20110069709 | INTELLIGENT ELECTRONIC DEVICE WITH SEGREGATED REAL-TIME ETHERNET - A system and method for optimizing the handling of data on a priority basis within an intelligent electronic device is disclosed. A FIFO receives messages and the messages are each associated with a subscription identifier. The messages are then routed to and stored in buffers, each associated with a subscription identifier. | 03-24-2011 |
20140269736 | Transmission of Data Over a Low-Bandwidth Communication Channel - Disclosed herein are various systems and methods that may improve the transmission of data over low-bandwidth communication channels in an electric power delivery system. Devices communicating across a low-bandwidth communication channel may implement several approaches, according to various embodiments disclosed herein, to reduce the data transmitted across the low-bandwidth communication channel and to prioritize the transmission of time-sensitive and/or more important information with respect to other data. Various embodiments disclosed herein may inspect packets to be transmitted across a low-bandwidth communication channel in order to identify high priority data. High priority data may be time-sensitive information, and accordingly, transmission of such data may be prioritized over other data in order to reduce transmission latency of the higher priority data. | 09-18-2014 |
20140280672 | Systems and Methods for Managing Communication Between Devices in an Electrical Power System - Systems and methods for managing communication between devices in an electric power generation and delivery system are disclosed. In certain embodiments, a method for managing communication between devices may include receiving a message including an identifier via a communications interface. In certain embodiments, the identifier may identify a particular publishing device. A determination may be made whether the message is a most recently received message associated with the identifier. If the message is the most recently received message, the message may be stored message in a message buffer associated with the identifier, and transmitted from a device using a suitable queuing methodology. | 09-18-2014 |
20140280673 | SYSTEMS AND METHODS FOR COMMUNICATING DATA STATE CHANGE INFORMATION BETWEEN DEVICES IN AN ELECTRICAL POWER SYSTEM - Systems and methods are presented for managing communication between devices in an electric power generation and delivery system. In certain embodiments, a method for managing communication messages performed by a network device included in an electric power generation and delivery system may include receiving a message including an identifier and data state information via a communications interface. A determination may be made that that the message represents a data state change associated with the identifier. The message may be stored in a message buffer associated with the identifier. Finally, the stored message may be transmitted from the message buffer to an intelligent electronic device. | 09-18-2014 |
20140280712 | Exchange of Messages Between Devices in an Electrical Power System - Systems and methods are presented for exchanging messages between devices in an electrical power generation and delivery system. In certain embodiments, a method for exchanging messages between devices may include transmitting messages included in a message stream that includes multiple redundant copies of the messages. An indication may be received that at least one message of the message stream was received by an intended receiving device. Transmission of further redundant copies of the message included in the message stream may be determined based on receipt of the indication. | 09-18-2014 |
20140280713 | Proxy Communication Between Devices in an Electrical Power System - Systems and methods for exchanging messages between network devices and intelligent electronic devices of the electric power generation and delivery system are disclosed herein. In certain embodiments, a method performed by a network device for managing the exchange of messages between a first intelligent electronic device (IED) and a second IED included in an electrical power generation and delivery system may include receiving one or more messages configured according to a first communication protocol from the first IED. Based on information regarding one or more communication capabilities of the second IED, a second communication protocol may be determined. The message be reconfigured according to the second communication protocol to generate at least one reconfigured message. The reconfigured message may then be transmitted to the second IED. | 09-18-2014 |
20140280714 | Mixed-Mode Communication Between Devices in an Electrical Power System - Systems and methods are presented for facilitating mixed-mode communication between stations in an electric power generation and delivery system. In certain embodiments, a method for facilitating mixed-mode communication between a first device configured to communicate according to a first communication protocol and a second device configured to communicate according to a second communication protocol is presented The method may include installing a network device in a communication channel between the first device and the second device. A communications interface of the network device may be configured to receive messages from the first device and the second device. A message reconfiguration system of the network device may be configured to reconfigure messages received by the network device from the first device to reconfigured messages for transmission to the second device. | 09-18-2014 |
20140282021 | Visualization of Communication Between Devices in an Electric Power System - Systems and methods are presented for visualizing various devices in an electric power generation and delivery system. In certain embodiments, a method for visualizing communication may include receiving configuration information from an electric power generation and delivery system. Based on the configuration information, a plurality of devices included in the electric power generation and delivery system may be identified. Further, a plurality of communication pathways may be identified.
