Abstract
Eine Windenergieanlage, aufweisend einen mit einem Windrotor (110) verbundenen und durch den Windrotor (110) angetriebenen Generator (120), eine Gleichrichter-Einheit (130) geeignet zur Erzeugung von Gleichstrom aus dem Ausgangsstrom des Generators (120); und eine Wechselrichter-Einheit (140) zur Erzeugung von Wechselstrom aus dem von der Gleichrichter-Einheit (130) erzeugten Gleichstrom, wobei der von der Wechselrichter-Einheit (140) erzeugte Wechselstrom eine Frequenz von 16,7 Hz aufweist.A wind turbine comprising a generator (120) connected to a wind rotor (110) and driven by the wind rotor (110), a rectifier unit (130) adapted to generate direct current from the output current of the generator (120); and an inverter unit (140) for generating AC power from the DC power generated by the rectifier unit (130), the AC power generated by the inverter unit (140) having a frequency of 16.7 Hz.
Description
Ausführungsformen der Erfindung beziehen sich auf eine Energieversorgungsanlage für Sonderstromversorgungsnetze sowie auf Windenergieanlagen für solche Sonderstromversorgungsnetze.Embodiments of the invention relate to a power supply system for special power supply networks and to wind turbines for such special power supply networks.
Während das öffentliche Stromversorgungsnetz auf der Übertragung von 3-phasigen Wechselstrom mit einer Frequenz von 50 Hz beruht, werden Sonderstromversorgungsnetze, z. B. die Bahnstromnetze in einigen europäischen Ländern mit Gleichstrom oder mit 1-phasigen Wechselstrom mit einer Frequenz von 16,7 Hz betrieben. Dabei speist ein vom öffentlichen Stromversorgungsnetz unabhängiges Sonderstromversorgungsnetz, beispielsweise ein 110 kV/16,7 Hz, 15 kV Oberleitungsanlagen. In das unabhängige Sonderstromversorgungsnetz speisen Wärmekraftwerke und Wasserkraftwerke direkt Strom ein. Zusätzlich kann das Sonderstromversorgungsnetz an Netzkopplungen mit Umrichtern oder Umformern Strom aus dem öffentlichen Stromversorgungsnetz beziehen. Im Zuge der Reduzierung der Kosten für CO2-Lizenzen errichten und unterhalten die Betreiber von Sonderstromversorgungsnetzen auch seit mehreren Jahren Windparks, wobei der in den Windparks erzeugte Strom zunächst in das öffentliche Stromversorgungsnetz und vom öffentlichen Stromversorgungsnetz über 50 Hz:16,7 Hz-Umrichter in das Sonderstromversorgungsnetz eingespeist wird.While the public power grid based on the transmission of 3-phase AC with a frequency of 50 Hz, special power grids, z. As the traction power grids operated in some European countries with direct current or with single-phase alternating current with a frequency of 16.7 Hz. This feeds a separate from the public power grid special power supply network, such as a 110 kV / 16.7 Hz, 15 kV overhead line systems. Thermal power plants and hydroelectric power plants feed electricity directly into the independent special power grid. In addition, the special power supply network can receive power from the public power grid at network couplings with converters or converters. In the course of reducing the costs of CO 2 licenses, the operators of special power supply networks have been constructing and maintaining wind farms for several years, with the electricity generated in the wind farms first in the public power grid and over 50 Hz in the public power grid: 16.7 Hz is fed into the special power supply network.
Es besteht die Aufgabe, das Einspeisen von Windenergie in Sonderstromversorgungsnetze wirtschaftlicher zu gestalten.The object is to make the feeding of wind energy in special power supply networks more economical.
Die Aufgabe wird mit dem Gegenstand der unabhängigen Schutzansprüche gelöst. Vorteilhafte Ausführungsformen sind in den Unteransprüchen genannt. Eine Ausführungsform der Erfindung betrifft eine Windenergieanlage. Ein von einem Windrotor angetriebener Generator erzeugt einen Wechselstrom der von einer Gleichrichter-Einheit gleichgerichtet und geglättet wird. Eine Wechselrichter-Einheit erzeugt aus dem von der Gleichrichter-Einheit erzeugten Gleichstrom direkt 1-phasigen Wechselstrom mit einer Frequenz von 16,7 Hz, was der Frequenz im Bahnstromnetz in einigen Regionen Europas entspricht.The object is achieved with the subject matter of the independent claims. Advantageous embodiments are mentioned in the subclaims. An embodiment of the invention relates to a wind energy plant. A generator driven by a wind rotor generates an alternating current which is rectified and smoothed by a rectifier unit. An inverter unit generates directly from the direct current generated by the rectifier unit 1-phase alternating current with a frequency of 16.7 Hz, which corresponds to the frequency in the traction current network in some regions of Europe.
Die direkte Umrichtung auf die Frequenz des Bahnstromnetzes vermeidet elektrische Verluste bei der Umsetzung von 50 Hz auf 16,7 Hz Wechselspannung. Die Anpassung bestehender Windenergieanlagen zur Verwendung in einem Bahnstromsystem beziehungsweise zur direkten Einspeisung in das Bahnstromnetz lässt sich mit vergleichsweise geringem Aufwand durchführen.The direct conversion to the frequency of the traction current network avoids electrical losses in the conversion of 50 Hz to 16.7 Hz AC voltage. The adaptation of existing wind turbines for use in a traction current system or for direct feed into the traction current network can be carried out with relatively little effort.

Das Getriebe
Die Ausführungsform der Windenergieanlage
Konventionelle Windenergieanlagen sind für den Anschluss an öffentliche Stromversorgungsnetze ausgelegt und liefern daher am Ausgang eine 3-phasige 50 Hz Wechselspannung, die über einen Transformator auf die Spannung im örtlichen Stromversorgungsnetz hoch transformiert wird. Zum Anschluss an ein Bahnstromnetz wird bisher der durch solche Windenergieanlagen erzeugte Strom an Netzkopplern durch Umrichter oder Umformer von 50 Hz auf 16,7 Hz umgesetzt. Eine solche zusätzliche Umsetzung oder Umformung entfällt mit den Windenergieanlagen nach
