换流站内深井接地极影响因素研究

Study on the Influence Factors of Grounding Electrode in Deep Well of Converter Station

对换流站内深井接地极开展建模仿真,研究深井接地极的长度和焦炭的厚度对其电气性能的影响,得出了站内深井接地极长度≤500m和焦炭床厚度应≤0.4m的主要结论.研究成果为换流站内深井接地极的建设应用提供了理论指导,实际意义显著.

The paper carries out modeling and simulation of deep well grounding electrode in the converter station, studies the influence of the length of deep well grounding pole and the thickness of coke on its electrical performance. The main conclusions are as follows： （1） the length ofdeep well groundingpole within the stationis less than 500m; （2） the thickness of coke bed should be less than 0.4m. The research results provide theoretical guidance for the construction and application of deep we 11 grounding poles in converter stations, has significance practical meaning.
