Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
In order to at least solve the technical problem provided by the present invention, an embodiment of the present invention provides a power supply system maintenance method.
Fig. 1 is a schematic flow chart of a power supply system maintenance method according to an embodiment of the present invention, and referring to fig. 1, the method according to the embodiment of the present invention may include the following steps:
s11, acquiring basic data, wherein the basic data comprises: at least one of equipment overhaul willingness, equipment unit parameters and network topology parameters.
The overhaul ticket is a written basis and a safety license for overhaul, maintenance, installation, modification, debugging, test and other work (collectively called "overhaul work") of an overhaul worker on a power production site, equipment and a system, and is a written safety contract which is commonly held and commonly and forcibly observed by both the overhaul worker and the operation worker. In the embodiment of the invention, based on NLP technology, the adjustment of the mode of intelligently identifying the maintenance ticket can be realized, the maintenance strategy expert base is intelligently matched, the fuzzy and brief descriptive language in the maintenance ticket is converted into the accurate and comprehensive object language which can be identified by a computer, and the accurate and comprehensive object language is used as basic data to provide decision basis for planning.
In a specific maintenance process, a power supply system of a certain power supply office can be defined as a target power supply system, and the maintenance module of the target power supply system can execute the maintenance process of the invention. The target power supply system is connected with each data input device through an interface, for example, the basic data can be obtained through the interface or a manual input mode, and the basic data may include: at least one or more of equipment overhaul willingness, equipment unit parameters and network topology parameters. Wherein, the network topology parameter is the power grid topology parameter: topology information, topology change information and actual line parameters of the power grid in a maintenance plan decision period. The equipment overhaul intention and the equipment unit parameters can be acquired according to the specific conditions of the equipment.
And S12, judging the rationality of the basic data based on the preset verification rule.
After the basic data is acquired, in order to ensure the accuracy of the data, the rationality of the basic data can be judged based on a preset verification rule. Meanwhile, the rationality and the practicability of the maintenance plan need to be guaranteed by real and reasonable input data, so that data rationality inspection needs to be carried out before maintenance plan optimization calculation is carried out.
When the rationality of the basic data is judged, bad data detection and identification, rationality detection and identification, model rationality inspection and the like can be performed. And if any one of the problems is detected, sending a data correction request, correcting the basic data, and then using the corrected basic data as the basic data to perform rationality verification.
And S13, when the basic data are reasonable, determining a maintenance plan according to the basic data and maintenance plan acquisition rules, wherein the maintenance plan is a multi-time-sequence maintenance plan.
Specifically, after the rationality verification of the basic data passes, an inspection plan may be determined, where the inspection plan is a multi-time-series inspection plan, and may be, for example, a weekly inspection plan, a monthly inspection plan, a quarterly inspection plan, an annual inspection plan, or the like.
Optionally, determining the maintenance plan according to the basic data and the maintenance plan obtaining rule includes: determining a maintenance plan model according to the basic data and the input parameter requirements of the solving algorithm; and solving the maintenance plan model based on linear mixed integer programming or equal standby equipment maintenance heuristic algorithm to obtain a maintenance plan.
For example, the basic data can be organized according to the input parameter requirements of the solving algorithm, and an annual/monthly overhaul plan model can be established. In the specific modeling process, the calculation efficiency of the model and the robustness of the model are improved by following the principles of completeness, operability and high efficiency of modeling and combining the sparse technology and the relaxation technology, and in the modeling process, a person skilled in the art can perform the calculation according to the solving algorithm provided by the embodiment of the invention, and details are not repeated here.
And S14, checking the maintenance plan based on the maintenance plan checking rule to obtain a target maintenance strategy.
Optionally, based on the inspection rule of the inspection plan, the inspection plan is inspected to obtain a target inspection strategy, including: based on the feasibility inspection rule, inspecting the maintenance plan to obtain a feasibility inspection result; and/or, based on the operability test rule, testing the maintenance plan to obtain an operability test result; and if the feasibility test result or the operability test result is abnormal, revising the maintenance scheduling model.
After the modeling is successful, the model may be solved, for example, the annual maintenance plan model or monthly maintenance plan model may be solved through linear mixed integer programming (MILP) or an equipment maintenance heuristic algorithm based on equal redundancy (liability rate), and the solving process is known by those skilled in the art, and thus is not described herein again. And after the model is solved, acquiring a maintenance plan, and in order to ensure the safety of the maintenance plan, performing safety check on the maintenance plan so as to acquire a target maintenance strategy.
In this embodiment, it is considered that all or part of the models need to be solved by using optimization software, and due actual physical background of the power system is lacked, so that the rationality of the solution result cannot be judged in the solution process in deep software. Therefore, the solving structure can be overhauled and inspected aiming at the solving result of the model, and the correctness and the physical significance of the solving result are ensured; and feeding back and modifying a modeling link aiming at unreasonable results and the defects of the model to be quickly positioned.
For example, the feasibility of solving the results can be examined: if the model has no feasible solution, the existing mature optimization software gives the best infeasible solution and gives related information. At this time, the reason why the model is infeasible and the existing problems need to be quickly located by combining software output information and the solving result of the relaxation variable added in the modeling process and contrasting the calculation result and the model constraint condition, so that the solving efficiency is improved.
For example, the operability of the solution may be examined: because of the existence of some non-analytic constraints in the maintenance plan model, constraints can only be added to the optimization model by simplifying the modeling. Therefore, the solution results of the model may not fully meet the requirements of these practical operating constraints. At this time, it is necessary to locate the problem of the maintenance plan model by other constraint detection strategies or manually, and modify the maintenance plan model.
If any one of the model solving results is unreasonable, unreasonable information needs to be fed back to the data abstraction and model building module, and the maintenance plan model is modified and then solved again, so that the target maintenance strategy is obtained. For example, when an abnormality occurs in a line, a cross section, or the like, limit control or the like is performed, and an inspection plan is newly created by adding an inspection plan correction constraint.
And S15, overhauling the target power supply system according to the target overhauling strategy.
And after the target maintenance strategy is obtained, the target power supply system is maintained according to the target maintenance strategy.
According to the power supply system maintenance method provided by the embodiment of the invention, the rationality of basic data is judged and the maintenance plan is checked through the computer, so that the intelligent arrangement level of the maintenance plan is improved, and the requirement of market environment on maintenance service is met.
Optionally, on the basis of the foregoing embodiment, in order to ensure normal operation of the maintenance plan, the method may further include: evaluating the target maintenance plan according to a preset evaluation index to obtain an evaluation result; if the evaluation result is abnormal, analyzing the abnormal reason of the evaluation index, and acquiring the maintenance plan correction constraint according to the abnormal reason; and correcting the constraint according to the maintenance plan and correcting the target maintenance strategy.
For example, after the maintenance plan passes the verification, a quantitative evaluation index can be calculated, and the quantitative evaluation index can guide a maintenance planning operator to continuously perfect the work and ensure an effective hand grip of the maintenance planning quality. Presetting evaluation indexes, which can be indexes of adaptability, economy, energy conservation and fairness, and issuing execution after the indexes are qualified; if the indexes are unqualified, the reasons are found out, the maintenance plan correction constraint is formed, and optimization calculation is carried out again.
In the embodiment of the present invention, basic checking may also be performed on a monthly maintenance plan, basic checking based on expert experience on the monthly plan is supported, and checking may be performed on a plurality of information items, including but not limited to: whether power supply equipment is protected, whether a year plan is listed, whether power failure is repeated in excess of the year, whether power failure is repeated within 3 months, the correct integrity of a maintenance plan, whether the plan is repeated, whether a bill can be built, whether a mutual exclusion constraint is violated, and a single-day power-off operation amount constraint. The method comprises the steps of adjusting in a monthly planned month caused by weather, personnel, materials and the like, performing dynamic checking, and performing risk prompt on adjustment with conflict; and (4) forming completed log records by schedule change, cancellation and addition of the plan in the month as basic data of scheduling safety evaluation.

For example, in order for an optimized service plan to be feasible, several constraints must be set according to the specific conditions of the power system, while safety checks and congestion management are performed. And compiling a power grid risk early warning notice on the basis of monthly plan risk analysis. And forming a key checking section based on the multi-time sequence maintenance plan, and sending the key checking section into a safety checking program for checking. And if the section which cannot pass the safety check exists in the maintenance plan, the planning function module constructs the maintenance plan correction constraint by combining the information fed back by the safety check, feeds back the maintenance plan correction constraint to the planning optimization model and the flow, and modifies the maintenance plan until the requirement of the safety check is met.
Referring to fig. 2, closed-loop safety check of the power failure plan is realized, and a check result and a closed loop of maintenance optimization adjustment are realized according to specific out-of-limit information and a corresponding adjustment scheme aiming at the condition that the check does not pass. The security check strategy should support the setting of the power grid equipment N-1 and the fault set. Supporting the tide result, heavy load and out-of-limit information of output lines and sections; and the equipment N-1 checks and the fault set checks information, and provides comprehensive power grid maintenance risk point analysis.

After a basic state overhaul plan is obtained, namely the overhaul plan is obtained, an overhaul check analysis and decision module part checks the basic state overhaul plan, if the check does not pass, overhaul basic state blockage management is carried out, if the check passes, N-1 safety check is carried out, and if the N-1 safety check does not pass, N-1 correction is carried out; if the N-1 safety check is passed, performing fault check, and performing fault set correction when the fault check is failed; and obtaining a plan checking result after the fault checking is passed, obtaining a target maintenance plan after the plan checking result has no problem, and issuing the target maintenance plan. And if the plan checking result is abnormal, adjusting according to the modification suggestion, checking the closed loop to the basic state checking plan, and checking again.
Optionally, the method further includes: and based on the SVG, displaying the maintenance strategy according to at least one of preset dimensionality, preset display means and preset visualization rules.
