摘要
采用统一接口系统的微电网可靠性问题较为特殊,需要单独建模。结合概率统计思想,将稳定性问题分为软件问题和硬件问题两大类,并提出了平均失效时间和最短失效时间的计算依据,根据电网结构的并联和串联规律进行有效失效时间的计算,进而评估整个微电网系统的可靠性,得出了基于概率统计和网络结构的针对微电网的可靠性建模方法。最终通过IEEE34节点测试系统进行计算,说明了该方法的计算流程。
The reliability research of the Micro-Grid including a unified interface needs a separating modeling. Considering the probability of statistical, the stability problem was divided into two major categories of software and hardware issues and made a mean time to failure and the shortest time to failure calculated on the basis of calculation of the effective time to failure according to the grid structure of the parallel and series laws of to assess the reliability of the whole micro-grid system, obtained for micro-grid reliability modeling methods based on probability and statistics, and network structure. Finally, the IEEE34 bus test system was calculated to illustrate that the method of calculation process.
