500kV同塔双回输电线路下平行排列油气管道上的感应电压和感应电流仿真分析OA北大核心CSCDCSTPCD
Simulation analysis for Induced Voltage and Induced Current in the Oil & Gas Pipeline Parallel Under 500 kV AC Double-circuit Transmission Lines on Same Tower
高压输电线路下方存在平行油气管道,静电感应和电磁耦合产生的感应电压和感应电流会加速管道的腐蚀.文中利用ATP/EMTP仿真软件建立了同塔双回输电线路模型和输油管道的仿真模型,考虑了线路运行电流大小、平行管道长度、土壤电阻率大小、杆塔呼称高度以及管道偏离杆塔中心线距离等因素对感应电压、感应电流分量的影响.研究结果表明:油气管道上的静电感应分量主要受平行金属管道长度、杆塔呼高度和管道偏离杆塔中心线距离的影响;管道上的电磁感应分量主要受运行电流的大小、…查看全部>>
