雷击高压输电线路对邻近输气管道的电磁影响
|
摘要
为研究雷击高压输电线路对邻近输气管道的电磁干扰问题,以220kV同塔双回输电线路下方并行输气管道为例,利用电磁暂态仿真软件ATP建立包含输电线路、杆塔、绝缘子、输气管道及其防护层的等效时域模型。综合考虑了雷击位置、雷电流幅值、水平间距、土壤电阻率、呼称高度、管径等因素对高压输电线路附近输气管道交流干扰的影响。结果表明:输气管道的交流干扰受落雷点的影响较大;交流干扰与管道偏离杆塔中心距成正比;土壤电阻率、管道管径、呼称高度等因素对管道的交流干扰较小。得出的结论可以为高压线路附近输气管道的敷设提供理论指导,具有一定的工程价值。
Using the case of 220kV double circuit transmission line on the same tower,a time domain simulation cal-culation model comprising the transmission line parameters,types of tower,insulator,gas pipeline and its protectivelayer is establishedby the electromagnetic transient simulation software ATP,which is used to analyze the effects oflightning location,mine current size,the horizontal spacing,the soil resistivity,the tower height and diameter of pipefor the interference of the gas transmission pipeline in the vicinity of the high voltage transmission line.The resultsshow that:AC interference of gas pipeline is strongly influenced by lightning point;AC interference is proportional tothe distance between pipeline and Tower Center,while the effects of the soil resistivity,pipeline diameter and thetower height are small. The conclusion provides theoretical guidance for the laying of gas pipeline in the vicinity of the high voltage line,so it has a certain engineering value.
