- Description
In this project, the operation and performance of the three-leg VSI control and the four-leg VSI control are studied for grid connected applications and for autonomous operation .The voltage source inverters are modelled and simulated in the stationary frames Alpha-Beta and AlphaBeta-Gamma in order to perform the system control action employing proportional resonant compensators. The simulations are performed in PLECS that can be used standalone or integrated with MATLAB/Simulink. The three-dimensional space vector modulation technique is implemented as a C-script for the control action of the four-leg VSI. Furthermore, the independent control of each voltage phase at the point of common coupling for standalone operation using the four-leg VSI topology is implemented in a stationary frame to deal with balanced and unbalanced loads in order to improve the power quality that is sent to the AC system.
