摘要(Abstract)：

针对500 kV瓯海变直流系统存在的问题,提出了具体的改造方案和施工流程,并在获得专利的"变电站直流系统不停电改造装置"的基础上进一步创新,组建了1套临时直流系统,应用于500 kV变电站直流系统不停电改造,确保了电网的安全可靠运行。
Aiming at the problems of DC system of 500 kV Ouhai substation,this paper puts forward specific transformation scheme and construction process.On the basis of the obtained patent of Device for Non-outage Transformation of DC System of Substation,further innovations are made,and a temporary DC system is established and used in non-outage transformation of DC system of 500 kV substation to assure safe and reliable operation of power grid.
