Offshore wind turbine installation system and method

Номер: US20120000071A1
Автор: Peter Graham Harris
Принадлежит: Technip France SAS

The disclosure provides a method and system for installing components for an offshore wind turbine assembly independent of cranes and derricks. The components are stored in an offshore structure, such as a Spar. After transporting the offshore structure horizontally to a site, the structure can be uprighted to a vertical orientation. A variable ballast component coupled to a tower of the wind turbine assembly can reciprocally retract the tower into the offshore structure to lower the tower, and extend the tower away from the offshore structure to raise the tower until the full quantity of blades are assembled to a turbine coupled to the tower. When the blades are stored in a peripheral fashion around the tower, the method and system provides for automatic rotational indexing of the tower as the tower and turbine retract and extend, so the turbine is progressively aligned with each blade to be installed.

Method of maintaining hydraulic pump in a renewable energy turbine generator

Номер: US20130216403A1
Автор: Alasdair Robertson, Henry Dodson, Robert Fox, Stephen Salter, Tom Mcgrath, Uwe Stein
Принадлежит: Mitsubishi Heavy Industries Ltd

A hydraulic pump comprises ( 1 ) an outward ring ( 24 ), including demountable blocks ( 30 ) comprising piston cylinders ( 32 ), and an inward ring ( 21 ), comprising a ring cam ( 23 ), coupled through a drive shaft ( 8 ) to the blades of a turbine ( 4 ). To enable maintenance, the outward ring is decoupled from a torque limiting device ( 16, 17 ) and rotated relative to the inward ring. Demountable blocks are then removed from the outward ring using a crane ( 61 ) including a line ( 62 ) extending from above the centre of mass of the demountable block and including a resilient portion ( 66 ) so that although the crane supplies the majority of the force required to remove the demountable block, an operator provides some force, enabling the process to be controlled. The method is suitable for maintaining large hydraulic pumps in wind turbine nacelles ( 2 ).

The invention relates to the technical field of operation and maintenance of wind turbines, and is also applicable to non-destructive measurement of a depth of a defect of other resin-based composite materials. It is aimed at the problem that the depth of the defect cannot be determined by an intuitive infrared thermal image in the measurement of a depth of a defect of a large wind turbine blade. This method not only ensures accuracy of the measurement, but can also be widely applied. The method comprises the following steps: S1: continuously heating a surface of a wind turbine blade with an irradiation heat source; S2: collecting and storing a real-time heat map sequence of a surface of the blade with an NEC R300 infrared thermal imaging camera; S3: extracting a surface temperature rise curve at a defect location and organizing the results into a temperature rise curve family of the layers in a depth direction at the defect location; S4: extracting a surface temperature rise curve at a non-defect location, and calculating the similarity between the two temperature rise curve families; S5-S7: obtaining a reference depth value of the defect; and S8: determining whether the depth value is in a characteristic interval. 2.

A method for protecting personnel working in a wind turbine nacelle or hub includes monitoring a nacelle roof hatch and a hub access hatch, each hatch having a switch configured therewith. When at least one of the hatches is detected as opened, a control system detects if a rotor lock has been engaged. If the rotor lock has not been engaged, the control system triggers a rotor brake to stop rotor and drivetrain component rotational movement and actuates a first control lockout between the respective switch configured with the open hatch and the rotor brake. The control system also initiates a control lockout that prevents release of the rotor brake until the switch indicates that the open hatch has been closed and the first control lockout has been reset.

Wind turbine and method of generating power from the wind

Номер: US20210095638A1
Автор: Osama Elogab, Zachary Elogab
Принадлежит: Ogab Ltd

The blades of conventional wind turbines almost always have adjustable pitch; that is, they can be pivoted about their length in order to change the angle of attack of the blades to the wind. This is necessary, because the effective angle of attack varies with both wind speed and rotational speed. In particular, in extremely high wind speeds, the blades can be ‘feathered’ to reduce the amount of torque being imparted to the turbine. The present invention provides a wind turbine in which pressurised air may be conveyed to air outlets 21 on the blades 1 . In this way, the aerodynamic behaviour of the blade 1 may be controlled, effectively feathering the blade without needing a robust mechanical system for pivoting the blade.
