SYSTEMS AND METHODS FOR TURBINE SYSTEM OPERATION IN LOW AMBIENT TEMPERATURES

摘要

A system includes a controller communicatively coupled to a compressor (26). The controller is configured to sense an exhaust temperature of a gas turbine system (24) fluidly coupled to the compressor (26) and derive a setpoint based on the sensed exhaust temperature. The controller is also configured to actuate an inlet bleed heat valve (74) based on the derived setpoint and an ambient temperature. The inlet bleed heat valve (74) directs a compressor fluid from the compressor (26) into a fluid intake system (18) fluidly coupled to the compressor (26) upstream of the compressor (26) and configured to intake a fluid.
