| 摘 要： | 对伊敏电厂拟安装５００ＭＷ和６００ＭＷ汽轮发电机,并通过有串联补偿的长距离５００ＫＶ输电线发入系统后的过高串补度引发的次同步谐振,进行了分析研究。研究表明,在常规串补情况下,５００ＭＷ发电机较６５００ＭＷ发电机更易被激发轴系次同步谐振,所以在串联补偿度时,前者应成为考核重点,长距离输电系统易发生次同步谐振（ＳＳＲ）,但当受端的等值阻抗值与补偿线路的阻抗值相当时,可能发生ＳＳＲ的频率秋各有１个,伊敏

| Abstract: | MW and 600MW turbine generators are installed in the Yimin Power Plant. They are connected into the electrical system via long distance 500kV transmission lines with series compensation capacitors. In order to tell how to prevent SSR, which used to be caused by over compensation, analysis is given in this paper. In the case of conventional compensation, it is proved by several ways that shaft oscillation in 500MW generators is more easily excited than that in 600MW ones. The shaft parameters of the turbine generator set are discussed. |
