水电站自动化元件及自动化

Automation and Automatic Components of Hydropower Station

随着水电站自动化水平的提高,水轮发电机组所需自动化元件愈来愈多,其作用就愈重要。但由于目前主机配套的自动化元件的性能不够稳定、灵敏度差、精度低等因素以及自动化设计上的不足,使水电站的自动控制的安全受到不同程度的影响。本文根据近年来几个电站的安装运行实践提出几点看法,以供参考。

With the promotion of automation level,more automatic components of the water turbine-genera- tor set at a power station are needed and their roles are becoming increasingly important.But at the pres- ent time the safety of automatic control is somehow affected by the unstable performance,insensitiveness and inaccuracy of the main unit′s kit components,or by the unadequate design for automation.After hav- ing looked into the current situations of several stations that have been installed and run in the past few years the author of the essay has put forward some constructive opinions for referrence.
