摘要: 针对输电网中串联电容补偿引发的次同步谐振, 采用基于时域仿真实现的复转矩系数法分析不同发电机出力以及不同串联补偿度对系统次同步振荡的影响。提出基于SVC的次同步抑制措施, 介绍相关的控制策略, 最后通过时域仿真分析加装SVC装置前后发电机组轴系转矩的变化, 验证了SVC对系统次同步振荡抑制的可行性和有效性。Abstract: For the SSR in transmission system, the complex torque coefficient approach based on time domain simulation is used to analyze the influence of different degrees of series compensation and generator putout on the SSR. A method based on SVC is proposed, and its control measures are introduced. The changes before and affer using SVC are analyzed through time domain simulation. It is verified that for SSR in power system the SVC is available and effective.
