2019年度夏期间云田施工过渡方案比选
摘要
500 kV云田变是向长沙南部以及株洲北部电网供电的枢纽变电站。2018年
云田的500 kV变压器扩建及220 kV整站改造工程开工。云田改造过渡阶段
周边220 kV网架结构变化较大
影响了负荷中心的供电能力和稳定水平。通过对云田2019年度夏期间施工过渡方案进行优化调整
可以有效地限制220 kV短路电流
同时保障电网安全稳定运行和负荷供应。
Abstract
Yuntian substation is a key substation supplying power to southern part of Changsha and northern part of Zhuzhou. The reconstruction and extension project in Yuntian substation has been started since 2018. During the construction
the power grid structure changed a lot. Due to the incomplete power grid structure
the power supply capacity and stability level has been reduced. By optimizing the construction scheme
220 kV short-circuit current can be limited
power supply capacity and stability of power grid can be ensured in the same time.
