基于MATLAB仿真的谐振接地系统单相接地故障分析
Single-Phase-to-ground Faulted Analysis for Resonant Grounded System Based on Simulation by MATLAB
我国中低压电网主要采用小电流接地系统，单相接地故障选线问题一直是谐振接地系统的一个重要研究课题。本文针对谐振接地系统，从理论上分析了发生单相接地故障时零序电压和零序电流的特征。采用MATLAB里面的电力系统仿真工具搭建了10KV谐振接地系统模型，通过仿真，对理论分析进行了验证，为选线算法的研究提供了理论依据。
Small current neutral grounding system is widely applied to medium and low voltage distribution networks in China, detecting the ground fault is an important research subject in resonance grounding system. In this paper, from the theoretical analysis of the zero sequence voltage and zero sequence current characteristics when single-phase ground fault occured for resonant grounding system.By SimPowersystems in MATLAB built 10KV resonant grounding system model, through simulation, theoretical analysis was validated, to provide a theoretical basis for grounding fault feeder detect ion algorithm.
