从潮流、暂态稳定、短路电流等方面，对湘潭电厂3号机组由500 kV电网改接至220 kV电网后，对主网及长株潭受端电网的影响进行系统分析。研究表明，这样改接可减轻云田主变下网压力，改善受端电网的潮流分布，同时系统的电压稳定水平较高，短路电流可维持在合理水平，技术上具有可行性。

The impact on the main network and the receiving end power grid of Changsha Zhuzhou Xiangtan area were systematically discussed in the paper, on the power flow,transient stability,short circuit current,after Xiangtan Power Plant 3rd unit has been grafted to 220 kV power network. The research result shows that after being reconnected,the heavy power flow of the Yuntian substation will be released, power flow distribution of receiving end power grid can be improved , and the stability and the short circuit current can be controlled in an reasonable range.
