Directing against the thermaldynamic system of one co-generation unit in the self-supplying power plant under Taiyuan Iron Steel(Group) Co Ltd

the relational expression of units characteristics and the model for optimization of thermal and electrical load distribution for said co-generation unit have been established

through optimized calculation of data in operation of said unit

it shows that the load distribution optimization can save steam 47.83 t/h as comparaed with the traditional operation.In addition

the method for thermal and electrical load distribution optimization of the said co-generation unit has been put forward.
