3 Terms and definitions

The following terms and definitions apply to this document.

3.1 Adequacy (ofanelectricpowersystem)

Within the system component rating, the bus voltage and system frequency are kept within allowable limits, taking into account planned and unplanned outages

When the power system in steady-state conditions to provide users with all the necessary power and capacity.

Note. This ability can be measured using one or more suitable indicators.

[GB/T 2900.13-2008, Definition 191-21-01]

3.2 Unit maximum capacity

Power unit When all the components of the unit are in normal working condition, the maximum power that may be emitted in continuous operation.

Note. This power can be total output power and can be net output power.

[GB/T 2900.52-2008, Definition 602-03-08]

3.3 Contingency

Usually includes one or more component failure, and at least an instantaneous impact on the interconnected power system events.

3.4 Demand

The magnitude of the electricity supply in kilowatts or kVA.
