Improved Standalone PMSG based Wind-Generating System Using MPPT and MRAS for Speed Estimation

Conference Paper


Abstract


  • The speed estimation method is used in order to eliminate the mechanical sensor for measuring the rotating speed of the permanent magnet synchronous generator (PMSG) which is applied in the standalone generating system, a sensorless method is presented in this paper. The speed is estimated based on the model reference adaptive system (MRAS). The proposed system contains a wind turbine, boost converter followed by uncontrolled rectifier, PMSG, battery storage system, bidirectional converter, three-phase inverter, filter, and three-phase load. There are three goals of the suggested control as follows; achieve the maximum power point tracking (MPPT), adjust the DC-link voltage, and keep the output load voltage constant. The PMSG rotating speed is estimated via the MRAS and it is used as feedback in the MPPT control loop. The flux linkage method is adopted in the MRAS. The performance of the proposed system and the suggested control strategy are examined under different circumstances. The extensive simulation results validate the good robustness of the estimation method and the presented control strategy.
