Optimised Solar Power Fed Induction Motor Drive for Water Pumping Application Along with Load

Abstract

With the brisk utilization of non-sustainable resources, inexhaustible resources like sun powered energy, wind energy, hydro energy, etc. needs to be upgraded for proper utilization. Nowadays, photovoltaic (PV) system's energy, based on sunlight is most widely used energy source. The efficiency of the PV system will change with the change in parameters like voltage, current and temperature due to its non-linear PV characteristics which may be overcome with the help of controllers at different stages of operation. In this paper, the Simulink model shows the behavior of solar power fed 3-phase, 5 HP induction motor (IM) at different load conditions along with the additional load of 150 kW present in the system. A PV array with maximum power of 262 kW along with Boost Converter and 3-phase inverter has been simulated. The maximum power point tracking (MPPT) controller has been implemented in order to extract the maximum power from the PV array. A closed loop controller has been implemented to control the 3-phase inverter according to the load conditions. The results related to the behavior of 3-phase induction motor drive and PV system at different stages of operation has been discussed
