Power system having transient control
First Claim
1. A power system, comprising:
- an engine having a desired speed range;
a generator mechanically driven by the engine to produce electrical power directed to an external load;
a power storage device associated with at least one of the engine and the generator; and
a controller in communication with the engine and the power storage device, the controller being configured to;
determine a speed of the engine deviating from the desired speed range; and
activate the power storage device to absorb or supplement at least a portion of the electrical power directed to the external load based on the determination.

Abstract
A power system is disclosed. The power system may have an engine with a desired operating speed range, and a generator mechanically driven by the engine to produce electrical power directed to an external load. The power system may also have a power storage device associated with at least one of the engine and the generator, and a controller in communication with the engine and the power storage device. The controller may be configured to determine a speed of the engine deviating from the desired operating range, and to activate the power storage device to absorb or supplement at least a portion of the electrical power directed to the external load based on the determination.

13. A power system, comprising:
-
a generator set having a desired operating range and being configured to supply electrical power to an external load; a power storage device associated with the generator set; and a controller in communication with the generator set and the power storage device, the controller being configured to; determine a change in the external load; and activate the power storage device to absorb or supplement at least a portion of the electrical power supplied to the external load when the change in the external load will cause operation of the generator set to deviate from the desired operating range. - View Dependent Claims (14, 15)

16. A method of operating a generator set, comprising:
-
combusting a mixture of fuel and air to generate electrical power; directing the electrical power to an external load; determining an engine speed of the generator set; comparing the engine speed to a desired engine speed; and absorbing or supplementing at least a portion of the electrical power directed to the external load based on the comparison. - View Dependent Claims (17, 18, 19, 20)
