摘要
该文建立了配电系统区间可靠性分析模型,首次提出大规模配电系统区间可靠性分析方法,用于解决配电系统可靠性参数和负荷参数存在不确知因素时的可靠性评估。详细描述了系统区间可靠性指标及其区间算法。开发了基于数据库的配电系统区间可靠性评估软件 DSIR2002,通过 50 节点典型配电系统和大规模实际系统计算验证了算法和软件的正确性和高效性。区间可靠性评估算法同时亦为一种更迅捷、优越的灵敏度分析工具。
Interval reliability models of Markov systems and a novel interval-analysis-based reliability evaluation method for large-scale distribution systems are presented Deconvolution formulas of interval arithmetic are deduced and applied in order to obtain sharp bounds of the results o reliability studies. Particularly, this paper advances detailed description of interval reliability evaluation algorithm unde interval uncertainty and ambiguity of component reliability parameters and load data. A software package DSIR2002 (Interval analysis based Distribution System Reliability evalua tion software) has been developed. Extensive investigation on IEEE RBTS test system, a 50-bus typical distribution system and a 573-bus distribution system have shown that the developed software is valid and effective. Capable of dealing with single variation as well as simultaneous variations o parameters, the interval reliability evaluation approach also serves as, in an unprecedented flexible manner, a fast and easy to-use sensitivity analysis tool.
