The application of IEC61850 standard and the development of smart terminal unit (STU) technology provide a powerful platform for secondary protection research of distribution network. Aiming at the problems of override trip in the protection of the incoming line and feeders on traditional 10kV switching stations, a scheme combining distributed voltage loss protection and overcurrent protection is proposed. The smart terminal unit collects and processes the operation data, realizes data exchange through GOOSE network communication, and cooperates to realize the protection function of the switch stations. In this paper, a protection logic diagram based on the GOOSE mechanism is constructed, which realizes the protection function of feeder lines fault lockout incoming line breakers and the bus line fault lockout busbar automatic transfer switch.
