为了全面分析励磁系统在电网故障时对电力系统稳定的影响，采用励磁系统主控制模型与励磁附加限制环节模型结合的方法测试不同工况下电力系统运行变化。通过分析与建模，选取典型参数、仿真阶跃扰动、近端短路等方式在仿真实验系统中进行了模拟验证。结果表明：低励限制、过励限制等附加功能参数的设置直接影响电力系统稳定水平，该方法能够更全面地反映励磁系统对电力系统的影响，可以为优化励磁控制策略、提升电网稳定水平提供指导。

In order to comprehensively analyzing the influence of additional restriction function for generator excitation system on the power system stability when the power grid breaks down,tests the power system response in different condition by combining the excitation system main control model with the additional restriction tache model,and by analysis,modeling,selecting typical parameters, simulating the step disturbance and near-to generator short circuit,validates the result of test. The result shows that the additional restriction function can affect the power grid stability. The method can fully reflect the influence of excitation system on the power system,and provide reference for optimizing excitation control strategy.
