Abstract

A process for controlling a system for generating electricity which contains at least two compressors and two microturbines. Compressed gas from a pressure vessel is supplied to the first microturbine, and thereafter the pressure within the pressure vessel is measured. If the pressure is below a specified value, a first compressor is caused to operate to feed compressed gas to the pressure vessel. Thereafter, as the system needs require, a second compressor and, optionally, a third compressor is caused to furnish compressed gas to the pressure vessel. If the system pressure within the pressure vessel is too high, the third compressor is shut down and, if necessary, the second compressor and the first compressor are then sequentially shut down.

Dependent claims

A process for controlling a system for generating electricity, which system is comprised of a first compressor, a second compressor, a first microturbine, and a second microturbine, comprising the steps of:

(a) supplying a first compressed gas at a pressure of from about 40 to about 500 pounds per square inch from a first gas source to said first microturbine,
(b) making a first measurement of the pressure of gas within said first gas source,
(c) supplying gas from a second gas source to said first compressor,
(d) compressing said gas from said second gas source in said first compressor to a pressure of from about 40 to about 500 pounds per square inch, thereby producing a second compressed gas,
(f) supplying said second compressed gas to said first gas source,
(g) supplying said second compressed gas from said first gas source to said first microturbine,
(h) making a second measurement of the pressure of gas within said first gas source,
(i) supplying gas from a second gas source to a second compressor,
(j) compressing said gas from said second gas source in said second compressor to a pressure of from about 40 to about 500 pounds per square inch, thereby producing a third compressed gas,
(k) supplying said third compressed gas to said first gas source, and
(l) supplying said third compressed gas from said first gas source to said second microturbine.
