摘要(Abstract):
电流互感器饱和问题一直是影响保护正确动作的关键问题,所以需要对电流互感器饱和情况进行深入的研究,分析二次电流波形。同时,电流互感器的二次侧负荷也影响着互感器的饱和,针对二次侧不同的负载,对电流互感器的稳态饱和与暂态饱和做出理论分析和仿真。
The saturation of CT has great influence on the performance of the protection.To ensure the relaying protections operating correctly under transient saturation circumstance,we should make deep research on the saturation craracteristics of CT and analyze the saturated current shape.At the same time different type loads having effect on the saturation characteristics of current transˉformer,we analyze and simulate the saturation characteristics of current transformer based on differˉent type load in this paper.
