The main problem is that the scenario is provided by the examiner, who needs to communicate with the candidate to confirm it. This is inconvenient to operate and is greatly affected by human factors, resulting in inaccurate evaluation results. Summary of the Invention

[0017] The MCU module is also specifically used to compare the difference between the external point signal and the initial scenario control data. If the external point signal is consistent with the initial scenario control data, the simulated image information is generated based on the initial scenario control data. If the external point signal is inconsistent with the initial scenario control data, the initial scenario control data is updated based on the external point signal to obtain the final scenario control data, and the simulated image information is generated based on the final scenario control data.

[0018] Furthermore, when the external point signal is inconsistent with the initial scenario control data;

[0019] The MCU module is further specifically used to create 4-bit shift storage units VB1 and VB2; store the high 4 bits of the external point signal in the shift storage unit VB1, store the high 4 bits of the initialization scene control data in the shift storage unit VB2, and perform an OR operation between the data in the shift storage unit VB1 and the data in the shift storage unit VB2 to obtain 4-bit processed data; use the processed data to replace the high 4 bits of the initialization scene control data in the scene control storage unit QB769 to obtain the final scene control data.

[0029] Wherein, W represents the simulated image information, c represents the thunderstorm weather information, d represents the rain turning to clear weather information, and e represents the windy weather information. The value of the windy weather information ranges from 0 to 2. When the value of the windy weather information is 0, it means that the simulated windy weather information is windless weather information; when the value of e is 1, the windy weather information is left-side windy weather information; and when the value of e is 2, the windy weather information is right-side windy weather information.

[0030] To address the aforementioned technical problems, this invention also provides a method for simulating power outage and restoration scenarios of pole-mounted transformers, the specific technical content of which is as follows:

[0040] Figure 3This is a flowchart illustrating a scenario simulation method for power outage and restoration of a pole-mounted transformer according to an embodiment of the present invention. Detailed Implementation

[0041] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0042] like Figure 1 As shown, this embodiment provides a simulation system for power outage and restoration operations of a pole-mounted transformer, including:

[0043] The host computer is used to generate simulation information for the power transmission scenario of the pole-mounted transformer.

[0044] The communication module, connected to the host computer, is used to receive the power transmission scenario simulation information and send the power transmission scenario simulation information to the outside.

[0045] The signal acquisition module is used to acquire simulated power transmission operation information of the pole-mounted transformer;

[0046] The MCU module, connected to the communication module and the signal acquisition module, is used to receive the power transmission scenario simulation information and generate simulated image information based on the power transmission scenario simulation information; it is also used to receive the power transmission operation simulation information and generate power transmission operation result information based on the power transmission operation simulation information.

[0047] The display screen, connected to the MCU module, is used to receive and display the analog image information and the power supply operation result information;

[0048] The power supply module, connected to the communication module, the signal acquisition module, the MCU module, and the display screen, is used to provide power to the signal acquisition module, the MCU module, and the display screen respectively.

[0049] like Figure 2 As shown, the power supply operation simulation information includes external point signals and external switch signals; the external switch signals include three-phase fuse signals and pole-mounted transformer load signals; wherein, the external point signals are the contact signals of the intermediate relay controlling the power supply operation of the pole-mounted transformer, and the three-phase fuse signals include the point signals of the fuses of the three phases of the pole-mounted transformer.

[0050] Specifically, the external point signal is 8-bit data;

[0051] The MCU module is specifically used to create an 8-bit scene control storage unit QB769 and initialize the data in the scene control storage unit QB769 to obtain initialized scene control data.

[0052] The MCU module is further configured to compare the external point signal with the initial scenario control data. If the external point signal matches the initial scenario control data, the simulated image information is generated based on the initial scenario control data. If the external point signal does not match the initial scenario control data, the initial scenario control data is updated based on the external point signal to obtain the final scenario control data, and the simulated image information is generated based on the final scenario control data. When controlling the HMI simulation screen, the current scenario is compared with the previous scenario. If they match, the update is abandoned; if they do not match, the latest state is updated, and the updated state is recorded as the previous state to avoid repeated updates of the output scenario.

[0053] When the external point signal is inconsistent with the initial scenario control data, the MCU module is further specifically used to create a 4-bit shift storage unit VB1 and a 4-bit shift storage unit VB2; the high 4 bits of the external point signal are stored in the shift storage unit VB1, the high 4 bits of the initial scenario control data are stored in the shift storage unit VB2, and the data in the shift storage unit VB1 and the data in the shift storage unit VB2 are ORed to obtain 4-bit processed data; the processed data is used to replace the high 4 bits of the initial scenario control data in the scenario control storage unit QB769 to obtain the final scenario control data. The OR operation between the data in VB1 and the data in VB2 ensures that the low 4 bits of the original storage unit QB769 remain unchanged, and the new simulated scenario state is output to the storage unit QB769 to control the required scenario dynamics.

[0054] In some embodiments, regarding the pole-mounted transformer, each of the three fuses is designed with a detection point. Each fuse is used to detect the fuse point at the upper and lower positions, respectively, where the upper and lower positions are the two contacts of the fuse. Additionally, there is a load switch on the low-voltage side after the transformer, and a load cabinet tag signal. The three-phase fuse signals include A-phase fuse signals, B-phase fuse signals, and C-phase fuse signals. The A-phase fuse signal includes the two contact signals of the A-phase fuse, the B-phase fuse signal includes the two contact signals of the B-phase fuse, and the C-phase fuse signal includes the two contact signals of the C-phase fuse.

[0055] The MCU module is specifically used to generate Boolean variable data based on the two contact signals of the A-phase fuse, the two contact signals of the B-phase fuse, and the two contact signals of the C-phase fuse, respectively, to obtain the structural data of the A-phase fuse, the B-phase fuse, and the C-phase fuse; and to generate the power supply operation result information based on the structural data of the A-phase fuse, the B-phase fuse, the C-phase fuse, and the load signal of the pole-mounted transformer.

[0056] The MCU module is also specifically used to generate Boolean variable data based on the load signal of the pole-mounted transformer to obtain Boolean load data; and to generate the simulated image information based on the structure data of the A-phase fuse, the structure data of the B-phase fuse, the structure data of the C-phase fuse, and the Boolean load data.

[0057] The Boolean load data includes load switch data and cabinet tag data; the Boolean load data is represented as {a, b}, the A-phase fuse structure data is represented as {m, n}, the B-phase fuse structure data is represented as {i, j}, and the C-phase fuse structure data is represented as {x, y}; where a represents the load switch data, b represents the cabinet tag data, m and n represent the voltage data of the two contacts of the A-phase fuse, i and j represent the voltage data of the two contacts of the B-phase fuse, and x and y represent the voltage data of the two contacts of the C-phase fuse.

[0058] As Boolean variables are used as inputs, True: "1" and False: "0" are used for convenient calculation. Therefore, the phase fuse data structure A = {m, n} is defined, where m is the upper position signal of the fuse detection and n is the lower position signal of the fuse detection. For example, A = {0, 1} indicates that the upper position of phase A fuse has been pulled down, but it is still hanging on the fuse bracket. According to the above definition, the three-phase fuse status can be obtained as a two-dimensional array, ABC = {{m, n}, {i, j}, {x, y}}, and the Boolean load data is defined as S = {a, b}.

[0059] An example of the actual detection signal results is: ABC = {{0, 0}, {0, 1}{1, 1}}, which means that the fuse of phase A has been removed, the upper end of the fuse of phase B has been pulled down, while the lower end is still on the bracket, and the fuse of phase C is completely on the bracket; at the same time, S is used to represent the load switch data and cabinet tag data, such as S = {1, 0}, which means that the load switch is in the closed position and there is no tag signal.

[0060] Under normal operating conditions, the pole-mounted transformer is in operation, and the low-voltage side load is powered normally. The corresponding collected data is ABC = {{1, 1}, {1, 1}, S = {1, 0}. When the pole-mounted transformer has been de-energized and the low-voltage side power supply is disconnected, the corresponding collected data is ABC = {{0, 0}, {0, 0}, S = {0, 1}.

[0061] Specifically, the simulated image information includes thunderstorm weather information, rain turning to clear weather information, and windy weather information;

[0062] The MCU module is specifically used to randomly generate thunderstorm weather information and / or rain-to-sunset weather information and / or windy weather information based on the power transmission scenario simulation information or power transmission operation simulation information; wherein, the windy weather information is left-windy weather information, right-windy weather information, or windless weather information;

[0063] The display screen is specifically used to receive and display the thunderstorm weather information and / or the rain turning to clear weather information and / or the left-side windy weather information and / or the windy weather information.

[0064] The simulated image information is represented as follows:

[0065] W = {c, d, e};

[0066] Wherein, W represents the simulated image information; c represents the thunderstorm weather information, with a value ranging from 0 to 10 in seconds, where a value of 0 indicates no thunderstorm effect; d represents the rain-to-sunset weather information, with a value ranging from 1 to 5 in seconds; e represents the windy weather information, with a value ranging from 0 to 2, where a value of 0 indicates calm weather; a value of 1 indicates left-side wind; and a value of 2 indicates right-side wind. For example, generating weather effect data as W = {5, 2, 1} indicates that the scene effect will be transformed into a thunderstorm weather lasting 5 seconds, followed by a 2-second rain-to-sunset animation, then switching to left-side wind. The left-side wind effect will continue until the operation is completed or the operation times out.

[0067] Based on practice and assessment requirements, a power outage operation was performed on a 10kV pole-mounted transformer, and random weather effect data W = {X, 2, 2} was generated. The pole-mounted transformer was in operation, and the low-voltage side load was powered normally, with the corresponding collected data being ABC = {{1, 1}, {1, 1}{1, 1}}, and S = {1, 0}. During the operation, the scenario was a thunderstorm lasting for X seconds, followed by a 2-second animation of rain turning to clear skies, and then switching to a right-wind-sweeping pattern. According to the operating specifications for outdoor 10kV pole-mounted transformers, no operation is allowed during thunderstorms. The system collected signals throughout the entire process. Within X+2 seconds, the detected signals needed to remain at ABC = {{1, 1}, {1, 1}{1, 1}}, and S = {1, 0}. If an operation occurred, the detected signals would change, the system would issue an illegal operation error, and send the illegal operation data to the host computer via USB or network.

[0068] This invention utilizes a host computer to generate weather simulation information, a signal acquisition module to collect actual operation information of the pole-mounted transformer, and a display screen to show the weather simulation information and actual operation information. The display screen can intuitively show the actual operation scenarios of power outage and power restoration of the pole-mounted transformer under different weather conditions, making it easier for assessors to give evaluation conclusions intuitively based on the display results.

[0069] like Figure 3 As shown, this embodiment of the invention provides a method for simulating power outage and restoration scenarios of a pole-mounted transformer, comprising the following steps:

[0070] S1. Use the host computer to generate simulation information of the power transmission scenario of the pole-mounted transformer.

[0071] S2. Receive the power transmission scenario simulation information using the communication module connected to the host computer, and send the power transmission scenario simulation information outward;

[0072] S3. Use the signal acquisition module to collect the power supply operation simulation information of the pole-mounted transformer;

[0073] S4. Receive the power transmission scenario simulation information using the MCU module connected to the communication module and the signal acquisition module, and generate simulated image information based on the power transmission scenario simulation information;

[0074] S5. Receive the power supply operation simulation information using the MCU module connected to the signal acquisition module, and generate power supply operation result information based on the power supply operation simulation information;

[0075] S6. Receive and display the analog image information and the power supply operation result information using the display screen connected to the MCU module; wherein, the power supply module is connected to the communication module, the signal acquisition module, the MCU module and the display screen, and the power supply module provides power to the signal acquisition module, the MCU module and the display screen respectively.

[0076] The data format for the power transmission operation results is as follows:

[0077] ABC = {{1, 1}, {1, 1}, S = {1, 0}, the acquired signals are #ABC = {{#m, #n}, {#i, #j}, {#x, #y}}, #S = {#a, #b}, and the calculation method is as follows:

[0078] R=((ABC&#ABC)(S&#S))&((ABC|#ABC)(S|#S));

[0079] R represents the actual power transmission operation result information collected. That is, by comparing the power transmission operation result information with the preset power transmission information, it can be determined whether the collected data of whether the action has occurred or not is the correct answer.

[0080] Therefore, the correct operating procedure is to maintain the accepted signals as #ABC={{1,1},{1,1},{1,1}},#S={1,0} within X+2 seconds; #ABC and #S represent the standard data of the power transmission operation result information, namely the above-mentioned preset power transmission information.

[0081] The signal indicating a successful power outage operation, i.e., the preset power-on information, is as follows:

[0082] 1.T<(X+2)#ABC={{1,1}, {1,1}, {1,1}}, #S={1,0};

[0083] 2.T>(X+2)#ABC={{1,1},{0,1},{1,1}}, #S={1,0};

[0084] 3.T>(X+2)#ABC={{1,1},{0,0},{1,1}}, #S={1,0};

[0085] 4.T>(X+2)#ABC={{1,1},{0,0},{0,1}}, #S={1,0};

[0086] 5.T>(X+2)#ABC={{1,1},{0,0},{0,0}}, #S={1,0};

[0087] 6.T>(X+2)#ABC={{0,1},{0,0},{0,0}}, #S={1,0};

[0088] 7.T>(X+2)#ABC={{0,0}, {0,0}, {0,0}}, #S={1,0};

[0089] 8.T>(X+2)#ABC={{0,0},{0,0},{0,0}}, #S={0,0};

[0090] 9.T>(X+2)#ABC={{0,0},{0,0},{0,0}}, #S={0,1};

[0091] In the above operation steps, the signal between any two steps is calculated using a formula; if the result is false, it is considered an illegal operation. The system requires that all signals be reset. During the reset process, the signals accepted do not need to be calculated using the formula until the signals return to their initial state.

[0092] The correct signal sequence for power-on operation is as follows:

[0093] 1.T<(X+2)#ABC={{0,0}, {0,0}, {0,0}}, #S={0,1};

[0094] 2.T>(X+2)#ABC={{0,0},{0,1},{0,0}}, #S={0,1};

[0095] 3.T>(X+2)#ABC={{0,0},{1,1},{0,0}}, #S={0,1};

[0096] 4.T>(X+2)#ABC={{0,0},{1,1},{0,1}}, #S={0,1};

[0097] 5.T>(X+2)#ABC={{0,0},{1,1},{1,1}}, #S={0,1};

[0098] 6.T>(X+2)#ABC={{0,1},{1,1},{1,1}}, #S={0,1};

[0099] 7.T>(X+2)#ABC={{1,1},{1,1},{1,1}}, #S={0,1};

[0100] 8.T>(X+2)#ABC={{1,1},{1,1},{1,1}}, #S={0,0};

[0101] 9.T>(X+2)#ABC={{1,1},{1,1},{1,1}}, #S={1,0};

[0102] Similarly, in the above operation steps, the signal between any two steps is calculated using a formula; if the result is incorrect, it is an illegal operation. The system requires all signals to be reset. During the reset process, the accepted signals do not need to be calculated using formulas until the signals return to their initial state. The MCU module compares the power supply operation result information obtained at each step of the pole-mounted transformer's power supply operation with the preset power supply information corresponding to each step to obtain operation judgment information. When the power supply operation result information obtained at each step matches the preset power supply information corresponding to each step, the operation judgment information is qualified; when the power supply operation result information obtained at each step does not match the preset power supply information corresponding to each step, the operation judgment information is unqualified. The display screen shows the operation judgment information and the power supply operation result information obtained at each step. Specifically, the comparison is made between external point signals and preset point signals, and between external switch signals and preset switch signals. By digitizing each power supply operation step, the data can be analyzed and displayed to intuitively show whether the operation of each step or node of the power supply operator in the process of powering the pole-mounted transformer is qualified. This makes the operation assessment more intuitive and improves the objectivity and accuracy of the evaluation.

[0103] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the concept and principles of the present invention should be included within the protection scope of the present invention.
