Abstract: The present disclosure provides systems and methods for extending a deterministic network over a wide geographical area. According to one embodiment, an IED may transmit data frames using a deterministic frame-based communication protocol, such as EtherCAT, via a local deterministic fieldbus. A first transceiver may encapsulate the data frames for transmission over a multiplexing synchronized optical network, such as a SONET network. A second transceiver may de-encapsulate the encapsulated data frames and transmit them via a remote deterministic fieldbus, such that communication between the local and remote deterministic fieldbuses is deterministic. Accordingly, an IED may communicate with a high level of determinism and/or in real-time with various components in a power delivery system across a wide geographical area including multiple deterministic fieldbuses.

Abstract: La presente se describen diversos sistemas y métodos que pueden mejorar la transmisión de datos sobre canales de comunicación de ancho de banda bajo en un sistema de suministro de energía eléctrica. Los dispositivos se comunican a través de un canal de comunicación de ancho de banda bajo pueden incrementar varias soluciones, de acuerdo con diversas modalidades que aquí se describen, para reducir los datos transmitidos a través del canal de comunicación de ancho de banda bajo y priorizar la transmisión de información sensible al tiempo y/o más importante con respecto a otros datos. Diversas modalidades que aquí se describen pueden inspeccionar paquetes que se van a transmitir a través de un canal de comunicación de ancho de banda bajo con el fin de identificar datos de alta prioridad. Los datos de alta prioridad puede ser información sensible al tiempo y en consecuencia la transmisión de estos datos se puede priorizar sobre otros datos con el fin de reducir la latencia de transmisión de los datos de prioridad superior.

Abstract: 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.

Abstract: La presente descripción proporciona sistemas y métodos para extender una red determinística sobre un área geográfica amplia. De acuerdo con una mdalidad, un IED puede transmitir los cuadros de datos utilizando un protocolo de comunicación a base de un cuadro determinístico, tal como EtherCAT, por medio de un bus de campo determinístico local. Un primer transceptor puede encapsular los cuadros de los datos para la transmisión sobre una red óptica sincronizada de multiplexión, tal como una red SONET. Un segundo transceptor puede desencapsular los cuadros de datos encapsulados y transmitirlos por medio de un bus de campo determinístico remoto, de tal modo que la comunicación entre los buses de campo determinísticos local y remoto sea determinística. En consecuencia, un IED puede comunicarse con un alto nivel de determinismo y/o en tiempo real con varios componentes en un sistema de suministro de energía a través de un área geográfica amplia incluyendo buses de campo determinísticos múltiples.
