A control method and system for thermal power equipment and its circular coal yard stacking and reclaiming

Abstract

The invention discloses a control method for stacking and retrieving materials in a circular coal yard, which includes: acquiring a control instruction for coal; if the control instruction includes a stacking instruction and a retrieving instruction, decomposing the and obtain the decomposing and decomposing and decomposing and retrieving instructions respectively; the decomposing and decomposing and decomposing and retrieving instructions are sequenced; according to the decomposed and decomposed and decomposed The retrieving command controls stacking and retrieving separately. The invention also discloses a control system for stacking and reclaiming materials in a circular coal yard and thermal power equipment including the system. The above-mentioned control method for stacking and retrieving materials in the circular coal yard can realize automatic control of stacking and retrieving materials according to the control instructions for coal materials, so as to better organize coal transportation to warehouses, thereby improving the efficiency of coal transportation to warehouses, and Reduce the cost of coal yard operation.

Description

technical field [0001] The invention relates to the technical field of coal-fired power generation, in particular to a control method for stacking and reclaiming materials in a circular coal yard. The invention also relates to a control system for stacking and reclaiming materials in a circular coal yard and thermal power equipment including the system. Background technique [0002] Improving the automation level of coal yards is one of the effective ways to reduce the operating costs of coal-fired power plants. In the production organization process of stacking and reclaiming materials in the coal yard, the stacking and reclaiming of materials by the stacker and reclaimer is one of the key links in preparation for boiler combustion. [0003] In the existing technology, the coal yards of some coal-fired power stations can realize the digital control of the bucket wheel machine. For example, in the invention patent CN201810733149.9, a digital coal yard intelligent control sc...

AI Technical Summary

Problems solved by technology

However, the coal yards of some power plants are circular coal yards, and the circular stacker and reclaimer is used instead of the bucket wheel machine. The control logic has changed greatly, and the circular stacker and reclaimer has simultaneous stacking and reclaiming. In other words, the control includes simultaneous stacking and simultaneous reclaiming; secondly, at present, the control of stacking and reclaiming in the coal yard often requires the operator to manually confirm the distance and position, which will cause a large error in stacking and reclaiming. Large, which will have a certain impact on the operation of the coal yard

[0004] Therefore, how to avoid large errors in stacking and reclaiming due to the fact that the stacking and reclaiming control of the coal yard at the present stage is manually confirmed by the operator to confirm the distance and position is a technical problem that those skilled in the art need to solve at present.
