Abstract :
The principle of wind turbine generator (WTG) and its control system based on programmable logic controller (PLC) are presented. The wind energy is converted into electric energy by WTG. Because of the uncertainties of the speed, the direction of the wind, and the large inertia of the wind turbine of WTG, reliable control strategies are adopted to assure the WTG to run normally under serious conditions. According to the special requirement of the control system of 55 kW WTG, a gate method is used to get the precise measurement of the generator´s speed. The generator can be merged into or disengaged from the power system safely by the control system. The crosswind protection of the wind turbine and casting loose automatically are also realized. The practical running results show that the control system is reliable
