Abstract: The present disclosure pertains to configuration of devices using distributed network protocols. In one embodiment, a client may poll a server device and receive a first set of data using a first communication protocol. The client may analyze the first set of data to determine a number and a type of each of a plurality of data points comprised in the first set of data. The client device may issue a query to the server device and may receive a second set of data using a second communication protocol. The second set of data may comprise information associated with each of the plurality of data points comprised in the first set of data. A data map may be created based on the first set of data and second set of data, and the client may be at least partially configured automatically based on the data map.

Abstract: Disclosed is a control system for a water network. The control system includes a plurality of remotely-located monitoring and or monitoring and automatic control stations each including an automation controller for local control and automation, and each in communication via a dual-ring communication topology for system or wide-area control. The dual-ring facilitates redundant peer-to-peer data exchange to provide upstream and downstream water flow and water quality information. Systems described herein may calculate flow differential based on water flow data from each of the monitoring stations, and control flow based on the calculated flow differential.

Abstract: The present disclosure provides systems and methods for generating a system-wide event report for electrical power delivery systems. A monitoring device within the power system may generate a key message upon the occurrence of a predetermined condition. A master IED within the power system may generate and/or transmit a system-wide key message to a plurality of monitoring IEDs within the power system. Digital process bus data, continuously recorded by a plurality of monitoring IEDs within the power system, may be saved locally by each monitoring IED within the power system and retrieved by a master IED within the power system. Alternatively, digital process bus data may be transmitted to a master IED and saved locally. A software and/or hardware module may be used to merge the local reports into a system-wide event report.

Abstract: Systems and Methods are disclosed for providing measurement data redundancy to intelligent electronic devices (IEDs) in an electric power system, without additional redundant components. In various embodiments, a first measurement device obtains measurement data from a first portion of the electric power delivery system. A second measurement device obtains measurement data from a second portion of the electric power delivery system. A first IED monitors the first portion of the electric power delivery system based on measurement data associated with the first portion of the electric power delivery system, and a second IED monitors the second portion of the electric power delivery system based on measurement data associated with the second portion of the electric power delivery system. Assuming the first and second portions are coordinated, a communication system dynamically routes measurement data from the second measurement device to the first IED upon a failure of receiving digital measurements from the first measurement device.

Abstract: The present disclosure pertains to systems and methods to identify high-priority traffic within a software defined network (“SDN”) and to route such traffic through physically distinct communication paths. Such routing may help to reduce network congestion faced by high-priority traffic and increase the reliability of transmission of such data. Certain embodiments may further be configured to generate a failover communication path that is physically distinct from a primary communication path. Still further, certain embodiments may be configured to suggest enhancements to a network that may improve a reliability criterion.

Abstract: Systems and methods are presented for managing physical access to an access-controlled area using a local access control system. In certain embodiments, information that may be used in access control determinations managed by a remote domain controller may be communicated to a local access control system for use in connection with local access control determinations performed by the access control system independent of the domain controller. In some embodiments, such a configuration may allow for access control determinations to be performed when communication with the domain controller is interrupted and/or otherwise limited.

Abstract: The present disclosure pertains to systems and methods for establishing communication with a remote communication device in a software defined network (SDN) during time when an SDN controller is unavailable. In one embodiment, a local communication device may be configured to receive a plurality of data flows from an SDN controller and to store the plurality of data flows in a persistent data memory. The device may generate a unique identifier for the local communication device that is transmitted to a remote communication device. Following a disruption the results in the SDN controller being unavailable, the local communication device may recover into a default configured state based on the plurality of data flows in the persistent data memory. The local communication device may then transmit the unique identifier to the remote communication device after the disruption to begin a process of reestablishing communication with the remote communication device.

Abstract: The present disclosure relates to systems and methods for balancing electrical generation and electrical demand in an electrical power system. In various embodiments, a controller may receive priority designations associated with a plurality of loads and inertia of a plurality of electrical generators. A trigger event analysis subsystem may detect a trigger event based on electrical conditions at a plurality of nodes within the electrical power system. A topology detection subsystem may identify a first subset of the plurality of nodes at which electrical conditions reflect the first trigger event and may associate those nodes in an electrical island. An electrical balancing system and control system may be configured to determine and eliminate an imbalance between electrical generation and electrical demand based on the combined inertia of the subset of the plurality of electrical generators and the plurality of priority designations associated with the subset of the plurality of loads.

Abstract: Disclosed herein are methods for detecting and correcting a fault induced delayed voltage recovery event in an electric power transmission and distribution system. In some embodiments, a fault detection subsystem may receive an indication of a fault in the electric power transmission and distribution system. The system may also include a load analysis subsystem to analyze a plurality of loads supplied by the electric power system and to generate an estimated response of the loads. A fault analysis subsystem may analyze a plurality of factors relating to the fault and to determine a probability of the fault generating a fault induced delayed voltage recovery event. A control system may then implement a control strategy within a control window following the fault based on the probability of the fault generating a fault induced delayed voltage recovery event and the estimated response of the at least one load.
