- Abstract
Modern distribution networks are characterized by an increase in electrical loads, varying both in phases and over time. Dynamic changes in the operating modes of the load phases have a negative impact on the efficiency and throughput of distribution networks. The use of currently available approaches and technologies for managing network operation modes makes it possible to effectively combat these negative phenomena. The practical implementation of such approaches is based on the use of various devices that automatically affect the operating modes of the distribution network, taking into account the operating modes of the load phases. Choosing the most effective solution depends on many factors. These include the physical parameters of the distribution network and the nature of the loads, the goals and objectives of managing the modes of operation of the network, and the functionality and technical and economic indicators of control devices. At the initial stages of technology assessment, it is important to have an approach that allows one to identify their differences when solving tasks. As such an approach, it is proposed to calculate the operating modes of distribution networks using mathematical models of devices in the MATLAB Simulink environment. The results of calculations of the operating modes of three- and four-wire distribution networks at the specified parameters of the network phases and load are presented. The analysis of the influence of various control technologies on the operating modes of the distribution network is carried out on the example under consideration. Among such technologies, the following are considered: zero sequence current compensation, reactive power compensation, phase power symmetry, symmetry with simultaneous compensation of reactive power in the phases of the distribution network. Brief information about the devices implementing the technologies in question is provided.
