摘　　要：根据关口实测电量计算了近3年特高压交流示范工程实际电能损耗,并综合考虑电阻损耗和电晕损耗,将负荷曲线分段等效,提出了一种基于PSASP潮流计算的损耗率理论综合计算方法.该方法通过计算最大负荷利用时间和等效电阻损耗小时数,可以将瞬时性的功率损耗率修正为电能损耗率.理论计算值与实际值对比结果表明:该方法准确度较高,在工程上具有一定的意义,最后分析了两者之间误差的来源.First the true values of UHVAC system loss rate in recent three years are calculated according to the gateway measurement data.Then,by achieving equivalent load curve,considering both resistance loss and corona loss,this paper proposes a new loss rate calculation method based on PSASP power flow calculation.This method can convert momentary power loss rate into energy loss rate by calculating the maximum load availability time and resistance loss hours.The comparison between the theoretical value and actual value shows that this new method has a high accuracy and a certain practical significance.The sources of error are analyzed at last.
