Problems solved by technology
The construction of the existing heliostat field involves civil engineering, installation, and commissioning. Due to the large number of heliostats, the construction period of the heliostat field is very long. Usually, after the power generation island, light tower, molten salt and heat storage system are completed, the fixed The construction of the heliostat field has not yet been completed. The construction of the heliostat field has lengthened the construction period of the entire solar thermal power station. The construction time of the entire solar thermal power station is generally more than twice that of a thermal power plant of the same scale, which increases the construction cost.

The invention belongs to the technical field of condensation type photo-thermal power stations, and particularly relates to a construction method of a photo-thermal power station. The method comprises heliostat field construction and is characterized in that three or more working sectors are arranged on a heliostat field in the circumferential direction with a light tower as the center, and each working sector is provided with three or more construction areas from inside to outside; mirror field civil engineering, mirror body installation, single debugging, remote transmission, optical calibration and integral control experiments are circularly carried out in construction areas one by one along all the sectors around the light tower; furthermore, the number of the working sectors is 4 to 8; moreover, each working sector is provided with three to eight construction areas from inside to outside; and what's more, when 60% or more than 60% of heliostats in the heliostat field are available, the photo-thermal power stations start to generate power. The total construction period of the photo-thermal power stations can be shortened, income can be obtained when the power stations are constructed, and the construction cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of concentrating photothermal power plants, and in particular relates to a construction method of a photothermal power station. Background technique [0002] At present, the conventional construction process of solar thermal power plants requires that after the power generation island, light tower, molten salt and heat storage system are installed, the entire heliostat field is put into use, and the molten salt is heated to the rated parameters before starting to use heat. The salt produces high-temperature, high-pressure steam, which drives the steam turbine to generate electricity. The construction of the existing heliostat field involves civil engineering, installation, and commissioning. Due to the large number of heliostats, the construction period of the heliostat field is very long. Usually, after the power generation island, light tower, molten salt and heat storage system are completed, the fixed T...
