Abstract

According to statistics, losses in electrical networks of power supply organizations in the Russian Federation amount to 10 percent, while the world average is 8 percent. The Energy Strategy for the period until 2035, approved by the Government of the Russian Federation in 2020, sets the goal of achieving a reduction in electrical energy losses to 7.3 percent by 2035. One of the effective ways to reduce electricity losses is to replace underloaded transformers at substations in order to increase the transformer load factor. For this purpose, a method was developed for using two transformers instead of one at 10/0.4 kilovolt transformer substations. (Research purpose) is to develop an algorithm for implementing a method of using two transformers instead of one at 10/0.4 kilovolt transformer substations in order to reduce electricity losses. (Materials and methods) General scientific research methods, methods for constructing algorithms, control and data transmission systems, and analysis of scientific and technical information were used as the methodological basis for the research. (Results and discussion) This paper presents an algorithm for implementing the method of using two transformers instead of one at 10/0.4 kilovolt transformer substations. The algorithm allows automatically controlling the connection and disconnection of power transformers at a transformer substation depending on their load and season, while recording these actions and sending the corresponding signals to the dispatcher of the power supply organization. (Conclusions) Based on the results of the study, it was found that the developed algorithm for implementing the method of using two transformers instead of one at 10/0.4 kilovolt transformer substations makes it possible to achieve a reduction in electricity losses by increasing the load factor of transformers.
