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.

Мачта ветрогенератора модульного типа

Номер: RU0000196874U1
Автор: Сергей Викторович Михалап
Принадлежит: Общество с ограниченной ответственностью "Бизнес Энерджи"

Полезная модель относится к ветроэнергетике, а именно к ветродвигателям роторного типа с вертикальным валом вращения и может быть использована в электромашиностроении.Задача, на решение которой направлена заявленная модель, заключается в создании модульной мачты, прочной по своей конструкции и, кроме того, удобной для ремонта, монтажа, обслуживания, а также транспортировки.Техническое решение заключается в создании мачты модульного типа, где мачта поделена на несколько модулей: модуль с генератором и модули с лопастями. При сборке модулей образуется внешний каркас, который несет основную нагрузку.Техническим результатом является создание конструкции мачты, совмещающей в себе требования к прочности за счет внешнего каркаса, а также удобства для ремонта, обслуживания и транспортировки, с возможностью изменения мощности генератора, за счет того, что мачта состоит из модулей.Мачта модульного типа состоит минимум из двух модулей, соединенных между собой. Основанием мачты служит модуль генератора. Модуль генератора крепится на грунт, бетонное основание или крышу здания. На модуль генератора сверху устанавливается модуль ветроуловителя (модуль с лопастями). Монтаж происходит таким образом, что выходной вал ветроуловителя соединяется с помощью муфты для передачи момента. Крепление силовых рам модулей болтовое. При необходимости можно поставить еще один или несколько модулей с лопастями, которые соединяются между собой аналогичным образом.

A wind turbine utilizes a rotor assembly rotating about a substantially horizontal shaft, wherein said rotational motion is converted to a substantially vertical rotational motion through a shaft extending down from the nacelle located near the top of the tower structure to a mechanical room located at a lower altitude relative to the top of the tower. Said lower mechanical room houses some of the large heavy operational components of the turbine such that the turbine is not as top heavy as conventional turbines, and maintenance of the turbine is improved through ease of access to the lower altitude mechanical room.

Method for Erecting a Wind Turbine Tower

Номер: US20120304588A1
Автор: Patrik Von Ahn
Принадлежит: Individual

The present invention concerns a wind turbine ( 1 ) including at least one tower ( 2 ), at least one base foundation ( 3 ), at least one nacelle ( 10 ) and at least one propeller ( 4 ). The propeller via its rotation turns at least one essentially horizontal axel that drives at least one generator. The wind turbine's uniqueness comes from its tower ( 2 ), via at least one bearing ( 7 ), being pivotally arranged around an axis of rotation in the tower's ( 2 ) axial direction. The present invention also concerns a method for erecting the wind turbine's tower ( 2 ). Unique to the method for erecting the tower is that the tower is joined together by sections ( 11 ), comprised of at least one first mantle plate ( 12 ) and at least one second mantle plate ( 13 ), which are sequentially assembled at the erection site on the tower's lower end ( 6 ). When the mantle plates ( 12, 13 ) in a section ( 11 ) are joined together with each other, the section ( 11 ) is then united with previously joined sections ( 11 ) in the tower's lower end ( 6 ). After each respective section ( 11 ) is joined with the tower's ( 2 ) previously united sections ( 11 ), the tower ( 2 ) is erected in the vertical direction with at least one, and preferably several, lifting bodies ( 18 ). After the required height of the tower is obtained, the tower, alternatively the tower's upper part, is secured to a bearing ( 7 ) or alternatively to an intermediate part or several intermediate parts connected to the bearing ( 7 ).

A wind power generation apparatus includes a wind collecting hood, a rotary shaft, a rotary structure and a wind guiding structure. The wind collecting hood is a hollow circular barrel to form an airflow passage. The rotary shaft is located in the airflow passage of the wind collecting hood. The rotary structure is mounted onto the rotary shaft. The wind guiding structure is fastened to the wind collecting hood and located at the front end of the rotary structure. The wind guiding structure directs direction of airflow and accelerates the airflow to become swirling airflow to directly blow the rotary structure at optimal angles, thus capability of driving the rotary structure to rotate by wind is increased and starting wind power of the rotary structure is reduced. The rotary structure is still rotated at where the wind is smaller to provide electric power.

A method of operating a wind turbine system includes: determining, by an industrial process controller, if an actual wind speed value, received from an anemometer, of a wind at a location of the wind turbine system is less than a predetermined minimum wind speed value. If so, then calculating a command speed value that will cause a variable-speed drive to drive the motor/generator and a sail assembly at a speed that the sail assembly would turn if the actual wind speed value was the minimum wind speed value, such that the sail assembly turns and provides a visual effect. If not, then calculating a command speed value based on the actual wind speed value such that the variable-speed drive and the motor/generator will operate in a braking mode to recover a braking energy of a load of the wind on the sail assembly.
