An Elman neural network optimized by particle swarm optimization( PSO) algorithm was introduced to establish the vacuum prediction model for dual-pressure condensers. The calculation model which can forecast both the high pressure and low pressure side of the dual-pressure condensers was proposed. Moreover
the above model was applied in dual-pressure condenser in a 600 MW unit and the results were compared with that predicted by the common algorithm-modified Elman neural network. The results show that
this Elman neural network optimized by PSO algorithm has faster convergence speed and higher accuracy
which is a feasible model for vaccum prediction in dual-pressure condensers.
