System for monitoring the operating parameters of the lighting complex with parallel power from two sources

Currently, there is an increase in the number of generating devices related to renewable energy sources, a large part of which operates on direct current. The growing number of generating and consuming units operating on direct current leads to the need to combine them to work in separate DC micro-networks. As parameters of operation modes in such micro-networks are constantly changing due to changes in flows of generated, accumulated and consumed energy, it becomes necessary to perform continuous monitoring in them. In micro-networks with generation of energy from photovoltaic installations, including those used in lighting systems, monitoring is performed by current, voltage and solar radiation. For this purpose, current sensors (DT) and voltage sensors (DN), as well as Peleng SF-06 piranometer are provided. Information from DT, DN and Peleng SF-06 piranometer is received through the input modules in a personal computer, where it is processed and displayed to the operator via software developed in the MasterSCADA 4D environment. This solution allows to develop a multifunctional monitoring system, on the basis of which the object dispatching system will be created, including lighting complexes. The lighting complex was developed with parallel power supply from two sources, one of which is a photovoltaic module. This complex can be used both for agricultural and industrial objects. The proposed monitoring system has been tested and used in the research of this lighting complex. The study has shown that it provides basic information on the operation of the lighting complex in the dynamics of the current, voltage and arrival of solar radiation.
