Wind turbine cable twist prevention

The inventions concerns a cable comprising a cable jacket and at least two medium voltage wires disposed within the cable jacket for transporting medium voltage current and at least two low voltage wires disposed within the cable jacket for transporting a low voltage current. Further, it concerns a wind turbine having a generator for generating electricity, wherein the generator being electrically connected to at least two medium voltage wires for feeding the generated electricity into a grid, the wind turbine having further a low voltage network for providing low voltage power to low voltage consumers, the low voltage network being electrically connected to a low voltage cable, wherein the low voltage cable and the medium voltage wires are accommodated in a common cable jacket. Finally it concerns a wind park comprising at least two wind turbines, each of the wind turbines having a generator for generating electricity, wherein the generator being electrically connected to at least two medium voltage wires for feeding generated medium voltage current to a grid, the wind turbines having further a low voltage network for providing low voltage power to low voltage consumers of the wind turbine, the low voltage network being electrically connected to a low voltage cable, wherein the low voltage cable and the medium voltage wires are accommodated in a common cable jacket.

Power backup system for offshore wind generators

A power generation system and a method for storing electrical energy are provided. The method includes generating a first AC voltage from a wind turbine generator and converting the first AC voltage to a first DC voltage, utilizing a rectifier. The method further includes routing the first DC voltage through a DC voltage bus to an inverter of the power converter, and converting the first DC voltage to a second AC voltage utilizing the inverter and outputting the second AC voltage to an electrical grid in response to a first control signal from a power converter controller. The method further includes receiving the first DC voltage from the DC voltage bus at a DC-DC converter operably coupled to the DC voltage bus, and storing electrical energy from the first DC voltage in a battery storage unit utilizing the DC-DC converter in response to a second control signal.
