Abstract

Abstract: In this paper, the system configuration and control logics to realize the FCB function of 660-MW units in Ningxia Ningdong Power Generation Co. Ltd. are introduced, and the analysis on the abnormality of higher speed rise in “island operation” FCB test than that in“convention” FCB test in Unit 1 is conducted. Consequently, the optimization on related control logics and parameters is proposed so as to successfully conduct the subsequent “island operation” FCB test of Unit 2.

Key words: fast cut back (FCB), island operation, over speed protection control(OPC), maximum transient speed, temporary speed rise, temporary soaring acceleration
