Embodiment Construction

[0043] The embodiment of the present invention provides a method for quickly switching the mirror field, which is used for the mirror field switch of the tower solar thermal power generation system, including the following steps:

[0044] Before the opening of the heliostat, turn the heliostat of the mirror field to the first-level opening posture;

[0045] Switching the heliostat from the first-level opening attitude to the operating sun-tracking attitude;

[0046] Turn the heliostat to the first-level closing position before the heliostat is closed;

[0047] Switching the heliostat from the first-level off-field attitude to an end-off attitude.

[0048] Wherein the process of switching the heliostat from the first-level opening attitude to the operating sun-tracking attitude includes:

[0049] Obtaining the trajectory of the spot falling point when the heliostat is switched from the first-level opening attitude to the operating sun-tracking attitude;

[0050] Obtaining th...

Abstract

The invention provides a method for rapidly opening and closing a mirror field. The method for rapidly opening and closing the mirror field is used for opening and closing the mirror field of a tower type solar thermal power plant and comprises the steps that a heliostat of the mirror field is switched to a first-stage field opening posture before field opening of the heliostat; the heliostat is switched to an operation sun-tracking posture from the first-stage field opening posture; the heliostat is switched to a first-stage field closing posture before field closing of the heliostat; the heliostat is switched to a field closing finishing posture from the first-stage field closing posture. Through scientific scheduling of the mirror field when the mirror field is opened and closed, the method for rapidly opening and closing the mirror field guarantees the safety of a heat absorber to the maximum extent, shortens the time for opening and closing the mirror field, lowers the cost of spare batteries, and increases the actual operation power generating time of the mirror field.

Description

technical field [0001] The invention relates to the field of tower solar energy, in particular to a method for quickly switching mirror fields. Background technique [0002] The tower solar thermal power generation system is different from the solar photovoltaic power generation system. It is a kind of Concentrating Solar Power (CSP for short). The heat absorber on the tower heats the working fluid, generates steam, and drives the steam turbine to drive the generator to generate electricity. Compared with photovoltaic power generation, the tower solar thermal power generation system not only has no pollution in raw materials and production processes, but also has a heat storage device, and the power generation is relatively stable. It is welcomed by the power grid and is a truly clean and high-quality energy source. Compared with the trough-type solar thermal power generation system, the tower-type solar thermal power generation system has a higher concentration ratio, and ...
