APPLICATION OF OPTIMIZED CONTROL SYSTEM PROFI IN DINGZHOU POWER PLANT

In order to make large-capacity units to participate into peak-load regulation in the power grid,the optimized control system PROFI,which was designed and manufactured by Siemens AG,has been used for 2×600 MW units in the first-phase project of Guohua Dingzhou Power Plant,and the coodinated and adoptive temperature control modules of the units being optimized in PROFI.Through modification of control strategy in DCS,the control scheme in PROFI and the original control scheme in DCS have been combined together,make the control system to have higher stability and better dynamic response character.
