Ushbu maqolada asinxron motor reaktiv quvvatini nazorat qilish va boshqarish uchun boshqariluvchan chiqish kuchlanishli tok o‘zgartkichidan foydalanildi. Tok o‘zgartkichining ishonchliligi, sezgirligi, o‘lchash aniqlik va xatoliklarining dinamik tavsiflari Simulnik dasturidan foydalanilgan holda olindi. Tok o‘zgartkichlari, asosan, asinxron motor elektr ta’minoti tizimining normal barqaror ish rejimi davrida ishlaydi. Bu rejimda ba’zi shartli chegaralar bilan tok o‘zgartkichlarini tadqiq etishda kirish tokining minimal va maksimal qiymatlari qabul qilinadi, buning uchun aniqlik sinfi (0,1‒1,2)∙Inom deb olinadi. Elektr jihozlar va tarmoqlardagi shikastlanishlar asinxron motor elektr ta’minoti tizimining halokatli ish rejimiga olib keladi. Bu holda tok o‘zgartkichlari dinamik rejimda ishlaydi. Asinxron motorda qisqa tutashuvlar elektromagnit tok o‘zgartkichlarining dinamik rejimlarda ishlashiga olib keluvchi asosiy sababdir. Elektromagnit tok o‘zgartkichlarining bunday rejimda ishlashi boshqaruv tizimi sxemalaridagi ishlash shartlaridan sezilarli farq qiladi. Agar elektromagnit tok o‘zgartkichlari o‘lchov maqsadida ishlatilsa, odatda, nominaldan oshmagan birlamchi tokda ishlashi talab etiladi. Bunda asinxron motorning boshqaruv tizimlarida qo‘llanuvchi elektromagnit tok o‘zgartkichlari nominaldan ancha katta toklarda, o‘tish rejimi sharoitlarida, masalan, qisqa tutashuv va shikastlanish hollarida o‘z funksiyalarini bajarishi shart.

В этой статье описывается управляемый преобразователь выходного напряжения в ток для контроля и управления реактивной мощностью асинхронного двигателя. Динамические характеристики преобразователя тока были получены с помощью программы Simulink с учетом надежности, чувствительности, точности измерения и погрешности. Преобразователи тока в основном эксплуатируются при нормальной устойчивой работе системы питания асинхронного двигателя. В этом режиме при исследовании преобразователей тока с некоторыми условными пределами принимаются минимальное и максимальное значения входного тока, для которых устанавливается класс точности (0,1‒1,2)∙Iном. Повреждение электрооборудования и сетей может привести к аварийному режиму работы системы электроснабжения асинхронного двигателя, в этом случае преобразователи тока работают в динамическом режиме. Короткие замыкания в асинхронном двигателе являются основной причиной работы электромагнитных преобразователей тока в динамических режимах. Условия работы адаптеров электромагнитного тока в таких режимах существенно отличаются от условий работы в цепях системы управления. Если для целей измерения используются адаптеры электромагнитного тока, то обычно требуется, чтобы они работали при первичном токе, не превышающем номинальный ток, и выполняли свои функции в случае повреждения.

This article uses a controlled output voltage-to-current converter to control the reactive power of an induction motor. The dynamic characteristics of the current converter were obtained using the Simulink program, taking into account reliability, sensitivity, measurement accuracy and error. Current converters are mainly operated during normal stable operation of the power supply system of an asynchronous motor. In this mode, when studying current transducers with certain conditional limits, the minimum and maximum values of the input current are accepted, for which the accuracy class (0.1‒1.2)∙Inom is set. Damage to electrical equipment and networks can lead to emergency operation of the power supply system of an asynchronous motor, in which case the current converters operate in dynamic mode. Short circuits in an asynchronous motor are the main reason for the operation of electromagnetic current converters in dynamic modes. The operating conditions of electromagnetic current adapters in such modes differ significantly from the operating conditions in the control system circuits. If electromagnetic current adapters are used for measurement purposes, they are usually required to operate at a primary current not exceeding the rated current and must perform their functions in the event of a fault.
