| 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. |
