Feedwater Control System Design of Cavity Type Solar Water/Steam Receiver
Feedwater control system of a cavity type water/steam receiver for solar power tower plant was introduced,as well as control requirements of feedwater control system were put forward.Besides,feedwater pressure control system of receiver and speed control system of feedwater pump were designed and developed.At the meantime,in order to avoid interference with each other between two systems and make two systems cooperation in harmony,speed deviation feed-forward signal of feedwater pump was imported to feedwater pressure control system,and pressure deviation feed-forward signal was add to speed control system.By using above mentioned methods to make adjustment for feedwater pressure and speed control of feedwater pump combined and cooperated,so that adjustment speed for drum water level can be quicken.
