Embodiment Construction

[0024] DUTGK-11 thermal power plant boiler automatic control system:

[0025] This system realizes computer control of 3 furnaces in the thermal power plant. The computer controls the combustion of the boiler according to the load change of the generator, so that the steam flow generated by the boiler meets the requirements of the steam turbine. This system uses the control system of each furnace to connect the data acquisition system 2, alarm output and control system 3, and real-time Ethernet interface 4 with the industrial control computer 1, and connects the real-time Ethernet interface 4 and the data communication network 5. The data communication network 5 is connected to other road control systems.

[0026] Input the standard value of the given steam drum pressure, select the coal type of fuel used, and the system will automatically select the neural network of the coal type in the multi-type coal type neural network, or calculate the primary air volume required by the ...

Abstract

Boiler intelligent control system and its multi-kind coal controlling means belong to the computer management and control technical field, comprising data collection system, intelligent controller and warning system, industrial control computer,, data communication network, long-distance monitoring service, real-time Ethernet interface, data management system and different kinds of coal burning calculation and management system, especially real-time Ethernet interface and 'fixed furnace / movable furnace model have solved data transmission and multi- furnace teamwork problem; the multi-kind coal controlling means is, after entering the chosen kind of coal, the system will automatically choose its neuronic network or calculate the first wind rate, the second wind rate and fuel quantity with different load, build the initial neuronic network and learn online, realizing the boiler controlled automatically, changing and satisfying manufacturing parameter requirement also, adding long-distance monitoring service, increasing production management level.

Description

technical field [0001] The invention belongs to the technical field of computer management control. Background technique [0002] The boiler control work of the power plant is very labor-intensive and very important, and it is the main link of power generation in thermal power plants. It requires the fireman to monitor the combustion situation of the boiler at all times, and control and adjust the combustion of the boiler according to the corresponding situation, so as to achieve the effect of saving, safety and stability. At present, most of them have realized automatic control. However, the price of fuel is constantly changing, and the coal purchased in each period is different. Sometimes several types of coal may be mixed to reduce power generation and heating costs. Correspondingly, the control quality of boiler combustion will decline, making the whole system very unstable, and the possibility of accidents will also increase. In addition, when multiple furnaces are ...
