Downhole power generation system with alternate flow paths
First Claim
1. A downhole power generation system, comprising:
- a tubular power generation device configured to be disposed in an annular space around a portion of a production tubing, wherein the power generation device is switchable between a power generation mode and a bypass mode, the power generation device comprising;
a power generation path configured to receive a flow of fluid therethrough during the power generation mode,a turbomachinery system comprising a rotor disposed within the power generation path, the rotor comprising a rotor hub and a plurality of rotor blades extending from the rotor hub, wherein the rotor rotates when the flow of fluid traverses the power generation path,a bypass path configured to receive the flow of fluid therethrough during the bypass mode;
a power generation port coupled to the power generation path through which fluid enters the power generation path;
a bypass port coupled to the bypass path through which fluid enters the bypass path; and
a power generation unit coupled to the turbomachinery system and configured to convert rotation of the rotor into electricity.

Abstract
A downhole power generation device includes a tubular housing configured to be disposed within an annular space and around a portion of production tubing. The housing includes a flow compartment configured to receive a flow of fluid therethrough when the power generation device is in a power generation mode, and an electronics compartment comprising a controller and a power generation unit. The downhole power generation device further includes a turbomachinery system comprising a rotor disposed within the flow compartment and comprising a rotor hub and a plurality of rotor blades, wherein the rotor rotates when the flow of fluid traverses the flow compartment. The downhole power generation device also includes a port coupled to the flow compartment, through which fluid enters the flow compartment.
