Application of Hot Redundancy PCC System in Speed Governor of Large Pumped Storage Power Station

A governor control system which is suitable for large pumped storage power station is introduced in this paper. The above system is based on the fundamental characteristics of hot redundancy, its hardware kernel consists of B＆R2005 series PCC modules and intelligent switching unit with the strict dual redundancy and switching logics designed and its successful application has already been obtained in some large pumped storage power stations. By means of the experiments for the static characteristics and dynamic regulations on the site, these indicate that the system is of high regulation precision and steady dynamic process, it is able to satisfy the demands of operating conditions switching, accurate control and higher reliability for large pumped storage power station, and its popularization and application could be implemented in our country.
