Developing a three-phase converter to be used in a prototype of a virtual inertia system based on frequency and active power relationship

Abstract

The integration of power plants based on renewable energy sources (RES) into existing energy systems causes a number of problems, one of which is the violation of the stability of the generators parallel operation. One of the possible methods for the above problem solving is the use of virtual inertia systems (VIS). In this paper, we review the process of a converter developing for further use in a VIS prototype. The developed device converts direct current from a laboratory power supply into a sinusoidal three-phase voltage of industrial frequency. The switching of the converter’s power transistors is controlled through digital signal processor (DSP) TMS 320 F 28379 D via IR 2110 drivers. Using Altium Designer, a schematic diagram and layout of the printed circuit board of the converter were developed. Based on the manufactured printed circuit board, a converter was assembled, the correctness of its operation was checked, and a conclusion was made about the possibility of its use in the VIS prototype.
