Mengesha Mamo Abstract— This paper presents an alternative closedloop control strategy approach of generator side two- -level voltage source converter to regulate the dc link voltage. In this tutorial, the theoretical foundation of overcurrent relay is formulated and it will be designed in MATLAB/Simulink. If the number of levels is increased it results in increase in number of H-bridges. A 10 ohm load is fed in DC through a three-phase rectifier from an inductive source (5 mH; 120 V rms). A 100-kW PV array is connected to a 25-kV grid via a DC-DC boost converter and a three-phase three-level Voltage Source Converter (VSC). With Simulink, experimental models can be easily built from the scratch and existing models can be modified to the user's needs. to power system faults such as three-phase-to-ground, single-phase-to-ground, phase-to-phase and two-phase-to-ground are created in transmission line model for generation of different types of voltage sag. The Current Source (Three-Phase) block models an ideal three-phase current source that maintains sinusoidal currents of the specified magnitude through its terminals, independent of the voltage across the source.
