[0057] Example 2, reference Figure 1-Figure 4 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the voltage unit 100 further includes a load monitoring module 103, which monitors the load current and power of the power grid;

[0058] The load monitoring module 103 is installed on the key line behind the grid access module 101, monitors the load current and power parameters of the grid in real time, and transmits the load information to the data processing center 203 and the control instruction generation module 302, realizes the monitoring function through current transformers and power sensors, and is connected to other modules through communication cables.

[0059] The data unit 200 also includes a communication module 204, which is connected to the data processing center 203 to realize communication between the device and an external power grid monitoring system or a remote control center.

The communication module 204 has an encrypted communication function and uses the Advanced Encryption Standard (AES) algorithm to encrypt the transmitted data to ensure the security and privacy of the communication.

[0060] The voltage module also includes a backup power module 104, which is connected to the voltage distribution module 102. When the power grid is out of power or the voltage is abnormal, resulting in insufficient power supply to the device, it provides temporary power support to the key modules to ensure the basic operation of the device and data security.

[0061] Furthermore, the voltage detection module 201, including a voltage amplitude sensor 201a, a frequency sensor 201b and a phase sensor 201c, is distributed in each branch of the output end of the voltage distribution module 102, detects the voltage signal in real time, including the parameters of voltage amplitude, frequency and phase, and transmits the detection data to the data acquisition module 202. It is connected to the data acquisition module 202 through a shielded signal line to prevent signal interference.

It is connected to the grid access module 101 through a power cable to achieve the regulation of the grid voltage.

[0064] The remaining structures are the same as those of Example 1.

[0065] In terms of voltage detection, a combination of high-precision, wide-bandwidth Rogowski coil voltage sensors and capacitive voltage divider voltage sensors is used, which not only improves the detection accuracy, but also broadens the frequency response range, ensuring that no tiny voltage change information is missed. In the voltage regulation execution module 401, the adjustable transformer, reactive power compensation device and power electronic converter cooperate with each other to perform coarse and fine adjustments on the voltage amplitude respectively, and adjust the reactive power to stabilize the voltage. In particular, the power electronic converter adopts a multi-level topology structure, which greatly reduces the harmonic content in the voltage regulation process and improves the power quality. This all-round high-precision technology application from detection to execution enables the grid voltage to operate in a state closer to the ideal state, meeting the strict requirements of modern power systems for high-quality electricity. Whether it is for sensitive electronic equipment or large industrial equipment, it can provide stable and high-quality power supply, reducing equipment loss and production loss caused by power quality problems.

[0066] The communication module 204 not only realizes the communication between the device and the external power grid monitoring system or the remote control center, but also can upload important information such as the operating status, voltage data and diagnostic results of the device, and can also receive external scheduling instructions and parameter update instructions. Moreover, the communication module 204 has an encrypted communication function, and uses an advanced encryption standard algorithm to encrypt the transmitted data, thereby ensuring the security and privacy of communication and preventing information leakage and malicious attacks. During the operation of the voltage regulation execution module 401, the operating status of the regulation equipment is monitored in real time. Once a fault occurs, the communication module 204 can be used to promptly alarm the external system and start the backup regulation strategy, further enhancing the reliability of the entire system and the ability to cope with faults, so that the present invention can operate stably and safely in actual power grid applications, providing strong support for the intelligent management and reliable power supply of the power grid.

[0067] Example 3, reference Figure 1-Figure 4 , which is the third embodiment of the present invention, discloses a method for regulating an adaptive voltage regulating device of a power grid, comprising the following steps:

[0068] S1. Connect the device to the power grid through the grid access module 101. When connecting to the grid, the grid access module 101 first automatically detects and matches the grid voltage level and phase to ensure safe access. Then, the voltage distribution module 102 reasonably distributes the connected voltage to subsequent modules to ensure that each module obtains a suitable voltage supply.

[0069] S2. Use the voltage detection module 201 to detect the allocated voltage in real time, and convert the detected voltage signal into a digital signal through the data acquisition module 202 and perform preliminary sorting. When the data acquisition module 202 samples the voltage signal, the sampling frequency is automatically adjusted according to the frequency change of the grid voltage to ensure the integrity of the sampled data;

[0070] S3, the voltage data processed by the data acquisition module 202 is transmitted to the data processing center 203, the data processing center 203 analyzes the historical data in the storage module, and sends the data to the intelligent diagnosis module 3017 for intelligent diagnosis to determine whether the voltage is abnormal;

[0071] S4, the control instruction generation module 302 generates corresponding control instructions according to the analysis results of the data processing center 203 and the diagnosis results of the intelligent diagnosis module 3017, taking into account the load information obtained by the load monitoring module 103, and transmits them to the voltage regulation execution module 401 through the instruction transmission module 303;

[0072] S5. The voltage regulation execution module 401 regulates the grid voltage according to the received control instruction. After the regulation is completed, the voltage detection module 201 detects the voltage again and feeds back the new voltage data to the data processing center 203 to perform the next round of voltage regulation cycle to achieve adaptive voltage regulation.

[0073] In the data processing and diagnosis step, the intelligent diagnosis module 301 regularly updates the diagnosis model and optimizes the model using new voltage anomaly case data to improve the diagnosis accuracy.

[0074] In the control instruction generation step, after generating the instruction, the control instruction generation module 302 first performs simulation verification of the instruction, evaluates the validity of the instruction by simulating the power grid response, and regenerates the instruction if it is invalid.

[0075] In the voltage regulation and feedback step, the voltage regulation execution module 401 monitors the operating status of the regulation equipment in real time during the voltage regulation process. If a fault occurs, the communication module 204 is notified in time to alarm the external system and start the backup regulation strategy.

[0076] The working principle and use process of the present invention are as follows: first, the device is connected to the power grid through the grid access module 101. When the grid access module 101 is connected to the grid, it first automatically detects and matches the grid voltage level and phase to ensure safe access. Then, the voltage distribution module 102 reasonably distributes the connected voltage to the subsequent modules to ensure that each module obtains a suitable voltage supply. The voltage detection module 201 is used to perform real-time detection on the distributed voltage, and the detected voltage signal is converted into a digital signal through the data acquisition module 202 and preliminarily sorted. When the data acquisition module 202 samples the voltage signal, the sampling frequency is automatically adjusted according to the frequency change of the grid voltage to ensure the integrity of the sampled data. The voltage data processed by the data acquisition module 202 is transmitted to the data The processing center 203 and the data processing center 203 analyze the historical data in the storage module and send the data to the intelligent diagnosis module 301 for intelligent diagnosis to determine whether the voltage is abnormal. The control instruction generation module 302 generates corresponding control instructions based on the analysis results of the data processing center 203 and the diagnosis results of the intelligent diagnosis module 301, while considering the load information obtained by the load monitoring module 103, and transmits them to the voltage regulation execution module 401 through the instruction transmission module 303. The voltage regulation execution module 401 adjusts the grid voltage according to the received control instructions. After the adjustment is completed, the voltage detection module 201 detects the voltage again and feeds back the new voltage data to the data processing center 203 for the next round of voltage regulation cycle to achieve adaptive voltage regulation.
