Abstract

The work analyzes the correctness of the functioning of the photovoltaic system with a rated electrical power of 3500 W, consisting of 14 photovoltaic modules and a power electronic converter in the form of a single phase voltage inverter equipped with a maximum power point tracking system, disturbed by voltage stroke. The voltage surge with the parameters 1.2/50 µs, simulating a lightning discharge, was introduced into the system from the power grid side. For the purpose of computer simulation performed in Matlab/Simulink, the recommendations included in the PN-EN 61000-4-5 standard "Immunity of the surge disturbances" were used. Significant changes in the voltage and current on the AC side, related to the system of energy return to the power grid were shown.

Highlights

The immunity of a working device or system is understood as the ability to work during interaction of a certain electromagnetic disturbances
Due to the harmfulness of immunity tests for selected electromagnetic disturbances [6], it is reasonable to use computer simulation tools to make a model of a photovoltaic installation working during the disturbance [7]
The photovoltaic system is a combination of component devices that allow obtaining solar energy, its conversion into electricity based on the solar effect in the material structure and the adjustment of electrical signal parameters to the requirements of a AC grid or powered electric receivers

Summary

Introduction

The immunity of a working device or system is understood as the ability to work during interaction of a certain electromagnetic disturbances. Laboratory tests of equipment immunity to electromagnetic disturbances such as electrostatic discharge, electrical fast transients or surges are standardized [1]. The assumptions of Polish Energy Policy until 2030 put a lot of emphasis on electricity generation [2] including photovoltaic installations, which makes them popular and widely used in Poland and in the world [35].
