Abstract:

针对大型汽轮发电机接入串补输电系统面临的次同步谐振问题,研制出一种基于电力电子变流器的机端次同步阻尼控制器(generatorterminalsubsynchronousdampingcontroller,GTSDC)。它由多模态次同步阻尼控制器和基于链式结构的高压大容量电流跟踪变流器构成,通过向机组定子侧注入幅值和相位可控的扭振模态互补频率的电流,实现抑制轴系扭振的目标。阐述GTSDC的工作原理和设计方法,研发一套等效容量为10MVA、输出电压为22kV的装置,并在上都电厂660MW机组上进行现场参数整定和效果试验,结果表明:所研发的GTSDC能大幅提高扭振模态阻尼并有效抑制持续激励引发的强迫性轴系扭振,为解决次同步谐振和振荡问题提供了一种新颖而有效的技术手段。
