馈线自动化终端注入测试法及其应用

Feeder Automation Terminal Injection Test Method and Its Application

当前国内许多城市都开展了配电自动化试点工作,馈线自动化作为提高供电可靠性的重要手段日益受到供电公司的重视。文中提出一种终端注入测试法,通过在配电终端二次端子上注入故障特性数据,用于现场测试配电自动化系统的馈线自动化功能的有效性。文章系统地阐述了测试方法的基本原理、测试系统的组成与功能,并以天津生态城馈线自动化现场测试为背景,详细介绍了馈线自动化终端注入测试法的测试步骤,列出了现场影响馈线自动化正常处理故障的主要问题及其解决方案。

As an important means to improve the power supply stability,the feeder automation has drawn increasingly wide attention from power supply companies. This paper presents a terminal injection test method,which is used to test effectiveness of the feeder automation function of the distri-bution automation system by injecting fault characteristic data into the secondary terminals of the distribution terminal. The paper systematically introduces the basic principles of the test method,the composition and function of the test system. Based on the field test of the feeder automation in Tianjin Eco-city,the paper details the test procedure of the feeder automation terminal injection test method,lists the main problems existing in the normal processing of failures in the feeder automation on the job site. The results have reference value for the practical application of distribution automation.
