Abstract: With the development of heating systems in scale,complexity and intelligent level,hydraulic calculation considering multiple time-dynamic conditions and the spatial information of the whole network are used in heating network analysis,which plays a key role in scientific decision-making and operation scheduling for heating companies.Based on the analysis and verification on the hydraulic conditions for the whole network in a heating company,a time-space analysis method adapting to the local condition is proposed.Dealing with a muti-condition operation plan including network-cutting condition,multiple heat source networking and distributed variable frequency transmission,an optimized operation plane is carried out according to the topological structure of the current pipelines. It can improve the safety and economy of the hydraulic operation of the whole network.
