Undisturbed Switching Control Method of Superheated Steam Temperature Systems

الملخص EN

In this paper, a new type of superheated steam temperature switching control system for thermal power plants is presented.

A single neuron adaptive PSD (Proportional Sum Differential) predictive controller is designed.

The DCS (Distributed Control System) control system platform is used for configuration design.

At the same time, the feedforward compensation technology and anti-integration saturation technology are employed to improve the characteristics of large hysteresis and multi-interference in the superheated steam temperature system.

Undisturbed switching performance can be well obtained between the new controller and its own PID controller.

This proposed method has been well applied in a thermal power plant (600MW) and achieved better control quality.
