[0049] The following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, rather than all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of this application.
[0050] The purpose of this application is to provide a power consumption system abnormality diagnosis method to facilitate solving the problem that the current power consumption system abnormality diagnosis methods are relatively single and have low versatility.

This solution is a series of improvements carried out through the thinking of the fusion model.
[0052] To enable those skilled in the art to better understand the solution of this application, the following will further elaborate on this application in combination with the drawings and specific implementation manners.
[0053] Figure 1 A flowchart of a method for diagnosing abnormalities in an electrical power system provided by an embodiment of the present application. As Figure 1 shown, the method includes:
[0054] S10: Obtain the opening and closing times of the metering door of the electrical power system, the secondary short - circuit power consumption, and the opening time of the electricity meter cover.
[0055] The metering door is the switch of the electricity meter of the electrical power system. Obtaining the opening and closing times of the metering door means obtaining the opening time and the corresponding closing time of the metering door. In this embodiment, the number of times of obtaining the opening and closing times of the metering door, as well as the specific obtaining process, etc. are not limited.
[0056] The primary short - circuit and secondary short - circuit in the circuit represent different short - circuit positions, and cannot be simply understood as short - circuit once and short - circuit twice. In the circuit, taking the transformer as the boundary, the input end is also called the primary end, and the output end is also called the secondary end. If a short - circuit occurs at the input end (primary end), it is called a primary short - circuit; if a short - circuit occurs at the output end (secondary end), it is called a secondary short - circuit. It can be understood that the secondary short - circuit power consumption mentioned in this embodiment is the relevant power consumption change when a secondary short - circuit event occurs. In this embodiment, the number of times of obtaining the secondary short - circuit power consumption and the specific obtaining process are not limited.
[0057] The electricity meter is an instrument used to measure electric energy, also known as a watt - hour meter, a fire meter, a kilowatt - hour meter, referring to an instrument for measuring various electrical quantities. In the case of low voltage (not exceeding 500 volts) and small current (tens of amperes), the electricity meter can be directly connected to the circuit for measurement. In the case of high voltage or large current, the electricity meter cannot be directly connected to the line and needs to be used in conjunction with a voltage transformer or a current transformer. In this embodiment, the specific method of obtaining the opening time of the electricity meter cover is not limited. It should be noted that the opening time of the electricity meter cover in this embodiment refers to a specific time point when the electricity meter cover is opened, such as opening the cover at 2 pm the previous day, rather than the duration from opening the cover to closing the cover.
[0058] S11: Judge whether the opening and closing times of the metering door of the electrical power system, the secondary short - circuit power consumption, and the opening time of the electricity meter cover all meet their respective preset conditions. If so, enter S12; if not, enter S13.
[0059] It should be noted that the preset conditions corresponding to the opening and closing times of the metering door of the electrical power system, the secondary short - circuit power consumption, and the opening time of the electricity meter cover are different. For example, the opening and closing time of the metering door of the electrical power system can be greater than a certain specific value, etc. In this embodiment, the preset conditions corresponding to the above three judgment schemes are not limited, as long as they can judge whether the electrical power system has an abnormality.
[0060] S12: Determine that the electrical power system is normal.
[0061] S13: Determine that the power consumption system is abnormal.
[0062] It should be noted that after determining that the power consumption system is normal or abnormal, it is usually reported to the user side for subsequent processing. In this embodiment, the subsequent steps after the determination of the power consumption system status are not limited.
[0063] The power consumption system abnormal diagnosis method provided by this application determines whether the power consumption system is working properly by counting the metering door, as well as whether the secondary short - circuit and the power consumption system opening time meet the preset conditions. Compared with the existing abnormal diagnosis methods for specific scenarios, since the data involved in the power consumption system abnormal diagnosis method of this application can be obtained on basically all power consumption systems, without showing specific differences due to the use of the power consumption system, it can be determined whether various different power consumption systems are working properly through the above - mentioned data acquisition, so the applicability is relatively strong.
[0064] In the above - mentioned embodiment, how to determine whether the opening and closing time of the metering door of the power consumption system meets the preset conditions is not limited. Here, a preferred solution is proposed. Determining whether the opening and closing time of the metering door of the power consumption system meets the preset conditions includes:
[0065] Obtain the first opening time of the metering door and the installation time;
[0066] Screen out the second opening time of the metering door except for normal situations from the first opening time;
[0067] Determine whether the difference between the second opening time and the installation time is greater than the first threshold;
[0068] If not, determine that the opening and closing time of the metering door of the power consumption system is abnormal;
[0069] If so, determine that the opening and closing time of the metering door of the power consumption system is normal.
[0070] It should be noted that in this embodiment, the specific metering device and related steps for obtaining the first opening time of the metering door and the installation time are not limited. It can be obtained in real - time or by calling the data recorded by relevant devices. It can be understood that the normal situation refers to the normal opening and closing of the metering door, such as the situation of initial installation and normal work orders. For normal work orders, it refers to the daily maintenance of the metering door, etc. Except for the above - mentioned situations, the opening and closing of the metering door are all abnormal situations, and corresponding statistics can be carried out. In this embodiment, the specific value of the first threshold and its corresponding generation method are not limited. It can be understood that generally, it is obtained through multiple metering door time data and the corresponding status tests of the related power consumption systems.
[0071] In this embodiment, it is defined how to determine whether the metering door of the power consumption system is normal by measuring the opening and closing time of the metering door, so as to determine whether the power consumption system is normal and whether there are any abnormal situations according to this information. Moreover, the acquisition of the opening and closing time of the metering door is simple and easy to calculate. Therefore, the technical difficulty and technical cost required for detection are reduced.
[0072] In the above embodiment, the preset conditions for judging the secondary short-circuit power are not defined. Here, a preferred solution is proposed. Judging whether the secondary short-circuit power meets the preset conditions includes:
[0073] Obtaining whether the power difference of the power consumption system within the first preset time before and the first preset time after the occurrence of the secondary short-circuit event exceeds the second threshold;
[0074] If the power difference does not exceed the second threshold, it is determined that the power consumption system is abnormal;
[0075] If the power difference exceeds the second threshold, it is judged whether the power fluctuation within the first preset time before and the first preset time after the occurrence of the secondary short-circuit event is lower than the second threshold / 4;
[0076] If the power fluctuation is higher than the second threshold / 4, it is determined that the secondary short-circuit power of the power consumption system is abnormal;
[0077] If the power fluctuation is lower than the second threshold / 4, it is determined that the secondary short-circuit power of the power consumption system is normal.
[0078] It should be noted that in this embodiment, the time before and after the first preset time in the secondary short-circuit event is the relevant detection time period. For example, the corresponding power is detected one day before and one day after the occurrence of the event, and the difference is obtained by subtracting the powers. Moreover, in this embodiment, the magnitude of the second threshold is not limited. For the second preset time, it can be understood that it is an extension of two time periods before and after a corresponding event based on the first preset time. For example, if the first preset time is one day before and one day after the event, the second preset time is two days before and two days after the event. And in this embodiment, the specific time points of the first preset time and the second preset time are not limited, and the detection device for obtaining the power is also not limited. It is preferably detected by an inspection instrument. In this embodiment, the specific value of the second threshold and its corresponding generation method are not limited. It can be understood that it is generally obtained from multiple secondary short-circuit data and the corresponding state tests of the related power consumption systems.
[0079] In this embodiment, by measuring the secondary short-circuit power, it is detected whether the power consumption system is normal and whether there are any abnormal situations. The acquisition is simple and easy to calculate. Therefore, the technical difficulty and technical cost required for detection are reduced.
[0080] In the above embodiments, there is no limitation on determining whether the opening time of the electricity meter meets the preset conditions. Here, a preferred solution is proposed. Determining whether the opening time of the electricity meter meets the preset conditions includes:
[0081] Obtain the most recent electricity meter opening event, and determine the difference between the time of the electricity meter opening event and the installation time of the electricity meter;
[0082] Judge whether the difference between the time of the electricity meter opening event and the installation time of the electricity meter is greater than the third threshold;
[0083] If so, the secondary short - circuit power of the power consumption system is normal;
[0084] If not, the secondary short - circuit power of the power consumption system is abnormal.
[0085] In this embodiment, there is no specific limitation on the type of the electricity meter and the device and method for obtaining the opening time of the electricity meter. However, generally, the opening information of the electricity meter can be directly obtained by using the data of the collection main station.
[0086] In this embodiment, by measuring the opening time of the electricity meter, it is possible to detect whether the power consumption system is normal and whether there are any abnormal situations. The acquisition is simple and easy to calculate, and it can be directly extracted from the existing device, thus reducing the technical difficulty and technical cost required for detection.
[0087] Considering that the corresponding status information can also be obtained through the switch button box of the electricity meter, here a preferred solution is proposed. This method further includes:
[0088] Obtain the status word of the switch button box of the electricity meter within the third preset time period;
[0089] According to the status word, judge whether the difference between the time when the start button box of the electricity meter is opened and the installation time of the electricity meter is greater than the time threshold;
[0090] If so, the power consumption system is normal;
[0091] If not, the power consumption system is abnormal.
[0092] The status word, also known as the channel status word, is a fixed unit arranged in the main memory to record the execution status of the channel and the device. Channel status word: After the channel is started, it controls the specified device to complete the specified operation. At the same time, during the process of the channel executing the control of the peripheral device, it is necessary to record the execution status of the channel and the device. For this reason, the system arranges another fixed unit in the main memory to store these recorded statuses, and this fixed unit is called the channel status word.
[0093] Generally speaking, when performing the above steps, the normal starting terminal box of the electric energy meter needs to be excluded, such as in the case of initial installation and normal work orders, and at the same time, the situation of time logic errors in the starting terminal box needs to be excluded. In this embodiment, the third preset time is not limited. By detecting whether the difference between the time of the starting terminal box and the installation time of the electric energy meter is greater than the threshold value, it is judged whether the power consumption system is normal. The data acquisition is convenient, the solution is simple, and the applicability is strong.
[0094] Considering that the power consumption system may have multiple failures within a period of time, for the convenience of processing, a preferred solution is proposed here. The method further includes:
[0095] If the power consumption system has two identical abnormal events within the same period of time, it is determined that the second abnormal event is invalid.
[0096] It should be noted that the "same" mentioned here means that the abnormal states are completely the same. For example, the power fluctuations do not meet the preset range and the fluctuation values are equal. In this case, only the first abnormal event needs to be processed, and the second is generally the same derivative of the first event, thus saving labor costs.
[0097] Considering that when the power consumption system is abnormal, the user needs to be reminded to handle it in time, a preferred solution is proposed here. The method further includes:
[0098] When the power consumption system is abnormal, control the alarm device to issue an alarm.
[0099] By issuing an alarm, the user is prompted to handle the abnormal event in time, ensuring the safety of the power consumption system and preventing abnormal events such as electricity theft from causing harm to the power consumption system.
[0100] In the above embodiment, the method for diagnosing the abnormality of the power consumption system is described in detail. The present application also provides an embodiment corresponding to the device for diagnosing the abnormality of the power consumption system. It should be noted that the present application describes the embodiment of the device part from two perspectives, one is from the perspective of functional modules, and the other is from the perspective of hardware.
