Abstract

Direct current (DC) power systems have been advancing renewable energies to cope with the worldwide effort in minimizing carbon footprints. However, dc systems face technical limitations that require protection from dc circuit breakers. This article deals with the techno-economic analysis of dc solid-state circuit breakers (SSCBs) by involving design, cost, and performance parameters. To clarify the current situation and identify future needs, dc SSCBs are analyzed from three aspects. First, the deciding factors and performance criteria are illustrated. Second, the driving factors, technical challenges, and applications of dc SSCBs are discussed. Finally, the techno-economic analysis of practical SSCBs is elaborated. The presented concepts are evaluated by a 4 kV/100 A dc SSCB prototype as a case study, where the cost distribution among components is discussed. The results show that practicing marketing and economic perspectives in designing dc SSCBs can help to pave the way for advancing dc power system protection and facilitating fully penetrated dc transmission and distribution networks.

直流电源系统应用中固态断路器的技术经济分析：设计、成本和性能分析

直流（DC）电力系统一直在推动可再生能源的发展，以应对全球范围内尽量减少碳足迹的努力。然而，直流系统面临技术限制，需要直流断路器提供保护。本文通过设计、成本和性能参数对直流固态断路器（SSCB）进行技术经济分析。为了明确现状和未来需求，本文从三个方面对直流固态断路器进行了分析。首先，说明了决定因素和性能标准。其次，讨论了直流 SSCB 的驱动因素、技术挑战和应用。最后，阐述了实用 SSCB 的技术经济分析。以一个 4 kV/100 A 直流 SSCB 原型作为案例研究，对提出的概念进行了评估，并讨论了各组件之间的成本分配。结果表明，在设计直流 SSCB 时从市场和经济角度出发，有助于为推进直流电力系统保护和促进直流输配电网络的全面普及铺平道路。
