摘要:

依托某发电厂2×660 MW空冷机组工程,应用电力瞬时分析程序(electrical transient analysis program,ETAP)对该电厂的电气系统暂态稳定性进行了仿真计算。针对多种可能的操作及故障(发电机切除,400 、10、0.4 kV 母线故障并清除,大功率电动机启动、切除及再启动,快切动作等)对厂用电系统造成的影响进行了分析研究。通过仿真波形,直观形象地反映了厂用电系统的暂态过程,为发电厂电气系统的设计提供了有力的技术支持。

Abstract:

The simulative calculation of a transient stability is performed by an electrical transient analysis program(ETAP) for a 2×660 MW coal fired power plant. Several conditions including fault and operation which may cause a big influence on the auxiliary power system of power plant are studied. The transient process is shown clearly by simulated waveform. The results give a strong support to the electrical system design of power plant.
