多热源环状热网可靠性评估方法研究
Reliability assessment method of multi-heat source ring-shaped heat-supply networks
摘要：
提出了一种基于故障影响分析的多热源环状热网可靠性评估方法，该方法将元件故障概率与热网故障工况水力分析相结合，采用可修复系统模型来评估热网的可靠性。给出了一系列热用户供热可靠性指标和热网系统可靠性指标。对一实际热网进行了可靠性评估和分析，找出了热网的薄弱环节，提高了其可靠性。

Abstract：
Presents a reliability assessment method based on a failure effect analysis, in which component failure probability is combined with hydraulic analysis under failure conditions and the reliability of heat-supply networks is evaluated with a repairable system model. Sets up a series of reliability indexes for heat users and heat-supply network systems. Assesses and analyses the reliability of an actual heat-supply network, finds the weak part, and thus improves the reliability.
