Prospects for further improvement of filter-compensating devices for agro-industrial complex consumers

Abstract

Energy saving in technological processes of agro-industrial complex is an integral part of the development of a market economy, since nowadays there is a total interest of suppliers and consumers in economical energy supply. At present, the concept of electromagnetic compatibility in matters of power quality assurance covers almost any type of interaction between various devices and systems using electromagnetic phenomena, as well as the interaction of these systems with living organisms. There is an increasing need to analyze the impact of energy losses on energy efficiency in general and the need to analyze additionally arising losses caused by a sharp deterioration in the power quality readings. At present stage, more accurate information is required about the state of the electrical networks modes to determine the level of losses and reduce the commercial component of losses. In this situation, power systems require more accurate forecasts of the load of distribution networks in order to achieve excellence in operation, planning the development of networks and optimization of energy resources management, but the process of high-quality compensation remains rather complicated due to the growth of distortions in low-voltage distribution networks. In contrast to the existing solutions, the authors of the article offer to introduce into the method (algorithm) for controlling a compensation device the operation of forecasting the value of active power of non-stationary non-linear load on the forthcoming period of the supply mains voltage according to the results of monitoring the change in the active power of the load during the previous periods and statistical processing of the data obtained.
