±800 kV换流站GIS工频耐压试验仿真分析

Simulation of Power Frequency GIS Test in ±800 kV Converter Station

针对锡盟±800 kV换流站所处环境的特殊性,提出了1种增加并联谐振电抗以提高试验设备带载能力的GIS工频耐压现场试验的优化方案。通过仿真计算回路等效电阻与补偿电抗器串间互感,并与历次特高压GIS工频耐压现场试验的实际数据进行对比分析,结果表明优化方案可行。

In view of the particularity of the environment in the Ximeng±800 kV converter station,one kind of optimization schemes were proposed to improve the load capacity of the test equipment by increasing parallel resonant reactance.The equivalent resistance of the circuit was calculated and the mutual inductance between the compensating reactor series was calculated by simulation,and the actual data of the field test of the extra high voltage GIS were compared with the actual data of the field tests.The results showed that the optimization scheme was feasible.
