Technical Field
[0001] This application relates to the field of power distribution room technology, and in particular to a power distribution room control method, system and storage medium based on digital twin. Background Technology
[0002] A substation is an indoor integrated system in a power supply system used to step down high voltage to the voltage level required by users through transformers. It integrates protection, metering, and distribution functions and typically includes power transformers, high-voltage distribution cabinets, low-voltage distribution cabinets, cables, etc. A substation is a line connection point in a power grid, a facility used to transform voltage, exchange power, and collect and distribute electrical energy. Substations are an important component of the power grid and a crucial link in power transmission, playing a vital role in ensuring the safe and economical operation of the power grid. Therefore, ensuring the normal operation of substations is of paramount importance.
[0003] In related technologies, manual periodic inspections are usually used to check whether the operating parameters of power equipment are normal. However, manual periodic inspections cannot monitor the operating parameters of the equipment in real time. When a fault occurs in the power equipment during the intervals between manual inspections, it is not easy for staff to detect and deal with the fault in time, which can easily lead to safety accidents. Summary of the Invention
[0004] To enhance the monitoring of current operating parameters of power equipment and help staff to promptly identify and handle faults, this application provides a digital twin-based substation control method, system, terminal, and storage medium.
[0005] The first aspect of this application provides a control method for substations based on digital twins, which adopts the following technical solution: A digital twin-based substation control method includes: Obtain the current operating parameters of the power equipment; Map the current operating parameters to a preset digital twin model; Based on the digital twin model, determine whether the current operating parameters meet the preset parameter thresholds; If the current operating parameters do not meet the parameter threshold, then abnormal parameters are obtained; Based on the aforementioned abnormal parameters, a target processing plan is generated.
[0006] By adopting the above technical solution, a connection is established between the substation and a pre-set digital twin model, and the current operating parameters of the power equipment are mapped onto the digital twin model. By determining whether the current operating parameters mapped onto the digital twin model meet the parameter thresholds, it is possible to determine whether the current operating parameters of each power device in the substation meet the parameter thresholds. When the current operating parameters do not meet the parameter thresholds, abnormal parameters are acquired, and a target handling plan is generated based on the abnormal parameters. Through the digital twin model, real-time monitoring of the current operating parameters is achieved, which not only helps reduce the possibility of sudden failures but also helps remind staff to detect and handle faults in a timely manner, thereby reducing the possibility of safety accidents. At the same time, the development of target handling plans based on abnormal parameters allows for more reasonable equipment maintenance plans, eliminating the need for repetitive periodic inspections and thus helping to reduce equipment operation and maintenance costs.
[0007] Optionally, the specific steps for generating the target processing scheme based on the anomaly parameters include: Based on the aforementioned abnormal parameters, the abnormality level is obtained; Determine whether the abnormality level exceeds a preset level threshold; If the anomaly level exceeds the level threshold, an alarm will be triggered; If the anomaly level does not exceed the level threshold, an early warning is issued, and the operating parameters are adjusted.
[0008] By adopting the above technical solution, the anomaly level is obtained, and the severity of the anomaly is determined by whether the anomaly level exceeds the level threshold. When the anomaly level exceeds the level threshold, it indicates that the anomaly is of high severity and the system can no longer adjust automatically. Therefore, an alarm is directly issued to notify the staff to repair the equipment in a timely manner. When the anomaly level does not exceed the level threshold, it indicates that the anomaly is of low severity, and the system can self-adjust by automatically adjusting the current operating parameters. Therefore, adjusting the operating parameters while issuing an early warning helps the staff to further understand the actual situation of the power equipment based on the anomaly level, thereby helping to make corresponding target handling plans in a timely manner based on the actual situation.
[0009] Optionally, the current operating parameters include the current output voltage; the specific steps for issuing an early warning and adjusting the operating parameters if the anomaly level does not exceed the level threshold include: If the abnormality level does not exceed the level threshold, then determine whether the current output voltage exceeds a preset first voltage threshold. If the current output voltage does not exceed the first voltage threshold, then obtain the first absolute difference between the current output voltage and the first voltage threshold; An early warning is issued based on the first absolute difference, and the current output voltage is increased.
[0010] By adopting the above technical solution, when the abnormality level does not exceed the level threshold, it is then determined whether the current output voltage exceeds the preset first voltage threshold. If the current output voltage does not exceed the voltage threshold, but the current operating parameters do not meet the parameter threshold, it indicates that the current output voltage is too low. The first absolute difference between the current output voltage and the voltage threshold is calculated, and an early warning is issued based on the first absolute difference. The current output voltage is then increased based on the absolute difference, which helps to ensure that the current output voltage is kept within the allowable range. This helps to ensure the normal and safe use of electricity by the power terminal and helps to prevent damage to the power terminal due to the current output voltage being too low.
[0011] Optional, also includes: If the current output voltage exceeds the first voltage threshold, then obtain the current time node; Determine if the current time point is a special date; If the current time point is the special date, then obtain the usage type of the substation; Determine whether the usage type is industrial. If the usage type is not the industrial type, then obtain the real-time voltage; Determine whether the real-time voltage meets the preset second voltage threshold; If the real-time voltage does not meet the second voltage threshold, the current output voltage is adjusted based on the real-time voltage.
[0012] By adopting the above technical solution, when the current output voltage exceeds the voltage threshold, it indicates that the current output voltage is too high and there is a certain risk. First, it is determined whether the current time node is a special date. If the current time node is a special date, it is then determined whether the usage type of the substation is industrial. If the usage type is not industrial, the real-time voltage is obtained, and it is determined whether the real-time voltage meets the preset second voltage threshold. If the real-time voltage does not meet the second voltage threshold, the current output voltage is adjusted based on the real-time voltage. When the current time node is a special date, the power consumption of the electrical terminal will increase, which may easily lead to a lower voltage at the electrical terminal. Therefore, a slightly high current output voltage is normal and no alarm measures are required. When the real-time voltage does not meet the second voltage threshold, the real-time voltage is either too high or too low. Therefore, adjusting the current output voltage in reverse based on the real-time voltage helps the electrical terminal to use electricity normally and safely on special dates, preventing damage to the electrical terminal due to excessively high or low current output voltage.
[0013] Optional, also includes: If the current time point is not the specific date, then obtain the target geographical location; Based on the target geographical location, obtain the target temperature; Determine whether the target temperature meets a preset temperature threshold; If the target temperature meets the temperature threshold, then determine whether the current time point is a peak electricity consumption period; If the current time point is not the peak electricity consumption period, then obtain the first absolute difference; A warning is issued based on the first absolute difference, and the current output voltage is reduced.
[0014] By adopting the above technical solution, when the current time node is not a special date, the target geographical location is obtained, and the target temperature is obtained based on the target geographical location. It is then determined whether the target temperature meets the preset temperature threshold. When the target temperature meets the temperature threshold, it indicates that the target temperature is within a suitable temperature range and there is no need to use additional electrical terminals such as air conditioners. It is also determined whether the current time node is a peak electricity consumption period. If the current time node is not a peak electricity consumption period, the first absolute difference is obtained. Therefore, when the current output voltage exceeds the first voltage threshold, an early warning is issued based on the first absolute difference, and the current output voltage is lowered. This helps to save energy and also helps to prevent damage to electrical terminals caused by excessively high or low current output voltage.
[0015] Optional, also includes: If the current time point is the peak electricity consumption period, then the first historical output voltage is obtained; Obtain the second difference between the current output voltage and the first historical output voltage; Based on the first historical output voltage and the second difference, the current output voltage is increased.
[0016] By adopting the above technical solution, when the current time node is the peak electricity consumption period, the electricity consumption is large, so the voltage at the power terminal will drop. Therefore, it is necessary to increase the current output voltage to increase the voltage at the power terminal. So the current output voltage is slightly higher than normal, which is within the safe range. The first historical output voltage is obtained, and the actual current voltage demand is inferred based on the first historical output voltage. The second difference between the current output voltage and the first historical output voltage is obtained. Based on the second difference, the current output voltage is increased. Adjusting the current output voltage according to the actual current voltage demand helps to reduce energy waste while maintaining normal and safe electricity use at the power terminal.
[0017] Optional, optional: If the target temperature does not meet the temperature threshold, then a second historical output voltage is obtained based on the target temperature; Obtain historical and current electricity consumption data; Based on the historical and current electricity consumption data, electricity consumption trends are obtained; The current output voltage is adjusted based on the second historical output voltage and the power consumption trend.
[0018] By adopting the above technical solution, if the target temperature does not meet the temperature threshold, it indicates that the target temperature has exceeded the suitable temperature. Then, the second historical output voltage is obtained based on the target temperature, and the power consumption trend is obtained. The power consumption situation is inferred based on the second historical output voltage and the power consumption trend. Then, the current output voltage is adjusted according to the power consumption situation, which helps to reduce energy waste while maintaining normal and safe power consumption of the power terminal.
[0019] Secondly, this application also discloses a substation control system based on digital twins, which adopts the following technical solution: A digital twin-based substation control system includes: The first acquisition module is used to acquire the current operating parameters of the power equipment; The mapping module is used to map the current operating parameters to a preset digital twin model; The judgment module is used to determine whether the current operating parameters meet the preset parameter threshold based on the digital twin model; If the current operating parameters do not meet the parameter threshold, the second acquisition module is used to acquire abnormal parameters. The processing module is used to generate a target processing solution based on the abnormal parameters.
[0020] By adopting the above technical solution, a connection is established between the substation and a pre-set digital twin model, and the current operating parameters of the power equipment are mapped onto the digital twin model. By determining whether the current operating parameters mapped onto the digital twin model meet the parameter thresholds, it is possible to determine whether the current operating parameters of each power device in the substation meet the parameter thresholds. When the current operating parameters do not meet the parameter thresholds, abnormal parameters are acquired, and a target handling plan is generated based on the abnormal parameters. Through the digital twin model, real-time monitoring of the current operating parameters is achieved, which not only helps reduce the possibility of sudden failures but also helps remind staff to detect and handle faults in a timely manner, thereby reducing the possibility of safety accidents. At the same time, the development of target handling plans based on abnormal parameters allows for more reasonable equipment maintenance plans, eliminating the need for repetitive periodic inspections and thus helping to reduce equipment operation and maintenance costs.
[0021] Thirdly, this application provides a computer-readable storage medium that adopts the following technical solution: A computer-readable storage medium storing a computer program that, when loaded by a processor, executes the method of the first aspect.
[0022] By adopting the above technical solution, a computer program is generated based on the method of the first aspect and stored in a computer-readable storage medium for loading and execution by a processor. The computer-readable storage medium facilitates the reading and storage of the computer program.
[0023] In summary, this application includes the following beneficial technical effects: By linking the substation with a pre-defined digital twin model and mapping the current operating parameters of the power equipment onto the digital twin model, the system can determine whether the current operating parameters of each power device in the substation meet the parameter thresholds. When the current operating parameters do not meet the thresholds, abnormal parameters are identified, and a target handling plan is generated based on these abnormal parameters. Through the digital twin model, real-time monitoring of the current operating parameters is achieved. This not only helps reduce the possibility of sudden failures but also helps remind staff to detect and handle faults in a timely manner, thereby reducing the possibility of safety accidents. At the same time, developing target handling plans based on abnormal parameters allows for more rational equipment maintenance plans, eliminating the need for repetitive periodic inspections and thus helping to reduce equipment operation and maintenance costs.

[0026] In the first aspect, this application discloses a control method for substations based on digital twins.
[0027] Reference Figure 1 A digital twin-based substation control method includes steps S101 to S105: Step S101: Obtain the current operating parameters of the power equipment.
[0028] Specifically, in this embodiment, the power equipment refers to the power equipment in the substation, such as distribution cabinets and switch cabinets; the current operating parameters include voltage parameters, current parameters, and power parameters; in this embodiment, the corresponding current operating parameters can be detected by voltage sensors and current sensors, for example, voltage sensors are used to detect voltage parameters, and current sensors are used to detect current parameters.
[0029] Step S102: Map the current running parameters to the preset digital twin model.
[0030] Specifically, in this embodiment, Digital Twin is a simulation process that fully utilizes data such as physical models, sensor updates, and operational history to integrate multiple disciplines, multiple physical quantities, multiple scales, and multiple probabilities, and completes mapping in virtual space to reflect the entire life cycle of the corresponding physical equipment.
[0031] Step S103: Based on the digital twin model, determine whether the current operating parameters meet the preset parameter thresholds.
[0032] Specifically, in this embodiment, the parameter threshold is set according to different operating parameters, including voltage threshold and current threshold, and the parameter threshold is a threshold range composed of the maximum threshold and the minimum threshold.
[0033] Step S104: If the current running parameters do not meet the parameter threshold, then obtain the abnormal parameters.
[0034] Specifically, in this embodiment, abnormal parameters are current operating parameters that do not meet the parameter threshold. For example, if the voltage parameter of the distribution cabinet does not meet the parameter threshold, then the abnormal parameter is the voltage parameter.
[0035] Step S105: Generate the target processing plan based on the abnormal parameters.
[0036] Specifically, in this embodiment, the target processing scheme is the processing scheme formulated for different abnormal parameters.
[0037] The digital twin-based substation control method provided in this embodiment establishes a connection between the substation and a preset digital twin model, and maps the current operating parameters of the power equipment into the digital twin model. By determining whether the current operating parameters mapped to the digital twin model meet the parameter thresholds, it can be determined whether the current operating parameters of each power device in the substation meet the parameter thresholds. When the current operating parameters do not meet the parameter thresholds, abnormal parameters are acquired, and a target handling plan is generated based on the abnormal parameters. Through the digital twin model, real-time monitoring of the current operating parameters is achieved, which not only helps reduce the possibility of sudden failures but also helps remind staff to detect and handle faults in a timely manner, thereby reducing the possibility of safety accidents. At the same time, the target handling plan based on abnormal parameters allows for more reasonable equipment maintenance planning, eliminating the need for repetitive periodic inspections and thus helping to reduce equipment operation and maintenance costs.
[0038] Reference Figure 2 In one embodiment of this example, if the current running parameters do not meet the parameter threshold in step S104, the specific steps for obtaining the abnormal parameters include steps S201 to S204: Step S201: Obtain the anomaly level based on the anomaly parameters.
[0039] Specifically, in this embodiment, the anomaly level, i.e. the level of the abnormal parameter, can be set to level one, level two, and level three. For example, when the parameter value of the abnormal parameter is greater than 150% of the maximum parameter threshold, or less than 50% of the minimum parameter threshold, the anomaly level is level three; when the parameter value of the abnormal parameter is between 120% and 150% of the maximum parameter threshold, or between 50% and 80% of the minimum parameter threshold, the anomaly level is level two; when the parameter value of the abnormal parameter is between 100% and 120% of the maximum parameter threshold, or between 80% and 100% of the minimum parameter threshold, the anomaly level is level one.
[0040] Step S202: Determine whether the abnormality level exceeds the preset level threshold.
[0041] Specifically, in this embodiment, the level threshold can be level two.
[0042] Step S203: If the abnormality level exceeds the level threshold, an alarm will be triggered.
[0043] Specifically, in this embodiment, the alarm content includes the specific cabinet and specific parameters. For example, the abnormality level of the voltage parameter of the power distribution cabinet is level three. When the abnormality level is level three, it indicates that level one cannot resolve the abnormality by adjusting the current operating parameters by the control system itself.
[0044] Step S204: If the anomaly level does not exceed the level threshold, issue an early warning and adjust the operating parameters.
[0045] Specifically, in this embodiment, adjusting the operating parameters can be done by the control system itself. For example, if the voltage parameter value is too high, the control system will automatically reduce the voltage parameter value.
[0046] The digital twin-based substation control method provided in this embodiment acquires the anomaly level and then determines the severity of the anomaly by judging whether the anomaly level exceeds a level threshold. When the anomaly level exceeds the level threshold, it indicates that the anomaly is of high severity and the system can no longer automatically adjust. Therefore, an alarm is directly issued to notify the staff to repair the equipment in a timely manner. When the anomaly level does not exceed the level threshold, it indicates that the anomaly is of low severity and the system can automatically adjust the current operating parameters to self-adjust. Therefore, adjusting the operating parameters while issuing an early warning helps the staff to further understand the actual situation of the power equipment based on the anomaly level, thereby helping to make corresponding target handling solutions in a timely manner based on the actual situation.
[0047] Reference Figure 3 In one embodiment of this example, if the abnormality level in step S204 does not exceed the level threshold, then an early warning is issued, and the operating parameters are adjusted. The specific steps include steps S301 to S303: Step S301: If the abnormality level does not exceed the level threshold, then determine whether the current output voltage exceeds the preset first voltage threshold.
[0048] Specifically, in this embodiment, the current operating parameters include the current output voltage, and may also include the current output current, etc. This embodiment uses the current output voltage of the distribution cabinet as a specific example.
[0049] Step S302: If the current output voltage does not exceed the first voltage threshold, then obtain the first absolute difference between the current output voltage and the first voltage threshold.
[0050] Specifically, in this embodiment, the first absolute difference = |current output voltage - first voltage threshold|, where the first voltage threshold is the voltage range allowed when the distribution cabinet is operating normally, and can be set according to the actual situation, for example, it can be set to [220,250]V or [380,420]V, etc.
[0051] Step S303: Issue a warning based on the first absolute difference and increase the current output voltage.
[0052] Specifically, in this embodiment, the current output voltage is increased by a corresponding value based on the value of the first absolute difference. For example, when the first absolute difference is [20,50]V, the current output voltage is increased by A*[20,50]V, where A is a constant coefficient.
[0053] The digital twin-based substation control method provided in this embodiment determines whether the current output voltage exceeds a preset first voltage threshold when the abnormality level does not exceed the level threshold. If the current output voltage does not exceed the voltage threshold, but the current operating parameters do not meet the parameter threshold, it indicates that the current output voltage is too low. The first absolute difference between the current output voltage and the voltage threshold is calculated, and an early warning is issued based on the first absolute difference. The current output voltage is then increased based on the absolute difference, which helps to ensure that the current output voltage is kept within the allowable range, thereby helping to ensure normal and safe power consumption of the electrical terminals and preventing damage to the electrical terminals due to the current output voltage being too low.
[0054] Reference Figure 4 In one embodiment of this example, steps S401 to S407 are further included: Step S401: If the current output voltage exceeds the first voltage threshold, then obtain the current time node.
[0055] Specifically, in this embodiment, the current time node refers to the current specific time, such as October 1, 2022.
[0056] Step S402: Determine whether the current time node is a special date.
[0057] Specifically, in this embodiment, special dates refer to dates with higher electricity consumption, such as the Spring Festival and the Lantern Festival, when electricity consumption is much higher than on ordinary days.
[0058] Step S403: If the current time node is a special date, obtain the usage type of the substation.
[0059] Specifically, in this embodiment, the types of use of the substation include civil and industrial types.
[0060] Step S404: Determine whether the usage type is industrial.
[0061] Specifically, in this embodiment, industrial type refers to a power distribution room used for power distribution to factories, etc.
[0062] Step S405: If the type used is not industrial, obtain the real-time voltage.
[0063] Specifically, in this embodiment, real-time voltage refers to the real-time voltage of the factory's power terminal, which can be obtained through a voltage sensor and sent to the digital twin model via a network.
[0064] Step S406: Determine whether the real-time voltage meets the preset second voltage threshold.
[0065] Specifically, in this embodiment, the second voltage threshold refers to the voltage range that the real-time voltage is allowed to be set. It can be set according to the rated voltage of the power terminal. For example, if the rated voltage of the power terminal is 220V, then the second voltage threshold can be set to [210, 230]V.
[0066] Step S407: If the real-time voltage does not meet the second voltage threshold, adjust the current output voltage based on the real-time voltage.
[0067] Specifically, in this embodiment, the difference between the real-time voltage and the second voltage threshold can be calculated first, that is, the difference obtained by subtracting the second voltage threshold from the real-time voltage. Then, the amount of voltage to be adjusted is calculated based on the ratio of the current output voltage to the real-time voltage. For example, when the current output voltage is 240V and the real-time voltage is 220V, then when the real-time voltage is 200V, the current output voltage is 240 / 220*200=218V. Then, 240 is subtracted from 218 to obtain the final voltage value to be adjusted. It is worth noting that in this embodiment, it is assumed that the power terminal remains consistent or changes are negligible.
[0068] The digital twin-based substation control method provided in this embodiment indicates that the current output voltage is too high and poses a certain risk when it exceeds a voltage threshold. First, it determines whether the current time is a special date. If it is, it then determines whether the substation's usage type is industrial. If not, it acquires the real-time voltage and determines whether it meets a preset second voltage threshold. If the real-time voltage does not meet the second voltage threshold, it adjusts the current output voltage based on the real-time voltage. When the current time is a special date, the power consumption of the electrical terminals will increase, which may easily lead to lower voltage at the terminals. Therefore, a high current output voltage is normal and no alarm measures are needed. When the real-time voltage does not meet the second voltage threshold, the real-time voltage is either too high or too low. Therefore, adjusting the current output voltage in reverse based on the real-time voltage helps ensure normal and safe power consumption for the electrical terminals on special dates, preventing damage to the terminals due to excessively high or low current output voltage.
[0069] Reference Figure 5 In one embodiment of this example, steps S501 to S506 are further included: Step S501: If the current time node is not a special date, obtain the target geographical location.
[0070] Specifically, in this embodiment, the target geographical location refers to the city or county where the substation is located. For example, if the substation is located in Kaifu District of Changsha City, then the target geographical location can be Changsha City or Kaifu District of Changsha City.
[0071] Step S502: Obtain the target temperature based on the target geographical location.
[0072] Specifically, in this embodiment, the target temperature refers to the temperature at the target geographical location.
[0073] Step S503: Determine whether the target temperature meets the preset temperature threshold.
[0074] Specifically, in this embodiment, the temperature threshold can be set according to the temperature that the human body feels comfortable, for example, [15, 26]℃.
[0075] Step S504: If the target temperature meets the temperature threshold, determine whether the current time point is a peak electricity consumption period.
[0076] Specifically, in this embodiment, the peak electricity consumption period can be set according to different target geographical locations. For example, the peak electricity consumption period in Changsha is from 7 pm to 10 pm.
[0077] Step S505: If the current time point is not a peak electricity consumption period, then obtain the first absolute difference.
[0078] Step S506: Issue a warning based on the first absolute difference and lower the current output voltage.
[0079] Specifically, in this embodiment, the first absolute difference in this step is the same as the first absolute difference in step S303. Based on the value of the first absolute difference, the current output voltage is increased by the corresponding value. For example, when the first absolute difference is [20,50]V, the current output voltage is decreased by A*[20,50]V, where A is a constant coefficient.
[0080] The digital twin-based substation control method provided in this embodiment obtains the target geographical location and the target temperature based on the target geographical location when the current time node is not a special date. It then determines whether the target temperature meets a preset temperature threshold. If the target temperature meets the temperature threshold, it indicates that the target temperature is within a suitable temperature range and no additional electrical terminals such as air conditioners are needed. The method also determines whether the current time node is a peak electricity consumption period. If the current time node is not a peak electricity consumption period, it obtains a first absolute difference. Therefore, when the current output voltage exceeds the first voltage threshold, an early warning is issued based on the first absolute difference, and the current output voltage is lowered. This helps save energy and also helps prevent damage to electrical terminals caused by excessively high or low current output voltage.
[0081] Reference Figure 6In one embodiment of this example, steps S601 to S603 are further included: Step S601: If the current time point is a peak electricity consumption period, then obtain the first historical output voltage.
[0082] Specifically, in this embodiment, the first historical output voltage is the average output voltage during peak electricity consumption periods over a certain period of time in the past. For example, if the average output voltage during peak electricity consumption periods over the past week is 240V, then the first historical output voltage is 240V. In this embodiment, the first output voltage is used as the output voltage during peak electricity consumption periods.
[0083] Step S602: Obtain the second difference between the current output voltage and the first historical output voltage.
[0084] Specifically, in this embodiment, the second difference = current output voltage - first historical output voltage.
[0085] Step S603: Based on the first historical output voltage and the second difference, increase the current output voltage.
[0086] Specifically, in this embodiment, the current output voltage is increased by a corresponding value based on the second difference. For example, when the second difference is [20,50]V, the current output voltage is decreased by A*[20,50]V, where A is a constant coefficient.
[0087] The digital twin-based substation control method provided in this embodiment addresses the issue that during peak electricity consumption periods, the voltage at the power terminals decreases due to higher electricity demand. Therefore, it is necessary to increase the current output voltage to raise the voltage at the power terminals. Since the current output voltage is slightly higher than expected, it is within a safe range. The method obtains a first historical output voltage and infers the actual current voltage demand based on it. It then obtains a second difference between the current output voltage and the first historical output voltage, and adjusts the current output voltage accordingly. This adjustment helps reduce energy waste while maintaining normal and safe electricity use at the power terminals.
[0088] Reference Figure 7 In one embodiment of this example, step S504 specifically includes steps S701 to S704: Step S701: If the target temperature does not meet the temperature threshold, then obtain the second historical output voltage based on the target temperature.
[0089] Specifically, in this embodiment, the second historical output voltage refers to the average output voltage over a certain period of time when the target temperature does not meet the temperature threshold. For example, if the average output voltage over the past week when the target temperature does not meet the temperature threshold is 230V, then the second historical output voltage is 230V. In this embodiment, the second output voltage is used as the output voltage when the target temperature does not meet the temperature threshold. When the target temperature does not meet the temperature threshold, it indicates that the target temperature is too high or too low, so the user needs to use equipment such as air conditioners or stoves, which leads to a decrease in real-time voltage.
[0090] Step S702: Obtain historical electricity consumption and current electricity consumption.
[0091] Specifically, in this embodiment, historical electricity consumption includes the number of historical electricity terminals and the user's historical electricity consumption habits, while current electricity consumption includes the number of current electricity terminals and the user's current electricity consumption habits.
[0092] Step S703: Obtain electricity consumption trends based on historical and current electricity consumption data.
[0093] Specifically, in this embodiment, the electricity consumption trend can be obtained based on changes in historical and current electricity consumption.
[0094] Step S704: Adjust the current output voltage based on the second historical output voltage and power consumption trend.
[0095] Specifically, in this embodiment, for example, the second historical output voltage is 230V, the number of historical power terminals is 10, and the user's historical power consumption habit is to use the air conditioner when the target temperature is above 28 degrees or below 12 degrees. The current number of power terminals is 5, and the user's historical power consumption habit is to use the air conditioner when the target temperature is above 30 degrees or below 10 degrees. It can be inferred that the power consumption trend is decreasing. Therefore, the current output voltage can be appropriately reduced compared to the past. The specific adjustment range can be calculated by establishing a function based on the second historical output voltage, historical power consumption, and current power consumption.
[0096] The digital twin-based substation control method provided in this embodiment indicates that if the target temperature does not meet the temperature threshold, it means that the target temperature has exceeded the suitable temperature. Then, the second historical output voltage is obtained based on the target temperature, and the power consumption trend is obtained. The power consumption situation is inferred based on the second historical output voltage and the power consumption trend. Then, the current output voltage is adjusted according to the power consumption situation. This helps to reduce energy waste while maintaining normal and safe power consumption of the power terminals.
[0097] The implementation principle of a digital twin-based substation control method in this application is as follows: obtain the current operating parameters of the power equipment, map the current operating parameters to a preset digital twin model, determine whether the current operating parameters meet the preset parameter thresholds based on the digital twin model, if the current operating parameters do not meet the parameter thresholds, obtain abnormal parameters, and generate a target processing scheme based on the abnormal parameters.
[0098] Secondly, this application also discloses a substation control system based on digital twins.
[0099] Reference Figure 8 A digital twin-based substation control system includes: The first acquisition module 1 is used to acquire the current operating parameters of the power equipment; Mapping module 2 is used to map the current running parameters to a preset digital twin model; Judgment module 3 is used to determine whether the current operating parameters meet the preset parameter thresholds based on the digital twin model; If the current running parameters do not meet the parameter threshold, the second acquisition module 4 is used to acquire abnormal parameters. Processing module 5 is used to generate a target processing plan based on abnormal parameters.
[0100] The implementation principle of a digital twin-based substation control system according to an embodiment of this application is as follows: The first acquisition module 1 acquires the current operating parameters of the power equipment and sends the current operating parameters to the mapping module 2. The mapping module 2 maps the current operating parameters to a preset digital twin model and sends the current operating parameters to the judgment module 3. The judgment module 3 judges whether the current operating parameters meet the preset parameter threshold based on the digital twin model. If the current operating parameters do not meet the parameter threshold, the judgment module 3 sends the judgment result to the second acquisition module 4. The second acquisition module 4 acquires abnormal parameters and sends the abnormal parameters to the processing module 5. The processing module 5 generates a target processing scheme based on the abnormal parameters, thereby achieving the same technical effect as the aforementioned digital twin-based substation control method.
[0101] Thirdly, embodiments of this application disclose a computer-readable storage medium, wherein a computer program is stored in the computer-readable storage medium, and when the computer program is loaded by a processor, it executes a digital twin-based substation control method according to the above embodiments.
[0102] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
