Özet:

In the modern societies, one of the most important indicators of the economical growth is the energy resources. The energy demand is increasing continuously due to the rapid population growth and industrialization and this demand can not be satisfied with the available limited resources. Consequently, the gap between the production and the consumption of the energy is growing rapidly. Thus, it is gaining much more importance to benefit from the renewable energy resources in a more effective manner. Failure Mode and Effects Analysis (FMEA) is a quality improvement technique that prevents the formation of a failure or that determines and resolves the failure types existing in a system and in the functions or the components of a system as early as possible. In this study, a risk analysis is done to improve, overcome and determine the risks in the solar, geothermal and wind power plants by using FMEA and Fuzzy FMEA techniques. In the study, the risks in wind, solar and geothermal power plants are classified according to the economical and financial, social and environmental, construction and management, political and technological aspects. By using FMEA and Fuzzy FMEA techniques, the risk priority numbers of power plants are calculated and a risk table is constructed. The three power plant types are rated according to the results obtained by using the two techniques and they are compared in terms of the risks that they produce.
