Method for controlling heliostat to automatically follow track of sun in tower type solar energy thermal power generation

Abstract

The invention provides a method controlling a heliostat to automatically follow the track of the sun in tower type solar energy thermal power generation, which uses a DPU controller controlling the motion route of the heliostat, an execution mechanism connected with the heliostat and a DCS module performing the communication conversion of transmitted data between the DPU controller and the execution mechanism to allow the heliostat to move to automatically follow the track of the sun. The method can allow the heliostat to accurately and automatically follow the motion track of the sun, maximize the solar energy radiated onto the surface of the heliostat, improve the heat collection efficiency of a light condensing system and greatly improve the power generation efficiency of a power plantand reduce the operation cost of the power plant.

Description

Control method for automatic tracking of sun trajectory by heliostats in tower solar thermal power generation technical field The invention relates to solar thermal power generation technology, in particular to a control technology for enabling heliostats to automatically track the sun's trajectory in a tower-type solar thermal power generation system. Background technique Traditional fuel energy is decreasing day by day, and the harm to the environment is becoming more and more prominent. At this time, the whole world is turning its attention to renewable energy, hoping to change the human energy structure and maintain long-term sustainable development. Among them, solar energy has become the focus of people's attention due to its unique advantages. Abundant solar radiation energy is an important energy source, which is inexhaustible, non-polluting, cheap, and can be used by human beings at will. The energy of solar energy reaching the ground every second is as high as 8...

Problems solved by technology

In the prior art, the calculation of the motion trajectory of the heliostat is concentrated in the intelligent actuator or the local PLC. Compared with the intelligence of the present invention, such a control method has limitations, and the completed functions are also limited. limited, so the control accuracy is very low
