    摘要： This disclosure relates to systems and methods for configuration-less process bus. An example system 200 includes at least one process interface unit, PIU 135. The PIU 135 includes at least one pre-configured communication port 225 defined by one of a factory setting or a product code order. The at least one PIU 135 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 115 or a voltage transformer 120. The dataset can further include a timestamp and a unique identifier associated with the source. The system includes at least one intelligent electronic device, IED 145 communicatively coupled to the PIU 135. The IED 145 is operable to receive the data stream from the PIU (135) and transform the sampled values based on user-defined transformation factors. The IEDs 145 may include a pre-configurable and configurable processing 210 of datasets received from at least one of the PIU/MUs 135. Data stream between PIU/MUs 135 and IEDs 145 is formatted based on the IEC 61850 or IEC 61869 format. The PIU/MU 135 can specify a fixed (factory provided) pre-configuration (including a unique identifier) using an IED Instantiated Description (IID). The PIU/MUs 135 may not need a configured IED description (CID) file for configuration. Therefore, the PIU/MUs 135 may not require any configuration at the installation site. An engineering computer 220 may be needed for an initial configuration of the IEDs 145 and the LAN 230.

PIU / MU 135和IED 145之间的数据流基于IEC 61850或IEC 61869格式进行格式化。 PIU / MU 135可以使用IED实例化描述（IID）来指定固定（工厂提供的）预配置（包括唯一标识符）。 PIU / MU 135可能不需要配置的IED描述（CID）文件来进行配置。 因此，PIU / MU 135可能不需要在安装现场进行任何配置。 工程计算机220可能需要用于IED145和LAN230的初始配置。

    摘要： 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 (6.5, 6.6, 6.7) to bus bars (1.1, 1.2) in order to automatically restore the power flow across a failed bus bar segment (1.1) to a parallel healthy bus bar segment (1.2).

    摘要： A method and a system are described for monitoring a grid voltage in a low voltage grid, where the low voltage grid (1) is connected through a local grid transformer (2) in a substation to a medium voltage grid (3) and where at least one power generation installation is connected to the grid. The following steps are performed: calculating a reference voltage rise in the grid (Δu ref ) under the assumption that at a given reference power flow on the low voltage side of the local grid transformer (P Tr,ref ) and at no loads, an exemplary distribution of the at least one power generation installation supplies a maximum power to the grid; determining the present voltage (u LV,SS ) and the present power flow (P Tr ) on the low voltage side of the local grid transformer from corresponding current and voltage measurements; determining the present voltage rise (Δu) from the ratio of the present power flow (P Tr ) to the reference power flow (P Tr,ref ); and determining the present critical voltage in the grid (u LV,crit ) as the sum of the present voltage (u LV,SS ) and the present voltage rise (Δu).

    摘要： A circuit breaker protection system (100) includes a plurality of circuit breakers (106, 107, 108), each circuit breaker (106) of the plurality of circuit breakers (106, 107, 108) including a trip device (161) and a shunt trip device (162), and a first central processor (101) in communication with each circuit breaker (106) of the plurality of circuit breakers (106, 107, 108), the first central processor (101) being configured to perform a method of circuit breaker control. The method includes determining a status (305) for each circuit breaker (106), transmitting a trip signal (306) to each circuit breaker (106) based on a respective circuit breaker's status, establishing a priority (307) of each circuit breaker (106) in response to a respective circuit breaker's trip signal, and transmitting a shunt trip signal (404, 405) to each circuit breaker (106) based on a respective circuit breaker's priority.
