Performance analysis of VSI based standalone PV generation system connected to induction motor

摘要

Renewable energy sources like wind & solar can be regarded as the acceptable alternative for conventional energy sources. The standalone photovoltaic system basically used to provide the electricity to the remote areas. This study illustrates the performance analysis of 3-phase induction motor working as a load with PV array is connected. In this paper input voltage of the inverter is a step-up by dc/dc boost converter. Designed boost converter with MPPT boosts the voltage that is developed by the PV array to a specific required value that can run satisfactorily the 3-phase induction motor. The inverter transforms the DC voltage to the AC that is controlled with the help of SPWM-VSI techniques, as the inverter output voltage is not pure sinusoidal so LC-filter is used to obtain the proper sine waveform. Thus output voltage of Inverter can be used to operate the 3-phase induction motor at different loading. The acceptable results are procured for the given loads and the load voltage is found to be steady under varying load setting.
