摘要
发电机组误强励现象时有发生,对于系统稳定造成严重危害,因此对于该现象的认识及预防尤为重要。基于凸极同步电机的派克方程,在MATLAB里搭建单机无限大系统,进行强励过程的暂态仿真,分析了定子电流、电压、功率及转速的暂态过程。
The de-excitation of generator occurred frequently in recent years, it took serious damage to system stability, so it is particularly important to study this phenomenon and seek prevention. Based on Park equations of synchronous generator, construct a model of stand-alone generator in infinite system, simulate the transients state on exciting voltage stepping, analyse the danamie process of stator current, voltage, power and speed.
