Рассмотреть трехфазную распределительную электрическую сеть (РЭС) напряжением 0,4 кВ, в которой ведется мониторинг (коммерческий учет) потерь электроэнергии автоматизированной информационно-измерительной системой контроля и учета электроэнергии (АИИС КУЭ). Решается задача оперативного расчета потерь электроэнергии имеющимися средствами АИИС КУЭ с целью выявления в РЭС несанкционированных отборов электроэнергии при условии неизвестных значений параметров схемы замещения сети, которые вследствие внешних климатических факторов могут существенн о изменяться. МЕТОДЫ. При этом используются одновременные измерения для одного и того же интервала наблюдения действующих значений тока и напряжения, а также активной и реактивной мощностей в начале РЭС и у каждого зарегистрированного в ней абонента . РЕЗУЛЬТАТЫ. Проведен анализ известных методов решения указанной задачи, показаны их недостатки и представлен а новая методика, использующая ра венство сопротивлений фазных и нулевого проводов в пределах межабонентского участка трехфазной РЭС. ЗАКЛЮЧЕНИЕ. Предлагаемая методика основана на предварительном оперативном расчете достоверных значений сопротивлений межабонентских участков при указанных условиях и может применяться в существующих АИИС КУЭ без внесения в них дополнительных измерительных средств (функций).</p></abstract><trans-abstract xml:lang="en"><p>THE PURPOSE. The process of o n-line calculation of electricity losses in three phase distribution electric networks (DEN) with a voltage of a 0,4 kV, where monitoring of electricity losses (commercial accounting) is carried out by an automated information measuring system of electrici ty monitoring and accounting (AIMS EMA) is considered. The problem of operative detecting of unauthorized power take -offs in the DEN under condition of unknown values of parameters of the network equivalent circuit, i.e. resistances of its interpersonal sections, which can change significantly over time because of external climatic factors (temperature, humidity, etc.) is being solved. METHODS. The procedure of the proposed calculation can be implemented by the available means of AIMS EMA. It is based on simultaneous measurements for the same observation interval of effective values of current and voltage, active and reactive powers at the beginning of the DEN and at each subscriber. In the course of periodic measurements of these mode parameters, the initial data used in the proposed calculation are formed. RESULTS. The analysis of the known methods of solving this problem is carried out, their disadvantages are shown and the new methodology, which is based on a preliminary operative calculation of reliable values of the resistances of interpersonal sections, provided that unauthorized power take -offs are possible in DEN is presented. While solving, the conditions of equality of resistances of the phase and neutral wires within the interpersonal section of th e DEN are used. The proposed method makes available the implementation of the operative calculation of technical losses in DEN and the identification of the commercial losses (unauthorized power take -offs) in it, as well as a detailed analysis of subscribe r data in order to detect the location (coordinate) and the amount of unaccounted electricity. CONCLUSIONS. The proposed methodology can be used in existing AIMS EMA without the introduction of additional measuring means (functions).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>распределительная сеть</kwd><kwd>параметры сети</kwd><kwd>потери электроэнергии</kwd><kwd>метод расчета</kwd><kwd>идентификация параметров</kwd></kwd-group><kwd-group xml:lang="en"><kwd>distribution network</kwd><kwd>network parameters</kwd><kwd>loss of electric power</kwd><kwd>calculation m parameter identification</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Tanveer A., Huanxin C., Jiangyu W., at al.
