Introduction
After total or partial blackout incident, black start capability of generating units in
each region is required to re-start themselves without external supply sources and then
initially supply electricity to other power plants and supply some load in their region to
bring the system back to normal condition in the limited time. Then, there shall be
generating plants black start requirements standard to ensure that black start services
are provided in case of emergency.
Objective
- Establish black start capability plan which already integrated in the blackout
restoration manual after total or partial blackout incident. Black start capability
plan shall define appropriate quantity and location of system black start
generators.
- To ensure that black start capability plan is applicable in case of emergency.
- Black start capability plan has to be reviewed and updated regularly to ensure
that the plan is always ready to use.
Definition
- Necessary load:
The electricity requirement of communication system and station service
of control centers or high voltage substations.
Requirement
Regional reliability organizations or control centers shall coordinate with each
other as appropriate to define appropriate quantity and location of system black start
generators and to develop black start capability plan in order to bring the system back
to normal condition in the limited of time after total or partial blackout incident.
The black start capability plan shall include:
1. Conduct database that contains all black start generators designated for use
in system restoration plan in respective areas by define:-
- Name
- Location
- Dependable capacity (MW)
- Type of unit
- Starting method
- Latest date of black start test
This database must be updated on an annual basis.
2. Demonstration of black start units to perform their intended functions as
required in the regional system restoration plan which shall be met through
simulation or testing method.
