摘要
针对目前继电保护系统可靠性评估过程中由于缺乏基础数据积累和必要挖掘而影响了评估结果可信度的问题,从继电保护系统可靠性及其基础数据的特点入手,设计实现了可靠性基础数据分析软件。软件在对原始数据进行预处理的基础上从不同角度进行立体分析,实现了多种可靠性指标的统计计算、失效率函数与可靠度函数等的回归分析以及设备可靠度的短期预测功能。其分析结果可为全面评估继电保护系统的可靠性、制定合理的检修策略等提供依据,对进一步掌握和提升保护系统可靠运行水平具有积极意义。
To improve the credibility of protection reliability assessment results affected by the lack of basic data accumulation and mining, statistical analysis software of protection reliability basic data is designed and accomplished based on the characteristics of protection systems. Basic data is analyzed from different aspects. Statistical calculation, regression analysis of failure rate function and short-term forecast of device reliability are accomplished based on data preprocess. The analysis results could supply reference for assessing protection reliability and deciding reasonable maintenance strategy, and have positive effects on further promoting the reliability operating level of protection systems.
