Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and in particular to a control method and system for a medium-voltage intelligent circuit breaker. Background Art

[0002] Since its invention and use, electricity has brought both convenience and devastating consequences. Due to its elusiveness and difficulty in human control, electricity can, in some cases, burn out electrical appliances, cause fires, or even cause electric shocks. To address these issues, circuit breakers were developed. Circuit breakers are crucial control and protection devices in low-voltage power distribution systems. They rapidly interrupt fault currents in the event of overloads or short circuits, protecting the distribution system and its electrical equipment. They can also be used for infrequent on-off control operations. The stability and reliability of circuit breaker performance are crucial for protecting the distribution system, electrical equipment, and personal and property safety.

[0003] However, traditional circuit breakers lack power detection, communication, and remote control capabilities, making it impossible to monitor the breaker's status and associated power levels, or to control its opening and closing. In practice, power companies encourage residents to take advantage of preferential off-peak electricity prices by consuming large amounts of off-peak electricity, such as electric water heaters, air conditioners, and other electrical appliances. Furthermore, for power companies, shifting peak power consumption to off-peak periods not only alleviates the supply-demand gap during peak hours but also promotes the optimal allocation of power resources, creating a win-win strategy of "peak shaving and valley filling." Therefore, intelligent control of circuit breakers, enabling them to automatically detect peak and off-peak power consumption, shift power consumption during peak periods, and reduce circuit load, remains a pressing challenge.

[0004] The prior art includes an invention entitled "An Intelligent Circuit Breaker System Capable of Energy Management," which includes a number of circuit breakers, each connected to an electrical appliance or a group of electrical appliances, for obtaining real-time power consumption information of the electrical appliance or group of electrical appliances; a cloud platform, connected to the circuit breakers, for obtaining real-time power consumption information transmitted by the circuit breakers and processing the power consumption information to obtain power consumption behavior information, and setting the optimal opening time information of the corresponding circuit breaker based on billing method information; wherein the cloud platform includes: a storage unit, a behavior analysis unit, and an optimal opening time determination unit. This system automatically obtains the most cost-effective opening time of an electrical appliance or group of electrical appliances based on the user's actual power consumption behavior and the metering method of electricity charges, thereby saving electricity costs without the need for specific circuit breakers. Although this invention can only control circuit breakers, it cannot shift peak power consumption and reduce circuit load. Summary of the Invention

[0005] The purpose of the present invention is to overcome the problem in the prior art that circuit breakers cannot be intelligently controlled, so that they can automatically detect peak power consumption and low power consumption, shift power consumption during peak power consumption, and reduce circuit load. A control method and system for a medium-voltage intelligent circuit breaker are provided, which can intelligently control the opening and closing of the circuit breaker, automatically determine peak power consumption, thereby shifting peak power consumption, reducing circuit load, alleviating the supply and demand gap of peak power, and promoting the optimal allocation of power resources.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: a control method for a medium voltage intelligent circuit breaker, characterized in that it includes the following steps:

[0007] S1: The user selects the electrical equipment connected to the first power-off system and the electrical equipment connected to the second power-off system of the medium-voltage intelligent circuit breaker;

[0008] S2: Collect user electricity consumption data in real time to determine whether a single user is a low-power user or a high-power user;

[0009] S3: Based on the electricity consumption data of all users, determine whether the current time is peak or off-peak. If it is off-peak, continue monitoring. If it is peak, execute step S4.

[0010] S4: Send a power-off request to low-power users and a high-power-usage warning to high-power users;

[0011] S5: The low-power user decides whether to disconnect the circuit. If the low-power user agrees, the medium-voltage intelligent circuit breaker opens and disconnects the circuit.

[0012] S6: Determine whether the peak power consumption has ended. If so, close the medium voltage intelligent circuit breaker to restore power supply.

[0013] This invention monitors user electricity usage in real time, determines whether it is high or low, and further determines whether the current period is peak or off-peak. If it is off-peak, it sends a power-off request to low-consumption users and then controls the medium-voltage intelligent circuit breaker to cut off power, thereby shifting peak electricity consumption. This invention reduces circuit load, alleviates the gap between peak power supply and demand, and promotes the optimal allocation of power resources.

[0014] Preferably, in step S1, the electrical devices connected to the first power-off system of the medium-voltage intelligent circuit breaker are devices that do not require continuous power supply, including water dispensers and water heaters, and the electrical devices connected to the second power-off system of the medium-voltage intelligent circuit breaker are devices that require continuous power supply, including refrigerators. Users can choose which devices to connect to, whether they cannot be powered off or can be powered off, based on their needs, providing greater flexibility and convenience.

[0015] Preferably, the step S2 further comprises:

[0016] S2.1: Preset user power usage threshold;

[0017] S2.2: Collecting real-time user electricity usage data, including AC current, voltage, active power, reactive power, and power factor;

[0018] S2.3: Compare the collected electricity consumption data of a single user with a preset threshold value. If three of the data exceed the threshold value, it indicates that the user is a high electricity consumption user. Otherwise, it indicates that the user is a low electricity consumption user.

[0019] Thresholds can be set to determine whether a user's current electricity usage is high or low. To prevent inaccurate data from problems with monitoring equipment, multiple types of electricity usage information are monitored to improve monitoring accuracy.

[0020] Preferably, in step S3, the data analysis system combines all the user's electricity consumption data to determine whether it is a peak electricity consumption or a valley electricity consumption. The specific steps are:

[0021] S3.1: Set the threshold for peak power consumption, the threshold for the rate of increase in power consumption, and the duration t;

[0022] S3.2: Integrate all user electricity consumption data, draw a real-time total electricity consumption curve, and calculate the total electricity consumption growth rate;

[0023] S3.3: Determine whether the total power consumption at this time exceeds the preset value. If not, continue monitoring. If so, execute step S3.4;

[0024] S3.4: Determine whether the peak power consumption time exceeds the duration t, and determine whether the total power consumption growth rate at this time is lower than the threshold. If the peak power consumption time is higher than the threshold and the total power consumption growth rate is higher than the threshold, it means that this is the peak power consumption time.

[0025] If a user's total electricity usage exceeds the threshold at a given moment, it's likely due to a sudden change in usage for some reason, and doesn't necessarily mean the peak will persist. Therefore, to determine if the current peak is occurring, you need to confirm that total electricity usage remains above the threshold and that there's no downward trend in total electricity usage growth. This effectively reduces the likelihood of power-off requests being sent to users.

[0026] Preferably, the step S4 further comprises:

[0027] S4.1: The control system sends a power-off request to the terminal device of the low-power-consumption user through the communication system, asking the low-power-consumption user whether to accept the power-off request;

[0028] S4.2: The control system sends a control command to the medium voltage intelligent circuit breaker;

[0029] S4.3: The alarm device on the medium voltage intelligent circuit breaker is activated to remind high power consumption users that they are in a high power consumption state.

[0030] Preferably, in step S5, the low-power user decides whether to disconnect the circuit. If the low-power user agrees, the medium-voltage intelligent circuit breaker is opened as follows: the low-power user selects whether to disconnect the power and whether to disconnect the electrical equipment of the first or second power-off system according to their needs. During the opening process of the medium-voltage intelligent circuit breaker, the user can choose to connect the electrical equipment at any time to control the closing of the medium-voltage intelligent circuit breaker. During the opening process of the medium-voltage intelligent circuit breaker, if the user needs to restore power due to personal needs, they can choose to restore power on the terminal device, thereby controlling the closing of the medium-voltage intelligent circuit breaker. This is flexible and highly practical.

[0031] Preferably, in step S6, the data analysis system determines whether the peak electricity consumption has ended at this time by the following specific steps:

[0032] S6.1: Determine whether the total power consumption at this time exceeds the preset value. If it exceeds, it means that the power consumption is still at the peak. If it does not exceed, execute step S6.2;

[0033] S6.2: Determine whether the total power consumption growth rate is lower than a threshold. If the total power consumption growth rate is lower than the threshold, it indicates that the peak power consumption period has ended.

[0034] S6.3: The medium-voltage intelligent circuit breaker is closed, and the storage system stores the electricity consumption data of individual users;

[0035] S6.4: At the end of each month, a monthly electricity consumption report is generated based on the stored electricity consumption data and sent to the user.

[0036] The fact that the current total power consumption does not exceed the threshold does not mean that the current peak power consumption has ended. It is necessary to continue to determine whether the current total power consumption growth rate is lower than the threshold.

[0037] Preferably, in step S6.4, the monthly electricity consumption report includes: peak electricity consumption periods for all users, whether the user is a low- or high-consumption user during each peak period, and the number of times the user disconnected electrical equipment during peak periods. Through the monthly report, users can clearly understand their electricity usage and peak periods, thereby avoiding peak periods or controlling the opening of medium-voltage smart circuit breakers in advance.

[0038] A control system for a medium voltage intelligent circuit breaker, characterized by comprising:

[0039] Control system: controls the medium voltage intelligent circuit breaker to open and close, issues alarms, and sends instructions to the communication system and storage system;

[0040] Medium-voltage intelligent circuit breaker: includes a primary power-off system, a secondary power-off system, and an alarm device, used to control the on / off of different electrical equipment and alert users;

[0041] Communication system: Send a power-off request to the low-battery user terminal device through the APP;

[0042] Storage system: stores user electricity usage data;

[0043] Terminal device: receives power-off request from the control system and sends user reply instruction to the control system;

[0044] The control system includes:

[0045] Data acquisition system: including voltage sensors and current sensors, used to collect user electricity consumption data in real time and transmit the collected data to the data analysis system;

[0046] Data analysis system: Analyzes and classifies individual user data based on data from the data acquisition system; integrates all user electricity consumption data, plots total electricity consumption curves, and generates electricity consumption reports.

[0047] The data acquisition system is connected to the data analysis system, the control system is connected to the storage system, the communication system, the first power-off system, the second power-off system, and the alarm device, and the communication system is connected to the terminal device. The alarm device can be an audible or visual alarm, or simply a buzzer. The terminal device can be a mobile phone, to which the control system sends a text message via the communication system; or it can be an app, to which the control system sends a power-off request via the communication system. The storage system can be a memory.

[0048] Therefore, the present invention has the following beneficial effects: 1. By collecting user electricity consumption data, it can automatically determine peak electricity consumption and low electricity consumption, thereby shifting peak electricity consumption, reducing circuit load, and alleviating the gap between supply and demand of peak electricity; 2. It can intelligently control the opening and closing of circuit breakers without the need for manual control, reducing labor costs and promoting the optimal allocation of power resources; 3. It can push energy consumption reports to users every month, so that users can understand their electricity consumption during peak electricity consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0053] like Figure 1 In the illustrated embodiment, a control method for a medium-voltage intelligent circuit breaker can be seen, and its operating process is as follows: Step 1, the user selects the electrical equipment of the first power-off system and the electrical equipment of the second power-off system connected to the medium-voltage intelligent circuit breaker; Step 2, the user's power consumption data is collected in real time to determine whether the individual user is a low-power consumption user or a high-power consumption user; Step 3, based on the power consumption data of all users, it is determined whether this is a peak power consumption or a low-power consumption period. If it is a low-power consumption period, monitoring continues; Step 4, if it is a peak power consumption period, a power-off request is sent to the low-power consumption user, and a high-power consumption warning is sent to the high-power consumption user; Step 5, the low-power user decides whether to disconnect the circuit. If the low-power user agrees, the medium-voltage intelligent circuit breaker disconnects the circuit; Step 6, it is determined whether the peak power consumption period is over. If it is over, the medium-voltage intelligent circuit breaker resumes power supply.

[0054] This invention monitors user electricity usage in real time, determines whether it is high or low, and further determines whether the current period is peak or off-peak. If it is off-peak, it sends a power-off request to low-consumption users and then controls the medium-voltage intelligent circuit breaker to cut off power, thereby shifting peak electricity consumption. This invention reduces circuit load, alleviates the gap between peak power supply and demand, and promotes the optimal allocation of power resources.

[0055] like Figure 2 In the embodiment shown, a control system for a medium voltage intelligent circuit breaker can be seen, including:

[0056] A control system 1 controls the opening and closing of a medium-voltage intelligent circuit breaker, issues an alarm, and sends instructions to a communication system and a storage system. It includes a first power-off system 3, a second power-off system 4, and an alarm device 5, for controlling the on and off of different electrical devices and alerting users of excessive power consumption. A communication system 6 sends power-off requests to a low-power user terminal device 7 via an app. A storage system 8 stores user power consumption data. A control system receives power-off requests from the control system and sends user response instructions to the control system terminal device 7. The control system includes a data acquisition system 9, which includes voltage and current sensors and is used to collect user power consumption data in real time and transmit the collected data to a data analysis system. A data analysis system 10 analyzes and classifies individual user data based on the data from the data acquisition system. The data acquisition system is connected to the data analysis system, the control system is connected to the storage system, the communication system, the first power-off system, the second power-off system, and the alarm device, and the communication system is connected to the terminal device.

[0057] Voltage sensors collect voltage data, and current sensors collect current data. The data acquisition system also collects active power, reactive power, and power factor. This data is then transmitted to the data processing system for processing and to the storage system for storage. The data processing system analyzes and processes the data to determine whether a user is a low- or high-power user, and whether the current time is peak or off-peak. If the user is experiencing peak power usage, the control system sends a power-off request to the low-power user's terminal device via the communication system. The low-power user then selects whether to shut down the power, using either the first or second power-off system, based on their needs. The terminal device then relays the user's selection back to the control system via the communication system. The control system generates a control command to the medium-voltage intelligent circuit breaker, which closes the circuit. Simultaneously, the control system sends a control command to the high-power user's medium-voltage intelligent circuit breaker, activating the alarm device to alert the user that the current time is peak power usage and that the user is experiencing high power usage. The user can then decide whether to shut down individual electrical devices. At the same time, the data processing system can also generate a monthly electricity consumption report for users based on the electricity consumption monitoring situation of the month, and send the report to the user's terminal device through the communication system.

[0058] The following further illustrates the technical solutions and technical effects of the present invention through specific examples. The following examples are intended to explain the present invention, but the present invention is not limited to the following examples.

[0059] Step 1: The user selects the electrical equipment connected to the medium voltage intelligent circuit breaker

[0060] The intelligent circuit breaker includes two power-off systems: the primary and secondary. The primary is used to connect devices that don't require constant power, such as water dispensers and water heaters; the secondary is used to connect devices that do require constant power, such as refrigerators. Users can choose between connected devices that can and cannot be disconnected, providing greater flexibility and convenience. This reduces the likelihood of users choosing to continue powering on due to concerns about devices that cannot be disconnected.

[0061] Step 2: The data collection system collects users' real-time electricity consumption data, and the data analysis system determines whether a single user is a low-power user or a high-power user.

[0062] Whether the user's current time is high or low electricity consumption can be determined by setting a threshold. First, the user's electricity consumption threshold is preset; then the user's real-time electricity consumption data is collected. In order to prevent problems with the monitoring equipment that lead to inaccurate data, a variety of electricity consumption information is monitored to improve the accuracy of monitoring. The electricity consumption data includes AC current, voltage, active power, reactive power, and power factor. The collected electricity consumption data of a single user is compared with the preset threshold. If three of the data exceed the threshold, it means that the user is high electricity consumption. Otherwise, it means that the user is low electricity consumption.

[0063] Step 3: The data analysis system combines all user electricity consumption data to determine whether this is peak or low electricity consumption.

[0064] Set a peak power consumption threshold, a power consumption increase rate threshold, and a duration t; integrate all user power consumption data, plot a real-time total power consumption curve, and calculate the total power consumption growth rate; determine whether the total power consumption at that moment exceeds the preset value; if not, continue monitoring. If a user's total power consumption at a given moment exceeds the threshold, it is likely due to a sudden change in power consumption for some reason and does not mean that the current peak power consumption will be sustained. Therefore, it is necessary to ensure that the total power consumption during the current period is consistently above the threshold and that there is no downward trend in total power consumption growth to determine that the current period is peak power consumption. Therefore, it is necessary to determine whether the peak power consumption duration exceeds the duration t and whether the total power consumption growth rate during this period is below the threshold. If the peak power consumption duration is above the threshold and the total power consumption growth rate is above the threshold, it indicates that the current period is peak power consumption. This can effectively reduce the situation where power outage requests are continuously sent to users.

[0065] Step 4: Send power-off requests to low-power users and high-power users a high-power warning

[0066] The control system sends a power-off request to the terminal devices of low-power users through the communication system, asking them whether they accept the power-off request. Simultaneously, the control system sends a control instruction to the medium-voltage intelligent circuit breaker, activating the alarm device on the medium-voltage intelligent circuit breaker to alert high-power users that they are in a high-power consumption state.

[0067] Step 5: The low-power user decides whether to disconnect the circuit. If the low-power user agrees, the medium-voltage intelligent circuit breaker disconnects the circuit.

[0068] Low-power users can choose whether to disconnect power based on their needs, and whether to disconnect devices in the first or second disconnection systems. If a user needs to restore power while the medium-voltage intelligent circuit breaker is open, they can restore power at any time on their terminal device, thereby controlling the closing of the medium-voltage intelligent circuit breaker. This provides flexibility and high practicality.

[0069] Step 6: Determine whether the peak power consumption has ended. If so, the medium voltage intelligent circuit breaker will restore power supply.

[0070] Determine whether the total power consumption at this time exceeds the preset value. If it exceeds, it means that it is still in the peak power consumption period. If it does not exceed, determine whether the total power consumption growth rate at this time is lower than the threshold. If the total power consumption growth rate is lower than the threshold, it means that the peak power consumption period has ended. The medium-voltage intelligent circuit breaker is closed, and the storage system stores the power consumption data of a single user. At the end of the month, a monthly power consumption report is generated based on the stored power consumption data and sent to the user. The content of the power consumption report includes the peak power consumption periods of all users, whether the user is a low-power user or a high-power user during each peak power consumption period, and the number of times the user chooses to disconnect the power equipment during the peak power consumption period. Through the monthly report, users can clearly understand their own power consumption status and peak time periods, so that they can avoid peak power consumption in advance or control the opening of the medium-voltage intelligent circuit breaker in advance.

[0071] The embodiment described above is only a preferred solution of the present invention and does not limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solution described in the claims.
