Identification of the State of the Distributive Electrical Network in the Automated Systems of Accounting and Management of the Power Consumption

Abstract

Distributive electrical network (DEN) is considered as an object of automation, which produces electricity as a marketable product. Development and introduction of modern automated control systems and electricity accounting (ACSEA) makes topical the problems of identification of the electrical state of DEN and localization of the coordinates of the uncontrollable (non-normative) disturbing factors, such as unsanctioned use of electricity and leakage currents in the network. Application for this purpose of the existing methods and algorithms in real time presents certain difficulties, because of the stochastic character of separate network parameters, for example, active resistances of the interpersonal sections, which is changed depending on the external factors (temperature, humidity, etc). The paper offers the methodological and algorithmic basics for solving this problem, based on identification of the current state of the distributive electrical network in the presence of the distributing factors. The received results are oriented on development of special software corresponding to the functional tasks (subsystems) of ACSEA.
