Information Provision for Monitoring the Current State of Electric Power Facilities

The chapter provides materials for the implementation of such problem as creating information support for monitoring the current state of electric power facilities (EPF) as a task of identifying the state of the facility based on the study of vibronoise signals generated by it. The proposed system of statements of the formation of vibronoise signals makes it possible to apply the concept of EPF research in the form of a sequence of its components—object-energy-information-model-measure-algorithm-program-result. The description of the physical mechanism of the formation of vibronoise signals in space and time of the EPF’s environment became the rationale for the vibronoise signal model in the form of a random spatiotemporal vibronoise signal field. The use of linear models of random functions in mathematical modeling makes it possible to determine the characteristics of identifying the state of the EPF. Random linear processes with discrete time, autoregressive processes, linear periodic random processes with discrete time, linear random fields are given and their identification characteristics are determined. The features of computer simulation of vibronoise signals are considered. The results of modeling experiments are presented to substantiate the choice of software pseudo-random generators of uniformly distributed numbers during modeling sequences of stationary white noise. On the next step, these sequences are used to form realizations of linear models of vibronoise signals. On the basis of the research results, conclusions were formulated on the creation of information provision for monitoring the current state of the EPF.
