供热管网分阶段设计的可靠性研究方法
Reliability research on design of district heating network by stages
摘要：
在供热管网传统设计流程的基础上，将其分解为拓扑结构设计和管径与循环水泵设计，并相应地进行结构备用和输送能力备用的可靠性研究。基于可靠性分析的需求，增加阀门布局设计阶段。根据各阶段设计条件与内容，提出相应的故障判定原则、可靠性评价指标和分析方法。

Abstract：
Based on the traditional design procedure, divides the design of heating network into two stages, namely, one for topology and the other for diameters and circulating pumps. The corresponding reliability researches are performed for both the structure reservation and transportation capacity reservation. Besides, inserts the design of valve distribution between the above stages to cater for the need of reliability analysis. According to different conditions and design contents during each stage, puts forwards the failure judgment principles, reliability evaluating indicators and analysis methods for each stage.
