CHAPTER 5 Compliance simulations for synchronous power-generating modules

Article 52Compliance 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:

  1. (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

  2. (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:

  1. (i)

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

  2. (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:

  1. (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

  2. (ii)

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