Анализ показателей качества электрической энергии при работе асинхронного двигателя от трёхфазного источника питания

Abstract

Данная научная статья посвящена вопросам исследования и анализа показателей качества электрической энергии при работе асинхронного двигателя от трёхфазной сети в лаборатории электромагнитной совместимости и качества электроэнергии Политехнического института (филиала) ФГАОУ ВПО «СВФУ имени М.К. Аммосова» в г. Мирном. Поставлены задачи измерения и анализа показателей качества электроэнергии. Рассмотрены вопросы обеспечения норм качества электроэнергии. Определен перечень измеряемых характеристик в соответствии с требованием ГОСТ 13109-97. Рассмотрены различные схемы подключения анализатора к трехфазной сети. Приведено описание программного обеспечения для работы с измеренными показателями качества электроэнергии. Получены и проанализированы результаты измерений, произведенных за сутки согласно ГОСТ 13109-97. Исследованию подлежали действующее напряжение и напряжение основной частоты, установившееся отклонение напряжения, частота, коэффициенты несимметрии напряжений по обратной и нулевой последовательностям, коэффициенты искажения синусоидальности кривой напряжения, коэффициенты n-ой гармонической составляющей напряжения, кратковременная доза фликера, угол фазового сдвига между фазными напряжениями, активная и реактивная мощности, коэффициент мощности. Сделаны выводы и заключения по полученным результатам.

This scientific article is devoted to the study and analysis of the quality of electrical energy in the work of the asynchronous machine from three-phase network in the laboratory of electromagnetic compatibility and power quality Polytechnic Institute (branch) «NEFU name after M.K. Ammosov» in Mirny. The task of measuring and analysis of the quality of electricity. The problems of ensuring the quality standards of electricity. The list of the measured characteristics in accordance with the requirements of GOST 13109-97. Various schemes connect the analyzer to the three-phase network. The description of software for the work with the measured parameters of quality of electric power. Received and reviewed the results of measurements made per day according to GOST 13109-97. The study was subject to the applicable current and voltage of the fundamental frequency, steady-state voltage deviation, frequency, coefficients unbalance voltage reverse and zero sequences, the coefficients waveform distortion voltage coefficients of n-th harmonic component voltage, short-dose flicker, the angle of phase shift between phase voltages, active and reactive power, power factor. The findings and conclusions on the obtained results.
