[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0035] According to an embodiment of the present invention, an embodiment of a training exercise method for an electric power system is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.
[0036] In this embodiment, a training exercise method for a power system is provided, which can be used for computer devices such as mobile phones, tablet computers, desktop computers, portable notebooks, servers, etc. Figure 1 is a flow chart of a training exercise method for a power system according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:
[0037] Step S101, obtaining the user account information of the power system in different areas.
[0038] Specifically, different regions may be different provinces and regions across the country, for example, Henan Province, Hebei Province, Shandong Province, Shanxi Province, etc. The power system user ledger information may be user ledger information of different provinces and regions, and the user ledger information mainly includes user name, user type, user station number or user pole number, capacity of each transformer of the user, user commissioning time, user change date and capacity load ratio.
[0039] Step S102, based on the power system user account information, generate the authority management configuration information under multiple preset training exercise rooms.
[0040] Specifically, the authority management configuration information includes authority management configuration information corresponding to different user roles. For example, the embodiment of the present disclosure can restrict access to preset training exercise rooms according to the dispatching organization to which the multi-level power grid users belong, control the access rights of the participants to multiple preset virtual exercise rooms corresponding to different regions, and prohibit the participants from cross-regional access and operation. The multiple preset training exercise rooms in the embodiment of the present disclosure are multiple preset virtual exercise rooms, which can be displayed through the display interface. For example, the first preset training exercise room, the second preset training exercise room, the third preset training exercise room, and the fourth preset training exercise room, the screen of each preset training exercise room is basically the same, the difference is that the logged-in users are different, and each preset training exercise room corresponds to a region. For example, the first preset exercise training scenario corresponds to Henan Province, the second preset exercise training scenario corresponds to Hebei Province, the third preset exercise training scenario corresponds to Shandong Province, and the fourth preset training exercise room corresponds to Shanxi Province.
[0041] In some optional implementations, based on the power system user account information, authority management configuration information under multiple preset training exercise rooms is generated, including:
[0042] Step a1, grouping all users in the power system user ledger information according to different areas, exercise roles, and the number of preset training exercise rooms. The exercise roles include administrators, instructors, and trainees.
[0043] Step a2: Based on the grouping results, the access rights and access time for logging into the corresponding preset training exercise scenario are set for each group of users according to the exercise role.
[0044] Specifically, when configuring permission management information, different users in a multi-level power grid can be divided into groups according to user usage habits, different provinces, exercise roles, and the number of virtual exercise rooms. For example, according to Henan Province, multiple power grid users in Henan Province are assigned to corresponding preset training exercise rooms, or multiple power grid users in Henan Province and Hebei Province are assigned to corresponding preset training exercise rooms. The corresponding user roles in each preset training exercise room can be administrator, instructor, and trainee, respectively, and based on the grouping results, the access rights and access time for logging into the corresponding preset training exercise scene are set for each group of users according to the exercise role.
[0045] In the grouping results, groups are required to manage dispatchers in groups, and the same group enters the only designated virtual exercise room; in the exercise role, the administrator has the authority to control the opening and closing of the virtual exercise room, the instructor has the authority to set power grid faults and control the exercise process in the virtual exercise room, and the trainee is the role used to be assessed.

[0049] The following Table 2 is a schematic diagram of a preset training exercise room.
[0050] Table 2
[0051]
[0052]
[0053] Specifically, based on the grouping results, the grouped personnel enter the corresponding preset virtual exercise room to complete training exercises in different provinces and regions, and the same group of users is automatically assigned to the same preset training exercise room.
[0054] Step S103, making a power system fault simulation teaching plan based on the power grid topology model.
[0055] Specifically, the power grid topology model is created based on the power grid nodes and edges and endowed with power grid attribute information, and the power system fault simulation lesson plan is the content used for exercises in a preset virtual exercise room.
[0056] In some optional implementations, a power system fault simulation teaching plan is prepared based on the power grid topology model, including:
[0057] Based on the power grid topology model, the line names, line parameters, and line status of different areas are obtained to make power system fault simulation teaching plans.
[0058] In a specific example, the line name is used to distinguish the lines, and the line parameters include: nominal impedance, maximum current carrying capacity, load parameters, number of transformer windings, bus voltage parameters, and generator parameters on the lines in different areas.
[0059] In another specific example, the line state includes a switch closed state and a switch open state.
[0060] In a specific example, the power system fault simulation lesson plan includes: short circuit fault simulation lesson plans in different areas, open circuit fault simulation lesson plans, busbar faults, transformer fault simulation lesson plans, and switch fault simulation lesson plans.
[0061] Step S104, based on the power system fault simulation teaching plan, execute the power system training exercise actions in a plurality of preset training exercise rooms according to the authority management configuration information.
[0062] Specifically, after completing the collaborative production of training exercise lesson plans in the virtual exercise room, the power system background simulates the data calculation service process of the power grid operation mode, and conducts continuous disturbance simulation on the power system to track the 24-point output and power generation data, and continuously matches the dynamic flow of power generation output in the background, so that the power system can quickly converge and calculate the real-time frequency of the current simulated power grid. In the corresponding power system fault simulation lesson plan, the fault setting and operation mode adjustment operations are performed to execute the training and exercise of the power system training exercise actions.
[0063] Specifically, the operating mode adjustment in the training exercise refers to the operation of electrical equipment on the plant single-line diagram in the virtual exercise room, including: opening and closing operations of switch blades, load active and reactive power adjustment, unit active and reactive power adjustment, and winding gear adjustment.
[0064] In the virtual exercise room, each group of users has access and operation rights to the plants and stations under the jurisdiction of their own dispatching agency, and the power system prohibits access and adjustments across jurisdictions.
[0065] In a specific example, the training exercise method for the power system in the embodiment of the present disclosure further includes:
[0066] Comprehensively score the training exercises of the power system executed in multiple preset training exercise rooms and generate a scoring report.
[0067] Specifically, after the training or exercise, the power system will give a comprehensive score based on the compliance, safety, and economic efficiency of the fault handling process to form a scoring report for this virtual exercise room.
[0068] In a specific example, after the drill is over, the administrator actively applies to close the virtual drill room, and the power system will immediately reclaim the instance scene where the preset virtual drill room is located, or automatically reclaim the instance scene resources after the default duration of creating the preset virtual drill room is reached to avoid overtime occupation of resources.
