基于输电线路布局优化的管道过电压防护
Pipeline Overvoltage Protection Based on Optimization of Transmission Line Layout
摘要
Abstract
After a single phase-to-ground fault occurs on a transmission line,the adjacent buried oil and gas pipelines suffer a significant electromagnetic induced voltage.Aiming at the above problems,the influence of transmission line parameters on electromagnetic interference of buried pipelines is studied.The simulation models of transmission line and buried pipeline are established in CDEGS simulation soft-ware.The influence of factors such as tower grounding model,height of phase and ground lines,fault current,fault location,parallel distance between transmission line and buried pipeline,and grounding mode of overhead ground wire on pipeline coating induced voltage is studied in detail.According to a large number of simulations,the following characteristics are summarized.The induced voltage of pipe-line coating effectively decreases with the increase of parallel distance between transmission lines and bur-ied pipelines.The conclusions are useful for the design of transmission lines and the safety protection of buried pipelines.关键词
