A reliability growth model for 300 MW pumped-storage power units

A reliability growth model for pumped-storage power units is presented. Ways for estimating and fitting on checking the model’s parameters are given together with analysis results concerning the reliability growth of 300MW pumped-storage power units. On site operation, reliability data show that the reliability growth model conforms to rules of reliability growth tendency. Analysisresults of reliability growth indicate that measures taken for improving maintenance and operation by the pumpedstorage power companies are effective and that the reliability of the 300MW pumped-storage power units exhibits a rising tendency.
