System and method for gas turbine chilled water storage discharge control and/or gas turbine output control

摘要

Variable speed drive controlled discharge pumps are used for pumping chilled water from a chilled water storage tank to coils operatively associated with the air inlet of a gas turbine, wherein the gas turbine is used to generate electricity. Use of the variable speed drive controlled discharge pumps aids is protecting the temperature distribution in the chilled water storage tank so that a thermocline rises with the addition of chilled water during charging of the tank with chilled water, and lowers during discharge of the tank when using the chilled water to cool inlet air at one or more gas turbines operated at a facility.

主权项

1. A method for maintaining a thermocline within a chilled water storage tank of a gas turbine electrical generation plant, the method comprising:
providing said chilled water storage tank with temperature sensors; monitoring with a computer information gathered from said chilled water storage tank temperature sensors; discharging cold water from the chilled water storage tank using a discharge pump controlled by a first variable speed drive control using said information gathered from said chilled water storage tank temperature sensors; wherein the cold water is pumped by the discharge pump to a coil within an air inlet of a gas turbine.
