电力物资质量对配网供电可靠性的影响分析

Influence Analysis of Electric Power Material Quality on Power Supply Reliability of Distribution Network

电力物资质量直接影响配电网安全可靠运行。针对目前电力企业物资质量存在的问题,提出了基于配电网供电可靠性的电力物资质量评估方案。首先,统计电力物资普遍存在的质量问题;其次,具体分析由于物资质量问题引起的配网故障形式;最后,采用实际配电线路算例分析物资质量对供电可靠性影响程度。所给出的电力物资品控建议有助于提升电力企业物资质量管控水平。

The quality of electric power material directly affects the security and reliability operation of distribution network.Aiming at existing problems of material quality in electric power enterprise,an assessment scheme for electric power material based on power supply reliability of distribution network is proposed.Firstly,the common problems in power material quality are counted up.Secondly,fault modes of distribution network caused by material quality problems are analyzed concretely.Finally,the degree of the influence of material quality on power supply reliability is analyzed by using examples of actual distribution lines.Suggestions on the quality control of power material are proposed which are helpful to the improvement of material quality control level of electric power enterprises.
