Title:
HELIOSTAT OPTICAL PATH CLOSED-LOOP CONTROL SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/007370
Kind Code:
A1
Abstract:
A heliostat optical path closed-loop control system and method, comprising a facula sensor (1), a heliostat rotation controller (2), and a computing unit (3); the facula sensor (1) is fixed on the heliostat, and rotates synchronously with the rotation of a target heliostat reflecting surface (5); the computing unit (3) is used to compute the offset between the actual position of the solar facula and the expected position, or to compute the offset between the actual and expected positions of a heliograph; the heliostat rotation controller (2) is fixed on the target heliostat; data exchange is conducted between the computing unit (3) and the heliostat rotation controller (2), and between the heliostat rotation controller (2) and the facula sensor (1). Via the use of the optical path reflection principle, the direction of an incident light or a reflecting light is controlled, achieving real time control of the heliostat orientation, effectively solving the problem of open-loop control methods being unable to make real-time corrections to heliostat orientation based on optical path feedback, realizing a real-time heliostat optical path closed-loop control system that is precise and efficient.
