摘要
东北电力系统中的伊敏发电厂前两期工程装机容量２０００ＭＷ，需经过约５００ｋｍ的５００ｋＶ线路送电至负荷中心大庆地区。因送电距离远、输电容量大，存在系统稳定问题。采用串联补偿技术，对节省送变电工程投资，提高系统稳定性是一有效方法。本文针对该系统的串联补偿方案，进行了串补站位置、串联补偿度、串联电容器的保护方式以及次同步谐振等问题的研究。
Four sets of 500 Mw generator will be installed in planned Yimin power plant in northeast power system ofchina by two stages and the output of which will be transmitted to the load center, the Daqin area,by 500kV lineat distance about 500 km. In this paper the locations of series capacitor, series compensation degree,overvoltageprotective schemes of capacitor bank and subsynchronous resonance(SSR)are studied for Yimin-Daqing 500kVpower system with series compensation.
