Performance and FMECA of a wind turbine based on SCADA and lidar data

Abstract

<p>This paper presents an approach to identify risks for different failures that could affect wind turbine performance, and reduce the measured annual electrical production (MAEP). The proposed approach is based on FMECA (failure mode, effects and criticality analysis) and wind turbine performance study. We present firstly the methodology of performance calculation based on IEC 61400 standard, then we identify the energy gap between the MAEP and WAEP for the case study, we present an extended and reviewed FMECA, by introducing definition of factors related to environment, health and security. As a result we present an actions plan for similar failures deduced from wind performance study and risk-based FMECA, in order to reduce failure risks and optimize production by consequence. The case study is a 2.3 MW onshore wind turbine, different data that are used in this paper were collected from SCADA and lidar.</p>

Comparison between horizontal and vertical axis wind turbine

“…Among the most important renewable energy sources are the sun and wind, and the aspiration to increase energy production through them in the future is something that has actually been implemented [14]. Industry of wind turbine become looking to reduce production and maintenance costs [15]. Horizontal wind turbines are the oldest among their types and their advantages are that the torque is high, which makes them suitable for rotating water pumps.…”

Development and analysis of VAWT offgrid in ducting system

“…Wind energy is of the best renewable energy due to cost reduction of wind power generation, improvement of the used technology and equipment reliability [11]. Two types of the most popular wind turbines are Fixed Speed Wind Turbine (FSWT) and Variable Speed Wind Turbine (VSWT) [12].…”
