Specific of ride through solutions for electric submerisible pumps with adjustable speed drive

Any interruption in the power supply can lead to significant environmental and economic damage. One of the most sensitive elements of the oil production (in terms of sensitivity to a power failure) are units with submersible electric submersible pumps (ESP), which is controlled most often by adjustable speed drive. In this paper discusses reasons of short-term power failure that can disrupt the stability of the dynamic stability, as well as suggested ride-through solutions for asynchronous motor with adjustable speed drive.
