摘要： A technique for a control method and a control system in a substation is provided. The control system includes a substation feeder, an intelligent electronic device, IED, a merging unit, and BUS network connecting the IED and the merging unit. The control method includes providing measurement signals by the substation feeder to the merging unit, transmitting, by the merging unit, measurement data based on the measurement signals of the substation feeder to the IED via the BUS network, identifying, by the IED, a fault condition based on the measurement data, transmitting, by the IED, a conditional control command to the merging unit via the BUS network, determining, by the merging unit, whether the condition of the conditional control command is met, and if so initiating, by the merging unit, the control measure of the substation feeder circuit.
