摘要
高铁采用交流供电,运行中其供电系统会对临近的埋地管道造成交流干扰,加速管道腐蚀,因此需要对交流干扰影响的管道进行缓解。本文运用数值模拟方法,对与高铁交叉并行的某管道进行交流干扰预测,研究了机车位置对干扰的影响,并进行了缓解方案的设计,形成了一套高铁交流干扰的缓解流程。研究得出:机车位于管道与高铁交叉点时,管道交流电流密度超出干扰评价指标,缓解方案设计为固态去耦合器加接地的方式,多次计算确定锌带敷设位置及数量,施加缓解方案后管道干扰达标,缓解效果经验证达到效果。
The high-speed railway adopts AC power supply,and its power supply system will cause AC interference to the nearby buried pipelines and accelerate pipeline corrosion during operation,so it is necessary to mitigate the pipeline affected by AC interference.In this paper,the numerical simulation method is used to predict the AC interference of a pipeline crossing and parallel with high-speed rail,and the influence of locomotive position on the interference is studied,and the mitigation scheme is designed,forming a set of AC interference mitigation flow of high-speed rail.The research results show that the AC current density of the pipeline exceeds the interference evaluation index when the locomotive is located at the intersection of the pipeline and the high-speed railway.The mitigation scheme is designed as a solid state de-coupler and grounding method.The position and quantity of zinc strip laying are calculated for many times.After applying the mitigation scheme,the pipeline interference reaches the standard,and the mitigation effect is verifi ed to be effective.
