Abstract: Systems and methods for network failover in digital substations are provided. One method includes receiving, by an intelligent electronic device (IED) from a process interface unit (PIU), in parallel a pre-configured data stream via a point-to point connection and one or more other data streams via an Ethernet network. The method further includes determining that at least one of the following failure conditions is satisfied: a frame in the pre-configured data stream is lost or delayed, quality of the data in the frame in the data stream is below a first threshold, period of the time associated with the data in the frame in the data stream is below a second threshold, or a health indicator associated with the PIU is below a third threshold. The method further allows identifying at least one redundant frame in the one or more other data streams. If the quality of data in redundant frame is satisfactory, the method proceeds to use the redundant frame for further processing.

Abstract: 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.

Abstract: Provided is a system for synchronizing time sources within a protection zone of a digital power substation. The system includes a global time source, a processing communication network, an electronic, and a process unit. The process unit includes a time source configured to receive and process data packets, which include a first time signal and first time quality from the global time source and the second time signal and second time quality from the electronic device. A time source of the process unit synchronizes with a protection zone master clock within the electronic device where the first time signal is unavailable or the first time quality of the global time source is degraded below a predetermined threshold. The embodiments also include a method for synchronizing time sources within a protection zone of a digital power substation.

Abstract: One embodiment describes a non-transitory tangible computer-readable medium storing a plurality of instructions executable by a processor of an electronic device in a wide area monitoring system. The instructions include instructions to receive a synchro-command from the wide area monitoring system via a network interface, in which the synchro-command is time synchronized with a global clock by a time stamp encoded on the synchro-command; accept or reject the synchro-command with an input handler based at least in part on a sender ID and a receiver ID encoded on the synchro-command; schedule execution of a control command encoded on the synchro-command with a synchro-command manager based at least in part on a scheduler time encoded on the synchro-command; and execute the control command encoded on the synchro-command with the processor based at least in part on an application ID encoded on the synchro-command.

Abstract: Systems, methods, and apparatus for providing a synchronized phasor in power system based on voltage and current measurements, sampling of the voltage and current measurements and convolving the samples with a function.
