Reliability Assessment Of Adama I Wind Power Plant

Abstract

The importance of renewable energy sources has increased rapidly due to run out of fossil fuels and environmental effects of conventional energy production systems. As one of the renewable energy sources, wind energy has considered to be a leading alternative energy source by reason of vast energy potential of wind. Reliability analysis of wind turbine can help to identify, classify, and investigate several issues and concepts that arise in wind energy systems. Due to random characteristics of wind speed, electric generation reliability of wind energy system is affected in grid connected configurations. Reliability is critical to the design, operation, maintenance, and performance assessment and improvement of wind turbines (WTs). There are a wide variety of wind turbines types. The selection of a wind turbine type, the site of wind turbines fields erection and the maintenance scheme are basic parameters which should be carefully considered for optimum performance and reliable operation and power output. Many techniques had been developed and refined to represent and study the wind turbines complex system in order to make their operation safe, reliable and maintainable. The plant was produce power in good progress in the year 2014 and 2015 G.C. when comparing with year 2017 to 2019. In 2017 the production of the power plant goes down which shows the performance is not good. The objective of this thesis is to analyze and provide reliability information of Adama 1 WPP performance by considering the characteristics of wind at the site, operation of the components and others factors affecting the production of turbines. Wind speed data and failure data are analyzed by using mat lab software. Any data of turbines are collected by excel and fed to mat lab for performance assessment. Additionally, an extensive analysis of historical failure and downtime data of 34 turbines is presented. Quantitative and qualitative terms and measures are employed in order to analyze the reliability of wind turbines in Adama 1 wind farm. Plant Factor and availability are calculated. Finally, it is recommended that the company (EEP) could make ready wind turbine spare parts in stoke to reduce failure downtimes of the components.
