一种基于混合型柔性消弧的实时对地参数测量方法
Real⁃time Parameter Measurement Method Against Ground Based on Hybrid Flexible Arc Suppression
摘要
Abstract
The existing single⁃phase grounding current suppression devices for distribution network need measur⁃ing ground parameters during normal operation and injecting current to achieve full⁃compensation arc suppression upon fault occurrence.However,since the three⁃phase parameters change against ground with the operation mode of the distribution mode,the current arc suppression device may fail to compensate the system's ground parameters back to normal levels due to the parameter changes after a single⁃phase grounding fault.Consequently,it cannot achieve full⁃compensation arc suppression.To address above issues,in this paper a real⁃time measurement method of ground parameters based on hybrid flexible arc suppression is proposed.After detecting the single⁃phase ground⁃ing fault of distribution network,the active current suppression device is used to inject characteristic frequency cur⁃rent signals,calculate the system transition resistance and total capacitance to ground,and calculate the current to be injected.Then,the non⁃power electronic equipment is closed,the power electronic equipment and the non⁃power electronic equipment are connected in parallel,and the current value that the current source needs to be injected is calculated to achieve the fault arc suppression.The simulation results of MATLAB and the experimental results of true type test site prove that the proposed scheme can accurately measure the ground parameter of distribution net⁃work in real time under different fault scenarios and achieve safe and reliable arc suppression.关键词
