| 中文摘要: |
| 基于特高频的局部放电定位技术近年来受到广泛关注,而由于变电站环境复杂,噪声干扰信号较多,导致对同一放电源的定位结果波动性较大,定位不够准确。提出了基于K-Means的测量值去抖算法,通过对多次测量结果进行综合考量来确定最优的测量值,实验结果表明,能够大大降低定位测量结果的抖动性,且提高了定位精度,具有工程可行性。 |
| 英文摘要: |
| UHF-based partial discharge location technology has received wide spread attention in recent years. However, complex substation environment and much noise interference signal have led to big fluctuation of locating results for the same discharging source and to insufficient location accuracy. In this paper, we propose a K-Means-based de-bouncing algorithm to determine optimal measured value through comprehensive considerations of the results of multiple measurements. Experimental results show that the proposed algorithm can greatly reduce the bouncing of location measurement results and raise location accuracy, and that it has engineering feasibility. |
