Quality Assurance Solutions for Monitoring and Control Software Systems of Electrical Substations

摘要

General aspects regarding monitoring and control systems of electrical substations are discussed. Solutions are proposed to ensure software quality including methods for preventing fault injection and techniques meant to eliminate and isolate faults. Using a monitoring system developed in Romania as case study, we proposed modeling this system using SCL language and Bayesian networks in order to estimate its reliability. A software simulator for IEDs was created for this system and was used during specific tests.
