Main Steam

Main steam temperature regulation is one of the most demanded control loop in modulating control system of thermal power plant. According to the characteristics of main steam temperature, an intelligent control technology has been proposed. To eliminate lag and inertia in main steam temperature regulation process, the intelligent control technology integrates several advanced algorithms. The application effects in several ultra-supercritical thermal power plants prove that the control technology has outstanding robustness and excellent adaptability in both variable load and steady state condition.

Main Steam

In large-scale thermal power plants, the control of boiler main steam temperature functions as an indispensable part to improve the economic efficiency and ensure the unit’s safety. Currently, the main steam system is always characterized as a dynamic system with big delay, large inertia and huge uncertainties. Considering the characteristics above, the Active Disturbance Rejection Control (ADRC) is designed and serves as a creative solution to the problem of main steam temperature control. In this paper, a guiding temperature signal is adopted as an auxiliary feedback signal, which constitutes the cascade control loop of ADRC-PI.
