| Abstract: | Configuring series compensation with capacitors in long distance high capacity transmission lines can enhance power transfer capability of power systems,however it may cause subsynchronous resonance(SSR) that jeopardize the security of unit shafting and stability of power system.The authors expound the mechanism of SSR and existing mitigating measures,and the principles,functions and economy of several measures,which are commonly adopted in practice to mitigate SSR,are analyzed and compared;then the advanta... |
