The article is devoted to the analysis of the technological process of heat load control and cost-effective fuel combustion in furnaces of drum steam generators at a thermal power plant. The object of automation – boiler unit type “Е-75-3,9-440G” – is analyzed. The mathematical model of fuel and air supply system to the steam generator is developed according to installed equipment characteristics. The model’s parameters are calculated. The actuating element of the system is an electric single-turn mechanism designed to actuate shut-off and control valves in the fuel and air supply channels. Two-channel control system is synthetized for providing an optimal ratio of fuel and air consumption with oxygen content correction in the flue gases. The automatic control system model is realized in Matlab application package, Simulink programming environment. The achieved results show the right settings for cascade control system. In conclusion, an example of the necessary technical equipment complex is listed for technical implementation of the developed control system.

Loop Feedback

The production process of the thermal power plant is transferring primary energy to secondary energy. Loss of energy is quite large for coal machine. When using air supply machine and other boiler auxiliary equipments, saving energy, reducing energy consumption is an important way to reduce the cost. This paper first analyzes the basic principle of energy transformations generation field and principle characteristics of thermal automatic control system during the production process. On the basis of energy saving and low cost framework, according to the single loop feedback construction, we establish automatic control system model of thermal power plant. Through comprehensive cloud generator we do simulation on thermal power enterprises, the result is significant. It shows that this model can provide scientific theoretical basis for the operation mode of power generation enterprises in a certain degree.
