摘要
利用数值模拟计算的方法研究了高压直流接地极对管道干扰规律,计算分析了接地极在不同运行工况、接地极-管道间距、土壤电阻率及管道接地前后对管道干扰影响规律,研究结论为干扰预测及缓解提供了理论依据。
The numerical simulation method is used to study the interference rule of HVDC grounding electrode to buried pipeline. Different operating conditions, grounding electrode-pipe spacing, soil resistivity and pipeline grounding is calculated and analyzed. The conclusions provide a theoretical basis to predicate pipeline interference and mitigation.
