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.关键词
