重庆市中梁水电站220kV接入系统方案优化调整

Optimal Adjustment of 220kV Access System of Zhongliang Hydropower Station

中梁水电站总装机122MW,由于受外部建设环境变化等诸多因素影响,原接入系统方案存在技术、投资等方面的问题。因此,有必要对原接入系统方案进行优化调整,调整后的接入系统方案除能满足接入电力系统要求外,还可节省工程投资,减少110kV输电线路电能损失,缩短220kV集中升压站建设工期。

The total installed capacity of Zhong-liang hydropower station is 122MW, However, due to the changes of built environmental and many other external factors, there have some problems of the original program. Therefore, it is necessary to optimize the original access system programs. After optimal adjustment, the access system can meet the requirement of accessing power system. And it also can save investment, reduce power losses of 110kV transmission line, and shorten construction period of 220kV booster station.
