洪屏抽水蓄能电站500kV电气主接线设计分析

Design and Analysis of 500kV Electrical Main Connection for Hongping Pumped-Storage Power Station

随着“双碳”目标的提出,抽水蓄能电站的建设得到迅猛发展。电气主接线设计是整个抽水蓄能电站设计中最为重要的部分之一,电气主线是否能安全可靠地运行直接影响抽水蓄能电站的稳定性和经济性。文章以洪屏抽水蓄能电站二期工程为例,从技术的先进性、应用的灵活性、运行的可靠性和工程的经济性等方面,对其500kV电气主接线设计方案比选过程进行详细介绍,以期为类似工程提供参考。

With the proposal of the“dual-carbon”target,the construction of pumped-storage power stations has been rapidly developed.The design of electrical main connection is one of the most important parts of the entire pumped-storage power station design.The safety and reliability of the electrical main connection directly affect the stability and economy of the pumped-storage power station.Taking the second phase of the Hongping Pumped-Storage Power Station project as an example,this paper provides a detailed introduction to the selection process of the 500kV electrical main connection design scheme from aspects such as whether the technology is advanced,whether the application is flexible,the reliability of operation,and the economy of the project.This is intended to provide reference for similar projects.
