Abstract

Underground compressed air energy storage (UCAES) gets the rapid development over these years. The string as a channel for air injection and extraction is a critical component of UCAES. The erosion-corrosion degradation is an important failure causation of UCAES string. This paper builds a probabilistic approach for dynamic failure assessment of UCAES string subjected to erosion-corrosion degradation. A dynamic Bayesian network (DBN) model is established to present the failure scenario of string, which considers the synergistic of erosion and corrosion. Thus, the real-time failure probabilities of string due to the coupling of erosion and corrosion are estimated. Subsequently, a DBN model incorporating the mathematical synergistic relationship of erosion and corrosion is developed to estimate the degradation rate and failure time of string. The approach is illustrated by a case study. It can be found that it can be an useful tool to guide safety management of UCAES string.

地下压缩空气储能管柱侵蚀-腐蚀退化动态安全评价

地下压缩空气储能（UCAES）近年来得到了快速发展。管柱作为空气注入和抽提通道是UCAES的关键组成部分。冲蚀退化是导致UCAES管柱失效的重要原因。本文建立了UCAES管柱受侵蚀-腐蚀退化动态失效评估的概率方法。建立了考虑冲蚀和腐蚀协同作用的管柱失效动态贝叶斯网络（DBN）模型。因此，可以实时估计管柱因侵蚀和腐蚀耦合而失效的概率。随后，建立了结合侵蚀和腐蚀数学协同关系的DBN模型，用于估算管柱的降解速率和失效时间。通过一个案例研究说明了这种方法。可以作为指导UCAES管柱安全管理的有效工具。

期刊介绍： Elsevier publishes Reliability Engineering & System Safety in association with the European Safety and Reliability Association and the Safety Engineering and Risk Analysis Division. The international journal is devoted to developing and applying methods to enhance the safety and reliability of complex technological systems, like nuclear power plants, chemical plants, hazardous waste facilities, space systems, offshore and maritime systems, transportation systems, constructed infrastructure, and manufacturing plants. The journal normally publishes only articles that involve the analysis of substantive problems related to the reliability of complex systems or present techniques and/or theoretical results that have a discernable relationship to the solution of such problems. An important aim is to balance academic material and practical applications.
