摘要
提出小型水电站接入系统的方案,包括送出电压等级,出线回路数,电站电气主接线,电站上网引起110千伏电网改建等。提出三种改造方案,通过方案的技术经济比较认为,方案一可作为新建水电站接入系统后城网改造方案,如果近期负荷有较大增长,不排除方案二的可能性。
This paper refers the small hydropower station access system scheme, which is including the transmission voltage level, the number of transmission line circuits, the main power station electrical wiring, and the transformation of 110 kV power grid caused by the conversion. Three transformation programs are put forward, and scheme is taken for network after the new hydropower station is united to system. If a greater load growth exists in the near future, the possibility of scheme Ⅱ is not excluded.
