浅析清原抽水蓄能电站机组自动控制系统

The summarize of Qingyuan Pumped Storage Power Station unit automatic control systems

摘要

通过介绍清原抽水蓄能电站水轮机及发电机辅助控制系统、调相压水控制系统、进水阀控制系统等自动化控制系统的功能描述，阐述电站中对于导叶开度、转速信号装置、控制回路电源设置原则及其他方面的设计内容，以便于了解并掌握这些与机组运行密切相关的自动化控制系统的控制原理及重点问题，对后期其他抽蓄电站相关系统的设计具有借鉴意义。

Abstract

The auxiliary control systems for hydraulic turbines and generators, the condenser dewatering system, and the spherical valve control system about Qingyuan Pumped Storage Power Station are decribede in this artical. It is also introduced the design of the guide vane opening, the rotational speed measurement, and the power supply principle for controlling circuit. Through these introduction and summary, it is easy to understand and master the control principles and the key issues of the automatic control system, which is closely to the daily operation of this power station. The result provide a basis and reference to the design of the upcoming pumped power stations.
