| Abstract: | Water level influence to high pressure steam drum caused by sudden change of steam charge and water flux is introduced in detail. The disadvantage of traditional single -element and dual-element in overcoming false water level and feed water disturbance is analyzed deeply. Design plan and parameter calculate method of three-element control system to special device are given out. The configuration of this control system is introduced simply. |
