摘要:

运用 ANSYS Maxwell 和 EMTP 软件联合仿真，将“场”和“路”相结合的方法用于计算 500 kV MOA 带电测量相 间干扰问题，并通过实际运行数据加以验证，为 MOA 在线监测减小相间干扰提供了理论依据和切实可行的办法。

Abstract:

A method combined with " field" and " circuit" is proposed to calculate the interphase interference during live line measurement of 500 kV metal oxide arrester ( MOA) ，which is verified by the joint simulation with ANSYS Maxwell and EMTP． And it provides theoretical basis and practical way to reduce interference effects．
