Abstract

This work discloses an ocean current power generation system. The ocean current power generation system includes at least two ocean current generators, a first transformer, a first filter, a first AC / DC converter, a DC bus, at least one energy storage device, a DC / DC converter, a DC reactor, at least one power grid, a second DC / AC converter, a second filter, and a second transformer. The ocean current power generation system is used to balance the power generated by the ocean current generators.

Claims

1. An ocean current power generation system, comprising: at least two ocean current generators; a first transformer connected to each of the at least two ocean current generators; a first filter connected to the first transformer; a first AC / DC converter connected to the first filter; a DC bus connected to the first AC / DC converter; at least one energy storage device, each of the at least one energy storage device being sequentially connected to the DC bus via a DC reactor and a DC / DC converter; and at least one power grid, each of the at least one power grid being sequentially connected to the DC bus via a second transformer, a second filter, and a second DC / AC converter.

2. The ocean current power generation system as described in claim 1, wherein the first transformer is a rectifier.

3. The ocean current power generation system as described in claim 1, wherein the first filter is an LC filter.

4. The ocean current power generation system as described in claim 1, wherein the energy storage device is a battery.

5. The ocean current power generation system as described in claim 4, wherein the type of battery includes lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, or lithium-ion batteries.

6. The ocean current power generation system as described in claim 1, wherein the second transformer is a rectifier.

7. The ocean current power generation system as described in claim 1, wherein the second filter is an LC filter.

8. The ocean current power generation system as described in claim 1, wherein the DC reactor is a filtered DC reactor.

9. The ocean current power generation system as described in claim 1, wherein a switch is further provided between the second transformer and the power grid.

10. The ocean current power generation system as described in claim 1, wherein the power grid is a smart grid.
