Abstract
A power generating unit, control unit and modular power generating system. A power generating unit includes an engine-generator set including an engine that produces mechanical power and a generator mechanically coupled to the engine. The generator converts the mechanical power to electrical power provided to a DC link. The control unit includes at least one controller configured to control fuel flow to the engine based on a voltage of the DC link.
Claims20
A power generating unit, comprising:
- an engine-generator set, comprising:
- an engine that produces mechanical power;
- and
- a generator coupled to the engine, wherein the generator receives the mechanical power from the engine and converts the mechanical power to a first form of electrical power;
- a first power converter that receives the first form of electrical power from the generator and converts the first form of electrical power to a second form of electrical power;
- a DC link that receives the second form of electrical power from the first power converter;
- an energy storage unit that receives the second form of electrical power from the DC link;
- and
- at least one controller configured to control fuel flow to the engine based on a voltage of the DC link.
A control unit for a power generating unit comprising an engine-generator set including an engine that produces mechanical power and a generator mechanically coupled to the engine, wherein the generator converts the mechanical power to electrical power provided to a DC link, the control unit comprising:
- at least one controller configured to control fuel flow to the engine based on a voltage of the DC link.
A modular power generating system, comprising:
- two or more engine-generator sets units each producing a first form of electrical power;
- first power converters comprising a first power converter for each engine-generator set, each configured to receive a first form of electrical power from its corresponding engine-generator set, and convert the first form of electrical power to a second form of electrical power;
- a DC link that receives the second form of electrical power from the first power converters;
- an energy storage unit that receives the second form of electrical power from the DC link;
- and
- at least one controller configured to control fuel flow to each engine-generator set based on the voltage of the DC link.
The modular power generating system of 15, further comprising one or more power delivery units, each configured to receive the second form of electrical power from the DC link, convert the second form of electrical power to a third form of electrical power, and provide the third form of electrical power as the one or more outputs of the modular power generating system.
