基于G1赋权法的配电网带电作业安全综合评估

Comprehensive Evaluation for Live Working Safety in Distribution Network Based on G1 Weighting Method

摘要:

随着城市配电网可靠性要求越来越高,全国各大城市配电网带电作业急速扩张,其作业的安全综合评估显得十分重要。配电网带电作业的安全受到城市电配电网实际运行环境、安全生产制度以及作业人员综合素质等多方面因素的影响,使其呈现出分层分级的非线性综合评价的特征。为此,提出采用一种无需进行一致性检验的G1赋权法进行综合评估的思路。首先,通过深入分析带电作业特点,建立起配电网带电作业安全综合评价指标体系;然后,利用G1赋权法确定各指标因素的各自权重,计算得到综合评价结果;最后,通过对某实际带电作业现场的安全性进行评估验证,说明所提方法的合理性与有效性,可为带电作业现场安全管理提供参考。

Abstract:

As the reliability requirements of urban distribution network are getting higher and higher，the live working of distribution network in major cities across the country is rapidly expanding，and comprehensive evaluation for the safety of live working is very important． The safety of live working in distribution network is affected by many factors，such as the actual operating environment of urban distribution network，the safety production system and the comprehensive quality of the operators， which makes it appear as a hierarchical and non － linear comprehensive evaluation． To this end，a comprehensive evaluation method using G1 weighting method that does not require consistency check is proposed． Through in － depth analysis of the characteristics of live working，a comprehensive evaluation index system for the safety of live working in distribution network is established，and then G1 weighting method is used to determine the respective weights of each index factor，and at last the comprehensive evaluation results are obtained by calculation． Finally，the evaluation and verification for the safety of an actual live working site demonstrates the rationality and effectiveness of the proposed method，which can provide a reference for the safety management of live working sites．
