摘要

Advances in communications and computer technologies have increased the electric utilities' ability to monitor and control power systems. Whenever there is a violation of the operation limits or a status change, an alarm is generated by Energy Manager System (EMS). On the other hand, relay operations can be recorded by Sequence-of-Events Recorders (SERs) with an accuracy level within milliseconds. This resulted in a significant increase in the amount of information collected on- or off-line. Accurately and efficiently analyzing the increasing amount of information is a challenging and difficult task.;In this dissertation, three intelligent systems are developed for on- and off-line analysis of EMS and SER information. Chapter 2 of this dissertation describes the development of a RElay Testing EXpert system (RETEX) for off-line relay performance evaluation. Rule bases are constructed for determining expected operations of the relay, evaluate relay operations and writing reports. RETEX incorporates the evaluation of distance relays, traveling wave relays, differential relays, out-of-step relays and relay sets. RETEX has been tested using actual relay testing data from Bonneville Power Administration (BPA).;Chapter 3 describes the development of a logic-based on-line fault diagnosis system called Intelligent Alarm Analyzer (IAA). IAA identifies necessary SER information that will help pinpoint the fault location(s) and malfunctioning device(s). Logic-based fault and malfunction analysis algorithms are developed using SER information and EMS status data. These algorithms are implemented as member functions in an object-oriented software so that an inference engine or search method normally needed by expert systems is not necessary. Tests of actual data from ENEL show that the IAA is very efficient and promising for the on-line operational environment.;Chapter 4 describes the development of a model-based Advanced Alarm Processor (AAP). In this research a cause-effect model for processing communication alarms is developed. A logic-based method to integrate the communication module, transformer module, status processing module and power flow relation module is also developed. Logic functions for alarm processing and message generation are derived. The AAP has been implemented using an object-oriented approach. Tests of actual data from Puget Sound Power & Light Co. have demonstrated that AAP is highly efficient.
