Abstract

Abstract: The equipment control strategy of protection system of ultrasupercritical steam turbine was expounded. The signal processing and operation principle of each protection circuit were introduced. According to several times tripping of the steam turbine, the problems existed in the system were analyzed, the improving scheme was put forward to raise the unit economical efficiency.
