      <abstract xml:lang="ru">
        <p>В статье рассматриваются вопросы выявления местоположения нелинейной нагрузки в электрических сетях, вносящей основной вклад в искажения несинусоидальности напряжения и тока в распределительной сети промышленного предприятия, включая предприятия горнодобывающей отрасли. Рассмотрены существующие методы определения местоположения источника высших гармонических составляющих в напряжении и токе, выявлены их преимущества и недостатки. К основным недостаткам применяемых методов следует отнести невысокую точность и некорректность их использования на действующих предприятиях. При разработке нового метода перед авторами стояла задача простоты его использования в условиях промышленной эксплуатации электрооборудования и безусловной корректности полученных результатов. Предложенный метод выявления источника высших гармоник основан на варьировании параметров энергосистемы, в частности, изменении сопротивления силовых трансформаторов с учетом коэффициента их трансформации. Показано, что при варьировании коэффициента трансформации при регулировании под нагрузкой изменяется суммарный коэффициент гармонических составляющих напряжения. На основании построенных зависимостей проанализировано изменение производной данной функции при различных вариациях параметров источников высших гармоник и разработан метод, позволяющий определить долевой вклад потребителей в суммарный коэффициент гармонических составляющих напряжения.</p>

        <p>The article discusses the issues of identifying the location of non-linear loads in electrical networks which makes the main contribution to the distortion of the non-sinusoidal voltage and current in the distribution network of an industrial enterprise, including mining enterprises. The existing methods for determining the location of the source of higher harmonic components in voltage and current are considered, their advantages and disadvantages are revealed. The main disadvantages of the methods used include the low accuracy and incorrectness of their use in existing enterprises. When developing a new method, the authors were faced with the task of simplicity of its use in the conditions of industrial operation of electrical equipment and the absolute correctness of the results obtained. The proposed method of identifying the source of higher harmonics is based on the variation of the parameters of the power system, in particular, the change in resistance of power transformers taking into account their transformation ratio. It is shown that by varying the transformation ratio during regulation under load, the total coefficient of the harmonic components of the voltage changes. Based on the constructed dependencies, the variation of the derivative of this function with different variations of the parameters of sources of higher harmonics is analyzed and a method is developed that allows determining the share contribution of consumers to the total harmonic component of the voltage.</p>
