Article 143 Frequency restoration process

United Kingdom

The control target of the FRP shall be to regulate the FRCE towards zero within the time to restore frequency.

The FRCE is:

(a)

the ACE of an LFC area, where there is more than one LFC area in a synchronous area; or

(b)

the frequency deviation, where one LFC area corresponds to the LFC block and the synchronous area.

The ACE of a LFC area shall be calculated as the sum of the product of the K-Factor of the LFC area with the frequency deviation plus de subtraction of:

(a)

the total interconnector and virtual tie-line active power flow; and

(b)

the control program in accordance with Article 136.
