Article 45 U.K. Compliance tests for type C synchronous power-generating modules

1. In addition to the compliance tests for type B synchronous power-generating modules described in Article 44, power-generating facility owners shall undertake the compliance tests set out in paragraphs 2, 3, 4 and 6 of this Article in relation to type C synchronous power-generating modules. Where a power-generating module provides black start capability, power-generating facility owners shall also undertake the tests referred to in paragraph 5. Instead of the relevant test, 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. The following requirements with regard to the LFSM-U response test shall apply:

(a) it shall demonstrate that the power-generating module is technically capable of continuously modulating active power at operating points below maximum capacity to contribute to frequency control in case of a large frequency drop in the system;

(b) the test shall be carried out by simulating appropriate active power load points, with low frequency steps and ramps big enough to trigger active power change of at least 10 % of maximum capacity, taking into account the droop settings and the deadband. If required, simulated frequency deviation signals shall be injected simultaneously into both the speed governor and the load controller references;

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

(i)

the test results, for both dynamic and static parameters, comply with point (c) of Article 15(2); and

(ii)

undamped oscillations do not occur after the step change response.

3. The following requirements with regard to the FSM response test shall apply:

(a) it shall demonstrate that the power-generating module is technically capable of continuously modulating active power over the full operating range between maximum capacity and minimum regulating level to contribute to frequency control. The steady-state parameters of regulations, such as droop and deadband and dynamic parameters, including robustness through frequency step change response and large, fast frequency deviations shall be verified;

(b) the test 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 settings of droop and deadband, as well as the capability to actually increase or decrease active power output from the respective operating point. If required, simulated frequency deviation signals shall be injected simultaneously into the references of both the speed governor and the load controller of the unit or plant control system;

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

(i)

the activation time of full active power frequency response range as a result of a frequency step change is no longer than required by point (d) of Article 15(2);

(ii)

undamped oscillations do not occur after the step change response;

(iii)

the initial delay time complies with point (d) of Article 15(2);

(iv)

the droop settings are available within the range specified in point (d) of Article 15(2) and the deadband (threshold) is not higher than the value specified in that Article; and

(v)

the insensitivity of active power frequency response at any relevant operating point does not exceed the requirements set out in point (d) of Article 15(2).

4. With regard to the frequency restoration control test the following requirements shall apply:

(a) the power-generating module's technical capability to participate in frequency restoration control shall be demonstrated and the cooperation of FSM and frequency restoration control shall be checked;

(b) the test shall be deemed successful if the results, for both dynamic and static parameters, comply with the requirements of point (e) of Article 15(2).

5. With regard to the black start capability test the following requirements shall apply:

(a) for power-generating modules with black start capability, this technical capability to start from shut down without any external electrical energy supply shall be demonstrated;

(b) the test shall be deemed successful if the start-up time is kept within the time frame set out in point (iii) of Article 15(5)(a).

6. With regard to the tripping to houseload test the following requirements shall apply:

(a) the power-generating modules' technical capability to trip to and stably operate on house load shall be demonstrated;

(b) the test shall be carried out at the maximum capacity and nominal reactive power of the power-generating module before load shedding;

(c) the relevant system operator shall have the right to set additional conditions, taking into account point (c) of Article 15(5);

(d) the test shall be deemed successful if tripping to house load is successful, stable houseload operation has been demonstrated in the time period set out in point (c) of Article 15(5) and re-synchronisation to the network has been performed successfully.

7. With regard to the reactive power capability test the following requirements shall apply:

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

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

(i)

the power-generating module operates at maximum reactive power for at least one hour, both leading and lagging, at:

• minimum stable operating level,

• maximum capacity, and

• an active power operating point between those maximum and minimum levels;

(ii)

the power-generating module's capability to change to any reactive power target value within the agreed or decided reactive power range shall be demonstrated.
