The scale and the quantity of local power grids are continuously enlarged, the tasks of capital construction, technical improvement and power grid equipment maintenance are various, and the maintenance abnormal signals generated along with the tasks are more and more. When the equipment needs to be restored to the power supply during maintenance, if abnormal signals related to the equipment still exist on the alarm window of the energy management system and are not restored, such as abnormality of a line protection device, disconnection of a switch control loop and the like, the safety of the equipment during restoration of the power supply is affected, and the equipment can trip in the power transmission process and even cause more serious consequences, so that the stability of a power system is endangered.
The traditional method is that before a certain device is reset, a power dispatcher manually checks whether a related unreset signal of the device exists in an alarm window of an energy management system, and judges whether the unreset signal affects the reset of the device. If the signal affecting the power restoration safety of the equipment is abnormal, such as the abnormality of a line protection device, the disconnection of a switch control loop, the abnormality of a bus differential protection device and the like, the power transmission of the equipment is allowed after the signal is restored. Some lines involve several sides of the substation side, and the signal of each side of the substation is checked before the line is powered. Once a dispatcher neglects carelessness, no signal is checked before power restoration or a signal of a substation on one side is left without being checked, the hidden danger of tripping when equipment is powered back is increased, and the situation that the equipment cannot be lost by manual checking can not be realized.
