摘要：The energy in the flowing water can be used to produce electricity. Hydro power is one of the best,cheapest, and cleanest sources of energy. New environmental laws affected by the danger of global warming have madeenergy from small hydropower plants more relevant. The mathematical theory of reliability has grown out of thedemands of modern technology and particularly out of experiences in World War II (1939-1945) with complex militarysystems although the concept of reliability is as old as man himself. In the present paper we have taken two-nonidenticalwarm standby system with failure time distribution as exponential and repair time distribution as general. TheRole of voltage fluctuations and non-availability of water resulting failure of hydroelectric power under which thesystem operates plays significant role on its working. We are considering system under (i) voltage fluctuations and (ii)Non-availability of water resulting failure of hydroelectric power causing different types of failure requiring differenttypes of repair facilities. Using semi Markov regenerative point technique we have calculated different reliabilitycharacteristics such as MTSF, reliability of the system, availability analysis in steady state, busy period analysis of thesystem under repair, expected number of visits by the repairman in the long run and gain-function and graphs aredrawn.
