Abstract:

Abstract:In recent years, all countries in the world improve the requirements of power system reliability, which are the power unit should have the fast cut back (FCB) function, and meanwhile it could run reliably in islanded mode and have the capability of grid reconnection. Taking the 622MW power unit of a certain power plant in Vietnam as an example, this paper introduced the optimized control strategies of the turbine speed, turbine bypass and drum water level, analyzed and solved the problems that existed in the FCB process of power unit, which ensured the normal operation and the gridreconnection capability of power unit.
