Failure of induction motors, providing a complex continuous process, can lead to significant economic and environmental damage. Induction motors during voltage dips and interruptions can go into an unstable mode, which will cause a voltage collapse - destabilization of the electric load. In the study of the dynamic stability of asynchronous electric motors with adjustable frequency drives, we must take into account their special features.
The aim of this paper is to develop technical solutions to create a fault-tolerant power system of the motor load as an example of electric submersible pumps unit.
Ride-through solutions, we suggest, is to upgrade existing control stations (adjustable frequency drives) with systems of modern energy storage devices and their charge system, which can increase the stability of asynchronous motors with adjustable speed drives, including ESP unit, given their features. Other advantage of this ride-through solution is using of existing equipment. The paper describes the flywheel and capacitive (based on supercapacitors), energy storage, showing their possible inclusion in the electricity network of oil fields and ESP, and offer accommodation options in the area of electrical equipment.
