Definitions

  • This invention relates to a wind power plant comprising at least one wind power station, which comprises a wind turbine, an electric generator driven by this wind turbine and a rectifier, and an electric direct voltage connection between the rectifier arranged at the wind power station and an inverter, the alternating voltage side of which is connected to a transmission or distribution network, the inverter being arranged on the network side of the plant.
  • the invention is preferably intended to be used in such cases where the connection between the generator and the transmission or distribution network includes a cable intended to be submerged into water. Consequently, expressed in other words, it primarily relates to such applications where one or several wind turbines with associated generators are intended to be placed in seas or lakes, wherein the cable connection extends to the transmission or distribution network placed on land.
  • the invention can, however, also imply advantages in cases where the wind turbines and the generators are located on land and the connection, which in that case not nec- essarily has to consist of a cable but instead can be realized in the form of aerial lines or cables, connects several such wind turbines/generators with the transmission or distribution network.
  • the voltage variation may not be more than 4%. Different countries have different regulations and as a rule the regulations are mitigated in case of a lower voltage level on the transmission line. Voltage variations could also have to be treated differently depending on time intervals. Rapid voltage variations causes "flicker", i.e. light variations in glow lamps, which is regulated in rules.
  • a solution to the problem above with long cable distances is to transmit the power with high-voltage direct voltage.
  • the cable can then be drawn right up to a strong network.
  • Another advan- tage is that DC-transmissions have lower losses than AC-trans- missions. From a technical point of view the cable distance can then be of unlimited length.
  • a HVDC-link consists of a rectifier station, a transmission line (cable or aerial line), an inverter station and filters for removing overtones generated during the conversion.
  • thyristors are used for rectification and inversion.
  • Thyristors can be switched on but not switched off; the commutation takes place at the zero- crossing of the voltage, which is determined by the alternating voltage, and the converters are therefore called line commu- fating.
  • a disadvantage with this technique is that the converters consume reactive power and cause current overtones, which are sent out in the network.
  • IGBT Insulated Gate Bipolar Transistor
  • An IGBT Insulated Gate Bipolar Transistor
  • the converters can be produced ac- cording to a completely different principle, so called self-com- mutating converters.
  • a self-commutating converter is characterized in that the voltage is built up by a rapid pulse pattern , which is generated by the converter.
  • the voltage differ- ence between the pulse pattern and the sinusoidal network voltage will lie above the inductances on the network side.
  • inverters There are two types of self-commutating inverters; a voltage stiff, VSI (Voltage Source Inverter) and a current stiff, CSI (Current Source I nverter), with somewhat different characteristics.
  • VSI Voltage Source Inverter
  • CSI Current Source I nverter
  • a synchronous generator is not to any disadvantage, but rather to an advantage, since the asynchronous generator requires a more expensive and more complicated rectifier. If it is desired to have a direct driven generator and consequently eliminate the need of a gear unit between the turbine and the generator, the generator must be synchronous since it will be provided with so many poles. In other words, a direct driven generator requires a DC-intermediate link. In the concept it is also possible to actively regulate the moment by changing the trigger angle, if a controlled rectifier is used. In most concepts having a variable rotational speed, an external active rotational speed control is furthermore provided by so called pitch control, which implies that the blade angle is changed on the turbine. A disadvantage with a variable rotational speed according to the related concepts is the price of the required power electronics and furthermore that the maintenance of such power electronics out at sea will be difficult and costly.
  • the purpose of the invention is to achieve, with a more simple and cheap system for variable rotational speed, the same good power transmission from a sea-based wind park to the land- based network as offered by a modern HVDC-system, with the possibility to eliminate the necessity of transformers and controlled power electronics in the wind power stations. This is very valuable since all maintenance carried out at sea is costly and difficult to perform.
  • a further purpose of the invention is to be able to have such a high voltage on the DC-transmission that low losses are obtained also for a large wind park, for instance on 50-1 00 MW.
  • the purpose of the invention is achieved primarily through the features defined in the characterizing part of the subsequent claim 1 .
  • the unsolved problem of prior technique that the DC- voltage will be too low is consequently solved by connecting the DC/DC-converter out at sea with its low-voltage side electrically connected to the rectifier and its high-voltage side electrically connected to the inverter.
  • Such a DC/DC-converter functions in about the same way as a transformer for DC; it steps up the direct voltage a factor n: 1 and steps down the direct current as 1 :n, where n is the conversion. This implies that the inverter and the rectifier are no longer connected in series.
  • the rectifier is formed as a passive diode rectifier in series with a local step-up direct voltage converter.
  • the local step-up direct voltage converter suitably consists of a choke, a series connected IGBT-valve and a series connected diode. This can also be the basic design of a DC/DC- converter.
  • the inverter is constituted by a voltage stiff, self-commutated system, the characteristics of which are superior to a line commutated system from a power regulating point of view.
  • a voltage stiff, self-commutated system the characteristics of which are superior to a line commutated system from a power regulating point of view.
  • Such a system is characterized, in an embodiment of the invention, in that at least one capacitor is connected in parallel over the inverter on the DC-link and that inductances are connected in series with each phase on the network side.
  • the valves are constituted by series connected IGBT.s.
  • thermore the conventional insulation technology for stator windings is sensitive to temperature variations, humidity and salt, which a wind turbine generator is exposed to.
  • a solid insulation is used for at least one winding in the generator, which insulation preferably is performed according to the subsequent claim 14.
  • the winding has more specifically the character of a high-voltage cable.
  • a generator manufactured in this way creates the prerequisites of achieving considerably higher voltages than conventional generators. Up to 400 kV can be achieved.
  • such an insulation system in the winding implies insensibility to salt, humidity and temperature variations.
  • the high output voltage implies that transformers can be completely excluded, which implies avoidance of the already mentioned disadvantages such as increase in costs, reduction in effectivity, risks of fire and risks for the environment. The latter are due to the fact that conventional transformers contains oil.
  • a generator having such a winding formed by a cable can be produced by threading the cable in slots performed for this purpose in the stator, whereupon the flexibility of the winding cable implies that the threading work can be easily performed.
  • the two semiconducting layers of the insulation system have a potential compensating function and consequently reduce the risk of surface glow.
  • the inner semiconducting layer is to be in electrically conducting contact with the electrical conductor, or a part thereof, located inwardly of the layer, in order to obtain the same potential as this.
  • the inner layer is intimately fastened to the solid insulation located outwardly thereof and this also applies to the fastening of the outer semiconducting layer to the solid insulation.
  • the outer semiconducting layer tends to contain the electrical field within the solid insulation. In order to guarantee a maintained adherence between the semiconducting layers and the solid insulation also during temperature variations, the semiconducting layers and the solid insulation have essentially the same thermal coefficient of expan- sion.
  • the outer semiconducting layer in the insulation system is connected to ground potential or otherwise a relatively low potential.
  • the generator has a number of features which have already been mentioned above and which distinctly differ from conventional technology. Further features are defined in the dependent claims and are discussed in the following :
  • the winding in the magnetic circuit is produced of a cable having one or several permanently insulated electrical conductors with a semiconducting layer at the conductor and outwardly of the solid insulation.
  • Typical cables of this kind are cables having an insulation of cross-linked polyethylene or ethylene-propene, which for the purpose here in question are further developed concerning stands of the electrical conductor and also the character of the insulation system.
  • Cables having a circular cross section are preferred, but cables having another cross section can also be used, for instance in order to achieve a better packing density.
  • Such a cable makes it possible to design a laminated core of the magnetic circuit in a new and optimal way as concerns slots and teeth.
  • the winding is produced with a stepwise increasing insulation or the best utilization of the laminated core.
  • the winding is produced as a concentric ca- ble winding, which makes it possible to reduce the number of coil end crossings.
  • the shape of the slots is adapted to the cross section of the winding cable so that the slots are in the form of a number of cylindrical openings extending axially and/or radially outwardly of each other and having constrictions running between the layers of the stator winding.
  • the shape of the slots is adapted to the cable cross section in question and to the stepwise changing thickness of the insulation of the winding.
  • the stepwise insulation makes it possible for the magnetic core to have an essentially constant tooth width independent of the radial extension .
  • winding conductor consisting of a number of layers brought together, i.e. insulated strands, does not necessarily have to be correctly transposed, and non-insulated and/or insulated from each other.
  • the cable can have an outer diameter in the order of 10- 40 mm and a conductor area in the order of 1 0-200 mm 2 .
