Definitions

  • the present invention relates to systems and methods for local power distribution device monitoring and control using a dedicated embedded web server. More specifically, the invention relates to monitoring local power distribution devices using distributed network (DNP) protocol and transmitting local power distribution device operating status information using a dedicated embedded web server.
  • DNP distributed network
  • a substation In existing systems for monitoring and controlling an electrical distribution network, a substation will monitor local power distribution devices.
  • the substation and the local power distribution devices typically communicate using DNP protocol over a low to medium speed network such as, for example, a wireless network (typically 9600 baud).
  • a drawback of existing substations is that they lack the ability to quickly and consistently update utility control centers with the local power distribution device operating status.
  • the local power distribution device operating status includes status information about equipment installed at the local power distribution device such as, for example, voltage and current measurements, power, operations counts, time record data, transformer temperature and oil level, and switch and circuit breaker status (open or closed, etc.). It is important for control centers to be updated quickly with the local power distribution device operating status because those devices may often be a great distance from a control center. Thus, it would be a great improvement in the art to enable a substation to communicate with local power distribution devices over existing low to medium speed networks using the established DNP protocol and to communicate with main control centers using a higher speed communication channel.
  • the present invention is directed to systems and methods for local power distribution device monitoring and control using a dedicated embedded web server.
  • a gateway located at the substation comprises a local power distribution connection device and a dedicated embedded web server.
  • the local power distribution connection device provides access to local power distribution devices using DNP protocol over a low to medium speed network such as, for example, a wireless network.
  • the dedicated embedded web server maps the local power distribution device operating status information onto displayable pages and transmits the local power distribution device operating status information using TCP/IP protocol to a web browser operating at a control center.
  • the dedicated embedded web server is also capable of receiving from the control center control commands issued in response to the local power distribution device operating status information.
  • the gateway relays control commands from the dedicated embedded web server to the local power distribution devices.
  • FIG. 1 is a block diagram of an illustrative substation monitoring and control system in accordance with the present invention
  • Figure 2 is a flow chart of an illustrative method for local power distribution device monitoring and control in accordance with an aspect of the invention.
  • FIG. 1 is a block diagram of an illustrative substation monitoring and control system in accordance with the present invention.
  • substation 110 contains gateway 114 which provides access to local power distribution devices 120.
  • Dedicated embedded web server 114b transmits local power distribution device operating status information over Internet 130 to web - ⁇ browser 140.
  • local power distribution connection device 114a provides gateway 114 with access to local power distribution devices 120.
  • Local power distribution connection device 114a communicates with local power distribution devices 120 over any network capable of supporting transfer of data using DNP protocol such as, for example, but not limited to, a wireless network, a twisted pair network, or a fiber optic network.
  • DNP protocol such as, for example, but not limited to, a wireless network, a twisted pair network, or a fiber optic network. Communication between local power distribution devices and a gateway device at a substation using DNP protocol is described in detail in U.S. Pat. No. 6,005,759, which is hereby incorporated by reference in its entirety.
  • Gateway 114 also contains dedicated embedded web server 114b for mapping local power distribution device operating status information onto predefined standards based markup language pages.
  • Local power distribution device status information includes information about equipment typically installed at local power distribution devices such as, for example, switches, circuit breakers, and transformers. Status information may also include information about additional equipment such as, for example, fault recorders, power meters, power quality monitors, and relays. Information about this equipment includes information such as, for example, voltage and current measurements, power, operations counts, records of time-stamped event data, switch and circuit breaker position, pressure, and wear data, and transformer oil level and temperature.
  • Dedicated embedded web server 114b maps local power distribution device operating status information onto predefined standards based markup language pages such as, for example but not limited to HTML and XML, transmits local power distribution device operating status information using TCP/IP protocol, and receives control commands in response to said local power distribution device operating status information.
  • Dedicated embedded web server 114b transmits local power distribution device operating status information over wide area network 130 using TCP/IP protocol to web browser 140.
  • Wide area network 130 may be any wide area network such as, for example, the Internet.
  • Web browser 140 may connect to wide area network 130 using any common network connection such as, for example, a standard dial up connection over a phone line.
  • Web browser 140 may be any web browser device such as, for example, a web browser running on a personal computer. Such a personal computer may be located at a utility's main control center or in a mobile control unit.
  • Control commands may consist of operation instructions for equipment installed at local power distribution devices 120 such as, for example, commands to open or close a switch, commands for transformer tap change, or commands to shut off or turn on power. Control commands are received at dedicated embedded web server 114b and are then transmitted to local power distribution devices 120 through local connection device 114a.
  • FIG. 2 is a flow chart of an illustrative method for substation monitoring and control in accordance with an aspect of the invention.
  • local power distribution connection device 114a monitors the operating status of local power distribution devices 120.
  • dedicated embedded web server 114b maps local power distribution device operating status information onto predefined standards based markup language pages.
  • dedicated embedded web server 114b transmits local power distribution device operating status information over wide area network 130 to web browser 140 using TCP/IP protocol.
  • web browser 140 receives local power distribution device operating status information.
  • web browser 140 issues a control command in response to the local power distribution device operating status information.
  • the control command is received by dedicated embedded web server 114b.
  • the control command is relayed to a local power distribution device 120 through local power distribution connection device 114a.
  • the control command is received and implemented by local power distribution device 120.
