CHAPTER IIIRESTORATION PLAN

SECTION 4 Resynchronisation

Article 33Appointment of a resynchronisation leader

1.

During system restoration, when two synchronised regions can be resynchronised without endangering the operational security of the transmission systems, the frequency leaders of these synchronised regions shall appoint a resynchronisation leader in consultation with at least the TSO(s) identified as the potential resynchronisation leader and in accordance with paragraph 2. Each frequency leader shall inform without delay the TSOs from its synchronised region of the appointed resynchronisation leader.

2.

For each pair of synchronised regions to be resynchronised, the resynchronisation leader shall be the TSO that:

(a)

has in operation at least one substation equipped with a parallel switching device on the border between the two synchronised regions to be resynchronised;

(b)

has access to the frequency measurements from both synchronised regions;

(c)

has access to the voltage measurements on the substations between which potential resynchronisation points are located; and

(d)

is able to control the voltage of potential resynchronisation points.

3.

Where more than one TSO fulfils the criteria under paragraph 2, the TSO with the highest number of potential resynchronisation points between the two synchronised regions shall be appointed as the resynchronisation leader, unless the frequency leaders of the two synchronised regions agree to appoint another TSO as resynchronisation leader.

4.

The appointed resynchronisation leader shall act as such until:

(a)

another resynchronisation leader is appointed for the two synchronised regions; or

(b)

the two synchronised regions have been resynchronised, and all the steps in Article 34 have been completed.
