Obviously, the drawings described below are only some embodiments of the present application.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] The electric energy meter current overload prevention method provided in the embodiment of the present application is executed by an electronic device, and accordingly, the electric energy meter current overload prevention device operates in the electronic device. The electric energy meter current overload prevention method provided in the embodiment of the present application is described below from the perspective of the electric energy meter current overload prevention device combined with the current monitoring and prevention process.

[0024] like Figure 1 FIG. 1 is a flow chart of a method for preventing electric energy meter current overload provided in an embodiment of the present application. The method for preventing electric energy meter current overload provided in an embodiment of the present application comprises the following steps.

[0025] Step S11, acquiring the current information of the target area in real time according to the collection time interval, and classifying the branches according to the source of the current information.

[0026] The current information is collected in real time by the smart meters installed in each branch. The current information includes but is not limited to the measured current value, and the data is transmitted to the central processor. Then, according to the source of the current information (i.e., the smart meter that transmits the current information), the collected current information is identified and classified according to the branch according to the preset mapping table between the branch and the information source.

[0027] Step S12: Analyze the current power consumption trend of each branch according to the current information, the preset prediction period and the preset trend prediction model.

[0028] The prediction period includes but is not limited to current information and corresponding time tags.

[0029] It should be understood that environmental information has an important impact on the power consumption of the corresponding user. Among them, the current weather information (such as temperature, humidity, sunny or rainy conditions, etc.) and time information (such as season, time period, etc.) have a crucial impact on the user's use of electrical equipment and the choice of power consumption. For example, when the temperature is high in summer, users tend to use cooling equipment such as air conditioners and electric fans, resulting in a significant increase in power consumption.

[0030] After obtaining the time tag, the date and time corresponding to the collected current information are obtained by parsing the time tag. The current weather information and time information are queried according to the date and time. Thus, according to the current weather information and time information, a mapping table between preset environmental information and power consumption impact coefficient is queried to obtain the current power consumption impact coefficient.

[0031] At the same time, the power consumption trend is fitted according to the current value and time information contained in the current information to obtain the power consumption trend fitting line that can directly reflect the power consumption change. And the average change in power consumption used to represent the average change trend of the current within a given collection time interval is calculated according to the following formula: Among them, △E is the average change in electricity consumption, I1, I2, ....I n are all current changes in adjacent acquisition time intervals, n is the number of current changes, and T is the acquisition time interval.

[0032] After obtaining the average change in electricity consumption, the first predicted current is calculated based on the current value obtained in the current collection time interval and the average change in electricity consumption. The first predicted current is the theoretical current value of the next collection time interval inferred based on the average change in electricity consumption. Further, taking into account the actual impact of the environment on the applied electricity, the second predicted current is calculated based on the first predicted current and the current electricity consumption impact coefficient. The second predicted current is the theoretical current value of the next collection time interval inferred after comprehensive environmental coefficients. Then, based on the first predicted current and the second predicted current, the reasonable current range is obtained.

[0033] For example, the average change in electricity consumption is E, the current collection time interval is T, the current electricity consumption impact coefficient is θ, and the current collection current value is I n And, according to the first predicted current calculation formula, the first predicted current is obtained as (I n +ET), the second predicted current obtained by further calculation is θ(I n +ET) and the first predicted current is less than the second predicted current, so according to the first predicted current and the second predicted current, [(I n +ET),θ(I n +ET)].

[0034] Step S13: Acquire historical electricity consumption data according to the time tag.

[0035] Using the time tag as the query condition, the historical current data records close to the current time are retrieved from the database. Furthermore, considering the impact of weather on power consumption, the historical current data records are screened according to the similarity between the current weather information and the historical weather records to obtain a historical current data set that is closer to the current situation.

[0036] Furthermore, after obtaining the historical current data set, the historical power consumption data is obtained according to the preset mean filter calculation. The historical power consumption data is used to represent historical data that is closer to the current power consumption situation. The specific operation is as follows: The N historical current data obtained are arranged from large to small to obtain a sorted data set, and then de-extreme value is performed according to the arrangement order in the sorted data set to remove the maximum and minimum values ​​in the sorted data set and reduce abnormal values ​​generated in special power consumption conditions.

[0037] Then, the historical electricity consumption data is calculated by the following formula: in, is the historical electricity consumption data, are all historical current data in the sorted data set, and (N-2) is the number of data in the sorted data set after depolarization.

[0038] Step S14: judging whether there is abnormal power consumption in each branch according to the preset prevention model, the historical power consumption data and the current power consumption trend.

[0039] After obtaining historical electricity consumption data and current electricity consumption trends, Compare with the reasonable current range to determine whether there is abnormal power consumption in the corresponding branch. When the current is greater than the maximum value of the reasonable range, it is determined that abnormal power consumption exists in the branch.

[0040] Step S15: When there is abnormal power consumption in the branch, overload control is performed on the branch with abnormal power consumption according to a preset preventive control method.

[0041] according to The maximum value of the reasonable current range is calculated, and the difference between the two is calculated (i.e., the overload control parameter). Further, the overload control parameter is compared with the preset control threshold, and the overload control strategy is determined based on it. Among them, the control threshold is designed according to the severity of the overload obtained in the experiment. When the overload control parameter is in a certain threshold range, the overload control strategy is determined according to the mapping table between the preset control threshold and the overload control strategy. Then, the branch with abnormal power consumption is overloaded according to the overload control strategy.

[0042] For example, suppose that in a certain power system, there is a branch with a real-time current value of 120A, and the reasonable current range of the branch is [80A, 100A]. At this time, it is detected that the branch has abnormal power consumption, and the overload control parameter is calculated to be 120A-100A=20A. Among them, the current overload prevention device of the electric energy meter is preset with [0A, 10A], [10A, 20A], [20A, 30A]. By comparing the overload control parameter with the control threshold, it is determined that the overload control parameter 20A falls within the [10A, 20A] interval. According to the preset mapping table, the system finds that the overload control strategy corresponding to the [10A, 20A] interval is "send a warning signal and limit the current to 110A". Therefore, a warning signal is sent to the branch through the automation equipment, and the current limiter is adjusted to limit the current to less than 110A to alleviate the overload situation. At the same time, the system continues to monitor the power consumption of the branch and adjusts the control strategy as needed.

[0043] This application is used in the field of overload prevention. By obtaining the current information of the target area and classifying the branches according to the source of the information, the power consumption trend of each branch is analyzed in detail based on the real-time current information, the preset prediction period and the trend prediction model. At the same time, the corresponding historical power consumption data is obtained according to the time tag, and then the preset prevention model is combined with the historical power consumption data and the current power consumption trend to conduct a comprehensive analysis of each branch to determine whether there is abnormal power consumption in each branch. When abnormal power consumption is detected in the branch, the abnormal branch is overloaded according to the preset prevention control method. This application can timely discover and deal with potential overload risks by real-time monitoring and predicting power consumption trends, thereby effectively avoiding safety accidents such as fire and equipment damage caused by overload of the energy meter.
