A field-weakening control is required in order to achieve high power output and stable control in the voltage saturation region. In this paper, a voltage phase-operated field-weakening control and a frequency-compensation control are presented. The voltage phase operation control adjusts the voltage phase command with the voltage maintained at the maximum value. Therefore the proposed control can...
This paper proposes to simulate the characteristics of wind turbine by PMSM (permanent magnet synchronous motor). On the aspects of wind turbine power-speed curve and torque-speed curve as well as PMSM open-loop and closed-loop control, the characteristics of wind turbine and PMSM are compared and analyzed. PMSM can simulate part of characteristics of wind turbine by open-loop frequency control, and...
