摘要
忽略发电机1D绕组、1Q和2Q绕组及考虑磁饱和时,利用特征值分析法和复转矩系数法计算了发电机组在次同步频率范围内的电气阻尼特性曲线和特征值,分析了发电机模型对交直流并列运行系统次同步振荡(SSO)阻尼特性的影响。研究表明忽略发电机D绕组对分析系统SSO发生的趋势几乎无影响,但忽略发电机Q绕组和磁饱和则在研究发电机组SSO阻尼特性时发生谐振的频率范围加大,利于采取抑制SSO的措施。
By a complex torque coefficient method and eigenvalue method, without considering some windings in generator and magnetic saturation, the subsynchronous oscillation （SSO） damping characteristics and eignevalues are studied. The results reveal that the subsynchronous oscillation （SSO） damping characteristics are no different with or without considering d windings. However, when the model of q windings and magnetic saturation of generator is neglected , the range of frequency which has danger in SSO will become wider, which is favourable for analyzing the measurements to restrain the SSO.
