摘　　要：通过对分布式变频系统与动力集中式系统在供热循环水泵的能耗、供热调节稳定性方面的对比分析,总结分布泵系统供热方面存在的优势.以某实际动力集中式传统管网为对象,对改造为设有均压管的分布式变频系统后水泵能耗进行对比分析;利用流体分析软件对分布式变频系统和传统供热系统的多种调节过程进行动态仿真模拟,并对分布式变频系统热源水泵事故工况进行动态仿真模拟,对比两系统调节稳定性以及供热安全性的差异.Based on distributed variable-frequency system with power-centralized energy consumption system in the heating circulation pump and heating regulation stability analysis, we analyzed pump systems of heat distribution advantages.By using a practical push-pull traditional network as objects, we compared with pressure equalizing tubes distributed variable-frequency transformation of system pumps energy consumption. By using fluid analysis software of distributed and conventional heating system dynamic simulation, the process of many regulators, we did the dynamic simulation about the heat pump and distributed variable-frequency system accident conditions to see the differences of the adjusting stability and heating safety in the two systems.
