Analysis of Wind Turbine Power Oscillation Characteristics Based on the Equivalent Wind Speed
摘要
Abstract
Natural wind is stochastic, its speed and direction change randomly and frequently. Wind turbines often suffer from a series of engineering issues during operation, including frequent yaw, overlarge vibration and downtime because of the changes of wind and control strategies. In this paper, an equivalent wind speed model including wind shear, tower shadow effect and yaw error is established, and the Matlab code is used for simulation analysis. The results are compared with the actual operation data from a wind farm. The output power oscillation characteristics at the equivalent wind speed are studied. The results indicate that the components of the equivalent wind speed have significant influence on the output power characteristics of the wind turbine. These results may provide a theoretical support for optimizing the control strategies to increase the operation stability of the wind turbines and the utilization ratio of wind energy.关键词
