Abstract
A method of engine electrical load shed control includes receiving an accessory load indicator corresponding to an accessory load of an engine. A request for acceleration of the engine is detected. One or more electrical buses are depowered based on the accessory load indicator exceeding a shedding threshold and detection of the request for acceleration of the engine.
Claims14
A method of engine electrical load shed control, the method comprising:
- monitoring an engine torque;
- receiving an accessory load indicator corresponding to an accessory load powered by an engine;
- detecting a request for acceleration of the engine;
- comparing the engine torque to a low engine power threshold;
- and
- depowering one or more electrical buses providing power to the accessory load to reduce a rotor droop associated with the acceleration of the engine based on detecting the request for acceleration of the engine when the engine torque is less than the low engine power threshold and the accessory load indicator exceeds a shedding threshold.
3 more elements
An engine control system comprising:
- a processor;
- and
- memory having instructions stored thereon that, when executed by the processor, cause the engine control system to:
- monitor an engine torque;
- receive an accessory load indicator corresponding to an accessory load powered by an engine;
- detect a request for acceleration of the engine;
- comparing the engine torque to a low engine power threshold;
- and
- reduce a rotor droop associated with the acceleration of the engine by depowering one or more electrical buses providing power to the accessory load based on detecting the request for acceleration when the engine torque is less than the low engine power threshold and the accessory load indicator exceeds a shedding threshold.
