Application of Improved EADRC in Superheated Steam Temperature Control of Supercritical Thermal Power Unit

Against the backdrop of the continuous and rapid development of new energy power, the power grid demands thermal power units to have a wider load regulation range and higher load regulation rate. This poses a great challenge to the control of superheated steam temperature (SST). To address this, an improved error-based active disturbance rejection controller (IEADRC) is proposed, combined with the modified northern goshawk optimizer (MNGO), to enhance the control performance of SST in supercritical thermal power units. Firstly, structural improvement is introduced to the error-based active disturbance rejection controller. Then, the northern goshawk optimization algorithm is enhanced and applied to the parameter optimization of IEADRC. Finally, simulation experiments on the SST control system demonstrate the excellent control performance and disturbance rejection capability of the designed integrated control strategy.
