Abstract :
Houston Lighting & Power funded Texas A&M to develop an expert system based automatic disturbance analysis system that would satisfy the following requirements: PC-based system for substation application; direct interface to the existing digital fault recorder (DFR) system; graphical user interface (GUI) for viewing of results; database management for storing results; and a modem interface to the protection engineer. The system was developed and extensively tested using Electromagnetic Transient Program (EMTP) simulations and actual disturbance records captured by DFRs at various substations. Since then, the system has been connected to a substation DFR for online monitoring of disturbances. This article points out some design and implementation issues and highlights performance validation and operating experience related to the expert system.<>
