摘要：
Two levels of test point offset are simulated in PSCAD for the fully-measurable branch and their fault diagnosis results are compared to analyze the influence of test point offset on the corrosion diagnosis of grounding grid, based on which, a reducing method is proposed for different levels of test point offset. According to the proposed method, the mathematical model of non-linear fault diagnosis and the hybrid particle swarm algorithm are improved. The simulative results show that the improved grounding grid corrosion diagnosis algorithm is correct and effective in the condition of offset test point. © 2016, Electric Power Automation Equipment Press.
