Henrik Stiesdal (born April 14, 1957) is a Danish inventor and businessman in the modern wind power industry. In 1978, he designed one of the first wind turbines representing the so-called "Danish Concept" which dominated the global wind industry through the 1980s. [1] Until 2014, Stiesdal was the chief technology officer of Siemens Wind Power ...
In 2010, Siemens Wind Power acquired 49% of A2SEA (an offshore wind farm installation company) from DONG Energy (now Ørsted A/S). [39] [40] In 2017, A2SEA was sold to GeoSea. [41] A factory established in Linggang (Siemens Wind Power Blades (Shanghai) Co., Ltd.) near the Yangshan Deep Water Port began production in 2010. [42]
Direct-drive mechanisms are used in applications ranging from low speed operation (such as phonographs, telescope mounts, video game racing wheels and gearless wind turbines) [14] [15] [16] to high speeds (such as fans, computer hard drives, VCR heads, sewing machines, CNC machines and washing machines.)
An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbine components : 1-Foundation, 2-Connection to the electric grid, 3-Tower, 4-Access ladder, 5-Wind orientation control (Yaw control), 6-Nacelle, 7-Generator, 8-Anemometer, 9-Electric or Mechanical Brake, 10-Gearbox, 11-Rotor blade, 12-Blade pitch control, 13-Rotor hub
A variable speed may or may not have a gearbox, depending on the manufacturer's desires. Wind turbines without gearboxes are called direct-drive wind turbines. An advantage of a gearbox is that generators are typically designed to have the rotor rotating at a high speed within the stator. Direct drive wind turbines do not exhibit this feature.
SIMATIC is a series of programmable logic controller and automation systems, developed by Siemens. Introduced in 1958, the series has gone through four major generations, the latest being the SIMATIC S7 generation. The series is intended for industrial automation and production. The name SIMATIC is a registered
DTC was applied to doubly fed machine control in the early 2000s. [18] Doubly fed generators are commonly used in 1-3 MW wind turbine applications. Given DTC's outstanding torque control performance, it was surprising that ABB's first servo drive family, the ACSM1, was only introduced in 2007. [19]
Adwen GmbH (now Siemens Gamesa Renewable Energy Deutschland GmbH) is an offshore wind service company headquartered in Bremerhaven, Germany. It is a wholly owned subsidiary of Spanish-German company Siemens Gamesa. Previously the company designed, assembled, and installed 5-Megawatt wind turbines for offshore wind farms.
