摘要： A method for preventing damage to a downhole pump impeller of a downhole pump includes setting a rotatable part of a downhole pump to a selected depth, monitoring the depth of the rotatable part, determining that the depth of the rotatable part has significantly changed, and taking a corrective action to return the depth of the rotatable part to said selected depth in order to prevent damage to an impeller that is liable to be caused by a change in depth of the rotatable part. The downhole pump further has a line shaft, an impeller engaged with the line shaft for pressurizing fluid to be extracted from a well, and monitoring apparatus for monitoring the depth of a distal end of the line shaft in order to prevent damage to the impeller that is liable to be caused by a change in depth of the distal end.

A primary steam turbine in the high pressure steam channel is responsive to high pressure steam for generating electricity and producing heat depleted high pressure steam. A secondary separator separates the heat depleted high pressure steam into a steam component and a liquid component. A primary heat exchanger is responsive to the high pressure liquid and the steam component for transferring heat to said steam component thereby producing low pressure steam and cooled high pressure liquid. At least one power plant module includes a low pressure steam turbine responsive to the low pressure steam for producing electricity and heat depleted low pressure steam; a condenser/vaporizer containing an organic fluid for receiving the heat depleted low pressure steam and converting it into condensate, and for vaporizing the organic fluid; an organic vapor turbine responsive to vaporized organic fluid produced by the condenser/vaporizer for generating electricity and for producing heat depleted organic fluid; a condenser for condensing the heat depleted organic vapor into a liquid; a preheater for heating the liquid; a pump for returning heated liquid from the preheater to the condenser/vaporizer; and a conduit for directing condensate from the condenser to the preheater.
