• The design scheme of the automatic power plant start-up and shut-down system (APS) in Haimen 1 000 MW ultra-supercritical units is introduced. The stratified control structure and the breakpoint manner are used in order to simplify the system design and fit the different operation modes. The breakpoints setting and breakpoints functions during start-up and shut-down are introduced. The global control strategy of the main analog control system during the process of the unit's start-up is illustrated. The scheme and analog control strategy have been successfully used in the start-up and shut-down process of the 1st and 2nd units in Haimen Plant, where the subsystems automatically in and out during the start-up and shut-down is realized, especially the undisturbed switch of coordinated control system during the transfering process from wet to dry and from dry to wet is implemented successfully. The rationality of the overall design and control strategy is verified. It is valuable to design and development of APS
