同步调相机对于直流工程及电力系统的电压稳定具有重要意义,研究其电力系统稳定器配置的方法,对其在进相运行时有重要意义。首先对同步调相机中的主要控制环节设备建立数学模型;然后以发电机稳定为目标,研究在各种无功出力下阻尼变化趋势,建立同步调相机运行模型;最后论证了同步调相机配置电力系统稳定器的必要性和可行性。算例表明,与不配置电力系统稳定器的调相机相比,含励磁控制和限制环节的方法更完善,且能满足各个工况的动态要求,具有较强的实用性。

The synchronous condenser is of great significance for DC engineering and voltage stability of power system.The research on the configuration method of power system stabilizer is of great significance for its leading phase operation.Firstly,the mathematical model of the main control link equipment in the synchronous condenser is established.Then,aiming at the stability of generator motor,the variation trend of damping under various reactive power output is studied,and the operation model of synchronous condenser is established.Finally,the necessity and feasibility of configuring power system stabilizer with synchronous condenser are demonstrated.The calculation example shows that,compared with the condenser without a power system stabilizer,the method including excitation control and limiting links is more complete,and can meet the dynamic requirements of various working conditions,and has strong practicability.
