CPC Logic
One of the enhancements recently introduced is the Corrected Parameter Control logic (CPC).
This type of control philosophy applies principally to mechanical drive units, and consists of an
exhaust temperature control curve that self adjusts according to the condition of the inlet filters
and actual power turbine speed. This allows the engine to be operated at optimum conditions
not only at the nominal point, but over the entire operating envelop of inlet conditions and
power turbine speeds. The results of this improvement have already been proven in the field,
and are shown in the following figure (relating to the test of a GE10-2 unit at various free power
turbine speeds). Through the application of CPC logic it has been possible to significantly
increase the maximum output without compromising the safe operation of the unit by simply
optimizing its operation in real-time.
The variable free power turbine speed element of the CPC logic is a standard feature of MS5002D
DLN and MS5002E models, and all new GE10-2 units. The retrofit of existing gas turbine models
with this solution is also offered.
