Abstract

: A feeder automation (FA) system is usually used by electricity utilities to improve power supply reliability. The FA system was realized by the coordinated control of feeder terminal units (FTUs) in the electrical power distribution network. Existing FA testing technologies can only test basic functions of FTUs, while the coordinated control function among several FTUs during the self-healing process cannot be tested and evaluated. In this paper, a novel cloud-based digital-physical testing method is proposed and discussed for coordinated control capacity test of the FTUs in the distribution network. The coordinated control principle of the FTUs in the local-reclosing FA system is introduced ﬁrstly and then, the scheme of the proposed cloud-based digital-physical FA testing method is proposed and discussed. The theoretical action sequences of the FTUs consisting of the FTU under test and the FTUs installed in the same feeder are analyzed and illustrated. The theoretical action sequences are compared with the test results obtained by the realized cloud-based simulation platform and the digital-physical hybrid communication interaction. The coordinated control capacity of the FTUs can be evaluated by the comparative result. Experimental veriﬁcation shows that the FA function can be tested eﬃciently and accurately based on our proposed method in the power distribution system inspection.

基于云的高效配电网馈线自动化系统数字物理测试方法

:电力公司通常使用馈线自动化系统（FA）来提高供电可靠性。馈线自动化系统是通过协调控制配电网络中的馈线终端单元（FTU）来实现的。现有的 FA 测试技术只能测试 FTU 的基本功能，而无法测试和评估自愈过程中多个 FTU 之间的协调控制功能。本文针对配电网中 FTU 的协调控制能力测试，提出并讨论了一种基于云的新型数字物理测试方法。首先介绍了本地重合闸 FA 系统中 FTU 的协调控制原理，然后提出并讨论了基于云的数字物理 FA 测试方法的方案。分析并说明了由被测 FTU 和安装在同一馈线上的 FTU 组成的 FTU 的理论动作序列。将理论动作序列与已实现的云仿真平台和数物混合通信交互所获得的测试结果进行了比较。通过比较结果可以评估 FTU 的协调控制能力。实验验证表明，在配电系统检测中，基于我们提出的方法，可以对 FA 功能进行高效、准确的测试。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
