Abstract

Vorrichtung zur zusätzlichen Stromgewinnung in Mastkonstruktionen zur Hochspannungs-Gleichstrom-Übertragung, dadurch gekennzeichnet, dass Vertikalrotoren zur Windstromerzeugung in der Mastmitte integriert sind.Device for additional power generation in mast structures for high-voltage direct current transmission, characterized in that vertical rotors for wind power generation are integrated in the middle of the mast.

Description

Anordnung zur Windstromerzeugung in HGÜ-Mastkonstruktionen.Arrangement for wind power generation in HVDC mast constructions.

Der zwangsweise große Abstand zwischen den Stromkabeln oberirdisch geführter Hochspannungs-Gleichstrom-Übertragungsanlagen führt zu Mastkonstruktionen, die ein größeres Freifeld zwischen den beiden Hochspannungskabeln belassen.The forcibly large distance between the power cables of above-ground high-voltage direct current transmission systems leads to mast constructions, which leave a larger open field between the two high-voltage cables.

So haben sich Masten zur HGÜ-Übertragung in einer Ausführung bewährt, die bei etwa 40 m Höhe eine Ausladung gleicher Größe und mittig dem entsprechend einen erheblichen Freiraum aufweisen.Thus, masts have been proven for HVDC transmission in a design that have at about 40 m height a projection of the same size and in the middle of the corresponding a considerable amount of space.

Aufgabe vorliegender Erfindung ist es, diese aufwendige Konstruktionen weiter zu nutzen.Object of the present invention is to continue to use these expensive constructions.

Erfindungsgemäß erfolgt dies durch den Einsatz von Vertikalrotoren zu weiterer Stromerzeugung und Spannungs-Stabilisierung.According to the invention this is done by the use of vertical rotors for further power generation and voltage stabilization.

Im Freifeld der Masten zwischen den HGÜ-Leitunge werden dazu Vertikal-Windrotoren eingesetzt, die nicht der Windrichtung nachgeführt werden müssen und zwar vorzugsweise jener von Savonius-Typ, die zwar ungünstigeren Wirkungsgrad aufweisen, aber selbst-anlaufend sind und kaum Vibrationsprobleme verursachen – und daher keine zusätzlichen Aufwendungen an der Mastkonstruktion verlangen.In the open field of the masts between the HVDC lines to vertical wind rotors are used, which need not be tracked the wind direction, preferably those of Savonius type, although less favorable efficiency, but self-starting and hardly cause vibration problems - and therefore do not require additional expenses for the mast construction.

Sie haben werter den Vorteil, auch bei der vergleichsweise geringen Anbringungshöhe von mittig etwa 30 m über dem Boden noch akzeptable Stromerträge zu erbringen und auch bei ungünstigen Windbedingungen in Erdnähe, wie Wirbelbildung und Scherwinden noch effektiv zu sein – denn die Position der Strommasten wird – im Gegensatz zu Windkraftanlagen – natur – gemäß kaum vom möglichen Windertrag abhängig gemacht.They have the advantage, even at the relatively low mounting height of about 30 m above the ground still provide acceptable power yields and even in adverse wind conditions near the earth, such as vortex formation and shear winds to be effective - because the position of the power poles is - in Contrary to wind turbines - nature - hardly made dependent on the possible wind yield.

Es ist nun möglich, den Stromertrag konventionell über zusätzliche Kabel – etwa durch Mitverwendung der Top-Abspannkabel – zu Umspannstationen weiter zu leiten. Denkbar ist aber auch, mit Anwendung von Multipol-Drehstromgeneratoren und Schaltnetzteilen die Spannung auf die HGÜ-typischen 180 kV bis 360 kV zur transformieren und direkt einzuspeisen, um Übertragungsverluste zu kompensieren und die Spannung ggf. zu stabilisieren.It is now possible to forward the power output conventionally via additional cables - for example by using the top guy cables - to substations. It is also conceivable, however, with the application of multipole three-phase generators and switching power supplies to transform the voltage to the HVDC-typical 180 kV to 360 kV and feed directly to compensate for transmission losses and possibly stabilize the voltage.

In einer erweiterten Ausführung ist sogar denkbar, Strom-Überkapazitäten, die die HGÜ-Leitung überlasten würden, bedarfsweise in eine motorische Bewegung der Rotoren an den Strommasten zu wandeln und so abzubauen.In an expanded version, it is even conceivable to convert excess current capacities that would overload the HVDC line, if necessary, into a motorized movement of the rotors on the power poles and thus to reduce them.

Eine weitere, an sich nahe liegende Anwendung wäre, die Rotationsenergie der Windkraft-Elemente in Van de Graaff Generatoren umzusetzen, diese durch Steuerung des Kamm-Abstandes von Band in ihrer Spannung zu steuern und durch Abgriff vom Hohlkugel-Zwischenspeicher direkt in die HGÜ-Leitung einzuspeisen. Die Machbarkeit dieser Kombination erscheint derzeit allerdings noch fraglich, wogegen die Wirkungsgrade der Van de Graff Generatoren in jüngerer Zeit durch Ihre Anwendung in Teilchenbeschleunigern wesentlich verbessert sein sollen.Another obvious application would be to convert the rotational energy of the wind power elements into Van de Graaff generators, to control them by controlling the comb spacing of the band in their voltage, and by tapping the hollow ball buffer directly into the HVDC line feed. However, the feasibility of this combination is currently still questionable, whereas the efficiencies of the Van de Graff generators have recently been significantly improved by their use in particle accelerators.

Zwar sind Windkraft-Generatoren in oder an Strommasten nach DE 4106976 A1 , DE 195 32 880 C1 und CN 201206531 (Y) bekannt. Bei den derzeitig verwendeten Masten für Mehrphasen-Wechselstrom geringerer Spannung waren die Masten jedoch nicht hoch genug, um für Windenergiegewinnung effizient zu sein und insbesondere nicht so angelegt, dass sich Rotoren ausreichend großen Durchmessers direkt in sie integrieren liessen.Although wind generators are in or on power poles after DE 4106976 A1 . DE 195 32 880 C1 and CN 201206531 (Y) known. However, in the current multiphase alternating current masts of lower voltage, the masts were not high enough to be efficient for wind energy production and, in particular, were not designed so that rotors of sufficiently large diameter could be directly integrated into them.

Anordnungen seitlich oder über der regulären Masthöhe, wie bei DE 196 36 240 A1 sind jedoch ungleich aufwändiger, so dass sie sich nur an Standorten mit hohem Windaufkommen lohnen könnten. Dies widerspricht jedoch der Standortlogik für Stromleitungen.Arrangements laterally or above the regular mast height, as in DE 196 36 240 A1 However, they are much more complex, so that they could only be worthwhile in locations with high wind loads. However, this contradicts the location logic for power lines.

Der erfinderische Schritt ergibt sich daher aus der Erkenntnis und Nutzung der neuen Gegebenheiten des Mastbaus.The inventive step therefore results from the knowledge and use of the new conditions of the tower construction.

Die Erfindung ist nachfolgend in der Zeichnung 1 näher erläutert:The invention is below in the drawing 1 explained in more detail:

1 zeigt einen der derzeit typischen HGÜ-Gittermasten 1 mit den beiden Freileitungen 15 und 16 an den Aufhängungen 2 und 3, die an den jeweiligen Isolatoren 4 und 5 befestigt sind. 1 shows one of the currently typical HVDC lattice masts 1 with the two overhead lines 15 and 16 on the suspensions 2 and 3 attached to the respective insulators 4 and 5 are attached.

Der zunächst vorgesehene Savonius-Rotor 7 ist im Freiraum in der Mitte der Mastkonstruktion zwischen dem Mittelpunkt der oberen Traverse 8 und der Basis-Zusammenführung 9 aufgehängt, unter der ein möglicher zweiter Rotor 11 angeordnet sein kann, der auf den gleichen Generator 10 arbeitet, der unter dem Rotor 7 zwischen beiden Rotoren angeordnet ist, wie es sich aus Platz- und Baugründen anbietet.The initially provided Savonius rotor 7 is in the open space in the middle of the mast construction between the center of the upper crossbar 8th and the base merge 9 suspended, under which a possible second rotor 11 can be arranged on the same generator 10 working under the rotor 7 is arranged between the two rotors, as it offers space and grounds.

Die Top-Kabel 13 und 14, die regulär zur Abspannung und für den Blitzschutz verwendet werden, könnten hier – isoliert und unter Anwendung von Blitzschutz-Funkenstrecken – auch zum Transort des zusätzlich generierten Stromes zum nächsten Umspannwerk Verwendung finden.The top cables 13 and 14 , which are used regularly for bracing and for lightning protection, could also be used here - isolated and using lightning protection spark gaps - to trans- port the additionally generated electricity to the nearest substation.
