单站双向调水泵站改造前后能效分析
Comparative Analysis of Energy Efficiency before and after Renovation of a Bidirectional Water Transfer Pumping Station
摘要
Abstract
The Guanbu Pumping Station supplies water in two directions:to the Xiajiashan Pumping Station and to the Hexi Reservoir.The head difference between these directions forces the system to rely on valve throttling for flow distribution,causing energy losses exceeding 28%of the pump head and cavitation risks during low-water-level operation.To address these issues,the system was redesigned into two independent one-way pipelines equipped with variable-frequency drives for flexible regulation.An evaluation model was developed based on hydraulic characteristics and operational constraints to analyze energy efficiency and optimal scheduling before and after the retrofit.Results showed that efficiency toward Hexi remained nearly unchanged,whereas the Xiajiashan direction avoided throttling losses,improved energy efficiency by 2.7%～10.2%,and eliminated cavitation risks.The findings provide a valuable reference for energy-saving retrofits and operational optimization of similar pumping stations.关键词
