摘要
针对750 kV青南-西宁Ⅱ回线路与涩宁兰输气管道并行走廊的情况,在3种稳态状态下(未运行、正常运行、三相不平衡运行),计算走廊内输气管道受到的电磁影响。建立管道分布参数电路中固态去耦合器排流装置和绝缘法兰的等效电路模型,研究走廊内750 kV青南-西宁Ⅱ回线路投运后,各线路正常运行时的交流干扰缓解措施的粒子群优化问题。研究可为工程实践提供技术支持。
Against the situation of the 750 kV Qingnan-Xining Ⅱ power transmission line passed parallelly with Se-Ning-Lan Gas pipeline in the same passageway,the electromagnetic effect on the gas pipeline in the passageway under three steady operation conditions(out-service,service and service with three phases unbalance)is calculated,the equivalent circuit models for the solid state de-coupler discharge device and the insulation flange is built for the pipeline distribution parameters circuit,and the optimization of the particle group algorithm for AC interference relieve measure under the operation of the 750 kV Qingnan-Xining Ⅱ power transmission line is also studied in this paper.
