Power / Controls
The function of the nuclear standby generator is to provide power for Class III loads, in the event of loss of Class IV power. The standby generator must be capable of supplying power of a certain distribution voltage (typically 13.8kV) at synchronous speed (60 Hz) within a short time (typically 2.5 minutes) and of taking load at certain power every short period (such as 1.2MW every 10 seconds). The standby generator must have black start capability and certain days (typically 4 days) of black-out emergency load capability. At least the standby generator must be capable of supplying power to provide safe plant shutdown. Typically three standby generator sets are needed, as determined on the contingency that one set may be out for maintenance and one may fail to start. Due to the emergency function of the standby generator sets, protection and control circuits are designed to provide alarm rather than to trip where possible in order to avoid tripping the standby generator unnecessarily. Standby generators must be capable of being connected in parallel with the distribution system and with each other.
The objective of this project is to design a nuclear standby generator control and protection system that ensure the standby generator is capable of supplying power to Class III loads for a period of time, in event of loss of Class IV power.
Design a standby generator that is capable of supplying power to Class III loads at 13.8kV within 2.5 minutes after Class IV power is interrupted and is capable of taking loads at 1.2MW every 10 seconds up to 50MW.
Design the standby generator that has a black start capability and is capable of providing 4 days of black-out emergency power to Class III loads.
