摘要
以云南-广东±800 k V输电线路为研究对象,利用COMSOL软件建立简化的二维输电线路仿真模型,对不同空气湿度下±800 k V输电线路的地面合成电场和离子流密度进行仿真研究,分析了空气湿度对地面合成电场与离子流密度的影响规律,验证其计算结果。结果表明:计算值与测量值的分布趋势基本保持一致,负极导线附近的合成场强吻合度比正极导线高。根据研究结果确定了计算模型的正确性。
The ground synthetic electric field and ion current density of Yunnan-Guangdong ±800 k V transmission lines under different air humidity were simulated by a simplified two-dimensional transmission line simulation model which was established using the COMSOL, and the effects of air humidity on the ground synthetic electric field and ionic current density were analyzed, the calculation results were verified. The results show that the distribution trends of the calculated value and the measured value are basically the same, the coincidence degree of combined field strength near the negative lead is better than that of the positive lead. The correctness of the calculation model is confirmed according to the study results.
