Research On Evaluation Method Of The Power Curve Of Wind Turbine Reliability Based On Performance

The rapid development of wind power industry has become an important force in the rapid development of new energy, greatly promoted the reformation of energy system. But the failure of the wind turbines and also with the increase of net increase wind turbines, performance evaluation of wind turbines has great significance for the operation and maintenance of wind turbines.Reliability is an important concept in wind turbine equipment, is a very important indicator of quality. Reliability Technology development today, by the calculation of the amount of reliability features, can be given a variety of quantitative evaluation. With these quantitative evaluation of the reliability of the feature quantity, so that wind turbines have a clear and consistent approach in terms of reliability assessment, evaluation provides a unified platform for wind turbine manufacturers and the use of the customer.Based on the actual operating data drawn power curve with bin method using output parameters of wind turbine reliability evaluation of its performance. Run the power curve which utilize wind turbine manufacturer promises power curve and the theoretical power curve, performance testing volume construction of wind turbines, by probability theory and mathematical statistics method to establish the reliability of the analysis based on the wind turbine output performance, by the actual plant data validation, the method can objectively valid for reliability and quality evaluation of the unit.
