Abstract

The invention discloses a control method for a distributed control system. The control method comprises the following steps: acquiring historical operation data of a unit; according to the historicaloperation data, establishing a corresponding relationship between the actual output quantity and the historical control parameters under different historical conditions; searching a corresponding target historical control parameter when the target condition is consistent with the historical condition and the actual output is the target output according to the corresponding relationship, and takingthe target historical control parameter as a current control parameter; and generating a control instruction according to the current control parameter, and sending the control instruction to a distributed control system of the unit. Therefore, the setting process of human intervention control parameters is avoided, and time resources and human resources are greatly saved; moreover, the setting accuracy of the control parameters is improved, and the requirements of an operator are better met. In addition, the control device and equipment for the distributed control system and the storage medium provided by the invention correspond to the method.

Description

technical field [0001] The invention relates to the technical field of coal-fired power station control, in particular to a control method, device, equipment and medium for a distributed control system. Background technique [0002] my country's energy composition is dominated by coal, and coal-fired power stations currently account for about 60% of all power generation. In a thermal power plant, the unit can be controlled according to factors such as the required unit load and grid frequency to respond to relevant adjustment requirements and ensure safe, stable and economical operation of the unit. [0003] In general, when it is necessary to ensure that the unit load reaches a certain value, the power plant control system sends unit load commands to the distributed control system (DCS) of the unit, to the distributed control system of the boiler and the distributed control system of the steam turbine, and then to the distribution control system of the fuel. The distribute...
