摘要
220kV变电站的安全稳定运行,关系到整个电网的稳定,因此对变电站停电时间也有了更加严格的限制。基于此,结合直流系统改造中的实践工作,以220kV洼里变直流系统改造为例,探讨常规变电站直流系统的不停电改造施工,希望为变电站改造提供借鉴。
The safe and stable operation of 220kV substation is related to the stability of the whole power grid,and the time of substation blackout is also restricted more strictly.Combining with the practice of DC system transformation,this paper takes 220kV Wali DC system transformation as an example to discuss the blackout reconstruction construction of conventional substation DC system for the future.The experience of substation transformation is provided.
