System and method for controlling power output of a power source

A control system for a generator set comprising an engine and a generator coupled to the engine, the control system comprising:

• a first sensor module configured to generate signals indicative of an ambient condition of the generator set;
• a second sensor module configured to generate signals indicative of an operating parameter of the engine;
• and
• a controller communicably coupled to the first sensor module and the second sensor module, the controller configured to:
• receive signals indicative of the ambient condition of the generator set and the operating parameter of the engine;
• determine a first power output based on the ambient condition of the generator set and a second power output based on the operating parameter of the engine;
• determine a first de-rate value based on the first power output and a predetermined power output of the engine;
• determine a second de-rate value based on the second power output and the predetermined power output of the engine;
• determine a final de-rate value based on the first de-rate value and the second de-rate value, wherein the final de-rate value is a minimum value of the first de-rate value and the second de-rate value;
• and
• control the generator to regulate a power output of the generator set based on the final de-rate value.

A method of controlling a power output of a power source, the power source comprises an engine and a power conversion device drivably coupled to the engine, the method comprising:

• determining an ambient condition of the power source and an operating parameter of the engine;
• determining a first power output based on the ambient condition of the power source and a second power output based on the operating parameter of the engine;
• determining a final power output based on the first power output and the second power output, wherein the final power output is a minimum value of the first power output and the second power output;
• comparing the final power output with a predetermined power output of the engine;
• and
• controlling the power conversion device to regulate the power output of the power source based on the comparison between the final power output and the predetermined power output.
