Systems and methods for adjusting operations of a gas turbine following a transient event

A method, comprising:

• monitoring a first set of electrical properties associated with an electrical grid configured to couple to a generator;
• determining whether a transient event is present on the electrical grid based on the first set of electrical properties;
• determining a mechanical power present on a shaft in the generator based on a second set of electrical properties associated with the generator in response to the transient event being present, wherein the second set of electrical properties comprises an inertia on the shaft in the generator, an accelerating power associated with a rotor of a turbine, and a power output by the generator, and wherein the mechanical power comprises an indication of energy used to rotate the shaft;
• and
• sending the mechanical power to a controller associated with the turbine configured to couple to the generator, wherein the controller is configured to adjust one or more operations of the turbine based on the mechanical power.

A non-transitory computer readable medium comprising computer-executable instructions configured to cause a processor to:

• monitor a first set of electrical properties associated with an electrical grid configured to couple to a generator;
• determine whether a transient event is present on the electrical grid based on the first set of electrical properties;
• determine a mechanical power present on a shaft of the generator based on a second set of electrical properties associated with the generator, the electrical grid, or both when the transient event is present, wherein the second set of electrical properties comprises a power output of the generator and an accelerating power associated with a rotor of a turbine, wherein the mechanical power comprises an indication of energy used to rotate the shaft;
• and
• send the mechanical power to a controller associated with the turbine configured to couple to the generator, wherein the controller is configured to adjust one or more operations of the turbine based on the mechanical power, wherein the one or more operations of the turbine comprise a Dry Low NOx (DLN) mode of the turbine.
