Abstract

This paper documents a probabilistic risk assessment of existing and alternative power supply systems at a large telecommunications office. The analysis characterizes the increase in the reliability of power supply through the use of two alternative power configurations. Failures in the power systems supporting major telecommunications service nodes are a main contributor to significant telecommunications outages. A logical approach to improving the robustness of telecommunication facilities is to increase the depth and breadth of technologies available to restore power during power outages. Distributed energy resources such as fuel cells and gas turbines could provide additional on-site electric power sources to provide backup power, if batteries and diesel generators fail. The analysis is based on a hierarchical Bayesian approach and focuses on the failure probability associated with each of three possible facility configurations, along with assessment of the uncertainty or confidence level in the probability of failure. A risk-based characterization of final best configuration is presented

分布式能源对关键电信设施可靠性的影响

本文记录了一个大型电信办公室现有和替代供电系统的概率风险评估。分析表明，通过使用两种替代电源配置，供电可靠性得到了提高。支持主要电信服务节点的电力系统故障是造成重大电信中断的主要原因。提高电信设施稳健性的一种合乎逻辑的方法是增加可用于在停电期间恢复电力的技术的深度和广度。如果电池和柴油发电机发生故障，诸如燃料电池和燃气轮机等分布式能源可以提供额外的现场电力来源，以提供备用电源。该分析基于分层贝叶斯方法，重点关注与三种可能的设施配置相关的故障概率，以及对故障概率的不确定性或置信度的评估。提出了一种基于风险的最终最佳构型表征方法
