摘　　要：通过理论计算的方法,应用流量偏移系数法对比分析了各种典型集中供热系统的稳定性。得出如下结论:在所有的典型集中供热系统中,无源分布式变频集中供热系统稳定性最好,传统集中供热系统的稳定性次之,有源分布式变频集中供热系统的稳定性最差。有源分布式变频集中供热系统零压差点处于管网两端稳定性较好,处于管网中间稳定性较差。Using the flow offset coefficient methods the kinds typical central heating system’s stability was studied through theoretical calculations.The following conclusion was drawn: In all the typical central heating systems,the stability of the central heating system with distributed variable speed pump which does not have source pump is the best,the traditional central heating system is better,the central heating system with distributed variable speed pump which has source pump is the last;The zero pressure drop point at the two sides of the central heating system with distributed variable speed pump which has source pump is better and at the middle is worse.

关 键 词：集中供热系统 稳定性 零压差点 分布式变频系统
