This disclosure relates to systems and methods for configuration-less process bus. In one embodiment, the system includes at least one process interface unit (PIU). The PIU includes at least one pre-configured communication port defined by one of a factory setting or a product code order. The at least one PIU is operable to transmit and receive a data stream. The data stream includes at least one dataset. The dataset includes at least one field for sampled values measured at least at one source. The source includes one of a current transformer or a voltage transformer. The dataset can further include a timestamp and a unique identifier associated with the source. The system can include at least one intelligent electronic device (IED) communicatively coupled to the PIU. The IED can be operable to receive the data stream from the PIU and transform the sampled values based on user-defined transformation factors.

Systems and methods for configuration-less process bus with architectural redundancy in digital substations

A control apparatus (10) comprises an apparatus (12) for ascertaining at least one primary data path (51) between a first (41) and a second (42) data terminal device, which are connected to a data network (60), an apparatus (14) for selecting one of the ascertained primary data paths (51) and an apparatus (16) for ascertaining at least one alternative data path (52i) between the first (41) and the second (42) data terminal device, which alternative data path has no common transmission links with the selected primary data path (51). Furthermore, the invention provides a corresponding network node (20i) and a corresponding method (100).

Control apparatus, network node and method for interchanging data via a data network

An anchor node receives a packet, duplicates the packet to form two copies, flags each of two data units, each comprising one of the copies, with a duplication flag indicating the corresponding data unit comprises a copy. The anchor node sends one of the two data units through protocol layers towards transmission to a UE, and sends another of the two data units over a network interface and towards one or more duplicating nodes. A duplicating node receives in the data unit a copy of the packet. The duplicating node forwards the data unit with the packet to a first of multiple protocol layers toward transmission via an air interface toward the UE. The duplicating node discards, in the first protocol layer or in a layer lower than the first, the packet in response to receiving an ACK that a copy of the packet was successfully received by the UE.

Control device, network node and method for the exchange of data over a network

Aspects of the subject disclosure may include, providing, by a power supply of a communication device, energy to a transmitter of the communication device, wherein the power supply directly obtains the energy from a transmission medium via a capacitive divider and a DC converter, and wherein the communication device includes an insulator that electrically insulates the transmission medium from a utility structure supporting the communication device; generating, by the transmitter of the communication device, a signal; and inducing according to the signal, by a coupler of the communication device, an electromagnetic wave that propagates along the transmission medium without requiring an electrical return path. Other embodiments are disclosed.

Method and apparatus for providing power to a waveguide system

The invention relates to a network interface for redundant coupling of a substation communication network and a packet-switched WAN of a power network. The interface device comprises: a first redundancy module comprising: two LAN ports connectable with the Substation communication network, and a first interface port; a second redundancy module comprising: two WAN ports connectable with the WAN, and a second interface port; and a first interworking module connecting the first with the second redundancy module via the first and the second interface port, and adapted to forward protection data between the first and the second redundancy module.

Network interface for transmitting protection data of a power network

The present invention is concerned with a use of the Parallel Redundancy Protocol PRP (IEC 62439-3) for traffic duplication and redundant transport of the duplicated traffic in a single packet-switched wide-area communication network including a plurality of nodes (1-5) interconnected via inter-node links (a-g) in a meshed topology. It involves the step of identifying, between a send (1) and receive node (3), two distinct communication paths (A,B) with no link or node in common except for the send and receive node, as well as the step of configuring the send (1) and receive nodes (3) to operate according to the Parallel Redundancy Protocol PRP. At any time during regular operation, and for any critical message to be transmitted from the send (1) to the receive node (3), two redundant packets are then generated, and each of the redundant packets is being sent via one of the two communication paths, resulting in an increased availability of the communication network without incurring the cost of full network duplication.

Parallel Redundancy Protocol, PRP, packet duplication over VLANs based on Spanning Tree instances.

The present invention is concerned with the field of power line communication PLC, in particular with a device for coupling a communication signal to a power line. According to the invention, a capacitive Medium Voltage MV Power Line Communication PLC coupler 1 is provided, i.e. for capacitive coupling of communication signals to Medium voltage MV power conductors 4, with a signal connector 2, e.g. a coaxial jack, for exchanging communication signals with a transceiver, an MV connector 3 to be connected to an MV power conductor 4, and a coupling capacitor 5 solidly embedded in a volume of insulating material 15 electrically connecting the two connectors 2, 3. The MV PLC coupler 1 has an MV end 6, i.e. a terminal including the MV connector 3, that is adapted or shaped to be mounted, e.g. removably attached or in a form-fitting manner providing mechanical adherence and electrical insulation, to an MV bushing 7, i.e. an interface bushing, of a compact MV switchgear enclosure such as a cubicle.
