) is used when the Synchronous condenser unit is injecting reactive power to the grid, i.e. when the synchronous condenser is operating in the overexcited capability range.

b) The notion inductive reactive power (indicated as “- MVAr”) is used when the Synchronous condenser unit is absorbing reactive power from the grid, i.e. when the synchronous condenser is operating in the under excited capability range.

SynCon Unit (Synchronous Condenser Unit): In the entire document Synchronous condenser unit refers to the full scope of equipment working as one system at PCC. It

includes but is not limited to:

(i) Synchronous Condenser and its auxiliaries.

(ii) Excitation System (Static/Brushless)

(iii) Flywheel and its auxiliaries, if option chosen

(iv) Step-up Transformers

(v) Generator Circuit Breaker (GCB)

(vi) Unit Transformer (Auxiliary Transformers)

(vii) Isolated Phase Bus Duct (IPBD) connecting Generator and Step-up Transformer

(viii) Lube Oil System

(ix) Auxiliary Power Supply (medium voltage/ low voltage)

(x) Equipment for control and protection of the equipment supplied under the specifications.

(xi) Reactive Power Oscillation Damper (RPOD)

(xii) Cooling System

(xiii) Other auxiliary systems required for power operation of the Synchronous Condenser.

(xiv) SynCon starting system (SFC/Pony motor) AVR (Automatic Voltage Regulator): A digital control system associated with each SynCon Unit responsible for regulating the field excitation to maintain the terminal voltage or reactive power output, always fully redundant, this is channel A and B in terms of control and power circuits, with hot standby and automatic switch functionalities. AVR shall

include functionalities like:

(a) UEL (Under Excitation Limiter): A protective function or control logic that prevents the SynCon from operating in unstable or under-excited regions of the capability curve, avoiding excessive reactive power absorption.

(b) OEL / OVEL (Over Excitation Limiter): A protection system that limits the field current to prevent thermal damage to the field winding during overexcited operation (i.e., high reactive power generation).

Flywheel: A rotating mechanical mass connected to the SynCon shaft to increase its inertia and provide additional damping and system strength benefits.

Step-up Transformer: A Transformer connecting the SynCon (MV side) to the ISTS (400 kV side i.e. PCC), designed to match voltage levels and system impedance characteristics.

Capability Curve: The operational envelope of the SynCon showing the permissible limits of reactive power generation or absorption with respect to voltage at PCC and stator current.

Lagging Operation: Operation in which the SynCon absorbs capacitive reactive power (under-excited operation).

SPV (UNDER INCOPORATION) 89 ___, 2026Transmission Service Agreement

Leading Operation: Operation in which the SynCon generates capacitive reactive power (over-excited operation).

Response Time: The duration from a step change in control signal until the voltage changes by 90% of its final change, before any overshoot.

Settling Time: The duration from a step change in control signal input until the SynCon output settles to within +5% of required control output.

Overshoot: The maximum system output minus the final settled value, divided by the actual change in system output (i.e., from its initial value to the final settled value), when the final settled value is within the defined settling band, expressed as a percentage.

Excitation response ratio: It is called the excitation system nominal response and defined as the rate of increase of the excitation system output voltage determined from the excitation system voltage response curve, divided by the rated field voltage. This rate, if maintained constant (curve ac), would develop the same voltage-time area as obtained from the response (curve ab) over the first half-second interval (unless a different time interval is specified). The RR is a measure of the speed of response for the excitation system, the higher the RR, the faster the response Response ratio Reactive power oscillation damper (RPOD): A reactive power oscillation damper (RPOD) implemented through control strategy designed to damp low-frequency electromechanical oscillations (typically 0.2–2 Hz) in power systems by modulating the SynCon reactive power output (Q) in response to system oscillations. When equipped with an excitation control system and a power oscillation damping (POD) controller, it can also actively damp oscillations in the grid by modulating its reactive power.

Operation with limited control functions or within a limited range of outputs (any parameters i.e. Inertia, Short Circuit MVA and Capacitive and Inductive MVAr) due to a subsystem failure shall be treated as unscheduled servicing downtime. The period basis for availability calculation shall be 12 months (365 days).

The total time period during which the SynCon Station is not able to perform the specified duty shall include Planned Outage hours (POH), Maintenance Outage Hours (MOH) and Forced Outage Hours (FOH).

Planned Outage (POH = Planned Outage Hours) is the state where the Equipment is unavailable due to Planned Maintenance activities (Scheduled Routine Maintenance, Scheduled Annual and Biennial Maintenance, Small Revisions and Major Revisions) that require the shutdown of the Equipment. Such activities leading to a Planned Outage.

Unplanned Outage Unplanned Outage is the state where the Equipment is unavailable but is not in the Planned Outage state.

The Unplanned Outage can be due to Forced Outage Hours (FOH = Forced Outage Hours) or due to Maintenance Outage Hours (MOH = Maintenance Outage Hours) Forced Outage is considered as an outage that requires removal of the Equipment from the Available State immediately or within 7 days maximum.

Maintenance Outage is considered an outage that does not require immediate removal from the Available State but requires the Equipment to be removed from the Available State before the next Planned Outage. This is scheduled at least 7 days in advance (otherwise it’s classified as FOH).

20.2 Reliability In the assessment of reliability, the following events shall also be considered to constitute

a SynCon Station outage: i) A SynCon Station shut down. ii) A reduction of SynCon Station capacity (any parameters i.e. Inertia, Short Circuit MVA and Capacitive and Inductive MVAr) due to an outage of any component of SynCon Station The calculated reliability of the complete SynCon Station shall be equal to or exceed the following design target values.

Schedule: 6 Appendix –IV to Central Electricity Regulatory Commission (Terms and Conditions of Tariff) Regulations, 2024 Procedure for Calculation of Transmission System Availability Factor for a Month

1. Transmission system availability factor for nth calendar month (“TAFPn”) shall be calculated by the respective transmission licensee, verified by the concerned Regional Load Dispatch Centre (RLDC) and certified by the Member-Secretary, Regional Power Committee of the region concerned, separately for each AC and HVDC transmission system and grouped according to sharing of transmission charges. In the case of the AC system, transmission System Availability shall be calculated separately for each Regional Transmission System and inter-regional transmission system. In the case of the HVDC system, transmission System Availability shall be calculated on a consolidated basis for all inter-state HVDC systems.

2. Transmission system availability factor for nth calendar month (“TAFPn”) shall be

calculated by considering the following: i) AC transmission lines: Each circuit of AC transmission line shall be considered as one element; ii) Inter-Connecting Transformers (ICTs): Each ICT bank (three single- phase transformers together) shall form one element;

iii) Static VAR Compensator (SVC): SVC, along with SVC transformer, shall form one element; iv) Bus Reactors or Switchable line reactors: Each Bus Reactors or Switchable line reactors shall be considered as one element;

v) HVDC Bi-pole links: Each pole of the HVDC link, along with associated equipment at both ends, shall be considered as one element; vi) HVDC back-to-back station: Each block of the HVDC back-to-back station shall be considered as one element. If the associated AC line (necessary for the transfer of inter-regional power through the HVDC back-to-back station) is not available, the HVDC back-to-back station block shall also be considered unavailable;

vii) Static Synchronous Compensation (“STATCOM”): Each STATCOM shall be SPV UNDER INCORPORATION 152 |___, 2026Transmission Service Agreement considered as a separate element.

3. The Availability of the AC and HVDC portion of the Transmission system shall be calculated

by considering each category of transmission elements as under:

SPV UNDER INCORPORATION 153 |___, 2026Transmission Service Agreement

4. The availability for each category of transmission elements shall be calculated based on the weightage factor, total hours under consideration and non-available hours for each element of that category. The formulae for calculation of the Availability of each category of the transmission elements are as per Appendix-V. The weightage factor for each

category of transmission elements shall be considered as under:

(a) For each circuit of the AC line – The number of sub-conductors in the line multiplied by ckt-km;

(b) For each HVDC pole- The rated MW capacity x ckt-km;

(c) For each ICT bank – The rated MVA capacity;

(d) For SVC- The rated MVAr capacity (inductive and capacitive);

(e) For Bus Reactor/switchable line reactors – The rated MVAr capacity;

(f) For HVDC back-to-back stations connecting two Regional grids- Rated MW capacity of each block; and

(g) For STATCOM – Total rated MVAr Capacity.

5. The transmission elements under outage due to the following reasons shall be deemed

to be available: i. Shut down availed for maintenance of another transmission scheme or construction of new element or renovation/upgradation/additional capitalization in an existing system approved by the Commission. If the other transmission scheme belongs to the transmission licensee, the Member Secretary, RPC may restrict the deemed availability period to that considered reasonable by him for the work involved. In case of a dispute regarding deemed availability, the matter may be referred to the Chairperson, CEA, within 30 days.

ii. Switching off of a transmission line to restrict over-voltage and manual tripping of switched reactors as per the directions of the concerned RLDC. iii. Shut down of a transmission line due to the Project(s) of NHAI, Railways and Border Road Organization, including for shifting or modification of such transmission line or any other infrastructure project approved by Ministry of Power.
