The Application of Three Impulse Cascade in Drum Water Level Control System

Article Preview

Abstract:

Steam boiler supplies steam of certain quality in industry process according to the changes of load. It is important of most power plants and has been concerned with analyzing power system dynamics in various works. Drum water level is one of the main processes in the boiler. Because of the phenomenon of false water level, three measurement signals including drum water level, water supply flow and steam flow are introduced. In this paper three impulses Cascade control system with fuzzy PID control is presented, and simulation is performed based on MATLAB.
