Abstract

Voltage Source Inverter (VSI) is one of the essential Power Electronic Converters (PEC) which is used to utilize the power from the Renewable Energy Sources (RES) in an efficient manner. Some of the RES produces power in the form of the dc. VSI is used to convert the dc power into ac power. Various control techniques are implemented to control the inverter circuits. This paper presents a performance analysis of current control with Revised Space Vector Pulse Width Modulation (RSVPWM) technique and Discrete Model Predictive Control (DMPC) technique. This analysis is performed on 3-phase VSI. Basic concepts, control circuits, mathematical models are explained and the control techniques are simulated using MATLAB / Simulink tool. Simulation results are presented and performances of the both control techniques are compared.

Abstract

Renewable Energy Sources (RES) are getting a great attention due to ever increasing power demand, environmental issues, and thrust toward sustainable development. The power produced from the RES like solar, wind etc. is used by the stand alone system or the feed into the electric grid. In this paper a 3-phase Voltage Source Inverter (VSI) is modeled and analyzed for grid connected Solar Photovoltaic (SPV) system. Mathematical model of three phase VSI and LC filter circuits are derived using state space analysis and Sinusoidal Pulse Width Modulation (SPWM) technique is proposed for 3-phase VSI. Harmonic elimination is done in VSI using by Pulse Width Modulation (PWM) technique by solving the non-linear equations that are used to determine switching angles of an inverter. The switching angle plays an important role to produce desired output by eliminating selected harmonics. The VSI is simulated using MATLAB/Simulink platform and harmonic elimination is done by considering bipolar switching case of the inverter. Various simulation results are presented to demonstrate the operation of the inverter. The harmonic spectrum analysis is carried out and discussed for the proposed harmonic elimination method
