Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0040] Example 1, reference Figure 1-Figure 2 , which is the first embodiment of the present invention, and which provides a power grid power supply range positioning system, comprising:

[0041] The present application provides a method for effectively solving the above-mentioned problems. Next, multiple embodiments will be combined to explain in detail how to implement the power grid power supply range positioning system;

[0042] Figure 1 A method flow chart of a power grid power supply range positioning system and method is shown, including:

[0043] There are power supply system module, power grid power supply station, data integration interaction module, record acquisition module, power supply range analysis module, power supply positioning module, marking display module, system interface module and system monitoring module;

[0044] The supporting device of the power supply range analysis module is a power distribution voltage device, and the power distribution voltage device is connected to the power distribution meter, and a GPS positioning device is installed inside the power distribution meter;

[0045] The GPS positioning device is a supporting device inside the power supply positioning module.

[0046] The power supply system module can control the power supply station of the power grid to supply power to the city-level area, thereby ensuring normal electricity supply within the city-level area.

[0047] The data integration interaction module can be used to establish a user information interaction and data integration platform within the city-level area, so that it can interact with several distributed systems and obtain user information archive data within the city-level area.

[0048] The record acquisition module can obtain the user's electricity consumption event records within the city area in real time through the smart meter HPLC module, such as: electricity consumption time, electricity consumption frequency or electricity consumption and electricity charges and other information.

[0049] The first level module in the power supply range analysis module is the city-level regional range, the second level module is the district-level regional range, the third level module is the street-level regional range, and the fourth level module is the community-level regional range. The regional range becomes smaller level by level and can eventually be reduced to the community-level regional range.

[0050] The GPS positioning device includes a positioning transmitter, which can use the positioning transmitter to send a signal to the GPS positioning satellite, so that the GPS positioning satellite can receive the signal sent by the positioning transmitter and feedback the signal, so that the positioning receiver can receive the feedback signal from the GPS positioning satellite, so that the GPS positioning device can locate the position through the feedback signal from the GPS positioning satellite.

[0051] The power supply positioning module can determine the specific location of the distribution meter based on the location determined by the GPS positioning device, and the range is within the community area. At this time, the entire range of power supply of the power grid can be determined, including the municipal area range, district area range, street area range and community area range.

[0052] The labeling display module can display the location information of the distribution meter, such as a street or a community in a certain district of a city, so that positioning operations can be performed within the power supply range.

[0053] The system interface can display the information displayed by the annotation display module on the system interface, so that users can intuitively understand the location and positioning information of the distribution meter.

[0054] The system monitoring module is connected to each module to monitor each module. When an abnormality occurs in a module, it can be fed back to the system interface, so that users can intuitively understand the abnormality of the system at the first time.

[0055] When in use, the user can supply power to the city-level area from the power supply station through the power supply system module, so as to ensure normal power supply in the city-level area, so that the power supply system module can control the power supply station. At this time, the data integration interaction module can be used to establish a user information interaction and data integration platform in the city-level area, so as to interact with several distributed systems, so as to obtain user information archive data in the city-level area. At the same time, the record acquisition module can work normally, so that the record acquisition module can obtain the user power consumption event records in the city-level area in real time through the smart meter HPLC module, such as: power consumption time, power consumption frequency or power consumption and electricity charges and other information;

[0056] The HPLC module can realize high-frequency acquisition of voltage, current and other data, which mainly uses algorithms such as fast Fourier transform (FFT) to achieve high-precision acquisition and analysis of power parameters.

[0057] Fourier transform (abbreviated as FT) is a mathematical transformation that converts a signal from the time domain to the frequency domain. Its basic idea is to decompose a complex signal into a series of simple sine waves and cosine waves. Fourier transform has a wide range of applications in signal processing, image processing, physics, and engineering.

[0058] The mathematical expression of Fourier transform is:

[0059] F(ω)=∫[f(t) / e^(-jωt)dt]

[0060] Where ω is the frequency, t is the time, f(t) is the time domain signal, and j is the imaginary unit.

[0061] However, in practical applications, directly calculating the Fourier transform may be very time-consuming, especially for signals with large amounts of data. Therefore, the discrete Fourier transform (DFT for short) is widely used in digital signal processing. DFT discretizes the time domain signal into a finite number of sample points and obtains the corresponding discrete spectrum in the frequency domain.

[0062] The mathematical expression of discrete Fourier transform is:

[0063] F[k]=∑[f[n]*e^(-j(2πnk / N))]

[0064] Where k and n are the indices of discrete sample points, and N is the total number of sample points.

[0065] In order to improve computational efficiency, the Fast Fourier Transform (FFT) algorithm was proposed. FFT is an efficient method for calculating DFT. It greatly reduces the amount of calculation by decomposing the DFT calculation process into a series of smaller calculation steps. The time complexity of the FFT algorithm is O(NlogN), which is much lower than the O(N^2) of directly calculating DFT.

[0066] The basic idea of ​​the FFT algorithm is to decompose the DFT calculation process into a series of butterfly operations. Butterfly operation is an operation that multiplies and adds two complex numbers. Its characteristic is that both the input and output are two complex numbers. By decomposing the DFT calculation process into butterfly operations, the FFT algorithm can recursively calculate the DFT, thereby improving the calculation efficiency.

[0067] The supporting device of the power supply range analysis module is a distribution voltage device, and the distribution voltage device is connected to the distribution meter. A GPS positioning device is installed inside the distribution meter. The GPS positioning device belongs to the supporting device inside the power supply positioning module. The first-level module in the power supply range analysis module is the city-level regional range, the second-level module is the district-level regional range, the third-level module is the street-level regional range, and the fourth-level module is the community-level regional range. The regional range becomes smaller step by step and can eventually be reduced to the community-level regional range. The GPS positioning device includes a positioning transmitter, which can use the positioning transmitter to send a signal to the GPS positioning satellite, so that the GPS positioning satellite can receive the signal sent by the positioning transmitter and feedback the signal, so that the positioning receiver can receive the feedback signal of the GPS positioning satellite, so that the GPS positioning device can locate the position through the feedback signal of the GPS positioning satellite. After that, the power supply positioning module can determine the specific location of the distribution meter according to the position determined by the GPS positioning device, and the range is within the community-level range. At this time, the entire range of power supply of the power grid can be determined, including the city-level regional range, the district-level regional range, the street regional range and the community regional range.

[0068] Finally, the annotation display module can display the location information of the distribution meter, such as a certain street or a certain community in a certain district of a city, so that positioning operations can be performed within the power supply range. The system interface can display the information displayed by the annotation display module on the system interface, so that users can intuitively understand the location-related information of the distribution meter.

[0069] The system monitoring module is connected to each module and can monitor each module. When an abnormality occurs in a module, it can be fed back to the system interface, so that users can intuitively understand the abnormal points of the system at the first time, and then enable users to quickly carry out targeted maintenance on the abnormal module, so that the entire system can quickly return to normal.

[0070] The present invention can quickly and accurately locate the meter within the city-level area by setting a power supply range analysis module, a distribution meter equipped with a GPS positioning device, and a power supply positioning module. The specific principle is: the GPS positioning device includes a positioning transmitter, and the positioning transmitter can be used to send a signal to the GPS positioning satellite, so that the GPS positioning satellite can receive the signal sent by the positioning transmitter and feedback the signal, so that the positioning receiver can receive the feedback signal of the GPS positioning satellite, so that the GPS positioning device can locate the position through the feedback signal of the GPS positioning satellite. After that, the power supply positioning module can determine the specific position of the distribution meter according to the position determined by the GPS positioning device, and the range is within the community area. At this time, the entire range of power supply of the power grid can be determined, including the city-level area, district-level area, street area and community area.

[0071] Finally, the annotation display module can display the location information of the distribution meter, such as a certain street or a certain community in a certain district of a city, so that positioning operations can be performed within the power supply range. The system interface can display the information displayed by the annotation display module on the system interface, so that users can intuitively understand the location-related information of the distribution meter.

[0072] The present invention can connect the system monitoring module with each module by setting up a system monitoring module, and monitor each module. When an abnormality occurs in a module, it can be fed back to the system interface, so that the user can intuitively understand the abnormal point of the system at the first time, and then the user can quickly carry out targeted maintenance on the abnormal module, so that the entire system can quickly return to normal.

[0073] Furthermore, this embodiment also provides a method for locating a power supply range of a power grid, including:

[0074] The power supply system module controls the power supply station of the power grid to supply power within the municipal area;

[0075] The data integration and interaction module establishes a user information interaction and data integration platform within the city-level area. At the same time, the record acquisition module obtains the user electricity consumption event records within the city-level area in real time through the smart meter HPLC module;

[0076] The power supply range analysis module is based on the power supply information provided by the power supply system module. It analyzes the power supply conditions at the city level, district level, street level, and community level in turn through the first-level module, the second-level module, the third-level module, and the fourth-level module. The power supply positioning module determines the specific location of the distribution meter based on the GPS positioning device installed in the distribution meter.

[0077] The marking display module displays the location information of the distribution meter and displays the location information on the system interface through the system interface module. At the same time, the system monitoring module is connected to each module to monitor each module in real time. Once a module abnormality is found, the abnormal information is immediately fed back on the system interface.

[0078] This embodiment also provides a computer device, which may be a terminal, and its internal structure diagram may be as shown in FIG. Figure 2 As shown. The computer device includes a processor, a memory, a communication interface, a display screen and an input device connected through a system bus. Among them, the processor of the computer device is used to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium. The communication interface of the computer device is used to communicate with an external terminal in a wired or wireless manner, and the wireless manner can be achieved through WIFI, an operator network, NFC (near field communication) or other technologies. When the computer program is executed by the processor, a power grid power supply range positioning system is implemented. The display screen of the computer device can be a liquid crystal display screen or an electronic ink display screen, and the input device of the computer device can be a touch layer covered on the display screen, or a button, trackball or touchpad set on the computer device housing, or an external keyboard, touchpad or mouse.

[0079] This embodiment further provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the following steps are implemented:

[0080] It includes power supply system module, power grid power supply station, data integration interaction module, record acquisition module, power supply range analysis module, power supply positioning module, marking display module, system interface module and system monitoring module;

[0081] The supporting device of the power supply range analysis module is a power distribution voltage device, and the power distribution voltage device is connected to a power distribution meter, and a GPS positioning device is installed inside the power distribution meter;

[0082] The GPS positioning device is a matching device inside the power supply positioning module.

[0083] Example 2, reference Figure 1 - Figure 2 , which is the second embodiment of the present invention, and this embodiment provides a power grid power supply range positioning system. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0084] In order to verify the effectiveness and innovation of the power grid power supply range positioning system of the present invention, a typical city was specially selected as the test site. This city has multiple residential areas, commercial areas and industrial areas of different sizes, which can fully reflect the power supply conditions of the power grid in various practical application scenarios. Before the test, the power supply system module of the present invention was first deployed at the power grid power supply station of the selected city to ensure that it can stably provide electricity to the entire municipal area. Next, distribution meters were installed at various important nodes in the city, including distribution transformers, and GPS positioning devices were installed inside the distribution meters. In addition, a data integration interaction platform was established to facilitate the collection and analysis of real-time electricity consumption data from the HPLC module of the smart meter.

[0085] During the test, the power supply range analysis module was activated and began to analyze the power supply situation in detail according to the first to fourth level modules. This process not only involves the monitoring of power distribution from power supply stations to various regions, but also includes an in-depth study of power consumption patterns in specific areas. In order to ensure positioning accuracy, the GPS positioning device uses its built-in positioning transmitter to communicate with the GPS positioning satellite to accurately determine the location of the distribution meter. Subsequently, the power supply positioning module further processes this location information to ensure that the location of each distribution meter can be accurately captured by the annotation display module and presented on the system interface. At the same time, the system monitoring module continuously monitors the operating status of the entire system to ensure that any abnormal situation can be responded to in a timely manner.

[0086] In order to more intuitively demonstrate the effect of the present invention, a set of control experiments was also set up, that is, without using the system of the present invention, the traditional method was used to locate and analyze the power supply situation of the power grid in the same area. Both sets of experiments were carried out in the same time period to ensure the fairness and accuracy of the comparison results.

[0087] Table 1 Experimental data table

[0088]

[0089] It can be seen from the data comparison in the above table that the power supply range positioning system of the present invention has shown significant advantages in many aspects. First, from the perspective of positioning accuracy, the traditional method can only achieve an accuracy of 50 meters, while the system of the present invention can improve the positioning accuracy to 5 meters, which means that the actual location of each distribution meter can be more accurately grasped for the power company, thereby optimizing the layout and maintenance of the power grid. Secondly, in terms of data update frequency, the system of the present invention reaches 60 times per hour, which is much higher than the 1 time / hour of the traditional method, which shows that the system of the present invention can provide more real-time data support, which helps to timely discover and solve problems in the operation of the power grid. Furthermore, the location recognition time and the abnormal detection response time are shortened to 5 seconds and 5 seconds respectively in the system of the present invention, compared with 60 seconds and 300 seconds of the traditional method, which undoubtedly greatly improves the reaction speed and emergency handling capability of the system. In addition, the average power parameter error is also reduced from 5% of the traditional method to 0.5% of the system of the present invention, indicating that the system of the present invention has higher accuracy in the collection and analysis of power parameters. Finally, the significant improvement in user satisfaction reflects from another aspect the superior performance of the system of the present invention in practical applications, with up to 95% of users expressing satisfaction, a figure far exceeding the 60% of traditional methods.

[0090] In summary, the power grid power supply range positioning system of the present invention has not only achieved multiple breakthroughs at the technical level, but also demonstrated obvious superiority in practical applications, providing strong technical support for the efficient operation and high-quality services of power companies.
