Abstract
A control system for a base load output of a gas turbine engine. The control system may include an inlet chilling coil system for providing air to the gas turbine engine at a desired temperature, a temperature control valve in communication with the inlet chilling coil system, a temperature sensor positioned about the gas turbine engine, and a temperature controller in communication with the temperature control valve and the temperature sensor. The temperature controller modulates the temperature control valve until the air provided to the gas turbine engine by the inlet chilling coil system reaches the desired temperature as sensed by the temperature sensor.

A control system for a base load output of a gas turbine engine, comprising:
- an inlet chilling coil system for providing air to the gas turbine engine at a desired temperature;
- a temperature control valve in communication with the inlet chilling coil system;
- a temperature sensor positioned about the gas turbine engine;
- and
- a temperature controller in communication with the temperature control valve and the temperature sensor;
- wherein the temperature controller modulates the temperature control valve until the air provided to the gas turbine engine by the inlet chilling coil system reaches the desired temperature as sensed by the temperature sensor.
A method of reducing the output of a gas turbine engine having an inlet chilling system to a desired base load, comprising:
- modulating the angle of a plurality of inlet guide vanes until the angle reaches a predetermined angle;
- maintaining the angle of the plurality of inlet guide vanes at the predetermined angle;
- modulating a flow of water through the inlet chilling system until an output temperature reaches a predetermined temperature;
- turning the inlet chilling system off;
- and
- modulating the angle of the plurality of inlet guide vanes until the desired base load is reached.
A gas turbine system, comprising:
- a compressor;
- a control system for modulating a base load output of the gas turbine system;
- the control system comprising a temperature sensor positioned about the compressor;
- and
- an inlet chilling coil system for providing air to the compressor at a desired temperature;
- the inlet chilling coil system comprising a temperature control valve in communication with the control system such that the control system modulates the temperature control valve until the air provided to the compressor by the inlet chilling coil system reaches the desired temperature as sensed by the temperature sensor.
