The invention relates to a same-rod and multi-loop zero-sequence current protection method and device. The method comprises the steps of determining zero-sequence currents of a circuit and an adjacentcircuit; acquiring a zero-sequence mutual induction coefficient of the adjacent circuit on the circuit, and determining a compensation coefficient of the adjacent circuit according to the zero-sequence mutual induction coefficient of the adjacent circuit on the circuit; determining the zero-sequence current of the circuit after compensation according to the zero-sequence currents of the circuit and the adjacent circuit and the compensation coefficient of the adjacent circuit; and starting zero-sequence current protection action on the circuit according to the zero-sequence current of the circuit and the zero-sequence current of the circuit after compensation. According to the method provided by the technical scheme of the invention, the zero-sequence current of the adjacent circuit is introduced to a zero-sequence current protection criterion of the circuit, the misoperation of zero-sequence current protection of the circuit can be effectively prevented, and the safety of the zero-sequence current protection is improved.
