Abstract
This study presents a two stage solar water synchronous reluctance motor (SynRM) driven water pumping system. In this system, to optimize the output of solar PV (photovoltaic) array, a DC/DC converter is used. An incremental conductance based maximum power point technique (MPPT) is used for controlling the DC-DC converter to attain soft starting of the three phase SynRM. In this work, a SynRM is used because of its some inherent characteristics. The simple structure of SynRM makes it ideal for industrial drive arena, especially at low power. The SynRM is substantially highly efficient than other conventional drives used for water pumping. A direct torque control (DTC) technique is used for controlling the SynRM drive. DTC technique is used in this work, because of its simple implementation, less sensitive to parameters variation and no need of co-ordinate transformation. The proposed system is designed, modelled and simulated in MATLAB/Simulink platform. The design and control of the proposed system are validated by simulated results.
