为克服传统配电网运检过程中面临的复杂性和大规模性的局限,结合信息矫正与Boltzmann思想提出了一种故障定位模型,并开展了仿真分析和实际应用验证.结果表明,信息矫正与Boltzmann思想的引入使处理单个故障节点时定位时间基本在 2s以内,迭代次数低于 40 次.在处理多故障多畸变情况时,所提出的模型优于对比算法,平均定位时间为 2.45 s.在大规模配电网运检实际应用中,模型在 15 天内检测出 365 个故障,正确率达到 92.33%且无漏检.该模型在故障检测效率方面表现出色,定位误差也保持在 5 m以内.
Information Correction and Boltzmann Approach-based Fault Localization Model for Operational Inspection of Distribution Networks
In order to overcome the limitations of complexity and large scale in the conventional operational inspection process of distribution networks,a fault localization model was proposed by combining information correction and Boltz-mann approach,and verification was carried out through simulative analysis and practical application.The results show that the localization time cost for a single fault node is mostly less than 2 s with the number of iterations less than 40.In multi-fault and multi-distortion cases,the proposed model is superior to the selected reference algorithm with an average localization time cost of 2.45 s.In the practical application of large-scale distribution network operational inspection,the model can detect 365 faults within 15 days with a correction rate of 92.33%no missed detection.The model performs well in terms of fault detection efficiency and maintains a localization deviation of less than 5 m.
