step S1, checking a switch and drawing;

s2, checking topology coloring;

s3, checking the switch state;

s4, checking terminal numbers and repeating;

s5, checking a topological structure;

and S6, checking the state of the transformer.

In particular, in step S1, the process of drawing the check switch is as follows: checking whether the GIS has the switch or not, and stopping the switch equipment to judge whether the type drawing error exists or not.

Example 1, after a 110kV suburban station collaboration line 626 new junction 18 pole 2103 switch was pulled, no power outage equipment was analyzed, and a view of GIS found that 2103 switch was plotted on the branch of the new junction 18 pole, as shown in fig. 1, and no equipment was connected below 2103 switch, resulting in pulling 2103 switch, no equipment was analyzed. The actual drawing should be at the middle section position of the 18# rod and the 19# rod as shown in fig. 2.

In this embodiment, the type of drawing error includes that the segment switch is drawn as a branch switch.

In particular, in step S2, the topology finding coloring process is as follows: and checking whether equipment in the power failure range in the GIS is electrified color or not, and whether equipment power failure caused by the disconnection of a superior power supply exists or not.

Example 2, as shown in fig. 3, the new rock drop 664 in-station switch is off power loss color.

In particular, in step S3, the switch state checking process is as follows: check if the 10kV tie switch and the distribution room low-voltage tie switch are in the closed position.

Example 3, as shown in fig. 4, a village station 772 left north line and no equipment was analyzed after pulling in the pull station. The search reasons are shown in fig. 5: the 10kV525 Tengshen is powered back to the 772 North line through a 1907# pole breaker. The solution is shown in fig. 6: pull open the 10kV525 Teng wire 1907# pole breaker.

Example 4, as shown in fig. 7, the suburban station 626 was pulled to cooperate with the in-station switch to analyze the blackout condition. The search reasons are shown in fig. 8: the suburban western station 10kV cable 693 supplies power to the suburban western station 626 in a coordinated line reversal through the low voltage tie switch in the 10kV2552# electric switch station Kang Yuan. The solution is shown in fig. 9: the low-voltage interconnection switch in the electric switch station Kang Yuan of 10kV2552# is pulled open.

In this embodiment, in step S4, the terminal number checking repeat process is as follows: switching off the switching device, analyzing the power point of the device through the power point tracing function, and searching the line string point; the terminal number is reset.

In this embodiment, a dichotomy and an observation method are used to find the line cross points.

In particular, the present embodiment resets the terminal number by deleting the redrawing problem device or employing the node editing function.

Example 5, as shown in fig. 10, the power point analysis was performed by pulling the switch in the Xinhua station 347, selecting 347 north out the upper line super link line without power failure. As shown in fig. 11, a cross-wire condition occurs due to the same terminal number.

In particular, in step S5, the topology checking process is as follows: whether transformer equipment exists under the power failure switch equipment or not, and whether the double-power equipment is powered by a power failure line or not.

Example 6, as shown in fig. 12, 10kV kunlun line 433 south Zhuang Louou distribution room at the Yangtze river station, south village # 7, 6# 5 distribution transformers are double power supply, GIS graph shows 433 kunlun line power supply, 772 north line is standby power supply (pull-open state). According to the field feedback, the power supply connected with the three distribution transformers is 772 north-left wire, and the connecting switch of the power supply and 433 Kunlun wire is in an off state, which is opposite to the switch state of the GIS graph, so that the power failure information and the field actual situation are abnormal.

In particular, in step S6, the process of checking the transformer state is as follows: the system status of the transformers PMS and 186 in the power outage range is checked to see if the system is running and if the system is taken down by the user 186.
