摘要
提出了一种计及系统频率特性的分布系数方法。该方法合理地考虑了因发电机开断而频率变化对潮流分布的影响。算例表明:在电力系统预想事故评定中,该方法既保证了发电机开断模拟的快速性,又提高了计算精度。
A method of generation distribution factor which considers the frequency charcteristic for power system contingency evaluation is presented. The method reasonably considers the influence of frequency change caused by generator outage on load flow distribution. An example its given, and its result shows that the method not only ensures the fast speed for generator outage simulation, but also improves the calculation accuracy in power system contingency evaluation.
