Heliostat driving and controlling integrated controller and control method

Abstract

The invention relates to a heliostat driving and controlling integrated controller. The heliostat driving and controlling integrated controller comprises a control module, a motor driving module and an input and output module. The control module is used for controlling the motor driving module based on settings and instructions of an engineer station, collecting motor rotating speed and angle information through the input and output module to obtain current gesture information of the heliostat, and sending current gesture information feedback of the heliostat to the engineer station. The motordriving module is used for driving a motor in the azimuth and pitching direction of the helioscope based on instructions of the control module. The input and output module is used for collecting information of a motor encoder and a sensor in the azimuth and pitching direction. The motor encoder is used for detecting current angle information of the heliostat in the azimuth and pitching direction.Driving and controlling integrated design is adopted for the controller, reliability of the heliostat controller is improved, and the cost and complexity of the controller are greatly reduced.

Description

technical field [0001] The invention relates to the field of solar thermal power generation, in particular to a heliostat drive-control integrated controller and control method. Background technique [0002] Tower-type solar thermal power generation is mainly composed of three parts: heliostat concentrating system, heat absorption and heat transfer system, and power generation system. The heliostat is the core component in the tower solar thermal power station, which concentrates and reflects the solar radiation to the heat absorber to heat its working fluid. The concentrating field composed of heliostats is usually composed of tens of thousands of heliostats, and the number is huge. How to control a large number of heliostats with high reliability to track the sun accurately and quickly is the key core to ensure the efficient and safe operation of the power station technology. a. et al mentioned a PLC-based heliostat control system in the literature "Heliostat orientati...

AI Technical Summary

Problems solved by technology

The PLC control system includes: PLC controller, driver, data acquisition unit and power supply, etc., and the cost is relatively high

In addition, this type of control system reduces the reliability of the overall control system because it contains multiple equipment units.

At the same time, this type of control system only allows one programming environment, which greatly reduces the secondary development, compatibility and scalability of the system.

[0003] To sum up, the existing heliostat control system mainly adopts PLC and driver combination system, including: PLC controller, driver, data acquisition unit and power supply, etc., and the cost is relatively high

In addition, because this type of control system contains multiple equipment units, the cost is high, and the reliability of the overall control system is reduced.

At the same time, this type of control system only allows one programming environment, which greatly reduces the secondary development, compatibility and scalability of the system.
