摘要:
高压开关柜作为配电网络中应用最广泛、使用数量最多的配电设备之一,为保证高压开关柜稳定运行及电网安全,需要对其状态进行准确评估。文中提出了一种综合赋权与加权秩和比(WRSR)相结合的新的开关柜状态评估方法。首先根据高压开关柜的绝缘状态、电气状态、机械状态和历史记录等信息,建立状态评估体系,运用层次分析法和熵权法相结合分别计算指标主客观权重并实现综合赋权;其次建立基于加权秩和比(WRSR)的开关柜状态评估模型,该模型构建简便,且具有强大的信息统计分析功能,可以实现状态分类及定量评估;最后运用该评估方法进行了实例分析,同时实现对多个开关柜的状态评估,并根据评估结果对多个开关柜的状态进行排序,进而制定相应的检修策略,有效地提高了检修效率。
Abstract:
A new method for evaluating the state of high-voltage switchgear is proposed, which combines the comprehensive weighting with the weighted rank sum ratio (WRSR). First, according to high-voltage switchgear’s insulation state, electrical state, mechanical state, historical records, and other information, a state evaluation system established. Second, the AHP and the entropy method are used to calculate the weights of the subjective and objective indexes, and the indexes are weighted comprehensively. Third, the weighted rank sum ratio (WRSR) method is employed to establish a state evaluation model of switchgear. The construction of this model is simple, and it has strong function of statistical information analysis for state classification and quantitative evaluation. Case analysis is carried out by using this state evaluation method, where state evaluations of multiple switchgears are realized, and the evaluated states of the switchgears are sorted for make corresponding maintenance strategies so as to effectively improves the maintenance efficiency.
