ADVANCED CONTROL OF INDUSTRIAL SOLAR VARIBLE SPEED DRIVE FOR THREE PHASE INDUCTION MOTOR

In this paper, an efficient use of solar energy can be achieved by operating Photovoltaic (PV) panels at the maximum power point (MPP) for powering the induction motor. Such mechanisms are very useful where other sources such as grid power supply and other renewable sources are not easily available. These induction motors are more economical due to less maintenance and operation cost. The main components of solar-powered induction motor system are the solar panel, control board, and motor set. The proposed system implemented the application to give power from solar energy to motor with the help of induction motor drive by converting the DC electric power generated from a PV panel to AC power using the inverter. In the proposed work solar panel of 2.4 kW, power generating capacity is used. Induction motor used is of 3 HP power rating. Three control strategies are used in this work namely Carrier based Pulse Width Modulation (PWM), Field Oriented Control (FOC), and Maximum Power Point Tracking (MPPT). This paper discusses multiple techniques for computational demonstrating of Maximum Power Point Tracking like Perturb & Observe (P&O) and Incremental Conductance (Inc.) with Field Oriented Control Drive. The control techniques are implemented by using Matlab/Simulink. The simulation results clarify the effectiveness of the controllers based on Incremental Conductance techniques with Field Oriented Control for each performance index as it provides lower overshoot value and lower rising time and high dynamic response.
