新疆某供水工程供电设计方案

Power Supply Design Scheme of a Water Supply Project in Xinjiang

某供水工程年供水时间为12个月,供水保证率为95%,沿线设多座供水泵站,其中2#泵站、1#泵站、7#泵站、8#泵站4座泵站容量较大,且位置相对集中。文章结合当地电网情况,对上述4座泵站提供两个相对独立的110 kV电源,由4座泵站两侧接入,采用逐级串接双链路供电的方式连接4座泵站,两回电源取自4座泵站两侧的20 kV变电站。两路电源在各级泵站之间形成环形供电接线形式,保证每级泵站均有2个供电电源,且每回线路均能满足本泵站的负荷要求,满足供配电规范要求,保证供水、供电可靠性。

A water supply project has an annual water supply time of 12 months and a water supply guarantee rate of 95%.There are several water supply pumping stations along the line,including 2#pumping stations,1#pumping stations,7#pumping stations,and 8#pumping stations.The station has a large capacity and a relatively concentrated location.Based on the local power grid,the article provides two relatively independent 110 kV power supplies for the above 4 pumping stations,which are connected by both sides of the 4 pumping stations,and adopt a cascaded dual-link power supply.The four pumping stations are connected in this way,and the two power sources are taken from 20 kV substations on both sides of the four pumping stations.Two power sources form a loop power supply wiring form between pump stations at all levels,ensuring that each pump station has two power supplies,and each circuit can meet the load requirements of the pump station.Meet the requirements of power supply and distribution specifi cations,and ensure the reliability of water supply and power supply.
