Abstract
An electric power generation system is described can include a variable speed generator and an engine driving the generator to provide an AC electric power output. The output is monitored for different types of transient conditions. For example, electric current of the output is evaluated to identify a first type of transient condition and power factor of the output is evaluated to identify a second type of transient condition. System adjustment is made based on the condition type. In one form, the system is used to provide electricity on board a vehicle such as a motor coach, ship, or the like. In other forms, the system provides electric power to a remote building that does not have access to a public power grid or the system provides back-up power in case of power grid failure or the like.
