Abstract
A power system has a generator, a variable load, and an electrical accumulator unit. The electrical accumulator unit stores power when the generator generates excess power, and supplements power from the generator when the generator generates insufficient power.
Claims24
A power generation system comprising:
- a generator;
- a controller coupled to said generator such that said controller can control a power output of said generator;
- a power bus connected to said generator such that said power bus receives electrical power from said generator;
- and
- an electrical accumulator unit connected to said power bus such that said electrical accumulator unit is capable of storing power from said power bus and providing power to said power bus, said electrical accumulator unit further comprising an independent electrical accumulator unit controller, wherein said independent electrical accumulator unit controller comprises at least a first load-balancing sink mode and a second load-balancing source mode.

A method for operating a power system comprising the steps of:
- converting power from a generator into DC power format;
- providing said DC power to a power bus;
- detecting a power characteristic on said power bus using a sensor;
- operating a connected electrical accumulator unit in at least one of a load-balancing sink mode, a load-balancing source mode, a maintenance mode and a stand-by mode, wherein said mode is determined at least in part based on said detected power characteristic;
- placing said electrical accumulator unit in a load balancing sink mode when said detected power characteristic exceeds a first threshold;
- operating said electrical accumulator unit as a power bus voltage regulator while in said load balancing sink mode;
- and
- controlling said connected electrical accumulator unit using an independent electrical accumulator unit controller.
