The wiring diagram of the power grid system is a drawing mode which is specific to the power system and describes a power grid, does not require precise positioning of power equipment (power plants, substations and lines), but only displays the relative position relation and the connection relation among the power equipment, the power plants, the substations and the lines, and displays the approximate length of the lines and the approximate distance among the equipment. The graph is generally drawn in a single line diagram, and since the electrical parameters of the three phases of the power line are the same, one line can represent three lines. In order to simplify the drawing process, a power grid system wiring diagram can be used as a power grid equipment wiring diagram.

step S10213, marking the result of the anti-error check as qualified;
step S10214, recording the inconsistent comparison instruction, and marking the error-proof result as unqualified.
The flow chart of the second embodiment is shown in fig. 3, and includes:
step S10221, simulating the operation of pre-execution of a scheduling operation order in a pre-established power grid topology model;

The error parameters may cause additional measurement bias to their associated branch power and injection power during the estimation process, which may degrade the final state estimation accuracy as well as the poor measurements in the state estimation. As well as the identification of bad measurements, the measurement deviation is also reflected in the residual, so the error parameters can be identified in a similar way as the bad measurements and identification.
According to the anti-misoperation method for the dispatching operation order, the pre-stored power grid equipment wiring diagram and the real-time collected power grid operation state are displayed on the man-machine interaction interface, so that a dispatcher can bill according to the power grid equipment wiring diagram and the power grid operation state, and operation order errors caused by the fact that the dispatcher bills by depending on memory are reduced.
