|
摘要
为了正确评价离子接地深井降阻措施的降阻效果,并用以指导设计,需要对离子接地深井进行正确模拟。基于CDEGS软件,提出了一种工程上较为合理的离子接地深井模型模拟方法,并结合一个工程实际应用,通过现场测试与仿真结果验证了该模拟方法的可行性,解决了离子接地深井的合理模拟问题,对接地网设计阶段的安全性分析起到了进一步完善的作用。
In high soil resistivity region,resistance reducing measure of ion grounding deep well is gradually applied in resistance reducing engineering of substation grounding grid.For correctly estimate resistance reducing effect and guiding specific design,it is required to carry on correct simulation on ion grounding deep well.Based on CDEGS software,this paper proposes a kind of reasonable simulation method of ion grounding deep well model.Combining with a practical engineering application and by field testing and simulating results,it verifies feasibility of this method which is able to solve reasonable simulation problem of ion grounding deep well and play a further complete role in analyzing safety of grounding grid design stage.
