description: The topic of this master's thesis is "Investigation of the dynamic stability of the motor load of an oil refinery."This work is devoted to the study of the possibility of maintaining the dynamic stability of synchronous motors and ensuring self-starting of asynchronous motors in the event of disturbances.In the course of the work, the following tasks were solved:1) The origins of the problems of instability of power supply systems have been studied;2) Refreshed in the memory of theoretical information about the concept of sustainability of energy systems and power supply systems;3) The description of the studied power supply system of the oil and gas complex was completed;4) The parameters of synchronous and asynchronous motors were calculated and set in the Mustang software and computer complex;5) Calculations of dynamic stability were carried out in the event of an interruption in the power supply of the motor and in the event of a three-phase short circuit near the connection of the motor load;6) Measures are proposed to improve the dynamic stability of the studied power supply system of the oil pumping station of Gazpromneft-MNPZ JSC.The analysis of the dynamic stability of synchronous motors and self-starting of asynchronous motors was carried out on the basis of calculations carried out in the Mustang software-computer complex, designed for the prompt execution of calculations of steady-state and transient modes of electrical systems.As measures to improve the dynamic stability of the considered power supply system, the following were proposed:â¢ Using the automatic input of the back-up switch;â¢ Shutdown of a part of irresponsible motor load;â¢ Installation of capacitor banks in order to balance the consumption and generation of reactive power in the power supply system.Based on the results of the work performed, recommendations are proposed for taking measures to improve the dynamic stability of this power supply system.77 pages, 9 tables, 124 figures, 1 appendix.
