| 摘 要： | 对国家电网公司750 kV输变电示范工程2006年1月至2007年6月期间损耗电量及损耗率进行了统计,分析了其构成及变化特征,指出在电量计量方面可能存在超标误差,导致750 kV官亭变向兰州东变输送电量时出现零损,甚至负损;分析了750 kV输电线路在运行初期输送功率较低的情况下,输送电量与线路损耗率之间的关系曲线,推算出使750 kV输电线路损耗率最低的运行电流(功率)。

| Abstract: | North west 750 kV power grid is the first 750 kV power project in China,which is installed in Sep.2005.During the initial operation stages of north west 750 kV power grid,because of low transmission power,the lost is much higher than normal.The paper analyzes each part loss of 750 kV power grid,it includes transformer,shunt reactor,transmission conduct and substation loss.The conclusion can be drawn that transnormal errors maybe occur among measurement instruments,and the economic transmission power can make grid loss lowest. |
