| Abstract: | 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. |
