摘要
风力发电系统是具有不确定性的复杂非线性系统,机组运行工况变化十分频繁。通过对风力发电机组的系统特性分析,发现风力发电系统呈现出混杂系统的典型特征。因此,基于混杂自动机理论建立了1.5 MW双馈型风电机组的混杂动态模型,并根据风力发电机组控制策略设计了能够在机组运行中实现全程自动化的混杂控制系统。仿真结果表明,基于混杂自动机的动态模型可以实现风电机组的全程模拟,所设计的混杂控制系统能够满足风电机组全程控制要求,证明了混杂系统理论应用于风力发电研究领域的有效性。
Wind turbine generator （WTG） system is a complex nonlinear system involving some uncertain disturbances, and its working states change multifarious. A fact was discovered that wind turbine generator showed the typical feature of hybrid system by analyzing its characteristics. Therefore, the hybrid dynamic model of 1.5 MW Doubly-fed WTG was built based on theory of hybrid automata, at same time hybrid control system was designed for solving the problem of the global automation according to the WTG control strategy. Emulation results present the hybrid automata model can accomplish the global simulation of WTG, and the designed hybrid control system fulfills the demand of WTG global control. Moreover, the validity and practicability of applying hybrid system theory in the field of wind power are demonstrated.
