Definitions
- the invention relates to a method for aligning the adjustable heliostats of a heliostat field, which reflects solar energy to a radiation receiver, using a computer that calculates or stores setpoint values for each heliostat of the heliostat field for at least one sun position.
- the direct solar radiation is concentrated on numerous large mirrors, which are tracked in two axes to the sun, to a radiation receiver, which is attached to the top of a solar tower.
- the highly concentrated radiation heats the up to several 100 m 2 large radiation receiver to high temperatures.
- the radiation receiver is an absorber, which is a heat transfer medium such as air, water, salt, thermal oil, is flowed through. This temperature values of 500 0 C to 1000 0 C are achieved.
- the heat generated is dissipated via the heat transfer medium from the absorber and supplied, for example, a steam turbine for generating electricity.
- the heliostats are movable mirrors whose mirror surface is usually 8 m 2 to 180 m 2 .
- 300 - 2000 heliostats or more are arranged in a heliostat field in such a way that the reflected solar radiation is exactly aligned with the absorber located in the tower.
- the heliostats can be moved by motor in two directions: Az ⁇ mutterrorism (horizontal pivoting) and an elevation movement (changing the elevation angle).
- each heliostat has a sensor for determining the current azimuth angle and another sensor for determining the current elevation angle.
- a central computer receives the data of all sensors.
- the calculator contains an astronomical sun position software and calculates the respective position of the sun based on date and time and adjusts the heliostats so that the incident solar radiation is reflected by each heliostat onto the radiation receiver. The respective position of the heliostat within the heliostat field is taken into account.
- the tracking of the individual heliostats takes place in such a way that the respective current setpoint position of the heliostats is recalculated in comparison with the sun position data and the data from the angle sensors and reported via a data network to the drives of the heliostats which approach the new position.
- the invention has for its object to provide a method for aligning the adjustable heliostat of a heliostat, in which the sensory complexity for determining the actual orientation of the individual heliostats is reduced.
- the inventive method is defined by the patent claim 1. It is characterized in that for determining the current setting values of the heliostats, a distance measuring device is set up at a measuring location, which measures the distance of several measuring points of the mirror surface of a heliostat from the measuring location, and in that a setting device on the heliostat is controlled by the computer in such a way that predetermined Target setting values are achieved.
- a central measurement of the alignment of numerous heliostats takes place without corresponding measuring devices or sensors being present at the heliostats.
- the measurement is carried out without contact by means of a highly sensitive distance measuring device, which is directed to the mirror surface of the heliostat and carries out distance measurements at several measuring points there.
- the plane of the respective mirror surface can be determined. This results in the azimuth angle and the elevation angle of the mirror surface. These are calculated by the calculator.
- the computer can now bring the heliostat in the desired orientation by controlling the actuator.
- the achievement of the desired alignment is recognized by the fact that the target setting values are reached.
- the measuring location can be arranged at the radiation receiver or near the radiation receiver. However, the invention is not limited to such a positioning of the measuring location. Rather, the measuring location can be arranged at any point from which visual contact with all heliostats of the relevant heliostat field exists.
- the measuring points on the mirror surface of a heliostat can be measuring points which can be distinguished from the remaining parts of the mirror surface, the distance measuring device determining the distance between each measuring point and the measuring location.
- the distance measuring device determines the distance between each measuring point and the measuring location.
- a measuring beam emitted by the removal measuring device is guided in a scanning process over the mirror surface of a heliostat. It can be determined continuously or pointwise the change in distance. Based on the changes in distance, the course of the mirror surface can also be determined. In this way, an additional investigation on Spiegelfehier is possible.
- the invention further relates to a heliostat with heliostats, which reflect the solar radiation to a radiation receiving device, wherein the heliostat has an adjusting device for aligning the heliostat according to the position of the sun.
- a non-contact distance measuring device is provided, which can be directed to individual heliostats and determines the plane of the mirror surface on the basis of measuring points of the mirror surface of the heliostat.
- a computer controls the adjusting device of the relevant heliostat such that the radiation reflected by the mirror surface strikes the radiation receiver at a given position in the sun.
- This device has the advantage that no sensors for determining the respective heliostat position are needed. ⁇ 3 ⁇
- the distance measuring device preferably consists of a radar device with a frequency above 10 GHz, in particular above 50 GHz.
- the radiation receiving device is located on a tower or raised above the heliostat field.
- heliostat field can also be a subfield.
- the orientations of the heliostats are measured from a central measuring location.
- local position sensors on the heliostats - two angle sensors per heliostat - are dispensable. It is also possible to dispense with the necessary hardware for the data transfer to the central controller.
- the cost of maintenance is reduced because only one measuring system is to be checked.
- Fig. 1 is a schematic plan view of a solar tower power plant
- Fig. 2 is a schematic representation of a heliostat with the corresponding adjusting device.
- the solar power plant shown in the drawings has a heliostat field 10 which is arranged around a tower.
- the heliostat field contains numerous heliostats 12. These are mirrors which reflect the impinging solar radiation with their front mirror surface 13.
- the heliostats are arranged in arbitrary form around the tower 11 around.
- Mounted on the tower is a radiation receiver (not shown) to which the individual heliostats are aligned so that the solar radiation is concentrated on the radiation receiver. The radiation is absorbed and the radiant energy is converted into heat. About a heat transfer medium, this heat is dissipated from the radiation receiver to a consumer.
- each heliostat is provided with an actuator.
- This consists of an azimuth drive 15 and an elevation drive 16.
- These drives are high-precision motors, such as stepper motors.
- the azimuth drive 15 causes a pivoting of the mirror surface 13 in the horizontal direction.
- the elevation drive 16 causes a Verschwenkungsver selectedung the elevation angle.
- a distance measuring device 20 is installed, which is a radar device in the gigahertz range.
- the radar device is shown here schematically as transmitter 21 and receiver 22. It can be targeted to each of the heliostats and within the heliostat also to different sites.
- rotary motors 23 are provided with which a highly accurate target setting is possible.
- the distance measuring device 20 including the rotary motors 23 is controlled by a central computer 25.
- the computer 25 contains the position and position data of all heliostats 12. In addition, it contains a high-precision astronomical sunshine software, so that at any time accurate information about the position of the sun at the respective location.
- each measuring point can be a measuring point whose reflection properties differ from those of the mirror surface 13, so that it can be recognized by the distance measuring device as the target point.
- the measuring points can lie not only on the mirror, but also laterally, above and below the mirror.
- the location where the distance measuring device 20 is located is referred to as a measuring location MO.
- the distance measuring device measures the distance of each measuring point from the measuring location MO in a highly accurate manner.
- the plane in which the mirror surface 13 is located can be determined.
- the computer 25 determines the desired orientation of the heliostat and controls the adjusting device 15, 16 in such a way that the actual orientation coincides with the desired orientation. In this way, a central control of the orientation of each heliostat is done.
- the three-point measurement described suffices.
- the invention is also suitable for detection intentional or unwanted unevenness of the mirror surface.
- a scanning beam can be guided over the mirror surface, wherein at the same time the varying distance to the measuring location MO is determined. In this way, a desired mirror curvature can be checked or it can be determined whether a mirror surface, which should be flat, is uneven.
