Abstract

Wind is a clean source of electricity as it doesn't produce harm to environment. But the output obtained from wind resource is uncertain. Power output from the wind electric conversion system is variable. Hence the main objective of this project is to develop a method to evaluate the reliability of output power obtained from wind electric conversion system The approach used here involves the simplified reliability model for the wind energy conversion system.

In this methodology, four factors are calculated which are wind availability factor, constant power output factor, variable power output factor, factors for mechanical failure. In order to calculate these factors turbine design parameters such as shape factor (β), which is dependent on the height of the tower and station, Scale factor (α), which is nearer to the average wind speed are considered. These parameters are determined using weibull distribution. For the reliability evaluation, plants considered in this project are Jajikalgudda, Kappatagudda, Seegegudda, and Chitradurga The procedure centers on the determination of Forced outage rate. Sensitivity graphs for the several key parameters are plotted in MATLAB.
