ABSTRACT
The article presents the analysis results of the physical environment of the data transmission between the technological equipment of automated dispatch control systems via RS-485. The purpose is to minimize the average functional level implementation cost of the automated dispatch control systems of distributed energy facilities through the organization’s communication of equipment of lower level. In the article the analysis of approaches to communication equipment, analysis of wire line to be used as a physical medium for transmission of data and development of recommendations and proposals for the use of wired communication lines of the twisted pair and RS-485 for data transfer.
