Embodiment 1

[0058] Such as figure 1 As shown, this embodiment takes an intermediate network structure as an example, and several first execution scheduling controllers 3 and first gateways 4 of the intermediate network structure form a ring network structure, and each first execution scheduling controller 3 corresponds to a group The heliostat controller 1 and the first execution scheduling controller 3 are connected and communicated with the first switch 5 through the first gateway 4 , and the first switch 5 is directly connected and communicated with the upper computer server group 2 . The upper computer server group 2 communicates with the heliostat controller 1 through the intermediate network structure, so as to issue control commands to the heliostat and control the action of the heliostat.

[0059] The upper computer server group 2, the first gateway 4 and the first switch 5 of the present embodiment are all provided with a redundant structure, and the upper computer server group 2...

Embodiment 2

[0063] Such as figure 2 As shown, the present embodiment takes two intermediate network structures as an example. On the basis of Embodiment 1, a second intermediate network structure is added. The two intermediate network structures are connected in series, and several second execution scheduling controllers 6 and the second gateway 7 form a ring network structure, the second gateway 7 is communicatively connected to the second switch 8 , and the first execution scheduling controller 3 in the first intermediate network structure is communicatively connected to the second switch 8 .

[0064] The rest of the first execution scheduling controllers 3 in the first intermediate network structure may also radiate a plurality of intermediate network structures, which are not shown in the figure. The network coverage of the heliostat mirror field control system in this embodiment is wider, and more heliostat controllers can be connected to save costs.

Embodiment 3

[0066] Such as image 3 As shown, the present embodiment takes three intermediate network structures as an example, which is to combine one intermediate network structure in Embodiment 1 with two intermediate network structures connected in series in Embodiment 2, and combine Embodiment 1 The intermediate network structure in the embodiment 2 is connected in parallel with the intermediate network structure in Embodiment 2, and is controlled by the same host computer server group.

Abstract

The invention discloses a heliostat field control system which comprises a plurality of controller sets, at least one intermediate network structure and an upper computer server set; wherein the controller set comprises a plurality of heliostat controllers and each heliostat controller controls one heliostat correspondingly. The intermediate network structure comprises a gateway, a switch and a plurality of scheduling executing controllers. The plurality of scheduling executing controllers and the gateway form the annular network structure or the star-shaped network structure. The scheduling executing controller is connected with and communicates with the switch through the gateway. The scheduling executing controller is connected with and communicates with the controller set. The switch is connected with and communicates with the upper computer server set. The heliostat field control system according to the invention has functions of realizing overall planning scheduling and diversified control for the heliostats in the whole heliostat field, preventing fault spreading and improving reliability of the control system.

Description

technical field [0001] The invention relates to the field of tower-type solar thermal power generation heliostats, in particular to a heliostat field control system. Background technique [0002] As a clean and renewable energy, solar energy has been applied more and more, especially photothermal power generation technology is an emerging solar energy utilization technology after photovoltaic power generation technology. Among several photothermal power generation technologies, tower-type solar thermal power generation uses a large number of heliostats to gather sunlight to the heat absorber installed on the top of the heat-absorbing tower, heats the working medium, generates steam, and drives the steam turbine to drive the generator. generate electricity. Among them, since the entire tower-type solar thermal power generation heliostat mirror field contains thousands of heliostats, the precise control of each heliostat is realized, so that the heliostats can maximize the re...
