托克托电厂发电机组轴系扭振参数测试

Generator Rotor Shaft Torsion Parameter Identification Test in Tuoketuo Power Plant

近年来，为了提高电网的输送能力，串联电容补偿技术被广泛采用。借鉴发达国家电网运行经验，在串联电容补偿的输电系统中发电机组轴系与电网之间的次同步谐振问题（即SSR）引起了广泛关注。为了准确评估托克托电厂的SSR问题，进行了托克托电厂发电机组轴系扭振参数测试试验。2007年1月12日～13日在国内首次完成该试验。介绍了试验方案、现场试验结果、仿真分析以及结论。

The technique of series capacitor compensation had been applied recently to improve transmission ability of power grid. According to experiences of international power grid operation, sub-synchronous resonance （SSR） between rotor shaft of generator and power network in series capacitor compensated transmission project had been paid attention widely. To judge the SSR of Tuoketuo Power Plant more exactly, it was decided to do the generator torsion parameter identification test which is the first time in China. In January 12 and 13, the test had been done successfully. In this paper,test method,test result and simulation analysis had been introduced. At last ,some conclusion was gained.
