摘要： Protection, measurement and control IEDs in a substation compute if switches they control may be operated safely, according to interlocking rules or physical principles as well as the dynamic topology of the substation. The IEDs have access to the substation electrical topology, to real-time information generated by other IEDs, and to the rules for interlocking. A standardized Substation Configuration Description (SCD) of the substation for which a Substation Automation system is intended, and a standardized description of the implemented device functions or capabilities of an individual IED are utilized. The substation topology is available from SCD file, real time information about the position of switches and line voltage/current can be obtained via an appropriate protocol, and the interlocking rules are available in script form. These features apply both to simulated and real devices, and increase system testing possibilities by supporting an efficient configuration of a simulation.

摘要： Exemplary embodiments increase reliability of communication over a non-deterministic communication channel, in electric power systems. A communication channel is monitored based on regular network traffic, by evaluating messages or data packets carrying real-time operational data as a payload. A permanent determination of a channel quality, including appropriate alarming in case the channel quality is found insufficient, is based on an evaluation, at a receiving node, of data packets continually transmitted by a sending node. These continually or repeatedly transmitted data packets can include identical payloads reflecting current states rather than state changes as operational data.

摘要： The present disclosure provides a method and system for operation of substations in which protection, control and measurement devices (e.g., Intelligent Electronic Devices (IEDs)) exchange operational data over a data network, for example, according to IEC standard 61850. During maintenance, commissioning and fault situations, when one or several IEDs are inoperable, the data that these IEDs would have produced is substituted to ensure availability of the substation. To this effect, a dedicated substitute device is permanently installed that can take the role of any IED, and that is automatically configured out of a standard configuration description (SCD) file that describes the SA system.

摘要： A communication device is provided with a power-limiting module connected to the power supply and configured to limit energy supplied to the transmitter portion such that a defined maximum data transmission rate is not exceeded. The power-limiting module comprises an energy storage device, supplying energy to the transmitter portion, and a limiter limiting recharging of the energy storage device by the power supply. The energy storage device and the limiter are selected such that a defined maximum energy is suppliable to the transmitter portion, limiting the transmitter portion to transmit data at the maximum data transmission rate. Limiting the energy supplied to the transmitter portion ensures that the communication device does not transmit over the network more than a given, limited amount of information per time unit, thus, the quantity of data transmitted by the communication device is limited.

摘要： Exemplary embodiments are directed to deterministic data transmission of real-time operational data in Highly available, Seamlessly Redundant (HSR) ring-type communication networks with at least a master node, a source node, and a destination node. Each node can include first and second communication ports connected to a respective first and second neighbouring node of the communication network, to receive a frame via the first communication port, and to forward the received frame via the second communication port. The master node sends a first and a second redundant frame or empty data packet to its first and second neighbouring node, respectively. Upon reception of the two redundant frames, the source node inserts process data into a predetermined and dedicated field of each frame. Each one of the two loaded redundant frames is instantaneously and individually forwarded to the first and the second neighbouring node of the source node, respectively. The destination node extracts the process data from the first arriving loaded redundant frame of the pair.

摘要： The present disclosure provides a secure one-step IEEE 1588 clock using either a symmetric or asymmetric protection scheme. Clocks of mission-critical or highly-available devices in industrial automation systems connected to a communication network are synchronized by sending, by a master clock, a synchronization message, e.g., a single message of the one-step-clock type according to IEEE 1588, including a time stamp, and by receiving and evaluating, by a slave clock, the synchronization message. A synchronization component or module of the master clock prepares, or composes, prior to a projected send time, a synchronization message including a time stamp of the projected send time, and secures the synchronization message in advance of the projected send time. Securing the synchronization message occurs by suitable cryptographic means allowing for authentication of the time stamp at a receiving slave clock. At the projected send time, the secured synchronization message is transmitted.
摘要翻译：本公开提供了使用对称或非对称保护方案的安全的一步IEEE 1588时钟。连接到通信网络的工业自动化系统中的任务关键或高可用设备的时钟通过主时钟发送同步消息（例如，根据IEEE 1588的单步时钟类型的单个消息）来同步，包括时间戳，并且通过从属时钟接收和评估同步消息。主时钟的同步组件或模块在投影的发送时间之前准备或组合包括投影的发送时间的时间戳的同步消息，并且在预计的发送时间之前确保同步消息。通过允许在接收从时钟处的时间戳的认证的合适的加密装置发生保护同步消息。在预计的发送时间，发送安全的同步消息。

摘要： Exemplary embodiments are directed to a network coupling device connected over a respective first and second port in a communication network with a ring topology operating with full duplex links. When sending information, the coupling device inserts two duplicate frames in the ring, one over each of its ports. The frames containing information that identifies these two frames as a pair of duplicates of the same frame. Each similar device in the ring includes a Switching Element that receives a frame from one port and forwards the frame to the other port without modification. The Switching Element discards a frame that was originally sent by that same node, discards a frame that it already forwarded in that direction, and/or discards a frame that it cannot recognize as being a member of a pair. A further similar device on the ring is able to receive the two duplicate frames and pass the earlier received frames of a pair to the application, while discarding the later, received frames based on the identification within the frames.
