PREVENTIVE MAINTENANCE POLICY FOR HYDRO POWER PLANTS USING FUZZY, SET THEORY

Abstract

In countries like India, there is a huge gap between the electricity generation and demand. To meet this demand a bulk investment is needed to install new generating plants immediately. Our country's economy does not permit such a bulk investment immediately. Even if funds are arranged, it will take a quite long gestation period to realize the benefits. Hence, besides installing new generating stations it is needed to enhance the efficiency of the already installed power generating stations. One way to increase the efficiency is adopting a proper preventive maintenance policy for optimising the generations. This study is intended to produce a simple yet realistic process for evaluation of an effective preventive maintenance policy, which yields optimal energy generation. To attain this objective, an opportunistic preventive maintenance model is incorporated which resembles the practical situation. This maintenance model is realized by Monte Carlo simulation method to find the impact of preventive maintenance on productivity of hydro generating plants....
