Description

Automatic construction method and system for power grid operation simulation scheme library

Technical Field

The invention belongs to the technical field of power dispatching automation, and particularly relates to an automatic construction method and system for a power grid operation simulation scheme library.

Background

The dispatcher training simulation system (Dispatcher Training System, DTS for short) provides a high-efficiency and convenient platform for dispatcher professional skill training and combined anti-accident exercise, and plays a vital role in improving the service analysis research capability and the comprehensive accident handling capability of regulatory personnel. With the continuous promotion of the construction of the alternating current/direct current hybrid power grid and the explosive growth of the new energy grid-connected scale, the power grid operation characteristics are increasingly complex, and the difficulty of the initial operation mode generation and the tide debugging work of the power grid dispatching power grid operation simulation scheme is increased. However, the current DTS has low intelligent level, the debugging flow of the power grid operation simulation scheme is complex, the power grid operation simulation scheme still needs to be manually compiled by an experienced instructor, and the instructor needs to participate in the exercise training simulation to guide the solution of the trainee to pre-store the power grid faults, so that the workload is high, and the time and the labor are wasted; in addition, the current DTS drilling training simulation power grid operation simulation scheme is seriously insufficient in resources, the power grid operation simulation scheme is usually aiming at a specified fault type and does not carry out systematic classification management, the requirement of a dispatcher on specific training drilling content in online drilling training simulation cannot be met, the dispatcher cannot learn drilling and training is not systematic and insufficient, the drilling and training content is not strong in pertinence and low in practicability, the requirement that a plurality of dispatchers participate in training and personalized drilling and training simultaneously is hardly met, and the DTS cannot become a daily and autonomous simulation tool for the dispatcher to drill and train on demand at any time and any place.

The existing training teaching plan generation method only pays attention to whether the initial running condition of the power grid generated by the DTS system is consistent with the content of the training teaching plan, does not consider complicated and changeable power grid fault conditions contained in the teaching plan, does not provide a method for automatically generating a standard solution for solving the power grid fault, and cannot realize autonomous and personalized training of students. In addition, if a feasible solution cannot be obtained by changing the operation parameters of the power grid equipment according to the power flow calculation result, the method needs to change the constraint conditions of the teaching plan, does not explain how to adjust the initial constraint conditions of the teaching plan in an automatic mode, and still needs to rely on manual experience by a teacher to adjust the original teaching plan and reuse the method to obtain the feasible solution.

In the above embodiment of the present invention, step 3) generates a preset fault of the power grid operation simulation scheme based on the power grid operation simulation scheme fault theme and the power grid fault handling plan, and perfects the power grid operation simulation scheme feature model. The grid fault handling scheme is necessary reference text in the fault handling process, and comprises important data such as transformer substation profiles, fault phenomena, emergency handling measures and the like.

Because the fault handling plans are relatively regular, the content is uniform, the editing format is uniform, the fault handling plans belong to semi-structured data, and knowledge extraction can be realized in a keyword extraction mode through regular expressions. The extracted faults are divided into three types of direct current faults, alternating current faults and cascading faults of the preset faults of the power grid operation simulation scheme, and a preset fault library is formed. The specific types of preset faults are as follows:

1) Direct current fault: the direct current fault theme mainly relates to direct current system faults, and the direct current system faults comprise grounding and disconnection faults of a direct current line, valve bank faults, converter transformer faults, alternating current field faults and the like. Wherein the valve block failure includes monopolar lockout, bipolar lockout, etc.

2) Ac fault: including equipment faults such as transformers, bus bars, ac lines, generators, switches, etc.

3) Cascading failure: because a certain device in the power system breaks down, a series of cascading failures of other devices are caused to stop running, and the cascading failures belong to more complex faults in the power system. For example, after the line switch fails, the line fails to cause the transformer to lose power due to the transformer protection action.

In addition, according to the equipment type, a preset fault library can be expanded, and the fault diversity of the power grid operation simulation scheme is increased.

For example, if the ac fault classification of the original plan library includes the ground fault of the transformer a, the ground fault of the transformer B may be added as an extended fault into the preset fault library.

And randomly selecting the faults meeting the requirements from a preset fault library according to different power grid operation simulation topics for fault handling to generate preset faults of a customized power grid operation simulation scheme.

In the above embodiment of the present invention, after the treatment schemes A1 to An are obtained in step 4), a result evaluation system is compiled based on the power grid operation simulation scheme, and the treatment scheme with the highest score is selected as the optimal treatment scheme. The power grid operation simulation scheme programming result evaluation system is as follows:
