Abstract: Starting from the principle of sliding pressure curve, the practical operation data of unit, the thermodynamic theory and safety of operation regulation, the problems in automatic sliding pressure optimized curve was found. Through the analysis of the influence of the attemperating water quantity on reheater, the suitable safety and economical operation mode was found, and the unit automatic sliding pressure operation was realized. Then the safety and economical efficiency of the unit had been enhanced.
