基于混杂系统的风力发电机组建模与控制

针对风力发电机组系统固有的混杂系统典型特征,运用混杂自动机理论和混合逻辑动态理论建立了风力发电机组的混杂模型,设计了基于自动机模型的全程混杂控制系统,并以1台额定功率为300 MW的变速变桨距风力发电机组为例进行了仿真.结果表明:自动机模型可实现风电机组的全程模拟,自动机的混杂控制系统可满足风电机组全程控制的要求,而且基于混合逻辑动态模型的预测控制也实现了功率输出优化,证明了混杂系统理论应用于风力发电研究领域的有效性和实用性.

Modelling and Control of Wind Turbine Based on Hybrid System

Focusing on hybrid system typical feature of wind turbine,based on the theory of hybrid automata and mixed logical dynamics(MLD),a kind of hybrid model of wind turbine was built,and the hybrid control system based on automata model was designed.An example of a 300 MW variable speed and pitch wind turbine was simulated.Results show that the hybrid automata model can implement the global simulation of wind turbine,the designed hybrid control system can fulfill the global control demand,and the predictive cont...
