| 摘 要： | 为了分析发电机的局放严重程度,针对局放的二维相位分布图谱,文中构造了局放的Sk-Ku图谱,并通过两个具体的发电机实例进行了对比分析。分析结果表明,Sk-Ku图谱能有效地表征出局放的严重程度,不同发电机局放严重程度之间具有一定的可比性。局部放电量和放电次数的Sk-Ku图谱均呈现二次曲线的性状,随着局放严重程度的增加,图谱整体有从1、2象限向3、4象限移动的趋势,数据的变化范围出现大幅度的减小。

| Abstract: | For evaluating the partial discharge extent of generator,as far as the two dimensional phase resolved plots were concerned,a new type of plot,namely Sk-Ku plot,was constructed.Furthermore,the Sk-Ku plot was put into the cross analysis of partial discharge detected from two practical generators.The results analysis demonstrate that,Sk-Ku plot can effectively reflect the partial discharge extent and partial discharge derived from different generators can be compared to some extent.Sk-Ku plots of discharge magnitude and count take on the character of conic,what is more,with the increase of partial discharge,the Sk-Ku plots show the trend of shifting from 1,2 quadrants to 3,4 quadrants.In addition,the distribution range of the data decreases significantly. |
