Analysis and Simulation of Angle Difference of 600 MW Thermal Unit Auxiliary Supply
For 600MW thermal power unit,there is generally a larger angle difference than other thermal unit during unit auxiliary supply switching.To ensure a reliable switching and the equipment safety,such factors as grid structure,operation mode and system voltage level are discussed in this paper.As a example simulation on No.3 Yangluo thermal power plant is also presented.The analysis ard simulation can be used for reference on design and operation of 600MW thermal power unit auxiliary supply.
