ON SOME PECULIARITIES OF DESIGN OF INTELLIGENT MULTI-LEVEL SYSTEMS FOR TECHNICAL DIAGNOSTICS OF ELECTRIC POWER FACILITIES

The main goal of the paper is the development of structure of intelligent distributed multi-level system for technical diagnostics of power electrical equipment. The discussed system implements the following general principles: distribution of computational resources between different levels which is needed to support required periodicity of measurements and signal processing; structuring of the diagnostic information on hierarchical principle; classification of the diagnostic information by severity level for the optimization of information exchange. This structure of the developed system complies with the basic requirements of the Smart Grid concept: bi-directional exchange of information between system elements, and decentralization of computing resources. One possible implementation of the system is discussed, which consists of 4 hierarchical levels typical to an average power plant. The structure represents central diagnostic system, a number of local diagnostic systems and intelligent measuring devices. The paper details the logic of data exchange between different hierarchical levels and their main functions.
