Abstract:

详细论述了准稳态(quasisteadystate,QSS)仿真和基于参数连续化技术的准稳态(continuationbasedquasisteadystate,CQSS)仿真方法的基本思想。以3机10节点和新英格兰10机39节点系统为例,根据长期动态过程仿真结果对2种方法进行了比较分析,论证了在QSS仿真中引入负荷参数连续化思想的可行性,避免了求解描述动态负荷恢复过程的微分方程,缩短了计算时间;同时通过先预测后修正的方法提高了QSS仿真的收敛速度,即使系统运行点接近奇异诱导分歧点,通过选择适当的连续化参数仍能保持良好的收敛性。此外CQSS的仿真精度受发电机过励磁和电枢电流限制的影响。
