摘要
为了能在实验室条件下对风力发电技术进行研究,提出了采用直流电机模拟风力机工作特性的可行性方案。分析了风力机的工作特性及最佳风能利用原理,采用直流电机转矩控制方案实现风力机特性的模拟,建立了由工控机、信号采集卡和电力回馈加载控制器构成的风力机模拟硬件平台,利用C++Builder开发了风力机模拟控制软件,在此基础上形成了完整的风力机特性模拟系统。通过风速恒定、叶尖速比变化以及模拟自然风的实验验证了该方案的正确性。
In order to research wind power generation in laboratory,a feasibility plan to imitate the performance characteristic of wind turbine by using DC motor is proposed,then the performance characteristic and the operation principle of optimum utilization of wind energy are analyzed.Based on this principle,the torque characteristics of wind turbine are imitated by controlling the torque of DC motor.The whole wind turbine imitation system includes hardware platform comprising industrial computer,signal acquisition board,power loading feedback controller and wind turbine imitation software.The imitation is done under two typical condition of variable machine velocity and natural wind, experimental results of control system show the correctness of this programme.
