Condition assessment of fossil-fired power plant based on fuzzy comprehensive evaluation
Zhongguang Fu · Proceedings of the CSEE · 2009
Fuzzy comprehensive evaluation(FCE) is introduced into condition assessment of fossil-fired power plant,the entire state of the five units of 600 MW in five plants were comprehensively assessed.The representative set of fuzzy evaluation,primary factors set and subsidiary factors set were selected and a complete model was established.The process of modeling was analyzed and studied,as follows:selecting of factors set,layout hierarchy of index,selecting of sub function and the method of determining factors of fuzzy sets.Through collection of all index assessment,comparison could be made among different units in the same condition and sets of preferable compositive characteristics could be distinctly estimated.The results could be used not only to assess the completion of varieties of set indexes,but also to keep competition among units.
