Study on the Application of a New Magnetic Controlled Arc Suppression Coil in Power Distribution System

介绍了一种新型磁控消弧线圈,并根据配网运行特点,对磁控消弧线圈进行了参数设置,构建了ATP-EMTP仿真模型,对其谐波特性及抑制PT谐振效果进行了仿真。仿真结果表明通过两种极限饱和状态,在降低谐波含量的同时,既可以有效的熄灭接地电弧,又可以很好地抑制PT谐振现象。

This paper introduces a new type of magnetic controlled arc suppression coil. It sets parameters of magnetic controlled arc suppression coil,constructs an ATP-EMTP simulation model according to the operation characteristics of distribution network,and simulates harmonic characteristics and saturation effect of suppression of PT resonance. The simulation results illustrate that through two limited saturated states,the new magnetic controlled arc suppression coil can reduce harmonic contents,at the same time it can effectively extinguish the arc,and can effectively inhibit PT resonance saturation phenomenon.
