Compressor start bleed system for a turbine system and method of controlling a compressor start bleed system

摘要

A compressor start bleed system for a turbine system includes a compressor section. Also included is a turbine section disposed downstream of the compressor section. Further included is at least one duct fluidly coupled to the compressor section, wherein the at least one duct is configured to route a start bleed extraction from the compressor section to a location downstream of the turbine section. Yet further included is at least one control device of the at least one duct configured to actively modulate the start bleed extraction during a part speed operation of the turbine system.

1. A method of controlling a compressor start bleed extraction during start-up operation of a turbine system having a compressor section, a turbine section and a combustor section, comprising:
monitoring at least one operating parameter of the turbine system; comparing the at least one operating parameter to a control schedule; routing a start bleed extraction through at least one duct from the compressor section to a location downstream of the turbine section; and: modulating the start bleed extraction through the at least one duct with at least one control device at least partially in response to the control schedule, wherein comparing the at least one operating parameter comprises comparing a compressor speed to a compressor operating limit line.
