惠南庄泵站水泵调速运行的合理性分析 Analysis on rationality of speed-regulating operation of pumps in Huinanzhuang Pumping Station
水利水电技术第40卷2009年第7期 惠南庄泵站水泵调速运行的合理性分析 戚兰英1,戴 昆2,蒋 瑞1,侯 治1 (I.北京市水利规划设计研究院,北京100048;2.南水北调中线管理局,北京100038) 摘要:惠南庄泵站采用大型卧式离心泵,变频调速运行。为满足南水北调中线工程(北京段)复杂 的调水需求.合理地组合调速运行方案,确定可行的调速范围,使泵站机组高效、安全、稳定运行。 文中重点分析了通过机组调速运行的优化组合,结合泵站小流量自流输水,实现北京段输水流量过程 的无缝衔接。 关键词:南水北调工程;高扬程泵站;流量;调速分析;经济运行 中图分类号:TV675(21)文献标识码:B 文章编号:1000-0860(2009)07—0070-06 on of of in Station Analysisrationalityspeed-regulatingoperationpumpsHuinanzhuangPumping Zhil Kun2,JIANGRuil,HOU QI胁-yin91,DAI Instituteof (1.Beijing Water,Beijing100048,China; 2.AdministrationBureauofSouth·to-NorthWaterDiversionMiddleRoute Project,Bering100038,China) horizontal unitsare underthe Abstract:In Station,large·scale installed,whichoperate HuinanzhuangPumping centrifugalpump modeof with CORVerteLInordertomeetthe waterdiversion oftheMid·route speed-regulatingfrequency complicated requirement theSouth—to—NorthWaterTransfer schemeis inte- Section)of speed—regulatingoperation reasonably Project(Beijing Project,the to withthedeterminationofthefeasible astoenablethe units with range,80 pump operatehishefficiency gated speed·regulating of of transfer of undersafeandstable realizationtheseamless thewater condit
