Produce the operation conditions of consumption link and use the scheduling present situation grid model to be carried out the diagnosis and the evaluation of aspects such as system configuration, system performance and traffic control in conjunction with the optimum adapted principle of combustion gas, combustion gas.
Produce the consumption operation conditions and use the scheduling present situation vapour system network model to be carried out the diagnosis and the evaluation of aspects such as system configuration, system performance and traffic control in conjunction with each link steam quality demand, steam.Concrete adopt " the reasonable adapted of steam grade ", " steam rationally uses " and reasonable recovery and utilization that principles such as " the reasonable efficient power generation of steam (distributed and centralized take all factors into consideration choice) " is carried out steam to diagnose nearby.
The water system network model is carried out the diagnosis and the evaluation of aspects such as equipment disposition, equipment performance and traffic control in conjunction with each link water quality requirement, water yield requirement, water system operation conditions and use scheduling present situation.
The supply and distribution network model is carried out the diagnosis and the evaluation of aspects such as equipment disposition, equipment performance and traffic control in conjunction with operation of power networks situation and use scheduling present situation.Moreover, supply policies such as distribution management, charge in conjunction with integrated iron and steel works from power backup level and country, implement the optimum diagnosis that integrated iron and steel works' Integrated Energy is recycled (providing still other purposes of generating for oneself).
More than explanation only is one embodiment of the present of invention, can not limit the present invention, and every those of ordinary skills as long as be included in the claim scope of the present invention, belong to the scope of the present invention's protection to the equivalence replacement that the present invention carries out.
