In a gas turbine system, what does Ngg stand for in fuel scheduling readings?

In the context of gas turbine systems, Ngg refers to "Net gas generator." This term is important because it represents the net output power produced by the gas generator section of the turbine, accounting for losses that occur within the system. Understanding the net gas generator allows technicians to assess the performance and efficiency of the gas turbine by evaluating how much of the generated power is available for use after considering operational losses, such as those from internal friction and auxiliary loads. This measurement is crucial for optimizing fuel scheduling and ensuring the turbine operates efficiently under varying loads and conditions.

Other terms, such as "gas generator gauge" or "normalized gas gauge," do not accurately describe the function of Ngg, while "next generator grade" does not pertain to the operational metrics commonly used in fuel scheduling or turbine performance assessment.
