s4, generating at least one planning line path comparison scheme by the grid intelligent planning module according to the names of the starting point and the ending point of the line and the pure overhead type, the pure cable type and the overhead-cable mixed type, comprehensively sequencing selected schemes in each type of scheme according to the sensitivity degree and the line investment, sending the comprehensive sequencing to a planning client, and confirming a final planning line scheme by the planning client and storing the final planning line scheme in the power pipe network resource data storage module;
step S5, judging whether all planning lines sent by the planning client are processed completely, if not, carrying out step S2, and if so, sending a summary list of each planning line path, overhead or cable line length, line section, investment and line sensitive points to the planning client;
step S6, after the data in the power grid data storage module is updated, the power grid resource condition is evaluated based on the updated current line path or confirmed planning line path data, if an unreasonable planning condition exists, early warning information is generated and sent to a planning client, and if the unreasonable condition does not exist, evaluation passing information is generated and sent to the planning client; the evaluation of the power network resource condition specifically comprises the following steps:
generating a power transmission line distribution diagram of each overhead corridor section, each utility tunnel, each cable tunnel and each cable trench, and for planning lines meeting the requirement that the capacity of the remaining lines of the overhead corridor is less than or equal to 2, or the positions of the remaining power transmission cables of the utility tunnels and the cable tunnels are less than or equal to 2, or the positions of the remaining power transmission cables of the cable trenches are less than or equal to 1, listing the planning lines into a space shortage section list, and generating early warning for the space shortage range;
generating planned line production year and a planned comprehensive pipe gallery, a cable tunnel and a planned road cable trench construction year comparison table which are not built, and generating red early warning for the comprehensive pipe gallery, the cable tunnel and the planned road construction which are later than the planned line production time; and (3) not putting into production for the comprehensive pipe rack, the cable tunnel and the planned road, but planning is earlier than putting into production for the line, so that yellow early warning is generated.
2. The method according to claim 1, wherein in step S2, the contents of the generating an exact match list and a fuzzy match list are:
recording accurate matching results in the accurate matching list, wherein the accurate matching results are search results with the same or the same line starting point and ending point as the planned line;
and recording the fuzzy matching result in the fuzzy matching list, and comparing the fuzzy matching result with the search result of which the planned route is partially overlapped with one or more route paths.
3. The method as claimed in claim 2, wherein in step S4, the pure overhead planning line is specifically that all or a line with a set length ratio is located in an overhead corridor, the set length ratio is 0.9 of the total length of the line, and the line path avoids a sensitive area.
4. A method according to claim 3, wherein in step S4, the planned routes of the pure cable are specifically routes with all or a set length ratio, which is set to 0.9, in the utility tunnel, the cable tunnel or the cable pit.
5. The method of claim 4, wherein in step S4, the overhead-cable hybrid planning line is specifically that the number of type transitions does not exceed a set value over the entire length of the line, the overhead portion is routed along an overhead corridor, and the cable portion is routed along a utility tunnel, a cable tunnel, and a cable pit.
