Dynamics of feed water flow rate control system with low- noise regulator
No full textWe present the results of modeling a feed water control system. The system contains two regulatory devices the feed valve to control the flow rate, with electrohydraulic control, and the throttle valve to maintain constant pressure differential on the feed valve, with hydromechanical control. The valves have perforated flow parts to reduce hydrodynamic noise and vibration, which necessitates checking the dynamical characteristics of the system. The model was developed on the basis of equations describing the electrohydraulic converter dynamics, a differential pressure meter, a servo drive and flow parts with the use of Matlab Simulink. The modeling of dynamical processes caused by various disturbance inputs and control actions showed the compliance of the system with the requirements imposed on it
