"The article analyzes the structure of relay protection devices of various designs. Based on the Unified Electric Power System of the Republic of Kazakhstan prediction on the electric energy balance the plan to increase the generation of electricity due to the commissioning of new capacities was revealed In addition, the international market of the energy sector and a preliminary forecast for the total demand for energy separeted into the declared scenarios and the scenario of sustainable development of electricity generation, cumulative average annual growth rate, electric capacity by countries, continents and regions were studied. It is determined that the type of power generation system and the fuel used affect the features of building and updating relay protection systems. The hypothesis of the study is the replacement of existing closed solutions on the market of relay protection systems with open hardware and software, which allow developing and applying then various power supply systems, including FPGAs. Within the framework of the study, solutions for building a microprocessor relay on an open architecture were proposed: a block diagram and a developed laboratory stand “relay protection microprocessor on an Arduino board”; «Relay protection microprocessor using FPGA». Comparative data on the characteristics of the boards are presented, where the FPGA board is more effective in all respects. The program was developed in the Quartus Prime 21.1 Lite Edition environment. Based on the results of the work, it can be noted that aim of the further research will be the expansion of the microprocessor relay protection devices based on an open architecture use.
