在线组态调门开启逻辑减小汽轮机组大轴振动

On-line Confi guration the Logic of Regulating-valve Open Sequence Reducing the Vibration of Turbine Axle

通过对大唐安阳发电有限责任公司#9机组大轴振动情况的分析,在线组态DEH逻辑改变调门开启顺序,减小汽流扰动作用力的影响,改善了机组振动情况,提高了机组的安全性、经济性和出力能力,取得了较好的经济效益和良好的社会效益。

This article introduces the vibration of turbine axle of Datang Anyang power plant No.9 unit. It introduces how to on-line configuration the logic of regulating-valve open sequence to reduce the impact of steam disturbance and the vibration of turbine axle, Such configuration not only improve the security, economics and working ability of the Units but also Obtain better benefit of economics and society.
