Abstract
A well system includes an electrical submersible pumping ('ESP') assembly, a variable speed drive, and a ride through system. The ESP assembly includes a pump for lifting liquid from inside the well and an electric motor for powering the pump. The variable speed drive is outside the well and controls delivery of electricity from a power source to the motor. The ride through system provides backup electricity if there is an interruption of electricity from the power source. The ride through system includes a bank of power modules having stored electrical power. The modules are connected in series and have a combined electrical potential adequate for powering the motor. By selectively disconnecting adjacent modules from one another, the electrical potential from the bank of power modules is reduced to a magnitude that is not hazardous for personnel.
