Analysis on Influence of Complex Power Transmission Environment on Main Equipment Safety of JiuAn Substation

In the complex power transmission environment, the electromagnetic characteristics of the 500kV JiuAn transformer substation node will change, which will make an important impact on the main equipment of substation. This paper makes in-depth study on the impact of complex power transmission environment on the main equipment, such as high voltage, long-term heavy load, changes of run mode and forced outage. On this basis, PSCAD Software is used to simulate this model, and the simulation result is analyzed. It is significant to ensure the security of main equipment of JiuAn substation.
