[0042] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the following further details the present application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] The voltage regulation method provided in the embodiments of the present application can be applied to, for example Figure 1In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or placed on the cloud or other network servers. The server 104 can obtain the initial output voltage value of the low-voltage side of the hybrid transformer through the data storage system; furthermore, according to the difference between the initial output voltage value and the rated voltage value of the low-voltage side of the hybrid transformer, the on-load voltage regulator and / or the power electronic voltage regulating device can be adjusted to obtain the stable voltage value of the low-voltage side of the hybrid transformer. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

[0044] In an exemplary embodiment, as Figure 2 shown, a voltage regulation method is provided. Taking the method applied to Figure 1 the server 104 in

[0045] as an example for illustration, it may include the following steps:

[0046] Among them, the hybrid transformer includes an on-load voltage regulator and a power electronic voltage regulating device; the initial output voltage value represents the voltage value after passing through the hybrid transformer.

[0047] It should be noted that the initial output voltage value does not meet the voltage requirements of the low-voltage side of the hybrid transformer, that is, it is necessary to adjust the hybrid transformer to achieve the adaptation of the output voltage value.

[0048] Optionally, the on-load voltage regulator is located on the high-voltage side of the hybrid transformer, and the power electronic voltage regulating device is located on the low-voltage side of the hybrid transformer.

[0049] Exemplarily, through a voltage measuring instrument or the monitoring system corresponding to the hybrid transformer, the initial output voltage value of the low-voltage side of the hybrid transformer can be transmitted to the server 104 through a communication module or an internal link for the server 104 to analyze and process it.

[0050] S202, determine the difference between the initial output voltage value and the rated voltage value of the low-voltage side of the hybrid transformer as the voltage regulation value.

[0051] Among them, the rated voltage value can represent the output voltage value of the low-voltage side of the hybrid transformer under rated operating conditions; the voltage regulation value can represent the numerical range within which the hybrid transformer can perform voltage regulation.

[0052] Exemplarily, the rated voltage value of the low-voltage side of the hybrid transformer is directly obtained from a data storage system (when installing the hybrid transformer, information such as the attributes of the hybrid transformer can be saved in the data storage system for subsequent retrieval of the information of the hybrid transformer); furthermore, the difference between the initial output voltage value and the rated voltage value can be directly determined as the voltage regulation value.

[0053] S203, according to the voltage regulation value, adjust the on-load tap-changer and / or the power electronic voltage regulation device to obtain a stable voltage value of the low-voltage side of the hybrid transformer.

[0054] Among them, the on-load tap-changer can adjust the output voltage by switching different voltage regulation positions, that is, to achieve stepped (corresponding to voltage regulation positions) regulation of the voltage; the power electronic voltage regulation device can achieve controllable and continuous regulation of the output voltage through devices such as power semiconductors; the stable voltage value can represent a value close to the rated voltage value of the low-voltage side of the hybrid transformer.

[0055] Exemplarily, according to the magnitude of the voltage regulation value, the voltage regulation position of the on-load tap-changer and / or smooth regulation of small-range voltage fluctuations can be achieved through the power electronic voltage regulation device, and finally precise regulation of the output voltage of the low-voltage side of the hybrid transformer can be achieved to realize stepless voltage regulation.

[0056] The above voltage regulation method provides a direction for determining the voltage regulation scheme by obtaining the initial output voltage value of the low-voltage side of the hybrid transformer including the on-load tap-changer and the power electronic voltage regulation device; further, the difference between the initial output voltage value and the rated voltage value of the low-voltage side of the hybrid transformer can be determined as the voltage regulation value, laying a foundation for realizing precise voltage regulation; furthermore, according to the voltage regulation value, the on-load tap-changer and / or the power electronic voltage regulation device can be adjusted to obtain a stable voltage value of the low-voltage side of the hybrid transformer. This solution realizes precise voltage regulation by introducing a hybrid transformer including an on-load tap-changer and a power electronic voltage regulation device, considering from two dimensions of large-range voltage regulation and small-range voltage regulation.

[0057] Based on the above embodiments, the embodiments of the present application further explain the above embodiment S203 in detail. Specifically, in the embodiments of the present application, the process of adjusting the on-load tap-changer and / or the power electronic voltage regulation device is as Figure 3 shown, and specifically includes the following steps:

[0058] S301. When the absolute value of the voltage regulation value is less than or equal to the first threshold, adjust the power electronic voltage regulator.

[0059] Among them, the first threshold can represent the maximum voltage regulation range of the power electronic voltage regulator. For example, if the first threshold is U, the voltage regulation range of the power electronic voltage regulator is ±U.

[0060] Exemplarily, when the absolute value of the voltage regulation value is small, that is, -U ≤ voltage regulation value ≤ +U, which means that the minimum voltage regulation gear of the on-load tap changer exceeds the regulation amplitude corresponding to the voltage regulation value. At this time, the power electronic voltage regulator can be directly adjusted to smooth the voltage fluctuation.

[0061] S302. When the absolute value of the voltage regulation value is greater than the first threshold and less than or equal to the second threshold, adjust the on-load tap changer and the power electronic voltage regulator.

[0062] Among them, the second threshold can represent the maximum voltage regulation value that can be jointly achieved by the on-load tap changer and the power electronic voltage regulator. Optionally, the second threshold is greater than the first threshold.

[0063] It should be noted that when the absolute value of the voltage regulation value is greater than the second threshold, it indicates that the required voltage regulation amplitude has exceeded the maximum voltage regulation capacity of the hybrid transformer.

[0064] One implementation method is that when the absolute value of the voltage regulation value is greater than the first threshold and less than or equal to the third threshold, determine the target regulation gear of the on-load tap changer according to the absolute value of the voltage regulation value; adjust the on-load tap changer according to the target regulation gear to obtain the first output voltage value of the low-voltage side of the hybrid transformer; adjust the power electronic voltage regulator based on the difference between the first output voltage value and the rated voltage value.

[0065] Among them, the third threshold can represent the maximum voltage regulation range of the on-load tap changer, and the third threshold is greater than the first threshold and less than the second threshold. For example, if the third threshold is V, the voltage regulation range of the on-load tap changer is ±V.

[0066] Optionally, the second threshold is the sum of the third threshold and the first threshold. For example, the second threshold = U + V.

[0067] In the above example, when the absolute value of the voltage regulation value is greater than the first threshold (U) and less than or equal to the third threshold (V), that is, within the voltage regulation range of the on-load tap-changer, the voltage regulation gear closest to the absolute value of the voltage regulation value in the on-load tap-changer can be determined as the target regulation gear; further, the on-load tap-changer can be directly adjusted according to the target regulation gear, that is, a large-scale adjustment of the output voltage is realized through the on-load tap-changer in the hybrid transformer, and the first output voltage value of the low-voltage side of the hybrid transformer is obtained; further, the remaining small-scale voltage (i.e., the difference between the first output voltage value and the rated voltage value) is adjusted through the power electronic voltage regulation device in the hybrid transformer, that is, the power electronic voltage regulation device is adjusted based on the difference between the first output voltage value and the rated voltage value.

[0068] Another implementation method is that when the absolute value of the voltage regulation value is greater than the third threshold and less than or equal to the second threshold, the on-load tap-changer is adjusted according to the maximum voltage gear of the on-load tap-changer to obtain the second output voltage value of the low-voltage side of the hybrid transformer; the power electronic voltage regulation device is adjusted based on the difference between the second output voltage value and the rated voltage value.

[0069] Among them, the third threshold is greater than the first threshold and less than the second threshold.

[0070] Exemplarily, when the third threshold (V) < the absolute value of the voltage regulation value ≤ the second threshold (U + V), that is, within the maximum voltage regulation range of the on-load tap-changer and the power electronic voltage regulation device, the on-load tap-changer can be adjusted according to the maximum voltage gear of the on-load tap-changer, that is, the maximum-scale adjustment of the output voltage is realized through the on-load tap-changer in the hybrid transformer, and the second output voltage value of the low-voltage side of the hybrid transformer is obtained; further, the remaining small-scale voltage (i.e., the difference between the second output voltage value and the rated voltage value) is adjusted through the power electronic voltage regulation device in the hybrid transformer, and the power electronic voltage regulation device is adjusted.

[0071] In the embodiments of the present application, by introducing the first threshold and the second threshold, precise adjustment of the output voltage value of the low-voltage side of the hybrid transformer is realized.

[0072] Based on the above embodiments, this embodiment provides an optional example of a voltage regulation method. As Figure 4 shown, the specific implementation process is as follows:

[0073] S401, obtain the initial output voltage value of the low-voltage side of the hybrid transformer.

[0074] Among them, the hybrid transformer includes an on-load tap-changer and a power electronic voltage regulating device. Optionally, the on-load tap-changer is located on the high-voltage side of the hybrid transformer, and the power electronic voltage regulating device is located on the low-voltage side of the hybrid transformer.

[0075] S402. Determine the voltage regulation value as the difference between the initial output voltage value and the rated voltage value of the low-voltage side of the hybrid transformer.

[0076] S403. Determine whether the absolute value of the voltage regulation value is less than or equal to the first threshold value; if so, execute S404; if not, execute S405-S406.

[0077] S404. Adjust the power electronic voltage regulating device to obtain the stable voltage value of the low-voltage side of the hybrid transformer.

[0078] S405. Determine whether the absolute value of the voltage regulation value is less than or equal to the second threshold value; if so, execute S406.

[0079] S406. Adjust the on-load tap-changer and the power electronic voltage regulating device to obtain the stable voltage value of the low-voltage side of the hybrid transformer.

[0080] One implementation method is that when the absolute value of the voltage regulation value is greater than the first threshold value and less than or equal to the third threshold value, determine the target regulation gear of the on-load tap-changer according to the absolute value of the voltage regulation value; where the third threshold value is greater than the first threshold value and less than the second threshold value; adjust the on-load tap-changer according to the target regulation gear to obtain the first output voltage value of the low-voltage side of the hybrid transformer; based on the difference between the first output voltage value and the rated voltage value, adjust the power electronic voltage regulating device.

[0081] Among them, the second threshold value is the sum of the third threshold value and the first threshold value.

[0082] Another implementation method is that when the absolute value of the voltage regulation value is greater than the third threshold value and less than or equal to the second threshold value, adjust the on-load tap-changer according to the maximum voltage gear of the on-load tap-changer to obtain the second output voltage value of the low-voltage side of the hybrid transformer; where the third threshold value is greater than the first threshold value and less than the second threshold value; based on the difference between the second output voltage value and the rated voltage value, adjust the power electronic voltage regulating device.
