大型风电场的集中功率控制策略研究

Research on centralized power control strategies for large wind farms

在分析变速恒频风力发电机组与大型风力发电场控制系统关系的基础上,提出风力发电场的集中功率控制策略。利用M atlab/S imu link环境,建立风电场功率控制系统的仿真模型。以风扰动为例,对风力发电场并网的有功和无功功率调节过程进行仿真研究。理论研究和仿真分析结果验证了风电场集中功率控制策略的可行性和有效性。

Based on the analysis of the relationship between the variable speed constant frequency wind turbine and the large wind farm control system, the centralized power control strategy for wind farms is proposed. By using the Matlab/Simulink, the simulation model for the wind farm power control system was established. Taking the wind turbulence as an example, the simulation research on the active and reactive power regulation process was conducted for grid-interconnection of wind farms. Theoretical research and simulations prove the strategy feasible and effective.
