摘要： Systems, devices, and methods include protection functions in an electrical power system. A processing subsystem may include a processor. A memory subsystem may comprise a first memory section and a second memory section. A memory management subsystem may, in a first operational mode, enable memory access between the processor and the first memory section and the second memory section and, in a second operational mode, enable memory access between the processor and only the first memory section.

摘要： The present disclosure relates to systems and methods for calculating noise distributions in an electric power system. In one embodiment, a system to calculate a noise distribution in an electric power system may comprise a measurement subsystem to obtain a plurality of raw measurements of a parameter in the electric power system. A noise distribution determination subsystem may be configured to generate a plurality of scaled raw measurements from the plurality of raw measurements, generate a power spectrum density from the plurality of scaled raw measurements, generate a cumulative distribution from the power spectrum density, and determine a noise distribution from the power spectrum density. A protective action subsystem may monitor the parameter in the electric power system to identify a signal of interest by utilizing, at least in part, the noise distribution and generating a control action in response to the signal.

摘要： Systems and methods described herein monitor real-time digital data for degradation. A merging unit may measure electrical parameters in an electric power system using a sensor component and may generate a stream of digital data representing measured electrical parameters. The merging unit may transmit the stream of digital data representing measured electrical parameters and receive a plurality of data frames using an interface. A digital data degradation detection subsystem may analyze a plurality of digital metrics associated with the plurality of data frames and make a determination of whether a subset of the plurality of data frames satisfies the plurality of digital metrics, and the subset of the plurality of data frames fails at least one of the plurality of digital metrics. The merging unit may implement a response when the subset of the plurality of data frames fails at least one of the plurality of digital metrics.

摘要： Systems and methods are described herein to accommodate different settings associated with an inverter-based electric power generator and an inverter-based electric power generator for electric power generation within an electric power delivery system. The electric power delivery system may provide electric power generated by a bulk electric system to the loads via distributed substations using a first operating frequency. Moreover, the distributed substations may include inverter-based electric power generators to supply the electric power demand of downstream loads in an islanded configuration. That said, the inverter-based electric power generators may supply the electric power using a second frequency that is higher than the first frequency. Protective systems, positioned downstream from the distributed substations, may use different settings associated with the bulk electric system or the inverter-based electric power generators based on detecting the frequency of the supplied electric power.

摘要： An intelligent electronic device (IED) of an electric power delivery system includes processing circuitry a memory that includes instructions. The instructions, when executed by the processing circuitry, are configured to cause the processing circuitry to receive first data via parallel redundancy protocol (PRP), generate a first integrity check value using a media access control security (MACsec) integrity check function based on the first data, receive second data via PRP, generate a second integrity check value using the MACsec integrity function based on the second data, compare the first integrity check value and the second integrity check value with one another, and output a notification in response to determining that the first integrity check value and the second integrity check value do not match one another.

摘要： The present disclosure relates to token-based authentication that uses authentication data including a personal identification number (PIN). For example, an issuer may obtain privilege information including the PIN. The issuer may combine the privilege information with authentication information. The issuer may determine an issuer hash value based on the combined privilege information and authentication information. The issuer may determine an encrypted hash value based on the issuer hash value and a private key of the issuer. The issuer may combine the privilege information with the encrypted hash value as a token. The issuer may then issue the token. The receiver can restrict allowed operations appropriately based on success decrypting the encrypted hash.

摘要： The present disclosure pertains to devices, systems, and methods for monitoring a direct current (DC) system. In one specific embodiment, a system may include a centralized protection and control (CPC) system. The CPC system may include a DC interface configured to be in electrical communication with a first DC system and a communication subsystem configured to receive a first measurement, from a remote device, of at least one electrical parameter of the first DC system. The CPC system may also include a DC monitor subsystem to generate a second measurement of at least one electrical parameter of the first DC system based on the electrical communication between the DC interface and the first DC system and generate a comparison of the first measurement and the second measurement. An action subsystem may generate an action based on the comparison between the first measurement and the second measurement.
