RELIABILITY EVALUATION OF WIND POWER PLANT ? A CASE STUDY

Rapid technological progress, combined with falling costs, a better understanding of financial risk and a growing appreciation of wider benefits, means that renewable energy is increasingly seen as the best solution. Today’s world needed uninterrupted qual itative electrical power with high reliability. Electrical energy that is derived from fossil fuels produces high pollution one side and on the other side electrical energy demand is co ntinuously increasing . To tackle this typical twin problem alternativ e resources such as wind, solar and bio mass energy sources are to be preferred. In order to reduce the utilization of fossil fuels that is to save the fossil fuel reserves {coal , diesel e.t.c} , it is very essential to see towards the above mention ed alte rnative sources. A R ealistic cost benefit analysis requires evaluation models that can recognize th e highly erratic nature of wind energy source and it’ s interdependence of random variables inherent in them . The proposed paper immensely narrate the pro babilistic reliability evaluation of wind power syst ems for gaining a better insight in system c o nstruction , operation and maintanance before they are built . The paper presents a case study of a Kakulakonda, Tirumala wind power plant with capacity 6MW for reliability assessment. The Reliability indices such as LOLE, LOEE , SAIFI, CAIFI, SAIDI, CAIDI e.t.c are evaluated and numerically analysed to check the s y stem performance.
