| Self-adaptive control has good robustness, high regulating speed and excellent anti-interference. The combustion system of the supercritical unit is a complex nonlinear time-varying system. Considering the characteristics of the combustion system of the supercritical unit in the thermal power plant, the self-adaptive control system is adopted to realize optimal control over the boiler combustion system to ensure high efficiency and stability of system operation. The simulation results show that this method can effectively handle the coupling between system variables. Control can be realized according to current load variation so that effective regulation of the main steam pressure can be made quickly in a steady and accurate way to ensure sufficient combustion of fuels to maintain furnace draft within the specified range. In the case of changes of coal quality and equipment characters, the system can operate steadily and the combustion efficiency is increased greatly. This method can maintain the complex production process in optimal operation, reduce coal consumption and ensure system security and reliability. |
