求助四机两区域动态仿真
潮流结果和PSASP的完全对得上，但在不设故障情况下在0.17s失稳，G1的Pelec如图lofl

潮流数据预处理应该没问题，dyr文件只包括发电机模型，用PSASP6型模型仿真结果正常，到PSS/E就出问题了
最后两项饱和度是自己随便写的，其他数据来自kunder的书 问题很明显，你在执行STRT初始化操作时提示：
Executing activity STRT
GENROU AT BUS 1 MACHINE 1 : X'' =0.25000 IM(ZSORCE) =1.00000
GENROU AT BUS 101 MACHINE 1 : X'' =0.25000 IM(ZSORCE) =1.00000
GENROU AT BUS 201 MACHINE 1 : X'' =0.25000 IM(ZSORCE) =1.00000
GENROU AT BUS 301 MACHINE 1 : X'' =0.25000 IM(ZSORCE) =1.00000
这表明，你在潮流数据中的ZSORCE（CONG操作中将发电机等效为Norton电流源就是用的这个ZSORCE）与动态仿真中的发电机的次暂态电抗X"不相等。两个不相等，仿真就是错的。
这就是问题的所在。
看起来你的X"可能是对的，ZSORCE用的的默认值1.0，那么将潮流数据中发电机的ZSORCE的电抗值改为对应X"就可以了。 厉害！！！光看INITIAL CONDITIONS CHECK O.K.去了
多谢::handshake:: 学习一下。 看不懂呀 强啊强啊强啊强啊强啊 谢谢！谢谢！谢谢！ 同问，哪位大神指教一下？
