摘要
局部放电如果不能及时被发现并处理,很容易导致开关柜故障,甚至引发安全事故。为此,研究一种带电作业下10 kV配网开关柜局部放电自动定位方法。在10 kV配网开关柜上布设传感器,采集发生局部放电时的超声波信号并针对信号实施去噪处理,提高信号质量。将局部放电定位问题转换为全局目标优化问题,利用金豺优化算法求取满足目标函数最小值的最优解。结果表明:所研究方法定位出的局部放电坐标位置与实际位置更为接近,说明误差更小,定位结果更为准确。
If partial discharge cannot be detected and dealt with in a timely manner,it is easy to cause switchgear failures and e-ven safety accidents.To this end,a method for automatic positioning of partial discharge in 10kV distribution network switchgear un-der live working conditions is studied.Install sensors on the 10kV distribution network switchgear to collect ultrasonic signals during partial discharge and implement denoising processing to improve signal quality.Transform the partial discharge localization problem into a global objective optimization problem,and use the Golden Jackal Optimization Algorithm to obtain the optimal solution that sat-isfies the minimum value of the objective function.The results indicate that the partial discharge coordinate position determined by the research method is closer to the actual position,indicating a smaller error and more accurate positioning results.
