    摘要: In one aspect, a fuel cell power system is provided. The fuel cell power system includes a ring bus, a plurality of bidirectional uninterruptible power supplies (UPSs), a plurality of direct current (DC) fuel cell modules, and a plurality of bidirectional direct current to alternating current (DC-AC) power converters. Each of the plurality of UPSs is electrically coupled to at least one battery, an AC utility feed, a load, and via a choke, the ring bus. Each of the plurality of DC fuel cell modules includes one or more fuel cells coupled to a hydrogen storage. Each of the plurality of bidirectional DC-AC power converters is electrically coupled to a corresponding one of the plurality of DC fuel cell modules and a corresponding one of the plurality of bidirectional UPSs at the AC utility feed.

    摘要: An intelligent electronic device (IED) having a programmable display is provided. The present disclosure provides for defining screens of a display on a revenue based energy meter. The method utilizes Modbus registers and defines a programming technique wherein a user can custom make any desired screen for every application based on what a user needs. The programming utilizes Modbus registers maps to allow for the customizable screens. Moreover, the display interface allows for customized labeling to provide notice and information to users as to measured parameters other than electricity that the meter might be accumulating such as steam, water, gas or other type of commodity.

    摘要: A meter is provided having a communication interface for receiving and interfacing with a communication device for transmitting measurement and other data to a central computer station via the communication device. The meter includes a measurement module for obtaining measurement data and a processor having a memory for storing application software for communicating the measurement and other data to the communication interface. The data are then provided to the communication device via the communication interface. The communication device is preferably a plug-and-play PCMCIA-type card or other type of memory card having a processor and a connection port for connecting to a port adaptor of the communication interface for receiving the data via the connection port-port adaptor connection. The communication device further includes communication circuitry for communicating the received data to the central computer station via one or more communications networks according to a communications protocol pre-programmed within the processor.
