Development of a consensus algorithm and data block structure based on digital blockchain technology for distributed systems for storing information about the state of power equipment

Abstract

The article considers the main directions of technological transformations in the Russian electric power industry, which performs an integrating function for the fuel and energy complex of the country. The methods of achieving and ensuring a high level of reliability and safety of power equipment for thermal power plants, hydroelectric power plants, and nuclear power plants at all stages of their life cycle from design to decommissioning are considered. The issues of creating a unified system of information support for power equipment of generating systems for thermal power plants, hydroelectric power plants, nuclear power plants and power complexes based on renewable energy sources, taking into account the technical condition during the entire life cycle, are studied. In order to improve the security and efficiency of planning and forecasting of power equipment operation modes, it is proposed to consider an information model consisting of a centralized data warehouse and a distributed registry based on blockchain technologies. The principle of operation of a distributed closed registry, the structure of data blocks, and the algorithm of consensus between private users of the registry are considered.
