Abstract：This paper introduces pitch control system for wind turbine and analysis the direct current(DC) and alternating current(AC) pitch control system for present wind turbines. By comparing with advantages and disadvantages of respective, further more the design of the pitch control system for wind turbines was presented which was AC pitch control system for wind turbine based on PLC in accord with the technology developing tend. Using PLC as a main controller, with control of a flexible manner, simple programming, good performance on stability and so on. Experiments show that the results can achieve a certain degree.
