Evaluating Wind Turbine Power Plant Reliability Through Fault Tree Analysis

This study presents the application of the Fault Tree Analysis (FTA) method in analyzing the reliability of a wind turbine power plant. Examining all crucial system components and simulating potential failure probabilities demonstrated the system's overall reliability using two different coefficient simulations. This approach aims to identify which elements have the most significant impact on the reliability of wind turbine systems and, consequently, determine the critical points of the analyzed system. The displayed fault tree and appropriate tabular analysis present comparative analyses between these two simulations. From both case examples, it can be concluded that the system's generator plays a crucial role in influencing the overall reliability. By applying Boolean algebra and input coefficients for two cases, the values of potential wind turbine failures were obtained: in the first case, 11.7%, while in the second case, the percentage is 5.7%.
