Abstract

The aim of this invention is to produce a design for a wind power installation which provides a sufficiently high speed for the electricity generators, without power- consuming and expensive transmission arrangements, to use low wind speeds, and moreover a rational construction method which allows service and repair and allows a low construction cost. To achieve this aim, the following design principles are applied, which characterize the invention: instead of propellers, use is made of elongate rotors of relatively small diameter, which results in a considerably higher speed than for a propeller with the same torque, which has been established by trials using models. In order to increase the effective wind speed, the rotors are mounted in pairs with opposite directions of rotation in vertical frames provided with fixed guide rails which direct and increase the speed of the air flow. The opposite rotation of the rotors is used by driving both the rotor and stator of the generator, as a result of which the speed capacity is doubled. The rotors mounted in pairs in their frames constitute a module which is a complete operational wind power installation. <IMAGE>

Description

468 35 40 45 1 445 Beträffande rotorernas aerodynamiska utformning och verkningsgrad visar hitintills gjorda modellförsök goda utvecklingsmöjligheter. Problem- ställningen att överföra ett linjärt strömmande nxediums energi till en roterande rörelse med minsta möjliga turbulens och energiförlust före- faller att lättare kurma uppnås med den här beskrivna rotorkonstruktion- en än med nuvarande propellrar och turbinh jul. 468 35 40 45 1 445 Regarding the aerodynamic design and efficiency of the rotors shows hitherto made model experiments good development opportunities. Problem- the position to transfer the energy of a linearly flowing nxedium to a rotary motion with the least possible turbulence and energy loss easier curvature is achieved with the rotor construction described here. one than with current propellers and turbinh Christmas.

I princip kanödenna uppfinning även tillämpas för vissa typer av vatten- kraftsanläggrfingar.In principle, this invention can also be applied to certain types of water power plants.

Med avseende på xmderhåll och reparation är derma uppfinning helt över- lägsen alla hitintills kända system.With respect to maintenance and repair, this invention is completely below all hitherto known systems.

Så t.ex. har vindkraftverket enl. Fig.3 en på baksidan längsgående, in- byggd brygga varifrån alla elgeneratorer och övrig elektrisk utrustning är åtkomlig. Vid övriga reparationer finns två alternativ, antingen att byta ut skadade komponenter på platsen ( se rad 17-18) eller byta en hel modul med hjälp av lyftkranen på vindskännens tak.So e.g. has the wind power plant acc. Fig.3 a longitudinal, in- built bridge from which all electricity generators and other electrical equipment is accessible. For other repairs, there are two options, either that replace damaged components on site (see lines 17-18) or replace a whole module using the crane on the roof of the windshield.

Detta system innebär att en kontinuerligt fortlöpande modernisering är möjlig, praktiskt taget under drift, utan nämvärda driftsstörningar.This system means that a continuous continuous modernization is possible, practically during operation, without significant operational disturbances.
