Abstract
Abstract Distributed feeder automation (FA) needs to automatically recognize the changes in the feeder topology in real-time and has to configure the application topology of the corresponding distributed functions. This paper analyzes the application topology’s requirements when implementing distributed FA for the feeder equipped with a smart terminal unit (STU) and a fault passage indicator (FPI). Based on IEC 61850, the functional logic node and topology configuration of intelligent electronic devices (IEDs) are studied. The application topology identification and data flow dynamic binding methods for fault location, fault isolation, and power supply restoration are proposed. A case study verifies the effectiveness of the proposed method.
