Novel large-scale photo-thermal mirror field control and dispatch system based on edge calculation

Abstract

The invention discloses a novel large-scale photo-thermal mirror field control and dispatch system based on edge calculation. The system comprises heliostat real-time tracking controllers, a heliostatgroup controller, a data server and a control server, wherein the heliostat real-time tracking controllers comprise a first control module, a heliostat body, a driving module, a basic IO module and afirst power module, the plurality of heliostat real-time tracking controllers form a heliostat controller group, the heliostat group controller comprises a second control module and the power module,the control module 2 is connected to the plurality of heliostat real-time tracking controllers through the carried four Can bus communication networks or an LTE wireless private network module, and the heliostat group controller accesses a data server and a control server through the dual-redundant Ethernet network. The system provided by the invention has the advantages of layered control, datamanagement, high reliability of system communication, accurate calculation and summary storage of real-time transmitted data.

Description

technical field [0001] The invention relates to the technical field of automatic control and solar energy instant heating system, in particular, a novel large-scale photothermal mirror field control and scheduling system based on edge computing. Background technique [0002] Solar thermal power generation and high-temperature heat utilization are new and efficient ways for people to use solar energy natural resources. Through large-scale mirror fields to focus solar energy, high-quality heat sources can be formed, which can be used for photothermal power generation or high-temperature heat utilization. Compared with other renewable energy sources, solar thermal has its advantages: it can be continuously adjusted, so that it can participate in the peak regulation and frequency regulation of the power grid; it can store large-scale and low-cost energy, and the current cost of heat storage is one hundred of the cost of chemical electric energy storage Thirty-one thirds; it is t...

AI Technical Summary

Problems solved by technology

At present, traditional control systems, such as PLC and DCS systems, cannot be well used for the control of large-scale mirror fields, because mirror fields have their own characteristics different from other process control objects: many nodes, large amount of data, security and High real-time requirements and strict requirements on the environment

Ordinary control systems cannot meet the requirements of actual production at all
