SUBSTANTIATION OF THE DEVELOPMENT OF A COMBINED MMETHOD OF IDENTIFICATION OF ELECTRICAL RECEIVERS IN A POWER GRID AND MEANS OF ITS IMPLEMENTATION

Methods based on the analysis of electrical, thermal, acoustic, and optical parameters are used to identify electrical receivers connected to the same power grid and monitor their operating modes. These methods are used individually (separately from each other). In the well-known publications of domestic and foreign scientists, the issues of using the noted methods for identifying identical electrical receivers (if there is more than one electric receiver in the grid), as well as for consumers with a difficult-to-predict load schedule, have not been considered. Consequently, these methods do not allow to identify electric receivers with a high reliability. (Research Purpose) The research purpose is substantiating the development of a combined method for identifying electrical receivers in the power grid and the means of its implementation. (Materials and methods) The analysis of literature sources considering methods of identification and monitoring of operating modes of electric receivers and means of their implementation is carried out. Foreign and domestic sources on the research topic were used mainly for the last 5 years. Based on the analysis of existing methods, their classification is proposed, a combined identification method and a block diagram of the device for its implementation are developed. (Results and discussion) A classification of methods for identifying and monitoring the operating modes of electric receivers is proposed, including methods based on the analysis of electrical, thermal, acoustic, optical parameters. A new combined method using the analysis of electrical and acoustic parameters for the identification of electrical receivers is proposed, and its justification is carried out. A block diagram has been developed for the implementation of the proposed method. (Conclusions) It is established that in order to reduce the probability of error in determining the type of load, it is advisable to use a combined method combining electrical and acoustic methods. When developing a device, it is necessary to divide the blocks into a measuring and recognition unit. To identify the electrical and sound spectra of electrical receivers, the most reliable (from the point of view of accuracy) is the use of artificial intelligence technology.
