Nor-Cal is responsible for the design and implementation of the following control algorithms for AEP’s 7FA units located at the Dresden and Waterford Energy Centers:

Isotherm Reduction- Developed sequencing that lowered Isotherm temperatures during start up, reducing thermal stresses to boiler tubes in HP and HRH section of HRSG due to overspaying of de-super heaters (attemperators).

Isochronous Control- Developed Isochronous/Island control for implementation on test units of the AEP GE 7FA fleet. The Isocronous (Island) control provides a dependable turbine/generator electrical supply for in- house loads.
