CONTROL SYSTEM
First Claim
1. An improved control system for use in a subterranean well, the system comprising:
- at least one apparatus positioned within the subterranean well;
at least one power generation device positioned within the subterranean well, the at least one power generation device adapted to supply electrical power to the at least one apparatus; and
at least one control line positioned in the subterranean well, the at least one control line adapted to supply a hydraulic pressure applied from surface to the at least one power generation device from which the at least one power generation device generates electrical power.

Abstract
An improved control system for use in a subterranean well is described. The system comprises at least one apparatus positioned within the subterranean well, at least one power generation device positioned within the subterranean well, the at least one power generation device adapted to supply electrical power to the at least one apparatus and at least one control line positioned in the subterranean well. The at least one control line is adapted to supply a hydraulic pressure applied from surface to the at least one power generation device from which the at least one power generation device generates electrical power.

- 15. The improved control system of 7, wherein where the/each power generation device converts the applied hydraulic pressure in to linear motion using a piston, the piston is moveable between a first position and a second position and comprises a biasing means to bias the piston to the first position.

20. A method of controlling at least one apparatus positioned within a subterranean well, the method comprising the steps of:
applying a hydraulic pressure from surface to a power generation device, the power generation device adapted to convert the applied force into electrical energy, the electrical energy being used to control at least one apparatus positioned within the subterranean well.
