基于ATP-EMTP对配电网雷击过电压的仿真研究
Simulation Study on Lightning Overvoltage of Distribution Network Based on ATP-EMTP
摘要
Abstract
This paper states lightning current model,calculation model of each element of the distribution network and flash-over mechanism of insulator chain. By using electromagnetic transient simulation software ATP-EMTP,simulating calcula-tion model was established,impact on lightning resistant level of the line by impulse grounding resistance of the tower was compared and analyzed and improvement effectiveness of different installation schemes of line arresters on lightning resistant level were compared and analyzed,too. Simulating calculation result indicated that lightning overvoltage was likely to result in insulator flashover,but by installing line arresters and reducing grounding resistance of the tower,it was able to effective-ly improve lightning resistant level of 1 0 kV distribution lines and overvoltage endurance capacity of lines.关键词
