摘　　要：为消除泵站设备隐患和缺陷,保障泵站主机组安全稳定可靠运行,以南水北调惠南庄泵站机组为例,通过研究分析和有针对性地实施专项改造项目,自主实施计算机监控系统程序及主变频器参数优化,消除历次停机固有隐患,有效地提升了泵站安全稳定运行,尤其是针对原停机连锁程序缺陷、抵御外电网电压暂降能力低及电机开式冷却水导致的过滤器堵塞停机等缺陷,提出改进措施,对后期国家水网调水泵站工程建设运行有重要指导意义。In order to eliminate the hidden dangers and defects of the pumping station equipment from the source,ensure the safe,stable and reliable operation of the pumping station host unit,and ensure the drinking water safety of the capital,taking the pumping station unit of the South-to-North Water Transfer Project as an example,through research and analysis and targeted implementation of special renovation projects,while independently implementing the computer monitoring system program optimization and main frequency converter parameter optimization,eliminating the inherent hidden dangers of previous shutdowns,greatly improving the pump for the safe and stable operation of the station,especially for the defects of the original shutdown chain procedure,such as the low ability to withstand the voltage sag of the external power grid and the filter blockage caused by the open cooling water of the motor,the radical measures are proposed,which have great guiding significance for the construction and operation of the national water network transfer pump station in the later stage.
