| 摘 要： | 介绍了一种应用于塔式太阳能热发电系统中的腔式水/蒸汽吸热器给水全程控制系统。提出了系统运行对控制系统的控制要求,给出了吸热器的给水压力控制系统和给水泵转速控制系统的设计和研制方法。同时指出,为了避免两个系统之间的互相干扰,使各系统尽可能地协调动作,在给水压力控制系统中引入了水泵转速偏差前馈信号,在转速系统中引入压力偏差前馈信号,使系统的给水压力调节和给水泵转速控制互相联系起来,加快汽包水位的调节速度。

| Abstract: | 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. |
