 The article analyzes the collaborative work of small power sources in a distributed generation system. The study was carried out on the basis of the power supply system of the Kairakkum carpet plant in Tajikistan is the main power source for which is the 126 MW Kairakkum hydroelectric power plant. To study the joint operation of small energy sources with the power system, a simulation model was compiled in the Matlab SIMULINK environment of the carpet mill’s power supply system in normal and emergency operating modes. The analysis of perturbations in the electric power system during the start-up of an additional electric power source in normal and emergency modes of operation is performed. The indications of the measuring devices are given in the corresponding mode and in the short-circuit mode. The main consequences of violation of the quality indicators of electrical energy are presented: an increase in current in the distribution network, an increase in the electromagnetic field in the windings of motors and transformers, an increase in losses in the supply and distribution networks. The acceptability of the use of small energy sources in conditions of a shortage of active and reactive power, while ensuring the standard quality of electrical energy has been proved.
