Simulation of Auxiliary Power System Operating State for 600 Mw Air-Cooling Unit

摘要

At present, 600MW high-capacity unit is the main of auxiliary power system, there are many loads and complex wirings, as the auxiliary power system operating state plays an important role, so it is very important to simulate the operation of system and analyze the reliability of all buses and short-circuit current. The latest engineer-designing software (ETAP) of auxiliary power system is used in this paper, the model of this system is established to simulate the operating state, then the reliability, power flow, short-circuit current, motor starting checkout, power consumption rate are calculated, Operating state is analyzed, and all the calculated data will provide a basic reference for the future designing.
