The article presents a three-phase mathematical model of asynchronous machine with wound rotor based on differential equations. The equations are resolved with respect to the derivatives of flux linkages. The description of the computer program in the Matlab Simulink that implements the model and allows to simulate transients of the asynchronous motor is present. A simulation model of a three-phase asynchronous machine with wound rotor, which allows to investigate static and dynamic operating ranges when power converters are connected to the rotor circuit has been obtained. The results of approbation of the obtained simulation model in the Matlab Simulink environment and experimental research of asynchronous engine with wound rotor, driving into the asynchronous-valve cascade, are presented. The results of experimental studies of the asynchronous machine under sinusoidal voltage using a stand based on the asynchronous-valve cascade, and comparison of the oscillograms obtained with simulation results of the proposed model are presented. The comparison of experimental and calculated oscillograms of the current of the investigated asynchronous motor can be concluded on satisfactory accuracy of the proposed model and the possibility of its application for modeling and analysis of asynchronous electric drives.

Предложены новые методические подходы и компьютерные программы, существенно упрощающие проведение расчетов по оценке масштабов рассоления пород продуктивных комплексов при разработ­ке месторождений с использованием пресных и слабоминерализованных вод для вытеснения нефти. Проведены расчеты объемов растворенного и вынесенного с попутными водами катагенетического галита при эксплуатации скважин Северо-Домановичского месторождения, что позволило оценить масштабы рассоления коллекторов и выдать рекомендации по регулированию его разработки.

New methodological approaches and computer program s that significantly simplify the calculations for assessing
the extent of desalinization of rocks in the productive complexes during field development using fresh and low-mineralized water to force out the oil have been proposed. The volumes o f dissolved and removed with associated
waters catagenetic halite during the wells operation of the Severo-Domanovichskoye oil field were calculated,
which allowed us to evaluate the extent of desalinization of the reservoir rocks and to give recommendations for
regulating its development.

Прапанаваны новыя метадычныя падыходы i камп’ю тэрныя праграмы, якія iстотна спрашчаюць правядзенне разлікаў па ацэнцы маштабаў рассалення парод прадуктыўных комплексаў пры распрацоўцы радовішчаў з выкарыстаннем прэсных i слабамінералізаваных вод для выцяснення нафты. Праведзены разлікі аб’ёмаў растворанага і вынесенага са спадарожнымі водамі катагенетычнага галіту пры эксплуатацыі свідравінаў Паўночна-Даманавіцкага радовішча, што дазволіла ацаніць маштабы рассалення калектараў і выдаць рэкамендацыі па рэгуляванні яго распрацоўкі.

Основываясь на текстах издания «The Guardian», автор проводит анализ наиболее частотной семантики эмотивных единиц, выражающих отрицательные эмоции. Определяются особенности их репрезентации в современном английском публицистическом дискурсе. Исследование расширяет знание в области языковой репрезентации категории эмотивности.

Based on the texts of «The Guardian», the author analyzes the most frequent semantics of emotive units that express negative emotions. The features of their representation in the modern English publicistic discourse are defined. The study expands knowledge in the field of linguistic representation of the category of emotivity.
