摘　　要：山东省某市现主力热源为城外南郊区热电厂,城区内热源作为应急备用热源,下个采暖季将在供热系统高点新增一热源对城区进行供热。由于两主力热源高差达58 m,为分析新热源接入现有供热系统后的水力工况,利用水力计算软件建立了全网计算模型,进行两热源并网运行、切网运行多种工况下水力计算分析系统运行可行性及相应解决方案,确定下采暖期两热源采用切网运行方式,并明确了两热源相互补充范围。该分析路线对类似多热源联网供热具有一定的借鉴意义。In a city of Shandong Province,the current main heat source is a thermal power plant in the south suburb of the city,and the heat source in the city will be used as the emergency heating source.In the next heating season,a new heat source at high point of the heating system will be added to heat.Because the height difference of the two main heat sources is 58 m,in order to analyze the hydraulic condition after the new heat source is connected to the existing heating system,hydraulic calculation software used as a tool to establish a whole network calculation model.The hydraulic calculation and analysis system operation feasibility and corresponding solutions under various working conditions of two heat sources networking operation and network cutting operation were carried out.The two heat sources were determined to adopt the network cutting operation mode in the next heating period,and the complementary range of the two heat sources was defined.The analytical route has certain reference significance for similar multi-heat source network heating cases.
