对GIS设置了四种典型缺陷, 用基于动态粒子群算法 ( DPSO) 优化的BP网络对其局放图谱进行识别, 能较高效率地判断出缺陷类型; 用灰度信息图像配准的方法对X射线数字图像进行处理, 可以直观地辨别缺陷形态和位置. 通过实验与应用得出, 先用局放图谱识别出缺陷类型, 再于可能出现故障位置进行X射线检测, 可显著提高诊断的准确度和效率, 并减少X射线单独检测因时间过长对工作人员的辐射伤害.
對GIS設置瞭四種典型缺陷, 用基于動態粒子群算法 ( DPSO) 優化的BP網絡對其跼放圖譜進行識彆, 能較高效率地判斷齣缺陷類型; 用灰度信息圖像配準的方法對X射線數字圖像進行處理, 可以直觀地辨彆缺陷形態和位置. 通過實驗與應用得齣, 先用跼放圖譜識彆齣缺陷類型, 再于可能齣現故障位置進行X射線檢測, 可顯著提高診斷的準確度和效率, 併減少X射線單獨檢測因時間過長對工作人員的輻射傷害.

In this paper, one method of DPSO optimized BP network has been applied to recognize partial discharge diagram of GIS four typical defects pre-set. It can judge the defects type more efficiently. X-ray testing technology, based on gray scale image reg-istration can visually identify defect type and location. Through the analysis of the experiment and application, identifying the defects type by partial discharge map firstly, and then testing by X-ray at the possible failure locations, can improve the diagnosis efficiency and accuracy significantly, and reduce the X-ray radiation damage to the staff because of detection alone using too much time.
