Group-control solar high-temperature thermal power generation thermal-arrest control system

Abstract

The invention provides a group-control solar high-temperature thermal power generation thermal-arrest control system, and belongs to the technical field of solar thermal power generation thermal-arrest control. The system mainly comprises a plurality of reference piles (1), a plurality of driven lens groups, a convergence lens (2) used to converge sunshine reflected by a driven lens field, and an upper computer controller (3) receiving information of deflection angle, and solar incidence angle ([alpha]), solar emergence angle ([beta]), and deflection angle ([gamma]) of each holder in real time, the information being uploaded by the reference piles (1), and the information is distributed and transmitted to a controlled driven lens group. The system can determine positions of sunlight on the convergence lens (2), the sunlight being reflected by the reference piles (1), and adjusts angles of the driven lenses according to the position, so that angles of the driven lenses are more accurate. In the control system, a sensing device is not needed to be installed on each heliostat, so cost is reduced, and maintenance ratio is reduced. The heliostat does not need to be installed in high precision, so installation and debugging speed of the lens field is improved.

Description

Technical field [0001] The invention belongs to the technical field of solar thermal power generation heat collection control, and specifically relates to a group control solar high temperature thermal power generation heat collection control system. Background technique [0002] There are two main ways to use solar energy: one is to convert solar radiation into electricity through photovoltaic cells, and the common way to use is to use solar photovoltaic cells; the second is to convert solar radiation into heat through solar collectors, the simplest is at home Rooftop solar water heaters used; the use of solar thermal energy to generate electricity has now become a key field of research at home and abroad. Its principle is to gather the sun’s rays in a pipe or container containing a certain liquid through a concentrating device. With the help of solar heat, the liquid is When heated to a certain temperature, steam is generated, and then the steam turbine is driven to generate el...
