| Abstract: | According to the important role of sensorless control technology for permanent magnet synchronous motor （PMSM） of megawatt direct-drive wind power converter, an estimation algorithm based on back electromotive force closed phase-locked loop （PLL） of motor was proposed, to which, simulation and test verification were conducted. Results show that the PMSM position can be calculated accurately by the estimation algorithm so as to achieve effective control over the PMSM in direct-drive wind power generation systems. |
