摘要
引汉济渭子午水电站是引汉济渭工程的调蓄中枢,电站安装2台抽水蓄能机组和2台常规机组,兼顾发电、抽水两大工况,库区水头变化范围大,运行工况复杂,为满足工程经济性要求,电站设计安装了 2台西门子完美无谐波变频器,能够满足低水头下的变频发电和低扬程下的变频抽水,可为类似案例提供借鉴.
Abstract
The Ziwu hydropower Station is the regulatory center of the Hanjiang-to-Weihe river valley water diversion project,two pumped storage units and two conventional units are installed in the power station,it takes into account the two working conditions of power generation and pumping,the water head in the reservoir area has a wide range of changes,operation conditions are complex,in order to meet the economic requirements of the project.The power station has been designed and installed 2 Siemens perfect harmonic-free frequency converters.The utility model can meet the requirements of frequency conversion power generation under low water head and frequency conversion pumping under low lift.
