摘要
以2010年全国火电大机组竞赛运行数据为样本集,根据投影寻踪原理并结合遗传算法优化,建立了超临界600MW火电机组可靠性等级评价模型,并对模型等级评价结果与竞赛结果进行了对比.结果表明:基于投影寻踪原理的机组可靠性等级评价结果与机组竞赛发布结果基本一致.所建模型规避了人为决定权重的缺点,客观性较强、准确有效、应用简便且可操作性强.
Taking the competition data of domestic large thermal power plants in 2010 as a sample set, a model for reliability evaluation of 600 MW supercritical power units was built up based on projection pursuit principle and genetic algorithm, with which a comparison was made between the evaluation results and relevant competition data. Results show that the evaluation results based on the newly built model agree well with the competition data. Overcoming the deficiency of artificial factors, the model has features of strong objectivity, high precision, great effectiveness and facile operation.
