董家口-平度管道交流干扰模拟计算及效果评价

Simulation Calculation and Mitigation Evaluation of AC Interence on Shandong LNG Pipeline

通过现场调研管道沿线高压交流输电线路的分布和运行情况,结合杂散电流干扰现场检测评价、开展输电线路稳态条件下的模拟分析及排流措施模拟设计,制定干扰缓解措施,并跟踪完成现场排流缓解措施的效果评价。确保管道排流缓解效果满足现行标准中相关的安全和腐蚀限值要求。

Through field investigation of the distribution of AC interference sources along the pipeline,combined with field detection and evaluation of stray current interference,simulation analysis under steady-state condition of transmission lines and interference mitigation measures were formulated,The effect evaluation was tracked,to ensure that the relief effect of pipeline drainage meets the relevant safety and corrosion limit requirements in the current standards.
