【摘要】 构建了一个可以运行于多种工况的变速恒频风力发电机组整机系统。在研究了风力发电机组各子模块数学模型的基础上,分析了发电机组的运行特性及各工况下的控制策略,建立了基于M atlab/S imu link的变速恒频风力发电机组无扰切换整机模型。初步实现了风力发电机组并网控制、低风速下的最大风能追踪以及额定风速上恒功率控制等功能。通过仿真曲线,验证了该系统的正确性和可行性。更多还原

【Abstract】 An integral wind power generation set is developed,which can operate under various circumstances.Through analysis of the mathematical models of individual sub-blocks,and the control strategy of the wind power generation set,the non-interference switching integral model is established based on MATLAB/Simulink.It can help to connect the generator with the grid,track the maximum wind power and control the power at rated wind speed.Simulation curve shows that the system is accurate and practical.更多还原
