The Small-Scale Wind Power Electricity Generation Training System enables students to study the complete process of wind power electricity generation directly in the classroom. The training system also covers the storage of electrical energy in batteries to ensure that it is available when there is no wind or during low wind periods.
The training system features the Wind Turbine Generator/Controller, Model 8216, and the Four-Quadrant Dynamometer/Power Supply, Model 8960-2. The Four-Quadrant Dynamometer/Power Supply is used as a prime mover in order to drive the wind turbine generator. By varying the rotation speed of the prime mover and the current through the generator windings, students can measure the generator parameters for different speeds and load values. The prime mover is also used to emulate wind blowing on the blades of a wind turbine rotor. In this mode of operation, the prime mover’s torque-speed characteristic is identical to the torque-speed characteristic that would be obtained at the wind turbine rotor for different wind speeds. This allows students to plot the typical curves of the wind turbine. Finally, the wind turbine controller can be used to adjust the charge current of a storage battery in order to maximize the amount of energy stored in the battery at any wind speed.
