分布式供暖输配系统在二次网改造中的应用
Application of distributed heating transmission and distribution systems in secondary network reconstruction
摘要：
分布式供暖输配系统因其节电、调节灵活等特点，在一次网中应用较成熟，但在二次网中推广较少。以某严寒地区供暖项目为例，对3种供暖方案的比较表明，利用分布式供暖输配系统改造换热站二次网的供暖效果较好，节电量达到了17.7%，为解决二次网平衡提供了新思路。

Abstract：
Due to its power saving and flexible adjustment characteristics, the distributed heating transmission and distribution system is more mature in the primary network, and less popular in the secondary network. Taking a heating project in a severe cold zone as an example, by comparing three types of heating schemes, concludes that the use of distributed heating transmission and distribution system to transform the secondary network of the heat exchange station has a better heating effect, and the power saving reaches 17.7%, which provides a new idea for solving the balance problem of secondary network.
