Title:
VARIABLE SPEED HIGH EFFICIENCY GAS COMPRESSOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/159463
Kind Code:
A3
Abstract:
A system for powering a compressor. The system may include a power generation unit adapted to generate AC power. An electric motor may be coupled to the power generation unit and adapted to turn at a rate proportionate to a frequency of the AC power. A compressor may be coupled to the electric motor, and an output pressure of the compressor may be directly dependent on the rate that the electric motor turns. A control system may be coupled to the power generation unit and to the compressor, and the control system may be adapted to vary the frequency of the AC power generated by the power generation unit, thereby varying the output pressure of the compressor.
