Definitions

  • This invention relates to a solar field and a method for assembling the solar field.
  • One type of solar power plant comprises a solar field which utilizes a “radiation concentrator collector” which concentrates the solar radiation by focusing it onto a smaller area, e.g., using mirrored surfaces or lenses.
  • a reflector which is typically parabolic, receives and reflects (focuses) incoming solar radiation onto a radiation absorber, which is formed as a tube.
  • the tube radiation absorber is concentrically surrounded by a treated glass enclosure tube to limit the loss of heat.
  • the collector system further includes means to track the sun.
  • the tube radiation absorber is made of metal with a coating having a high solar radiation absorption coefficient to maximize the energy transfer imparted by the solar radiation reflecting off the reflector.
  • a heat transfer medium e.g. heat transfer fluid (HTF), which is typically a liquid such as oil, flows within the tube radiation absorber.
  • HTF heat transfer fluid
  • the thermal energy is transported by the HTF to provide energy to, e.g., a thermal-electric power plant to drive one or more power-generation systems thereof, in order to generate electricity in a conventional way, e.g., by coupling the axle of each of the turbines to an electric generator.
  • a thermal-electric power plant is a steam-electric power plant, which uses thermal energy provided thereto to produce steam to drive turbines thereof, which in turn drive a generator, thus generating electricity.
  • the HTF flows within a tube, which is partially constituted by the tube radiation absorber.
  • the entire length of the tube should be designed so as to limit thermal losses therefrom.
  • it is surrounded by a tube or pipe of a larger diameter, with the space therebetween being evacuated in order to limit heat loss due to convection.
  • a method for automatically assembling a solar field comprising following steps: a) Providing at least one solar collector unit with a radiation concentrator collector comprising a radiation absorber with an absorber tube for a flow-through of a heat transfer medium and a parabolic mirror for focusing solar radiation onto the absorber tube of the radiation absorber for heating up the heat transfer medium flowing through the absorber tube; b) Transporting the solar unit to a target location of the solar field; and c) Assembling the solar unit on the target location of the solar field.
  • a solar collector unit having a tube support for supporting the absorber tube and/or having a reflector support for supporting the parabolic mirror and/or having a mirror tracker for tracking the parabolic mirror based on the beaming direction of the radiation of the sunlight.
  • a plurality of solar collector units are provided and assembled together at the target location of the solar field. Especially all of the solar units of a solar field are manufactured and tested before the solar field is built up with them.
  • transport vehicle for the transporting the solar collector unit
  • the vehicles are designed such that the solar units can be supported in a save way.
  • a solar field with a plurality of prefabricated solar collector units is provided.
  • the solar collector unit are assembled together, wherein each of the solar units comprises a radiation concentrator collector comprising a radiation absorber with an absorber tube for a flow-through of a heat transfer medium and a parabolic mirror for focusing solar radiation onto the absorber tube of the radiation absorber for heating up the heat transfer medium flowing through the absorber tube.
  • FIG. 1 is a perspective view of a typical solar concentrator as part of a solar thermal power plant
  • FIG. 2 is a cross-sectional view of the heat collecting element (HCE) taken along line II II in FIG. 1 ;
  • the HCE 106 comprises a tube radiation absorber (TRA) 110 through which a thermal fluid flows, surrounded by a glass tube 112 along its length.
  • TRA tube radiation absorber
  • This tube is called UVAC (Universal Vacuum Air Collector).
  • a thermal fluid which is used to heat a working fluid in a separate loop to drive a power-generation cycle, flows within the TRA.
  • the thermal fluid is heated by the concentrated solar radiation.
  • the space between the TRA 110 and the glass tube 112 is evacuated in order to minimize heat loss due to cooling of the thermal fluid within the TRA by convection.
  • Each end of the glass tube 112 may be enclosed by flexible external shield member (not illustrated).
  • HCE support posts (absorber supports) 108 are provided, e.g., at regular intervals along the length of the HCE, to maintain the position of the HCE 106 at or near the focus of the parabola of the reflecting surface 102 . They are designed to pivot about a bottom end thereof, in the direction along which the HCE extends.
  • the solar collector unit (solar field basic component) is approximately 12 meters long and 5.7 meters wide and consists of a main torque tube, a reflector support, and reflectors. For example eight solar collector units are assembled together to form a solar collector assembly (SCA).
  • SCA solar collector assembly
  • Metal base columns are based on a concrete foundation and holding the parabolic mirrors.
  • a drive pylon is where the hydraulic system is located in order to rotate the solar complete collector assembly according to the sun's movement. All electrical & communications panels are mounted on these pylons.
  • the solar field as a part of a complete power plant can be assembled automatically.
  • the parabolic mirrors (parabolas) and the triple UVACs will be assembled at the site, i.e., at the Portable Assembly Building (PAB), and will be dispatched to the Solar Field, to be installed according to a construction plan.
  • the construction plan defines a dispatch of the other components of the solar field as well (pylons, crossover-pipes, ball joints, risers) so as to coordinate the timing of their arrival to their location in the solar field and their installation.
  • the parabolas delivered at the outlet of the PAB will be transported to the solar field on a specially designed parabola carrying cart (transport vehicle).
  • the SCA is includes metal parts manufactured in standard process of steel structure.
  • the driving system is installed in an assembly line.
  • the final station includes a set of tests to inspect and run a solar collector unit, to ensure the required performance of the solar collector unit.
  • the line includes special equipment that has been developed for mounting the parabola components.
  • a measurement station inspects the final parabola accuracy.
  • a special gripper developed to transfer the parabola from the line to the wagon and later to lift it onto the SCA.
