摘要
阐述了短期可靠性评估中等效机组的概念及状态概率的求解方法,并把这一思想和方法应用于互联电力系统短期可靠性评估,建立了等效支援教学模型,且能方便地与子系统模型结合。模型和算法不仅解决了互联电力系统短期可靠性评估中“状态组合爆炸”的难题,而且提高了计算精度。通过算例计算表明:模型和算法是可行和有效的。
This paper presents the concept of equivalent-unit and the solution method of state probabilities for short-term reliability evaluation for generation systems. The ideas and methods
are applied to evaluate short-term reliability of intercommected power systems,and the models of equivalent assistance,which can be conveniently combined with subsystem models,are propesed. The models and algorithm proposed not only solve the difficult problem of 'state explosion' , but also improve the calculating accuracy. A numerical example is given to show that the models and algorithm are feasible and effective.
