[0041] Example 1, reference Figure 1-Figure 5 , which is the first embodiment of the present invention, provides a power grid power supply tracking system, including:

[0042] 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 tracking system;

[0043] Figure 1 A system structure diagram of a power grid power supply tracking system and method is shown, including:

[0044] A power grid power supply tracking system includes a power grid power supply station, a high-voltage generator set, a power transformer, a public distribution box, a household distribution box, public electrical equipment, household electrical equipment, a power supply tracking module and a system interface module;

[0045] The power grid power supply station is used to generate and provide 10KV high voltage power; the power grid power supply station includes a 10KV high voltage generator set, and the 10KV high voltage generator set provides power to the power transformer through a high voltage conductor;

[0046] High-voltage generator set, located in the power supply station of the power grid, is used to generate 10KV high-voltage power and provide it to the power transformer through high-voltage wires;

[0047] Power transformers are used to receive power from high-voltage generators and convert it into a voltage suitable for use by household or public electrical equipment;

[0048] The power tracking module is used to be installed on electrical equipment to reversely track the source and path of the power supply through the power tracker;

[0049] The system interface module is used to display the power supply source and path information traced by the power tracking module.

[0050] Furthermore, the wires between the 10KV high-voltage generator set and the power transformer will be connected to a lightning arrester, which contains a lightning protection grounding wire, which will be inserted under the ground surface, so as to play the role of conducting lightning protection;

[0051] The power transformer will be electrically connected to the public distribution box / domestic distribution box through wires, and the public distribution box / domestic distribution box will be electrically connected to the public electrical equipment / domestic electrical equipment through wires;

[0052] The wires between the power transformer and the public distribution box / domestic distribution box are all connected to relay protectors, which protect the wires between the power transformer and the public distribution box / domestic distribution box;

[0053] Public electrical equipment includes road lights, signal lights, landscape lights and other public electrical equipment;

[0054] Household electrical appliances include air conditioners, washing machines, ceiling lamps and other household electrical appliances;

[0055] Public electrical equipment / household electrical equipment are electrically connected to the power tracking module through wires.

[0056] Furthermore, the power tracking module includes a power tracker, which can be used to reversely track the source and path of the power supply, and finally display the source and path of the power supply in the system interface.

[0057] Further, the power transformer is provided with a high voltage isolating switch, and the power transformer is connected with an L1 line, an L2 line, an L3 line and a neutral line;

[0058] The L1 line connected to the power transformer is yellow, the L2 line is green, and the L3 line is red. All of them are live wires, and the neutral wire is blue. The power transformer is connected to a neutral grounding wire. The power transformer is equipped with a high-voltage disconnector. The high-voltage disconnector is installed by professionals from the Power Supply Bureau, and the high-voltage disconnector can be used under load. The power transformer is connected to L1, L2, L3 and a neutral wire. All of them are live wires, and the neutral wire is blue. The power transformer is connected to a neutral grounding wire. The neutral grounding wire will be inserted under the ground, so that it can play a role in conducting lightning and avoiding lightning, and then it can protect the power transformer, and then it can avoid the high voltage generated by lightning strikes on the power transformer causing short circuit or even explosion of the power transformer.

[0059] Furthermore, the main structure of the power system includes power source, power network and load center. Power source refers to various types of power plants and stations, which convert primary energy into electrical energy; the power network is composed of power source step-up substations, transmission lines, load center substations, distribution lines, etc.; its function is to boost the electrical energy generated by the power source to a certain level and then transmit it to the load center substation, and then reduce the voltage to a certain level before connecting it to the user through the distribution line; there are thousands of network nodes in the power system, and active power flow, reactive power flow, high-order harmonics, negative sequence current, etc. are transmitted throughout the system at the speed of light; it can not only transmit a large amount of electrical energy and create huge wealth, but also cause major catastrophic accidents in an instant. In order to ensure the safe, stable and economical operation of the system, various automatic control devices and communication systems must be configured at different levels according to different requirements to form information and control subsystems; it becomes a neural network to realize the information transmission of the power system, making the power system observable and controllable, thereby ensuring the normal progress of the power production and consumption process and emergency handling under accident conditions. The operation of the system means that all links that make up the system are in a state of performing their functions; during the operation of the system, the random changes in the power load and various external interferences (such as lightning strikes, etc.) will affect the stability of the power system, resulting in fluctuations in the system voltage and frequency, thereby affecting the quality of the system power, and in severe cases, causing voltage collapse or frequency collapse; the system operation is divided into normal operation state and abnormal operation state; among them, the normal state is divided into safe state and warning state; the abnormal state is divided into emergency state and recovery state. The operation of the power system includes all these states and their transitions. The transition between various operating states needs to be achieved through different control methods; under the premise of ensuring the quality of electric energy and achieving safe and reliable power supply, the power system should also achieve economic operation, that is, strive to adjust the load curve, improve equipment utilization, rationally utilize various power resources, reduce fuel consumption, plant electricity and power network losses, so as to achieve the best economic benefits.

[0060] It should be noted that, according to the size of the installed capacity and power load in the power system, as well as the relative position of the power source and the load center, the power system often adopts different voltage levels of transmission (such as high voltage transmission or ultra-high voltage transmission) to obtain the best technical and economic benefits. According to the characteristics of the current, the power system's transmission mode is also divided into AC transmission and DC transmission. AC transmission is the most widely used. DC transmission is the transmission of the electric energy generated by the AC generator after rectification using DC. Due to the restrictions of natural resource distribution and economic development level, the power source and the load center are mostly in different regions. Since electric energy cannot be stored in large quantities at present, and the transmission process is essentially carried out at the speed of light, the production of electric energy must always be balanced with consumption. Therefore, the centralized development and decentralized use of electric energy, as well as the continuous supply of electric energy and the random changes in load, have become the fundamental characteristics that restrict the structure and operation of the power system.

[0061] When in use, the power grid power supply station includes a 10KV high-voltage generator set, which can be used to provide power to the power transformer through high-voltage wires. The wires between the 10KV high-voltage generator set and the power transformer are connected to lightning arresters. The lightning arresters include lightning protection grounding wires. The lightning protection grounding wires will be inserted under the ground surface, so as to play a role in conducting lightning and thus protect the power transformer, thereby preventing the high voltage generated by lightning strikes from causing short circuits or even explosions in the power transformer. The power transformer will be electrically connected to the public distribution box / household distribution box through wires, and the public distribution box / household distribution box will be connected to the public through wires. Electrical appliances / household appliances are electrically connected, and the wires between the power transformer and the public distribution box / household distribution box are connected to relay protectors. The relay protectors protect the wires between the power transformer and the public distribution box / household distribution box. Public electrical appliances include public electrical appliances such as road lights, signal lights, and landscape lights. Household electrical appliances include household electrical appliances such as air conditioners, washing machines, and ceiling lamps. Public electrical appliances / household appliances are electrically connected to the power tracking module through wires. The power tracking module includes a power tracker. The power tracker can be used to reversely track the source and path of the power supply, and finally display the source and path of the power supply in the system interface.

[0062] Furthermore, the power transformer is provided with a high-voltage isolating switch, which is installed by professionals of the power supply bureau and can be used under load. The power transformer is connected with L1 line, L2 line, L3 line and neutral line. The L1 line connected to the power transformer is yellow, the L2 line is green, and the L3 line is red. The L1 line, L2 line and L3 line are all live wires, and the neutral line is blue. The power transformer is connected with a neutral point grounding wire, which will be inserted under the ground surface, so as to play a role of conducting lightning and thus protect the power transformer, thereby preventing the high voltage generated by lightning from causing the power transformer to short-circuit or even explode. The voltage calculation formula in the power tracker is:

[0063] V OUT =V ADJ +ΔV

[0064] Among them, V OUT is the output voltage of the power tracker, V ADJ is the input voltage, and ΔV is the deviation between the output voltage and the input voltage.

[0065] The present invention is provided with a power tracking module on the public electrical equipment / household electrical equipment, and the power tracking module includes a power tracker. The power tracker can be used to track the transportation route and power source of the power supply in reverse and upward step by step, so that it can be tracked back to the public distribution box / household distribution box, and then back to the power transformer, and then back to the high-voltage generator set, so that it can finally be tracked back to the power supply station of the power grid. At this time, the system can display the information such as the transportation route and power source of the power supply on the system interface, so that the user can clearly know the power supply route and power source of the public electrical equipment / household electrical equipment. The lightning protection grounding wire will be inserted under the surface of the ground, so that it can play a conductive role. The effect of lightning protection can protect the power transformer, thereby preventing the high voltage generated by lightning from causing short circuit or even explosion of the power transformer. The wires between the power transformer and the public distribution box / household distribution box will be connected to relay protection devices, which will protect the wires between the power transformer and the public distribution box / household distribution box. The power transformer is connected to a neutral point grounding wire, which will be inserted under the ground surface, thereby playing a role of conductive lightning protection, thereby protecting the power transformer, thereby preventing the high voltage generated by lightning from causing short circuit or even explosion of the power transformer.

[0066] Furthermore, the present embodiment also provides a method for tracing a power supply of a power grid, comprising: a 10KV high-voltage generator set in a power supply station of the power grid provides a 10KV high-voltage power supply to a power transformer through a high-voltage conductor;

[0067] The power transformer receives power from the 10KV high-voltage generator set and converts it into a voltage suitable for use by household electrical appliances or public electrical appliances;

[0068] The wires between the power transformer and the public distribution box and the household distribution box are connected with relay protectors, which protect the wires between the power transformer and the public distribution box and the household distribution box;

[0069] The power tracker in the power tracking module reversely tracks the source and path of the power supply and sends the tracking result to the system interface module.

[0070] 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 supply tracking system for the power grid is realized. 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 covering the display screen, or a button, trackball or touchpad set on the computer device housing, or an external keyboard, touchpad or mouse.

[0077] 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 tracking system. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0078] In order to verify the effectiveness and innovation of the power supply tracking system, an experiment was designed and conducted in a typical community power grid environment in a certain city. The main goal of the experiment was to test the performance of the system in a real environment, especially the accuracy of power supply tracking and the stability of the system.

[0079] Participating equipment: 10KV high-voltage generator set, power transformer, public distribution box, household distribution box, public electrical equipment (such as road lights, signal lights), household electrical equipment (such as air conditioners, washing machines)

[0080] A 10KV high-voltage generator set is installed in the power supply station of the power grid, and a 10KV high-voltage power supply is provided to the power transformer through a high-voltage wire.

[0081] The wires between the high-voltage generator set and the power transformer are connected to the lightning arrester, and the lightning protection grounding wire of the lightning arrester is inserted below the ground surface to a depth of 1.5 meters to ensure the lightning protection effect.

[0082] The power transformer is installed in the center of the community and is electrically connected to the public distribution box and the household distribution box through wires. The public distribution box and the household distribution box are then electrically connected to the public electrical equipment and the household electrical equipment through wires.

[0083] Install relay protectors on the wires between the power transformer and the public and household distribution boxes to protect the wires from overload or short circuit.

[0084] A power tracking module is installed on each public electrical equipment and household electrical equipment. The power tracking module includes a power tracker for reversely tracing the source and path of the power supply.

[0085] The power tracker is connected to electrical equipment through wires to ensure the accuracy and real-time nature of data collection.

[0086] A system interface module is installed in the management center of the community, and the module is used to display the power supply source and path information tracked by the power supply tracking module.

[0087] The system interface module is connected to the power tracking module through a network to receive and display the power tracking data in real time.

[0088] During the experiment, the 10KV high-voltage generator set continued to operate, providing a stable high-voltage power supply.

[0089] Power transformers convert high voltage power to a voltage suitable for use by household and public electrical equipment.

[0090] The power tracking module automatically performs power tracking every 10 minutes and sends the tracking results to the system interface module.

[0091] The system interface module displays the power tracking results in real time, including the source, path and voltage changes of the power supply.

[0092] During the experiment, record the results of each power supply trace, including the source, path, voltage change, etc. Summarize the data and form a table for subsequent analysis.

[0093] Table 1 Power tracing result record table

[0094]

[0095] Table 2 Voltage change record

[0096]

[0097] As can be seen from Table 1, the power sources of all test objects are power supply stations, and the paths are high-voltage generators, power transformers, public distribution boxes or household distribution boxes. This shows that the power tracking module can accurately track the source and path of the power supply, verifying the effectiveness of the system.

[0098] Especially for public electrical equipment (such as street lights and traffic lights) and household electrical equipment (such as air conditioners and washing machines), the power tracking module can accurately identify their respective distribution boxes, demonstrating the applicability and reliability of the system in practical applications.

[0099] Table 2 records the voltage values ​​of each path from the high-voltage generator set to the final output voltage. From the data, it can be seen that after the 10KV voltage output by the high-voltage generator set is converted by the power transformer, the final output voltage is stabilized at around 220V, which meets the use requirements of household electrical appliances and public electrical appliances.

[0100] The voltage deviation (ΔV) is small, with a maximum of only 0.7V, which shows that the power tracker has high accuracy in calculating the output voltage and can accurately reflect the actual voltage changes.

[0101] During the experiment, the wires between the power transformer and the public distribution box and the household distribution box were connected with relay protection devices. During the entire experiment, no overload or short circuit occurred, indicating that the relay protection devices effectively protected the safety of the wires.

[0102] The lightning protection grounding wire of the lightning arrester was inserted beneath the ground. During the experiment, thunderstorms occurred several times, but the system operated normally without any lightning damage, verifying the effectiveness of the lightning arrester.

[0103] The system interface module displays the power supply tracking results in real time, including the source, path and voltage changes of the power supply. The staff of the community management center can understand the power supply status of each electrical equipment at any time through the system interface module, which improves the efficiency and accuracy of management.

[0104] During the experiment, the data of the system interface module was updated in a timely manner without any delay, indicating that the system has good real-time performance and stability.

[0105] Compared with the prior art, the grid power supply tracking system of the present invention can not only accurately track the source and path of the power supply, but also display the voltage changes in real time, providing a new tool for the management and maintenance of the power system.

[0106] It can be seen from the experimental data that the present invention performs well in practical applications, especially in terms of the accuracy of power supply tracking and the stability of voltage changes, which far exceeds the existing technology. In addition, the protection function and real-time performance of the system also provide a strong guarantee for the safe operation of the power system.

[0107] In summary, the grid power supply tracking system of the present invention has shown significant advantages in practical applications.
