摘要(Abstract)：

研究了新一代调相机在我国特高压直流送受端的应用。首先结合直流对于调相机的技术需求,研究了调相机模型,提出基于不同时间尺度的次暂态、暂态、稳态3种运行特性。然后,基于酒泉—湖南直流风火打捆送端,从增加系统短路比、降低新能源高压脱网风险、抑制稳态过电压等角度研究了调相机在特高压直流送端的应用效果;基于华东多直流馈入受端电网,从提高直流多馈入短路比、降低多回直流同时换相失败的风险、提升严重故障下的系统电压稳定水平等角度研究了调相机在特高压直流受端电网的应用效果。最后,从设备角度提出新一代调相机在运行维护、无功响应特性等方面相较于传统调相机的技术优势,旨在为调相机后续投入工程运行提供技术支撑。
