白山抽水蓄能电站是国内首次自行设计、施工建设的大型抽水蓄能电站。蓄能电站装有2台单机容量150 MW的可逆式机组,机变组采用单元接线,通过左岸地面电站2回220 kV架空线并入东北电网联网。首台蓄能机组经过国际招标引进了国外先进技术和设备,成功消化吸收主机设备的设计、制造、安装、调试等方面的技术经验,应用在国产化150 MW抽水蓄能机组。文中对白山抽水蓄能机组的系统接线方式、电气一次、电气二次和机械部分设计进行介绍,总结蓄能机组投产初期暴露出的问题。
Baishan Pumped Storage Power Station is the first large-scale pumped storage power station designed and constructed in China. The energy storage station is equipped with two reversible units with a capacity of 150 MW. The unit is connected with the unit through two back-to-back 220 kV overhead power lines on the left bank of the earth station and is integrated into the Northeast Power Grid. The first accumulator unit imported advanced foreign technology and equipment through international bidding and successfully digested and assimilated the technical experience in design, manufacture, installation and commissioning of the host equipment and applied it to the localization of 150 MW pumped storage units. This paper introduces the system wiring of Baishan pumped storage unit, the electrical first time, the second time of electrical parts and the design of mechanical parts, and summarizes the problems exposed during the initial operation of the storage unit.
