根据高港泵站长江侧抽排、抽引季节的潮位变化情况 ,确定泵站运行扬程 ,分析 1～ 3号半调节机组调速运行的效益。结果表明 ,采用变频调速经济上是可行的 ,并可增大排涝流量近 8m3/s。
Based on the pumping schedule at the Yangtze River side of the pumping station of the port and pumping stations, the change of the tide level in the pumping season is determined, and the lift of the pump station is determined. The benefit of speed regulation operation of the semi-regulating units No.1 ~ 3 is analyzed. The results show that the use of variable frequency speed control is economically feasible, and can increase drainage flow of nearly 8m3 / s.
