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.
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.
