关于临沂换流站调相机接入系统关键问题的研究

Research on Key Issues of Rotary Condenser Access System of Linyi Converter Station

配合上海庙-山东±800 kV特高压直流输电工程增设调相机的必要性,采用中国电力科学研究院PSD-BPA潮流及稳定计算软件,从提升系统稳定性和技术经济性等不同角度对调相机接入系统方案中电压等级、接入站点、升压主变调压方式等多个方面进行研究,推荐调相机采用无励磁调压变压器以500 kV电压等级接入临沂换流站500 kV侧配置方案,对于保障上海庙-山东±800 kV特高压直流工程安全稳定运行具有工程意义。

This paper introduces the necessity to coordinate Shanghaimiao-Shandong ± 800 kV HVDC Transmission Project in addition of rotary condenser,uses PSD-BPA currents and stability calculation software of China Electric Power Research Institute to research voltage classes,access site,boosting main transformer primary voltage regulating mode and other aspects of rotary condenser access system scheme from the perspectives of enhancing the system stability and technological economy and so on,recommends the rotary condenser should use off-circuit-tap-changing transformer for access to Linyi Converter Station 500 kV side configuration program with 500 kV voltage class,which has engineering significance for the safe and steady operation of Shanghaimiao-Shandong ±800 kV HVDC project.
