| description | Relevance of the study is caused by the necessity of developing induction motor electric drives of well logging truck hoist for visual monitoring the borehole operating conditions. The main aim of the study is to develop and research the scalar control system for electric drive comprised of frequency converter and induction motor. The system should take into account operation features and the load parameter changes in the hoist for geophysical research of boreholes. Methods of research are based on application of automatic control theory and simulation modeling under MatLab-Simulink environment. Results. The authors have developed the load computation method for lowering and hoisting the downhole instrument, which allows determining the power of the electric drive of the hoisting mechanism more accurately. Variable-speed electric drive comprised of frequency converter and induction motor with scalar control system were developed for geophysical hoists. The transients for all operating modes of electric drive of the well logging truck hoist were calculated, including sticking of the geophysical instrument in the borehole. The obtained results of the studies were validated by the experimental results of the developed electric drive of hoisting mechanisms for geophysical research of boreholes. Findings. When studying the variable-speed induction motor drive with scalar control system, one should take into account the peculiarities of the PWM voltage control in the frequency converter. This allows achieving more reliable results of simulation modeling and accelerating the controllers tuning of electric drives of truck hoist. It was ascertained that the current degenerative feedback with delay in control channel of voltage and frequency limits a root-mean-square value of stator current of the variable-frequency induction motor in all normal and emergency operating modes of the truck hoist. It was ascertained as well that in all operating modes of the truck hoist the load on the motor shaft is active, therefore, while lowering the downhole instrument the induction motor operates in generator mode with power dissipation in brake resistors of the frequency converter. If the lowering of the downhole instrument lasts for a long time, than the brake resistors should have increased power ratings. |
