Tower-type solar heat collection heliostat field control system based on multi-layer architecture

Abstract

The invention relates to a tower-type solar heat collection heliostat field control system based on a multi-layer architecture. The system is composed of three control levels including a heliostat field scheduling and controlling layer, a heliostat sub-group controlling layer and a sun tracking device layer from top to bottom, wherein the heliostat field scheduling and controlling layer consists of five parts including a heliostat field controlling machine, a weather monitoring device, a field observation device, a communication interface and a light spot checking device; the heliostat sub-group controlling layer is composed of a controller adopting the two-computer backup redundancy technique, and the controller has the function of a bottom-layer heliostat; and the sun tracking device layer consists of the bottom-layer heliostat used for open-loop control and open-loop / closed-loop mixed control.

Description

technical field [0001] The invention relates to the fields of tower solar heat collection systems and industrial automation control, in particular to a tower solar heat collection heliostat field control system based on a multi-layer structure. Background technique [0002] With the market's increasing demand for clean energy, a large number of solar tracking devices that mainly track the sun's orbit have emerged in the field of solar thermal power generation. Among them, the tower solar thermal collection system is higher than other systems such as the trough system and the butterfly system in terms of tracking complexity and precision requirements. Moreover, the tower solar heat collection system has fully demonstrated its superior economic and technological development prospects, which is of great significance for promoting the development of renewable energy. [0003] Tower solar heat collection system technology and equipment are in the early stage of marketization and...

Problems solved by technology

[0005] 1. In the prior art, there is no system for controlling the heliostat field combined with large and small spots;

[0006] 2. At present, heliostat controllers usually use expensive bottom-level control units and devices with general functions, most of which are unnecessary functions in the heliostat control process, resulting in waste of resources and not suitable for industrial production and market competition ;

[0007] 3. The heliostat group controllers in the heliostat field have high performance, and there is still room for development and utilization

In the prior art, it is only used as a special subgroup controller, which causes a waste of resources;

[0008] 4. The existing open-closed-loop hybrid control heliostat device based on the photosensitive sensor cannot be adjusted in real time due to the direction pointed by the photosensitive sensor, and some light spots of the mirror field cannot be projected to different positions of the heat collector to realize the monitoring of the surface of the heat collector.
