继电保护装置采样回路负载效应研究

Study on Load Effect of Sampling Loop of Relay Protection Device

针对继电保护装置采样回路的负载效应问题,首先对保护装置常规采样回路进行简要介绍,然后介绍了负载效应问题及影响,并对负载效应影响进行了仿真计算,最后提出了可减弱采样负载效应的设计方法。

Aiming at the load effect problem of the sampling circuit of the relay protection device,the conventional sampling loop of the protection device is briefly introduced.Then,the load effect problem and its impact are introduced,and the load effect is simulated and calculated.Finally,a design method is proposed to reduce the sampling loading effect.
