The invention provides a method and system for generating a scheduling item operation order. The method includes the steps of reading EMS data, judging whether an equipment position state is consistent with an equipment real-time state, if yes, generating task selection according to the operation conducted by an order drafter on equipment to be operated, generating an operation item with the position state opposite to the position state of the equipment according to the operation conducted by the order drafter on equipment in a transformer substation, judging a power source point of a factory and a power source point of a station according to an active power grid power flow diagram, a positive power grid flow diagram and the equipment position state when the switching of the operation method of a power grid is related, and when the power source point of the factory and the power source point of the station are converted into new power source points after the judgment operation, generating a secondary operation item which needs to be changed, wherein the EMS data include the active power grid power flow diagram, the positive power grid power flow diagram and the equipment position state, and the secondary operation item includes a reclosing device and automatic bus transfer equipment. According to the method and system, the order drafting speed is improved, the operation risk of the power grid is lowered, and a large number of paper resources are saved.
