摘要

针对高压隔离开关分合闸不到位的问题

文中提出了一种基于方向梯度直方图（HOG）和支持向量机（SVM）的隔离开关异常状态搜索识别算法

通过试验验证了该方法用于搜索识别变电站内高压隔离开关的可行性

文中首次提出了"分合闸到位判定角"的概念

并将"分合闸到位判定角"用于判断高压隔离开关分合闸的到位情况。最后对变电站内4种常见型号的高压隔离开关进行了分合闸状态实验验证

实验结果表明

该算法能够准确地识别出分合闸不到位的高压隔离开关图像

文中的研究成果为提高高压隔离开关运行可靠性提供了新的思路。

Abstract

For the problem of incomplete switch on and off of high-voltage disconnector we propose an abnormal state search recognition algorithm based on the direction gradient histogram（HOG） and the support vector machine（SVM） in this paper.This method has been verified by experiment in the substation high-voltage disconnector.The concept "complete opening determine angle" and "complete closing determine angle" are proposed first time to judge the on-off state of high-voltage disconnector.Finally

switching on-off experiment on four common types of highvoltage disconnector has been conducted.The experiment results show that the algorithm can accurately identify images of the switches which did not reach the designated position.This research provides a new thought of improving the operation reliability of high-voltage disconnector.
