Method, apparatus, signals and media, for selecting operating conditions of a genset
First Claim
1. A method for selecting operating conditions of a genset comprising an engine coupled to an electrical power generator, the genset having a plurality of operating points each comprising an engine speed value and a generator electrical power output value, the method comprising:
- determining a plurality of cost values corresponding to respective ones of the operating points,selecting a set of operating points from the plurality of operating points such that;
a sum of the cost values corresponding to the operating points in the selected set is minimized; and
the engine speed values of the operating points in the selected set increase or decrease as a function of the generator electrical power output values of the operating points in the selected set;
wherein the sum of the cost values corresponding to the operating points in the selected set is determined by assigning a weight to one or more of the operating points in the selected set, and wherein greater weights are assigned to operating points having electrical output values proximate a midpoint of a range of power outputs that the electrical power generator is capable of supplying.
