摘要: 为了解供热系统可靠性评价的研究进展并探明其发展前景,应用Google Scholar系统调研该领域的相关文献。梳理供热系统故障工况功能特征、故障状态判定准则、可靠性评价指标等方面的研究成果;将多样化发展的可靠性评价方法归纳为基于故障工况结构特征、水力特征和热力特征3类方法,总结其要点与不足,并提出供热系统可靠性评价的研究重点。研究表明:基于故障工况热力特征的供热系统可靠性评价方法是今后的研究重点;综合考虑故障工况热用户连通性、水力特征、供热管网和供暖建筑物的热惰性的模型的精度和计算复杂度是亟待解决的问题;需要开展供热系统多重和次生故障的研究。

Abstract: To have a general overview of progress in researches on district heating reliability evaluation and predict the trends in the researches, a systematic and thorough literature review was carried out through Google Scholar. From the perspective of functional characteristics under failure condition, failure state judgment criterion and evaluation index, the advances in researches on district heating reliability evaluation were summarized. The research contents and limitations of 3 evaluation methods, considering structural characteristics, hydraulic characteristics and thermodynamic characteristics under failure condition respectively, were furthermore discussed and analyzed. Finally, the trends in the researches on district heating reliability evaluation were presented. Research results show that the evaluation method considering thermodynamic characteristics under failure condition will be the focal point of the research in the days to come, that improving the accuracy of the model taking into account integrating connectivity of heat users, hydraulic characteristics and thermal inertia of heating network and buildings and the reducing the computational complexity are the problems to be solved, and that the effects of both the multiple failures and the secondary failures on the district heating system need to be studied.

Key words: district heating system, reliability, evaluation index, failure condition, functional characteristics
