Abstract:
A control arrangement for a circuit breaker station includes a central control system and, for each of the circuit breakers, a circuit breaker operating unit connected to the central control system to obtain switching instructions and to the respective circuit breaker to control the operation thereof. The central control system and the circuit breaker operating units each have a local clock that are synchronized with one another. The central control system is, during use, arranged to calculate a point of time for switching each of the circuit breakers based on measured voltages, currents, and circuit breaker positions, and to send the point of time in a switching instruction to the circuit breaker operating unit. Each of the circuit breaker operating units is arranged to switch the circuit breaker, to which it is connected, at the point of time which is received in the switching instruction from the central control system.
