Abstract:

A power management and control system having a dynamic data exchange (DDE) server simulator for simulating supervisory management and control of electrical distribution systems is presented. The DDE server simulator is an alternative DDE server which simulates device values rather than acquiring data from real devices. The DDE server simulator generates and calculates device data from user generated electrical property profiles and updates DDE compliant clients. The DDE server simulator accepts the actual topics and item names and power profiles are user configurable with an option to apply white noise to the data, which provides true-to-life values to the user. These simulated measured values are used to calculate derived parameters and pre-set arrays provide wave form data in the proper format. Device events and trips can be interjected by the user and properly interpreted by the simulator. The data is passed to the clients via DDE.

Abstract:

A utility for rapid development of three dimensional representations of electrical distribution switchgear is provided. These switchgear elevations have logical connections to the switchgear devices. An elevation can be modified to any dimensions with an infinite number of combinations and arrangements of meters and protection devices to quickly and accurately represent a customer's switchgear. Also, an event logger utility is provided for viewing, organizing and analyzing unusual behavior in a power system. The event logger utility passes a received message as an un-acknowledgeable or acknowledgeable alarm or as an event based upon the contents of a initialization file. A utility for the waveform capture is provided for viewing and analysis of waveforms (e. g. , Fourier, frequency and/or harmonic analysis) captured by sophisticated metering devices. Waveforms from a device may be super-imposed for analysis.
