Embodiment Construction

[0056] figure 1 is a perspective view of a wind turbine arrangement 1 according to a first embodiment of the invention. The wind turbine arrangement 1 comprises a main wind turbine 2 comprising a tower 3 and a nacelle 4 carrying a rotor with three wind turbine blades 5 . The tower 3 of the master wind turbine 2 is mounted on a platform 6 on which are also mounted four slave wind turbines 7a, 7b, three of which are visible. The two slave wind turbines 7a are horizontal axis wind turbines (HAWT) and the two slave wind turbines 7b (one of which is visible) are vertical axis wind turbines (VAWT). The platform 6 is arranged on an offshore foundation 8 . Thus, the wind turbine installation 1 is arranged offshore.

[0057] The main wind turbine 2 is adapted to generate electrical energy to the grid. The slave wind turbines 7a, 7b are disconnected from the grid. Instead, the electrical energy generated by the slave wind turbines 7a, 7b is fed to one or more internal power consumi...

Abstract

A wind turbine arrangement comprises a main wind turbine and at least one secondary wind turbine. The main wind turbine is arranged to produce electrical power and to supply produced electrical power to an external power recipient, such as a power grid. The main wind turbine comprises one or more power consuming internal systems, e.g., yaw system, control system, heating systems, lubrication systems, etc. The secondary wind turbine (s) is / are arranged to produce electrical power and to supply produced electrical power to at least some of the power consuming internal system(s) of the main wind turbine. The secondary wind turbine(s) is / are electrically disconnected from the external power recipient. The secondary wind turbine(s) may constitute a backup power supply to the internal systems. Thereby it is not necessary to refuel the backup power supply, and the backup power supply is environmental friendly. This is particularly useful in offshore wind turbine arrangements.

Description

technical field [0001] The invention relates to a wind turbine arrangement comprising a master wind turbine arranged to generate electrical energy for an external electrical energy receiver, such as a grid, and at least one slave wind turbine arranged To generate electrical energy for one or more internal power consumption systems of the main wind turbine. The secondary wind turbine preferably acts as a backup power supply for supplying at least some of the internal power consuming systems of the main wind turbine in case the main power supply for the internal power consuming systems fails or is interrupted. The wind turbine installation of the invention is particularly suitable for use in offshore wind power installations. Background technique [0002] Several internal power consumption systems are required in modern wind turbines in order to guarantee correct and safe operation of the wind turbine. Such systems include, but are not limited to: yaw systems, which are used...
