CHAPTER 5 U.K. Compliance simulations for synchronous power-generating modules

Article 51 U.K. Compliance simulations for type B synchronous power-generating modules

1. Power-generating facility owners shall undertake LFSM-O response simulations in relation to type B synchronous power-generating modules. Instead of the relevant simulations, the power-generating facility owner may use equipment certificates issued by an authorised certifier to demonstrate compliance with the relevant requirement. In that case, the equipment certificates shall be provided to the relevant system operator.

2. With regard to the LFSM-O response simulation the following requirements shall apply:

(a) the power-generating module's capability to modulate active power at high frequency in accordance with Article 13(2) shall be demonstrated by simulation;

(b) the simulation shall be carried out by means of high frequency steps and ramps reaching minimum regulating level, taking into account the droop settings and the deadband;

(c) the simulation shall be deemed successful in the event that:

(i)

the simulation model of the power-generating module is validated against the compliance test for LFSM-O response described in Article 44(2); and

(ii)

compliance with the requirement set out in Article 13(2) is demonstrated.

3. With regard to the simulation of fault-ride-through capability of type B synchronous power-generating modules, the following requirements shall apply:

(a) the power-generating module's capability to ride through faults in accordance with the conditions set out in subparagraph (a) of Article 14(3) shall be demonstrated by simulation;

(b) the simulation shall be deemed successful if compliance with the requirement set out in point (a) of Article 14(3) is demonstrated.

4. With regard to the post fault active power recovery simulation the following requirements shall apply:

(a) the power-generating module's capability to provide post fault active power recovery referred to in the conditions set out in Article 17(3) shall be demonstrated;

(b) the simulation shall be deemed successful if compliance with the requirement set out in Article 17(3) is demonstrated.

Article 52 U.K. Compliance simulations for type C synchronous power-generating modules

1. In addition to the compliance simulations for type B synchronous power-generating modules set out in Article 51, type C synchronous power-generating modules shall be subject to the compliance simulations detailed in paragraphs 2 to 5. Instead of all or part of those simulations, the power-generating facility owner may use equipment certificates issued by an authorised certifier, which must be provided to the relevant system operator.

2. With regard to the LFSM-U response simulation the following requirements shall apply:

(a) the power-generating module's capability to modulate active power at low frequencies in accordance with point (c) of Article 15(2) shall be demonstrated;

(b) the simulation shall be carried out by means of low frequency steps and ramps reaching maximum capacity, taking into account the droop settings and the deadband;

(c) the simulation shall be deemed successful in the event that:

(i)

the simulation model of the power-generating module is validated against the compliance test for LFSM-U response described in of Article 45(2); and

(ii)

compliance with the requirement of point (c) of Article 15(2) is demonstrated.

3. With regard to the FSM response simulation the following requirements shall apply:

(a) the power-generating module's capability to modulate active power over the full frequency range in accordance with point (d) of Article 15(2) shall be demonstrated;

(b) the simulation shall be carried out by simulating frequency steps and ramps big enough to trigger the whole active power frequency response range, taking into account the droop settings and the deadband;

(c) the simulation shall be deemed successful in the event that:

(i)

the simulation model of the power-generating module is validated against the compliance test for FSM response described in Article 45(3); and

(ii)

compliance with the requirement of point (d) of Article 15(2) is demonstrated.

4. With regard to the island operation simulation the following requirements shall apply:

(a) the power-generating module's performance during island operation referred to in the conditions set out in point (b) of Article 15(5) shall be demonstrated;

(b) the simulation shall be deemed successful if the power-generating module reduces or increases the active power output from its previous operating point to any new operating point within the P-Q-capability diagram within the limits of point (b) of Article 15(5), without disconnection of the power-generating module from the island due to over- or underfrequency.

5. With regard to the reactive power capability simulation the following requirements shall apply:

(a) the power-generating module's capability to provide leading and lagging reactive power capability in accordance with the conditions set out in points (b) and (c) of Article 18(2) shall be demonstrated;

(b) the simulation shall be deemed successful if the following conditions are fulfilled:

(i)

the simulation model of the power-generating module is validated against the compliance tests for reactive power capability described in Article 45(7); and

(ii)

compliance with the requirements of points (b) and (c) of Article 18(2) is demonstrated.

Article 53 U.K. Compliance simulations for type D synchronous power-generating modules

1. In addition to the compliance simulations for type B and C synchronous power-generating modules set out in Articles 51 and 52, except for the simulation of fault-ride-through capability of type B synchronous power-generating modules referred to in Article 51(3), type D synchronous power-generating modules are subject to the compliance simulations set out in paragraphs 2 and 3. Instead of all or part of those simulations, the power-generating facility owner may use equipment certificates issued by an authorised certifier, which must be provided to the relevant system operator.

2. With regard to the power oscillations damping control simulation the following requirements shall apply:

(a) it shall be demonstrated that the power-generating module's performance in terms of its control system (‘PSS function’) is capable of damping active power oscillations in accordance with the conditions set out in paragraph 2 of Article 19;

(b) the tuning must result in improved damping of corresponding active power response of the AVR in combination with the PSS function, compared to the active power response of the AVR alone;

(c) the simulation shall be deemed successful if the following conditions are cumulatively fulfilled:

(i)

the PSS function damps the existing active power oscillations of the power-generating module within a frequency range specified by the relevant TSO. That frequency range shall include the local mode frequencies of the power-generating module and the expected network oscillations; and

(ii)

a sudden load reduction of the power-generating module from 1 pu to [F1 0.6] pu of the maximum capacity does not lead to undamped oscillations in active or reactive power of the power-generating module.

3. With regard to the simulation of fault-ride-through capability of type D synchronous power-generating modules, the following requirements shall apply:

(a) the power-generating module's capability to provide fault-ride-through in accordance with the conditions set out in point (a) of Article 16(3) shall be demonstrated;

(b) the simulation shall be deemed successful if compliance with the requirement laid down in point (a) of Article 16(3) is demonstrated.
