Abstract: In this paper, taking the 660-MW ultra supercritical unit with second reheat cycle of Anyuan Power Plant as the study object, through the analysis on the static characteristics with single factor variation of reheat steam temperature controls, the control schemes of primary and secondary reheat steam temperatures are proposed. The onsite operation practices show that the schemes can meet the operation requirements under various loads and RB working conditions.

Key words: automatic control, reheat steam temperature, secondary reheat, flue gas recirculation
