摘要(Abstract):
双馈风力发电机通过串联补偿线路外送风电时,会出现由感应发电机效应(induction generator effect,IGE)和次同步控制相互作用(sub-synchronous control interaction,SSCI)引起的次同步振荡问题。为分析该问题,以给其抑制措施提供依据,建立了用于次同步振荡分析的双馈风力发电机模型,采用频率扫描法分析了IGE的机理和影响因素,从转子侧电流环的闭环控制角度推导分析了SSCI的机理和影响因素,并采用时域仿真法分别分析和验证了风速、串补度对IGE的影响及转子侧电流环控制参数对SSCI特性的影响。研究结果表明:串补度的增加和风速的减小会引起IGE;电流环控制器比例系数和积分系数的增大会引起SSCI。
