A METHOD OF CONNECTING IMPORTANT LOADS TO BACKUP POWER

Abstract

Increasing the productivity of electrified agricultural and processing industries requires the development of methods to increase the reliability of their power supply. In order to reduce the mass failures in electrical networks caused by weather and climatic conditions, the power supply of agricultural consumers must be reserved by autonomous sources. (Research purpose) The research purpose is developing a new way to connect responsible consumers to a backup power plant, which will allow only responsible consumers to be connected to diesel power plants during the outage of grid. (Materials and methods) Analyzed emergency situations, 70-80 percent of all interruptions in the power supply of agricultural electrical consumers are due to damage to the lines feeding them, while 90 percent of such damage occurs in overhead lines. (Results and discussion) Of all the measures aimed at increasing the reliability of power supply, a special place is occupied by the development and improvement of methods that allow you to quickly connect a responsible consumer to a backup power plant. The use of the local reserve is especially relevant in connection with serious quantitative and qualitative changes in the agricultural and processing industry. During the outage, when feeding responsible consumers from the main line, diesel power plants are most often used as such a backup means. (Conclusions) The proposed method allows powering consumers when connected to a backup diesel power plant by implementing an algorithm for selecting responsible electrical receivers. This will make it possible to increase the reliability of power supply to responsible consumers and reduce the outages.
