摘　　要：哈达山水利枢纽由拦河土坝、16孔溢流坝、河床式电站、混凝土重力坝、引水渠首闸、上游库区左岸防护堤等水工建筑物,机组台数较多,同时用电负荷数量多,种类繁杂,分布范围广,性质重要,供电距离长,对供电的可靠性要求高。本文结合工程实际情况,对电气主接线、厂坝区供电接线、主要电气设备选择、主变压器及66 kVGIS开关站布置等进行了论述,提出合理技术方案。所有设备技术参数均完全满足长期运行和三相短路工况的要求,且电站已运行多年,运行维护方便,可靠性高,满足东北电网要求。The Hadashan hydro-junction project consists of the earth dam, 16 over flow dam sections, river power station, concrete gravity dam, diversion canal head gate and left bank protection embankment in upstream reservoir region. It needs the high reliability for the power supply because of that has more units, varies and important large quantity electricity load with the wide distribution and the long power supply distance. According to the actual situation of the project, the paper discusses the the main electrical connection, the power supply connection in station and dam region,the main electrical equipment selection,the layout of the main transformer and 66 KV GIS switching station, puts forward the reasonable technique scheme. All of the equipment technique parameters meet the requirements of long-term operation and three-phase short-circuit operating condition. Running with the many years, now the power station is easy operation maintenance and high reliability,which could meet the requirement of the NorthEast China Grid Company.
