| Abstract: | A theoretical line loss rate prediction method is built based on continuous hidden Markov model. Baum-Welch parameter re- valuation correction formula is applied for CHMM parameters optimization. It judges the effectiveness of each optional simulation model relative to actual system according to the probability output of CHMM model. The result shows that the model is speedy and with high accuracy in theoretical line loss rate prediction. |
