RESEARCHING OF MARGINAL ERRORS OF DETERMINING PARAMETERS OF ELECTRICAL NETWORK ELEMENTS MODELS

Abstract

In this article based on the classical theory of errors method to solving the problem of estimating the influence on the accuracy of identification the parameters of the model of the lines and transformators by vector measurements both of the metrological characteristics of the measuring instruments and of the parameters of the regime is proposed. The application of this method makes possible to determine the areas of regimes that are optimal for carrying out measurements and also to formulate requirements for measuring instruments.
