The paper describes the development of a windmill simulator, to simulate accurately the movement of a windmill. The simulator has a model to facilitate the change of windmill parameters, such as power coefficient or moment of inertia, by overcoming the weak points in the research and development environment for wind utilization, especially with the purpose of improving methods of windmill speed control or output. Also, to determine further the dynamic characteristics of the windmill speed with great accuracy, the simulator has a motor model to compensate for the slow response of the DC motor itself. The simulator is mainly composed of a separately‐excited DC motor to directly simulate the movement of the windmill, a high‐output DC amplifier to drive the motor, and a personal computer for control. It is ascertained that the developed simulator can fully reproduce the stationary and dynamic characteristics of a windmill from the experimental results. Also, a method is described to control the blade pitch angle to keep a windmill rotational speed constant. The results of the numerical simulation agree with the characteristics of the windmill simulator, and the effectiveness of the blade pitch angle control of the simulator is also affirmed.
