Aspects of the invention relate to a system and method for operating a turbine engine assembly. The turbine engine assembly has a turbine engine having a compressor section, a combustor section and a turbine section. The combustor section has a lower T_PZ limit and the turbine engine has a design load. The assembly further includes at least one air bleed line from the compressor and at least one valve for controlling air flow through the bleed line. Control structure is provided for opening the valve to allow bleed air to flow through the bleed line when an operating load is less than the design load. The flow rate through the bleed line is increased as the operating load is decreased, reducing the power delivered by the turbine assembly while maintaining the T_PZ above a lower T_PZ limit. A method for operating a turbine engine assembly is also disclosed.

What is claimed is: 1. A turbine engine assembly for a generator, the assembly comprising:a turbine engine having a compressor section, a combustor section and a turbine section, the combustor section having a primary zone temperature and the turbine engine having a design load;at least one air bleed line in communication with the compressor section;at least one valve for controlling air flow through the at least one air bleed line;a plurality of inlet guide vanes in the compressor section;a controller that upon sensing a decreased operating load first closes the inlet guide vanes and then, in parallel, opens the at least one valve to allow bleed air to flow through the at least one air bleed line and opens the inlet guide vanes to increase compressor inlet flow when an operating load is less than the design load, wherein a flow rate through the at least one air bleed line is increased and compressor inlet flow is increased as the operating load is decreased thereby reducing power delivered to the generator while maintaining the primary zone temperature above a primary zone temperature lower limit, whereby additional inlet flow drawn into the compressor section is dumped out through the bleed line.
