    摘要： A battery energy storage arranged to be connected to a capacitor link, which is connected in parallel to a power converter. The battery energy storage includes a battery module and a direct current energy source connected in series with a voltage source converter. The voltage source converter is adapted to insert a positive voltage when the voltage of the battery module falls below a first threshold value, and to insert a negative voltage when the voltage of the battery module exceeds a second threshold value. The direct current energy source is adapted to be either charged or discharged during the voltage insertion by the voltage source converter. The disclosure also provides a battery energy storage system including such battery energy storage.

    摘要： A protection relay is disclosed that generates a trip signal to operate a circuit breaker in case of a fault condition. A first module provides measurement and analysis of power parameters of the power line connecting the power equipment that is being protected, the protection being provided by generating a first trip signal for operating a circuit breaker connected in the power line. One or more second modules can boost performance of the protection relay by measurement and analysis of power parameters-to generate a second trip signal for operating a circuit breaker connected in the power line. The first trip signal and the second trip signal are logically combined to generate a trip signal that operates the circuit breaker.

    摘要： A Substation Automation (SA) system is configured to perform protection functions for a bay of an electrical power distribution substation, receive, via a communication link, redundancy protection commands from a remote center, and execute the redundancy protection commands for the bay. The SA system is configured to transmit to a redundant protection server of the remote center, process values measured by measurement equipment of the substation, and to receive, from the redundant protection server, and forward, via the process bus, the received redundancy protection commands directed to operating equipment of the substation. Thus, for multiple SA systems, redundant protection functions are implemented and provided cost-efficiently by one common remote central unit.
