| 摘 要： | 以具体工程项目为实例，提出了改进的300MW火力发电厂全程给水调节方案，并详细介绍了其实现过程。该方案能够实现给水系统从低负荷到高负荷所有的自动控制，免除了复杂的人工操作，并能在给水系统的主路和旁路的切换中最大限度地消除对汽包水位的扰动。

| Abstract: | A project was taken as an example and its improved control strategy for whole processes feed water automatic control system in 300MW thermal power plant was proposed. Its realization process was also described in detail. With the new control strategy ,the feed water system can be controlled automatically from low load to high load. Thus the manual work will be relieved.And the fluctuating of drum water level also can be avoided during the switching between bypass main road of water system. |
