摘要
基于遥信处理的配网自动化(DA)系统能高效及时地实现故障定位、隔离以及恢复供电功能。这种处理方法与以往基于模拟量处理的DA系统的实现方法不同,后者需要使用大量准确的模拟量信号来实现故障的定位,算法实现过程相对较复杂,而前者只需借助遥信信号即可实现故障的准确定位。文章从拓扑分析及深度优先搜索(DFS)的角度,介绍了基于遥信的DA系统的实现过程。实验结果表明,基于遥信处理的DA系统能准确定位出各种故障,并能适应多点同时故障。
The DA （Distribution Automation） system based on digital signals can efficiently achieve goals of fault location, isolation and restoration of power supply. The method is different from the one used in the analog signals based DA system. The latter requires a large number of accurate analog signals to locate thults and has a relatively complex algorithm implementation, but the former can accurately locate faults just depending on the digital signals. From two aspects of topology analysis and depth-first-search （DFS）, this paper introduces the implementation process of digital signals based DA systems. Experimental results show that the system can accurately locate various thults and handle a few faults appeared concurrently in different positions.
