New algorithms for calculation of tolerances, selection of measurable currents and diagnostics

This paper proposes a new effective algorithmic basis for solving the problem of choosing the permissible deviations of the parameters of the elements, choosing the measured currents and diagnostics of the electrical device elements. The algorithms developed by the authors are based on the new modification of the Gaussian elimination method to solve the systems of linear algebraic equations. One of the advantages of this modification is a significant reduction in computing costs for solving the problems to analyze the operating modes of the electrical devices and their topology. The algorithms for the synthesis of electrical devices are developed on the basis of this modification. The application of the proposed algorithms is described in choosing the permissible deviations of the parameters of the device elements that provide the given limitations on the changes in the electrical regimes when determining the branches of electrical circuits in which current sensors are located that provide monitoring of all device currents, also in the rationale of the choice of the measured currents and voltages used to estimate changes in the parameters of the elements in order to diagnose them.
