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 dynamic data exchange (DDE) server which allows external programs to access power management data is presented. The DDE server provides a mnemonic cross reference between register items and standardized, alphanumeric parameter names. This mnemonic interface allows the user to retrieve data from a device without knowledge of the actual device register item number. Also, the DDE server automatically performs time synchronizing for all supported devices and provides a consistent waveform and event interface. The DDE server is optimized for either the Modbus RTU or Ethernet protocol. The DDE server includes toolkit functions which are used to maintain DDE communication and protocol timers and to maintain active topic and item lists. The DDE server acts as a link between a client requesting device data and a field device which can provide the data. The DDE server communicates to the field device through communication ports and to the client via DDE message link.
