PROJECT TITLE :

Maximum Power Point Tracking Control of IPMSG Incorporating Loss Minimization and Speed Sensorless Schemes for Wind Energy System

ABSTRACT:

Within the variable-speed generation system, the wind turbine (WT) will be operated at most power operating points by adjusting the shaft speed optimally. This paper presents a unique maximum power point tracking (MPPT)-primarily based management of interior permanent-magnet (IPM) synchronous generator incorporating loss minimization algorithm (LMA). In the proposed technique, without requiring the data of wind speed, air density, or turbine parameters, MPPT algorithm generates optimum speed command for speed management loop of vector-controlled machine side converter. The MPPT algorithm uses the estimated active power output of the generator as its input and generates command speed so that most power is transferred to the dc link. The proposed control system additionally incorporates a LMA to minimize the losses within the generator and hence to enhance the potency of the wind energy conversion system (WECS). A speed sensorless scheme is additionally incorporated to extend the reliability of the system. The performance of the proposed adaptive MPPT management of wind generator incorporating loss minimization and speed sensorless schemes is tested in both simulation and experiment at variable wind speed conditions.
