Research on Sensorless Vector Control of Permanent Magnet Direct Drive Wind Power Generator
摘要
Abstract
Sensorless control technology is the focus of the research in back-to-back directly driven permanent magnet synchronous generator system. Based on the mathematical model of the double Y shift 30°six phase permanent magnet synchronous generator, a saturated function-based the new sliding mode variable structure observer was designed to estimate the position and speed of rotor. The estimated results were used to realize sensorless vector control of the permanent magnet synchronous generator. Simulation and experimental results show that the design of sliding mode variable structure observer for the disturbance of load has strong robustness,and estimated exact rotor operation in a wider range of frequencies. Through monitor the change of the wind speed to adjust generator speed in order to capture the maximum wind-energy in the generator side system.关键词
