Component Monitoring and Dynamic Loading Visualization from Real Time Power Flow Model Data

Abstract: The technology of intelligent electronic devices in power systems has exploded and with it the available real time data. The data are typically used to extract a real time model of the system via traditional state estimation methods. The traditional approach estimates only the system voltages and uses a small part of the available information. This paper presents a new approach for better utilization of the available information. Specifically, we propose the use of existing data for estimating detailed operational models of major power equipment. For example, the detailed models can be in the form of electro-thermal models which then will allow the monitoring of device temperatures, dynamic loading, etc. In general, the real time model can be as simple or as complex depending on the type and quality o
