Mathematical models of computer intellectualization of the technology of vector-based synchronized measurements of electrical networks

This article analyzes the current state of scientific investigations in the sphere of intellectualization of electrical networks on the basis of synchronous phasor measurements in a system of registration of primary data. The optimization of electrical energy consumption is shown to be dependent on the informational completeness of primary multidimensional data. Based on differential transformations, mathematical models and methods are proposed to analytically compute a collection of T-discretes for determining the informational completeness of the obtained nondeterministic primary data. Methods are considered that make it possible to intellectualize technologies of synchronous phasor measurements with the help of representation of registered primary data in the form of T-spectra for determining individual harmonic components for each parameter of transient processes in power supply systems and also for performing spectral analysis (based on differential representations) and computing spectral density as the basis for the formation and accumulation of new knowledge. © 2016, Springer Science+Business Media New York.
