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

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.
