摘要
针对不同X/R比的线路进行了零序补偿系数的动态分析。绘制了动态渐变坡面,归纳了零序补偿系数变化规律,并通过现场实验验证了不同X/R比对零序补偿的影响。
In this paper, dynamic analysis on zerosequence compensating coefficient was conducted based on lines with different X/R ratios. Dynamic gradual change slope surface was illustrated. Moreover, the changing law of the zerosequence compensating coefficient was highlighted and inducted. A practical test verifies the impact on zero-sequence compensation by different X/R ratios.
