A system for autonomous control in power systems is disclosed. In particular, a secure overlay communication model (SOCOM) is disclosed, the system including a combination of hardware and software for detecting power grid states, and determining appropriate actions for addressing detected states. The SOCOM is a logic-based system deployed onto computing devices such as field programmable gate arrays installed at bus controllers, Supervisory Control and Data Acquisition Systems (SCADAs), Intelligent Electronic Devices (IEDs), or other computing devices in power grid stations and substations. The logic-based nature of the SOCOM allows for seamless integration with preexisting power system equipment. In response to detecting various power grid faults such as line failures and over-current states, the system automatically rearranges power line configurations at the power stations and/or substations. The SOCOM further provides improvements relating to optimal power flow, cost-based power distribution, load management, voltage/volt-amp reactance (VAR) optimization, and self-healing.

A system and methods for managing a transformer area in an electrical distribution grid having at least one substation transformer and one service transformer are presented. At least one Remote Hub governed by a policy may be provided, which collects data about the transformer area. The Remote Hub may also execute a discovery procedure to inventory Remotes in the transformer area. The Remote Hub may use the collected data to detect events, such as exceptional conditions, configuration changes, or derived results, within the transformer area. Based on the collected data, the Remote Hub is able to transmit data about the transformer area via a Substation-to-Edge channel. A method and system for forming and establishing boundaries of Transformer Area Networks is also presented. Discovery procedures may be used to form Transformer Area Networks out of Remote Hubs and Remotes powered by the same phase of the service transformer.

The application relates to a software-defined realization method based on a protection and control system for an intelligent substation. According to the application, the intelligent substation adopts a centralized modeling manner of directly adding and updating all of a protection, a measurement and control, an exchange and a telecontrol functions in substation configuration descriptions by taking the whole substation as a modeling object, instead of a decentralized modeling manner of sequentially adding a single physical apparatus and then adding functions of each apparatus adopted by a traditional substation. Since SCD files of the intelligent substation are created based on merging unit and intelligent terminal integrated devices and special functions planned by the intelligent substation, and configuration information of each of the special functions is set in the SCD files of the intelligent substation, an aim of defining the special functions of the intelligent substation through software is achieved.

The invention relates to a recovered electric power measuring system comprising at least one processor; at least one memory storing computer-executable instructions; and at least one receiver configured to receive data from a sensor on an electrical powerline connected to a generator of a power-recovery turbine, the power-recovery turbine located in a petroleum, petrochemical, or chemical process zone wherein a portion of a first process stream flows through the power-recovery turbine and generates recovered electric power as direct current, the power-recovery turbine electrically connected to a single DC to AC inverter and the output of the DC to AC inverter electrically connected to a first substation.

The present invention is concerned with simplified configuration as well as supervision and testing of load restoration functions in high or medium voltage substations of electrical power transmission or distribution networks. The invention takes advantage of the fact that all information for load restoration is available from a standardized configuration representation and from dynamically observable events. Specifically, the IEC 61850 Substation Configuration Description (SCD) file includes the substation single line, the bus bar or breaker failure protection functionality related to it, and the way how reclosing commands can be conveyed for the restoration process. A load restore function or load transfer application observes the execution of a protection trip function and the concurrent connection state of the bays to bus bars in order to automatically restore the power flow across a failed bus bar segment to a parallel healthy bus bar segment.

An apparatus and method for ensuring the reliability of a protection trip of an intelligent substation. The apparatus comprises a main CPU and an auxiliary CPU connected together, and a main FPGA and an auxiliary FPGA connected together, wherein the main FPGA and the auxiliary FPGA are both connected to a physical layer of a protection apparatus, and the main CPU and the auxiliary CPU are both connected to a state monitoring data output end of a protected device. Wherein, the main CPU sending a processing result to the main FPGA, the auxiliary CPU sending the processing result to the auxiliary FPGA, and the auxiliary FPGA synchronizing current information with the main FPGA after receiving information sent by the auxiliary CPU; and when the main FPGA receives trip information, the main FPGA comparing the consistency of current trip information obtained from the main CPU with that of current trip information obtained from the auxiliary FPGA, and if the two are consistent, the main FPGA sending the information received from the main CPU to the protection apparatus, otherwise, discarding the information received from the main CPU. An anti-misoperation ability of a protection apparatus is improved, and it is ensured that the apparatus cannot cause misoperation of primary device due to unknown errors when a hardware device failure, single event upset (SEU), etc. happens.
