In this paper, the authors discuss the development of a distribution automation applications software package for assessing system reconfiguration opportunities and volt/var control on automated radial distribution feeders. The package, called SYSRAP (System Reconfiguration Analysis Program) was developed by the Oak Ridge National Laboratory as part of the Athens Automation and Control Experiment (AACE). The AACE is a large scale distribution automation research project being conducted on the Athens Utilities Board (AUB) in Athens, Tennessee. SYSRAP is unique because it combines power flow and short circuit analyses with data base management and is especially well suited for answering system operator questions with respect to switch orders, capacitor bank dispatch and regulator tap adjustments. The program runs on a personal computer, executes power flow and short-circuit analyses for detailed feeder models in tens of seconds, uses highly detailed feeder models including voltage sensitive loads, and is adept at reorganizing the data base to reflect switching operations and changes in the status of volt/var control equipment. Experimental observations on the AUB system have shown that voltage insensitive load models (constant power sinks) are inadequate to accurately simulate system response to system reconfiguration and volt/var control which affect feeder voltage profile.
