Photovoltaic (PV) System Applied To Induction Motor Drives

Abstract

The aim of this paper is to utilize the advantages of Photovoltaic (PV) system in the field of motor drives. PV system is a promising field which has a great interest of many researchers and industries. This is due to its less effects to the environment, less operating cost and its suitability where the PV energy is extracted from the sun. Induction motor drives are very important field in which they used in various industrial and consumer applications. The construction of induction motor drive require a DC voltage to operate the inverter. Commonly this DC voltage is obtained from converted AC line voltage. This is require additional conversion and filtering circuits in order to supply the required DC voltage to the inverter. In the proposed design of this paper, a PV system is used to supply the required DC voltage to the inverter in order to reduce the construction cost and complexity of the induction motor drive with a converted DC source. The motor drive with a DC source and with PV system were designed utilizing MATLAB/SIMLINK environment. Performance comparisons of the two designs were carried out in terms of speed, current and torque response. The results shows that, drive performance with PV system is better than the drive performance with DC source in terms of overshoot, rise time, settling time, speed variation and load disturbance.
