Analysis and study on dynamic property of boiler and turbine

as well as on the control strategy of direct energy balance （DEB）

signal of energy balance

and main steam pressure regulation have been carried out

an effective practical control system for coordinated control of turbine and boiler being designed

and applied in actual project of engineering. The said system not only improved control quality of the controlled variables

enhanced capability of the coordinated control system to suit load variation

but also reduced the amount of debugging work in the field.
