Heliostat field control system of tower type solar power plant

Abstract

The invention discloses a heliostat field control system of a tower type solar power plant. The heliostat field control system comprises a plurality of upper computers, a plurality of heliostat flight controllers, a plurality of heliostat set controllers, a plurality of heliostat controllers and a plurality of heliostats, wherein the plurality of heliostats are arranged in multi-line way, each line is divided into a plurality of groups of heliostats, and each group comprises a plurality of heliostats; each line of heliostats is correspondingly provided with a heliostat line controller, each group of heliostats is correspondingly provided with a heliostat set controller, and each heliostat corresponds to one heliostat controller; and the upper computers are connected with all heliostat line controllers which are connected with the plurality of heliostat set controllers in the corresponding line, the heliostat set controllers are connected with the plurality of heliostat controllers in the corresponding group, and each heliostat controller is connected with one corresponding heliostat. The heliostat field control system of the tower type solar power plant is suitable for mirror filed control of tens of thousands of heliostats, so that principles of decentralized control and centralized management are maximally embodied; and the heliostat field control system of the tower type solar power plant is high in reliability and usability.

Description

technical field [0001] The invention relates to the field of tower-type solar thermal power generation heliostats, in particular to a large-scale heliostat field control system in a tower-type solar thermal power generation system. Background technique [0002] Tower-type solar thermal power generation technology uses heliostats to track the sun, so that the reflected light can be accurately projected onto the heat exchange surface of the heat absorber placed on the top of the receiving tower. The heat absorber converts sunlight energy into heat energy and heats the inside of the coil The flowing medium (water or other fluid) generates medium and high temperature steam to drive the turbogenerator to generate electricity. The Badaling tower-type solar power experimental station that has been built so far is the largest tower-type solar thermal power station that has been put into operation in China, with an installed capacity of 1MW. There are more than 100 heliostats install...

Problems solved by technology

The Badaling tower-type solar power experimental station that has been built so far is the largest tower-type solar thermal power station that has been put into operation in China, with an installed capacity of 1MW. There are more than 100 heliostats installed in the whole plant. The entire power plant investment is 92%, the cost is too expensive, and the efficiency of the control system is not high, which greatly restricts the commercial application prospect of this technology
