| Abstract: | The operating principle of electric pitch system of megawatt wind turbine is introduced in this paper, and three-phase permanent magnetism synchronous motor(PMSM) is chosen as the executive motor of the proposed system. Based on the analysis on the operating principle of electric pitch and the control strategy of servo-control system, an electric pitch servo-motor control system composed of a PMSM and its servo-drive controller is designed. Experimental result is given to verify the reliabilities of theoretical analysis and designed system, also it is useful for reference of designs and application in a practical engineering. |
