Abstract: Aiming at a certain power plant with the XDC-800 DCS system, When the block turbine main control instruction, transformed by primary frequency modulation homologous device, increase or decrease, the turbine main turbine change suddenly. Based on the control loop simulation analysis, this paper puts forward the logic optimization measure, which Provides a reference for block increase or decrease of the same DCS system design control loop.
Key words: primary frequency modulation, EPID, DEH, CCS, block, simulation, scan cycle
