Abstract
Based on chaotic theory and related research methods
and directing against data sequence materials of reheated steam tempe-rature for one thermal powergeneration unit
the parameters
such as correlational dimensions and the max. Lyapunov index
representing characteristics of the reheated steam have been calculated by using the phasespace rebuilding technology
the chaotic dynamics performance of the reheated steam temperature being revealed
providing new thinking for establishing the reheated steam temperature model and for accurate prediction of the said temperature.
