    Azizjan Abubakirov, Timur Kurbaniyazov, Muratbay Bekimbetov
    E3s Web of Conferences, 2024
    This article presents the principles of modeling three-phase asymmetrical currents in the form of secondary voltages of signal change sensors in the power supply system. The classical methods of signal transformation modeling do not provide the necessary accuracy due to the complexity in representing the interdependence between input and output quantities and parameters, as well as the difficulty in capturing the interchain dependencies and associated physical-technical effects. The analysis in this work focuses on the principles of signal transformation based on graph models, including the physical and technical effects of the three-phase primary current electromagnetic sensor that creates the interacting magnetic fields. The modifications to elements with nonlinear parameters and the values of the electric network currents in the power supply system during estimation have been considered as an object with concentrated parameters. In contrast to traditional single-phase current transformers, the complex transducing components, weight, and volume of the items are laborintensive when used in combined power measurement and control systems. They also do not provide the universality of the output value when interfacing with microprocessors and electronic technologies in intelligent systems.
  • Electromagnetic converter of reactive power and monitoring of high-voltage induction motors
    Azizjan Abubakirov, Naurizbek Eshmuratov, Gulayim Esemuratova, Muzaffar Nazarov
    E3s Web of Conferences, 2024
    In this paper, the control and monitoring of reactive power in an over-voltage induction motor are elucidated through a comparative analysis of theoretical and practical research findings. These results are based on structural principles, research models, and the static, dynamic, metrological, and technical characteristics of three-phase electromagnetic current converters, evaluated against established criteria. The effectiveness of employing current converters with straightforward design, high sensitivity, speed, and reliability, along with simple switching elements that transform the primary input stator current into a secondary voltage output signal, is emphasized. Utilizing a graph model, the static characteristics of the stator current to secondary voltage converter, essential for regulating and monitoring the reactive power of an asynchronous motor, are delineated, and a research algorithm is developed.

  • System for measuring and analysis of vibration in electric motors of irrigation facilities
    A Djalilov, O Matchonov, A Abubakirov, J Abdunabiev, A Saidov
    Iop Conference Series Earth and Environmental Science, 2021
    This article analyzes the vibration process that occurs in electric motors in irrigation facilities. It has been studied that various failures and electric motor imbalances and vibrations that can occur during the operation of electric motors at pumping stations have a negative impact on the whole system. Electrical and mechanical failures affect the normal operation of the electric motor, i.e. increase power consumption, increase current, increase heat, and also increase vibration. Balancing is an important requirement for electric motors and all rotating components. A modern SD-21 vibrodiagnostic device was used to detect vibration. The research was carried out using the method of comparing the trajectory obtained in the mode of synchronous accumulation using the vibrodiagnostic device SD-21. In the course of the research, the main factors that cause vibration in electric motors, the method of identification of decentralization that causes high vibration, the spectral and informative properties of vibrating signals were studied. The advantages of predicting the deviation of vibrations in electric motors from the allowable are highlighted. A virtual tool has been developed to detect and analyze vibration.
