C Itong匕u xleZhen次同步谐振(subsynehronous resonance)当有串联电容补偿的电力系统受到扰动发生电感电容谐振，其谐振频率与透平发电机组的抽系扭振某一振型的频率互补，即两者之和接近或等于系统的同步频率时所发生的谐振。透平发电机组的轴系有透平机的各级转子和发电机及励磁机的转子，它们构成像用弹黄连接的多质t扭转振荡系统，其固有自由振荡频率几有好几个，而且低阶振型的频率往往低于电力系统的同步频率人。当透平发电机组发生轴系扭振时，发电机的转子磁场对电枢来讲是以f.士几频率旋转，电枢电流也就有这两个频率。当电力系统的电感电容谐振频率人接近或等于f.一fm时，就会发生次同步谐振。电力系统的电磁谐振与透平发电机组轴系扭振互相激励，致使轴系扭转应力增大，严重时可使发电机的转轴遭受损害。在70年代初，美国莫哈维(Mohave)电厂曾先后发生过两次次同步谐振，两台发电机的发电机和励磁机之间的轴段先后发生严重的裂纹。 防止次同步谐振的对策有，在转子上加装阻尼绕组，或在升压变压器中性点加装阻塞滤波器组，但投资昂贵;也有在励磁系统上加装电力系统德定器的。但后来发现快速励磁系统加装电力系统稳定器时，如选择配置不当，多机的稳定器互相干扰，还是不能防止次同步谐振。最近根据最优控制原理设计的一种线性最优励磁控制(LOEC)，投资较省，效果最好。防止次同步谐振的最经济有效的措施仍在研制中。 近来还发现调整直流箱电的功率时，或有申联补偿的电力系统切除故障重合闸后，也可能引起次同步谐振。因此，最近对大容量透平发电机加装扭转振动监测装置，有次同步谐振报警器和扭转应力分析仪，对次同步谐振的振动转矩对转轴寿命的影响进行分析并记录。
