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. Processing of the collected waveform data to display any one of the eight waveform parameters (i.e., Ia, Ib, Ic, In, Va, Vb, Vc, Vx) or a combination thereof including an “all” selection in a window tiling format is provided.

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. A client sends its requests to server to read/write some device registers. The server maps each request to suitable device read/write request packets and carries out the necessary transaction with device. Then it relays the result back to the client after processing and casting the collected device data to proper format.

Abstract translation: 介绍了允许外部程序访问电源管理数据的动态数据交换（DDE）服务器。 DDE服务器在注册表项和标准化的字母数字参数名称之间提供助记符交叉引用。 该助记符接口允许用户从设备中检索数据，而不了解实际的设备寄存器项目号码。 此外，DDE服务器会自动为所有受支持的设备执行时间同步，并提供一致的波形和事件接口。 DDE服务器针对Modbus RTU或以太网协议进行了优化。 DDE服务器包括用于维护DDE通信和协议定时器以及维护活动主题和项目列表的工具包功能。 DDE服务器充当客户端请求设备数据和可以提供数据的现场设备之间的链接。 DDE服务器通过通信端口和现场设备通过DDE消息链路与客户端进行通信。 客户端将其请求发送到服务器以读/写一些设备寄存器。 服务器将每个请求映射到适当的设备读/写请求数据包，并与设备执行必要的事务。 然后，在将收集的设备数据处理并转换为适当的格式后，将结果中继到客户端。
