The Operation Analysis And Best Project Confirm In Many Heat Sources Joint Operation Of Heat-supply Networks

The technique of joint operation of heat-supply networks of many heat sources is developed in the foundation of synthesize the application of adjusting soon technique and controling technique of pump as to economize the energy, lower the system movement cost and increases economic performance in the abroad countries that have advanced heat-supply. To compare with abroad, our country's centralized Heat-supply has a certain margin because of starting than night. In the paper ,we regard the heat-supply networks of Hrbin airport development area as the research object, concretely analysis the heat-supply networks conditions of taking off operation an joint operation of heat-supply networks. How to make the circulation excellent turning in the condition of joint operation, to confirm the project of the best movement and contrastly analysis between them.In the paper, it resolve hydraulic calculation equilibrium calculation problem of ring-shaped heat-supply network making use of network diagram theory, and improved the compute accuracy. Discussed how assign the space-heating load among the many heat sources, how time that heat source start with and how many days they operate, and the problem about hydraulic remit to order in the hool net. The above problem constituted the best project of joint operation of heat-supply networks. At the same time, it check hydraulic calculation of conditions of taking off operation an joint operation of heat-supply networks of the stages of forward and near period in the heat-supply networks and combine proceeding expenses analysis comparison.In the paper, it analyzed the shortage exsited in the heat-supply networks ofHrbin airport development area by hydraulic calculation. That have a certain meaning to the operation of this heat-supply networks.
