蒙东电网输变电可靠性非计划停运数据分析

Analysis on Power Transmission and Transformation Reliability Non-Planed Outages Data in East Inner Mongolia Electric Power Grid

以国网蒙东电力高压架空线路实际发生的非计划停运为例,分别以设施的停运类别、设施部位、责任原因及现场事故调查等多个维度,展开了对66 kV及以上输变电系统非计划停运设施的可靠性分析、评价及相应的应对策略,并给出了针对性的改进措施,不仅为电力可靠性人员在数据分析方面提供一套适用于当前输变电设施发生非计划停运的可靠性评价分析方法,同时也给其它电力部门在对事故分析和处理方面提供了参考。

Taking non-planed outages happening in practical high-tension overhead line of east inner Mongolia electric power grid for example,this paper carried out the reliability analysis,reliability evaluation and corresponding response strategies of non-planed outages equipments in 66 kV and above voltage level transmission system from multiple dimensions such as outages category,parts of equipment,power outage liability causes and field investment on accident of equipments etc,and gave the specific improvement measures,not only providing a sort of reliability evaluation and analysis ways suitable for the current non-planed outages happening in transmission equipments for electrical reliability personnel on data analysis,but also providing references on the analysis and processing of accidents for other electricity sectors.
