A Review on: Study of Variable Parameters to Measure Reliability Dependency of Hydro Power Unit

Operational industries or Plant have involve various mechanical equipment which need to repair before or after failure of each individual component come under maintenance program to sustain the load and produces desirable output as expected during design calculation to setup plants. On recording and collecting operational data by their functional time period of individual machine component can be mathematically modeled by using various solutions technique to evaluate the reliability parameters and availability of system evaluated with certain time period of entire plants. Maintenance required time and economical support to overhauling of mechanical device on which reliability depend so that future prediction can be done on load variation, equipment availability and necessary scheduled and forced outage superimposed in plant within write time to accommodate power and production supply to be continued. Maintenance and operation of a hydro power plant is very complicated and the process to calculate and analyzing its compatibility and reliability is very important. The availability and reliability of power plant can be evaluated by taking into account different failure parameter, namely failure rate (λ), repair rate (µ), MTTR, MTTF, MTBF. Reliable and durable operation of any power plant or system depends upon maintenance. The error in any a single sub unit can affect the annual performance and efficiency of power generation. Proper selection of reliability model and various failure parameter help to decrease repair cost, identifying sensitive equipment’s to be replaced and probable errors can be removed that improve availability of power at low cost as per given input, and allow a fair step towards energy independence of local community. Reliability model selection plays a key role in the cost-effectiveness of systems. Therefore the sole purpose of this study is intended to provide improved criteria for future proposal and serves as a basis for generation expansion planning of hydro power plants. Ultimately goal is to achieve desired output at optimized cost and time to the consumers.
