Description

Technical Field

[0001] The present application relates to the technical field of transformer control, and in particular to a transformer adaptive regulation control method. Background Art

[0002] In modern power systems, transformers, as key power transmission and conversion equipment, undertake important functions such as voltage regulation and power distribution. Traditional transformer architectures usually use fixed parameter configurations. When a transmission path is overloaded due to load mutation, equipment failure, or fluctuations in renewable energy output, it often relies on global protection mechanisms (such as fusing or tripping) to forcibly cut off the abnormal path, which not only leads to local energy efficiency imbalance, such as increased local overload losses and increased temperature, but also may cause cascading failure risks. In the prior art, the parameter fixation characteristics of a single transformer make it difficult to dynamically divide the load of the abnormal path, and there is a lack of collaborative control strategies between multiple transformers, making it impossible to achieve multi-level transfer and redistribution of overload energy. In addition, the signal transmission loss compensation mechanism after path switching is imperfect, which further aggravates the energy efficiency loss of power supply, making the traditional transformer adjustment method unable to meet the needs of fast response, high efficiency and stability. In particular, in AC transmission systems, the dynamic adjustment capability of transformers is particularly important, because the complexity and load volatility of AC transmission networks put forward higher requirements on the response speed and stability of transformers. Therefore, there is an urgent need for a new transformer control method that can achieve dynamic optimization of energy efficiency through intelligent means under load fluctuations or abnormal conditions, so as to improve the fault tolerance, stability and energy efficiency of the power system. Summary of the invention

[0010] The embodiment of the present application provides a transformer adaptive regulation and control method to solve the technical problem that the transformer cannot dynamically optimize the energy efficiency distribution under load fluctuations or abnormal operating conditions during power supply, resulting in aggravated local overload losses and reduced system operation stability. It realizes two-stage adaptive power distribution based on path-level load identification, realizes dynamic migration and coordinated transformation of abnormal loads through parameter decoupling, and significantly improves the technical effects of fault tolerance and energy efficiency balance of multi-path transformation.

[0011] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0012] It should be noted that the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or server that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or modules that are not explicitly listed or inherent to these processes, methods, products or devices.

[0013] Examples, such as Figure 1 As shown, the present application provides a transformer adaptive regulation control method, the method comprising: A transformer module is constructed, wherein the transformer module includes a first transformer and a second transformer, wherein the first transformer is a main transformer and the second transformer is a secondary transformer.

[0014] In an embodiment of the present application, the core of the construction of the transformer module is to achieve dynamic load regulation and fault-tolerant control of abnormal paths through the collaborative architecture of the first and second transformers, wherein the first transformer is the main transformer, which is the core energy transmission unit and is responsible for the main voltage conversion function; the second transformer is the sub-transformer, which is an auxiliary regulation unit and is deployed in parallel with the main transformer. It is in a low-power standby mode under normal circumstances and is used to assist the main transformer in its work and coordinately regulate voltage changes in the system. The main transformer and the sub-transformer together constitute a transformer module to better distribute the load and optimize the stability and efficiency of power transmission.

[0015] Acquire multiple transformation paths of the first transformer, perform operation monitoring on the multiple transformation paths respectively, and output multiple groups of operation monitoring data sets.

[0016] In one embodiment, in a transformer module, a first transformer forms multiple independent transformation paths through a multi-winding structure and a multi-port design. Current sensors and voltage sensors are deployed at the input and output ends of each transformation path to capture the instantaneous current, voltage waveform and effective value of the path in real time. Distributed temperature sensors (such as optical fiber temperature measurement units) are embedded in key nodes of the path (such as winding connections and magnetic cores) to monitor the temperature rise gradient of the path during operation. Through these sensors, the operation status of these paths is monitored, and the operation status of each transformation path is tracked and recorded in real time to generate multiple sets of operation monitoring data sets. These data sets include various performance indicators of different transformation paths during operation, such as current, voltage, temperature, load conditions, etc. These monitoring data provide a basis for subsequent analysis and help evaluate the stability of the transformation path and whether there are any abnormalities.

[0017] Furthermore, the present application provides that after outputting multiple sets of operation monitoring data sets, the method further includes: The multiple groups of operation monitoring data sets are analyzed to obtain load stability; when the load stability is less than the preset load stability, a flexible load control instruction is connected, and flexible load adjustment is performed on the multiple transformer paths according to the flexible load control instruction.

[0018] Preferably, after obtaining multiple groups of operation monitoring data sets, multiple groups of load information, including load current and load power, are extracted from the multiple groups of operation monitoring data sets; then, the maximum value and minimum value of the load current of each group of load information are used to make a difference to obtain the current fluctuation amplitude of each group, and the absolute difference between adjacent time points of each group of load information and the time difference are used to perform ratio calculation, and then the calculation results are accumulated and divided by the calculated ratio quantity to obtain the average current change rate of each group, and the current standard deviation of each group is calculated using the standard deviation calculation formula, and then the maximum and minimum value normalization method is used to normalize the obtained current fluctuation amplitude, average current change rate, and current standard deviation to obtain the standard current fluctuation amplitude, standard current average change rate, and standard current standard deviation, and the same operation is performed on the load power to obtain the standard power fluctuation amplitude, standard power average change rate, and standard power standard deviation; then, the standard current fluctuation amplitude, standard current average change rate, and standard current standard deviation are normalized. Add, add the standard power fluctuation amplitude, the standard power average change rate and the standard power standard deviation, and then perform weighted calculation on the two summed results to obtain the load stability value; then, compare the load stability value with the preset load stability. If the load stability is less than the preset load stability, a connection will be established with the set flexible load control instruction, and according to this flexible load control instruction, the transformer paths whose load stability is less than the preset load stability are flexibly load adjusted, wherein the flexible load control instruction is a dynamic adjustment mechanism, which can timely adjust the working state of the transformer path according to the actual load fluctuation to reduce the impact of load instability. This adjustment includes adjusting the output voltage of the transformer, changing the load distribution, etc., to achieve load balance and stable operation. For example, by changing the power distribution of each transformer path, the load of the path with a higher load is appropriately reduced, while the load of the path with a lower load is increased, so that the system load is balanced. In this way, it is possible to flexibly respond to load fluctuations, thereby maintaining the smooth operation of the transformer path and avoiding overload or efficiency reduction problems caused by load instability.

[0019] Load anomaly identification is performed on the multiple groups of operation monitoring data sets to determine abnormal voltage transformation paths that are greater than a preset load index.

[0020] In one embodiment, the load current, load power, output voltage, etc. of each transformer path are extracted from multiple groups of operation monitoring data sets, and by comparing these data, it is possible to identify which transformer paths have obvious abnormal loads. In the load abnormality identification process, firstly, preset load indicators, such as maximum load current, maximum power, and maximum output voltage, are loaded. These preset load indicators are used to determine whether each transformer path is within the normal working range; then, by comparing the load current, load power, output voltage, etc. of each transformer path with these preset load indicators, those transformer paths whose loads exceed the preset indicators are identified. For example, if the preset load indicators include the maximum load current, maximum power, and maximum output voltage, which are 100A, 200kW, and 240V, respectively, and the load current of a certain transformer path is 120A, the load power is 250kW, and the output voltage is 250V, the transformer path has data exceeding the preset load indicators, so the transformer path will be marked as an abnormal transformer path. Through the above analysis, it is possible to determine which transformer paths have abnormal loads, especially those paths whose loads exceed preset indicators, and mark them as abnormal transformer paths, thereby providing data support for subsequent adjustment and optimization.

[0021] The voltage transformation parameters corresponding to the abnormal voltage transformation path are determined, the voltage transformation parameters are adaptively separated according to the preset load index, and a first voltage transformation parameter and a second voltage transformation parameter are output.

[0022] In one embodiment, an abnormal transformer path whose load exceeds a preset load index is identified, and transformer parameters related to the path are extracted. These transformer parameters include key parameters such as input voltage, output voltage and voltage ratio, which can directly affect the operation effect of the transformer path; then, the transformer parameters of the abnormal transformer path are adaptively separated according to the preset load index. The purpose of this process is to optimize the distribution of transformer parameters while maintaining the normal operation of the transformer path, thereby improving the overall stability of the system. The adaptive separation process will finely adjust the transformer parameters according to the preset load index (such as maximum load current, maximum power, etc.) to ensure that the transformer parameters of each transformer path operate within a reasonable range; through adaptive separation, two sets of transformer parameters suitable for the abnormal transformer path will be output, namely the first transformer parameter and the second transformer parameter, which correspond to the working states of the first transformer and the second transformer, respectively, and ensure that under abnormal load conditions, the transformer path can effectively adjust and adapt to different working conditions to avoid overload and instability, thereby improving the energy efficiency and stability of the system.

[0023] Furthermore, the present application provides a method for adaptively separating the voltage transformation parameters based on the preset load index and outputting a first voltage transformation parameter and a second voltage transformation parameter, the method comprising: Among them, the transformation parameters corresponding to the abnormal transformation path include input voltage, output voltage and voltage ratio; obtain real-time load indicators of the transformation parameters, including load current, power and voltage; obtain the load indicator difference between the real-time load indicator and the preset load indicator, and adaptively separate the transformation parameters to minimize the load indicator difference, and output a first transformation parameter and a second transformation parameter, the first transformation parameter includes a first input voltage, a first output voltage and a first voltage ratio, and the second transformation parameter includes a second input voltage, a second output voltage and a second voltage ratio.

[0024] Preferably, relevant transformation parameters, including input voltage, output voltage and voltage ratio, are obtained from multiple transformation paths, and then real-time load indicators of each path are obtained, which include load current, load power and output voltage, for example, the input voltage is 110V, the output voltage is 250V, the load current is 120A, and the load power is 250kW; then, preset load indicators are read, including maximum load current, maximum power, and maximum output voltage, for example, the maximum load current is 100A, the maximum power is 200kW, and the maximum output voltage is 240V, and the difference in load indicators is calculated by comparing the real-time load indicator with the preset load indicator, for example, the load current difference is 20A, the load power is 200kW, and the maximum output voltage is 240V. The power difference is 50kW and the output voltage difference is 10V; afterwards, according to the real-time load index difference, the transformer parameters are adaptively adjusted to reduce the impact of overload and optimize load adaptability to ensure that the transformer path can adapt to abnormal loads. In this process, the goal is to minimize the load index difference to ensure that the output load current, voltage and power can be close to the preset standards without causing overload or performance degradation. Under normal circumstances, the original voltage ratio is maintained at 2 (output voltage 220V and input voltage 110V). At this time, its current capacity is constrained within the 100A threshold, and the corresponding power upper limit is 220V*100A=22kW. However, due to abnormal load, by increasing the voltage ratio to 2.8 (output voltage 240 V and input voltage 110V), using the power carrying advantage brought by the output voltage increase, under the same current capacity, the power limit is extended to 24kW, which is 9.1% higher than the original design. This adjustment is essentially to reconstruct the voltage and current space. When the total load current reaches 120A, the main path bears 80A (corresponding to a power of 17.6kW), and the remaining 40A is carried by the secondary path at 240V voltage (9.6kW). The total power of 27.2kW is still lower than the 200kW system limit. This strategy uses adaptive separation of voltage ratios to improve the power transmission efficiency per unit current of the abnormal path without exceeding the output voltage limit of 240V, thereby covering the power gap with a lower current increment. In addition, the current capacity and power limit will also increase with the adjustment of the transformation parameters in order to adapt to higher load requirements; finally, through this adaptive separation, the output transformation parameters include a first transformation parameter and a second transformation parameter. The first transformation parameter is suitable for a normal load path, bears the basic load, has a voltage ratio of 2, an input voltage of 110V, and an output voltage of 220V; the second transformation parameter is suitable for an abnormal load path, absorbs part or all of the excess voltage, has a voltage ratio of 2.18, an input voltage of 110V, and an output voltage of 240V. By minimizing the load indicator difference, it can ensure the optimal regulation of voltage and power under abnormal load conditions, thereby improving the stability and operation efficiency of the system.

[0025] Furthermore, the present application provides that after obtaining multiple transformation paths of the first transformer, the method further includes: Obtain a connection interface corresponding to the abnormal transformation path in the first transformer; perform temperature monitoring on the connection interface, and when the interface temperature is greater than a preset temperature threshold, update the first transformation parameter and the second transformation parameter with the preset temperature threshold to obtain updated first transformation parameter and second transformation parameter.

[0026] Preferably, a connection interface corresponding to the abnormal transformation path is obtained. The connection interface is usually a connection point between the transformer and the load, which may be a cable, terminal or other electrical connection component. The electrical performance of the load and its temperature state can be obtained by monitoring these interfaces. Once the connection interface is obtained, the temperature sensor will be started to monitor the interface in real time. The temperature sensor will continuously detect the temperature change of the interface and record the interface temperature. Subsequently, the interface temperature is compared with a preset temperature threshold. When the interface temperature is greater than the preset temperature threshold, the first transformation parameter and the second transformation parameter will be updated according to the temperature condition. For the first transformation parameter, the difference between the interface temperature and the preset temperature threshold is multiplied by the unit temperature adjustment amount to obtain the parameter value to be adjusted, and the input voltage or the output voltage is reduced according to this value to reduce the load and reduce the interface temperature. For the second transformation parameter, the voltage ratio will be increased according to the reduced amount to balance the load and avoid further temperature rise. After temperature monitoring and transformation parameter adjustment, the updated first transformation parameter and the second transformation parameter will be output. These new parameters will be used to control the working state of the transformer and ensure that the equipment operates within the normal temperature range.

[0027] After the first transformer uses the first transformation parameter to transform the input signal of the abnormal transformation path to output a first transformation signal, the second transformer uses the second transformation parameter to transform the first transformation signal to output a second transformation signal.

[0028] In one embodiment, the first transformer will use the first transformation parameter to transform the input signal of the abnormal transformation path. The input signal is usually a current or voltage signal from the power grid or other power supply. The first transformer will perform a first transformation on the signal according to the characteristics of the input signal (such as voltage, current) and the set first transformation parameter (such as output voltage, current or voltage ratio, etc.), thereby outputting a first transformation signal; then, the second transformer will receive the first transformation signal output by the first transformer, and perform further transformation operations according to the second transformation parameter. The second transformation parameter is usually adjusted according to the load requirements of the abnormal transformation path (such as increasing the voltage ratio, adjusting the output current, etc.). The second transformer will use these new transformation parameters to perform a secondary transformation on the first transformation signal, and finally output a second transformation signal to ensure that the load can obtain a stable and appropriate voltage or power supply. Through this two-stage transformation process, it is possible to effectively cope with changes in abnormal loads, optimize voltage and power distribution, and ensure that the equipment operates in a stable and safe state.

[0029] Further, if Figure 2 As shown, the present application provides that after outputting the second voltage transformation signal, the method includes: Acquire a signal receiving end of the first transformer; establish a first transmission link based on the first transformer and the signal receiving end; establish a second transmission link based on the first transformer, the second transformer and the signal receiving end; the multiple transformation paths transmit signals through the first transmission link or the second transmission link.

[0030] Preferably, first, determine and obtain the signal receiving end of the first transformer. The signal receiving end is usually a device connected to the transformer output signal, such as a multi-protocol communication module (supporting CAN bus, RS-485 and industrial Ethernet), which receives the signal output by the transformer; then, according to the positional relationship between the first transformer and the signal receiving end, a communication protocol such as Modbus RTU over RS-485 is used to establish a first transmission link. This link connects the output end of the first transformer and the signal receiving end, and is responsible for transmitting the electrical signal output by the transformer to the receiving end; then, according to the relationship between the first transformer, the second transformer and the signal receiving end, establish a second transmission link. This link includes the connection between the first transformer and the second transformer, and is connected to the signal receiving end. The second transmission link is not only responsible for signal transmission, but also involves secondary conversion of the signal to adapt to load requirements; finally, according to different load requirements, it is possible to choose to send the signal through the first transmission link or the second transmission link, and the signals of multiple transformer paths will be transmitted according to the selection of these links to ensure the signal transmission efficiency and stable power supply of the load.

[0031] Further, the present application provides that the plurality of voltage transformation paths transmit signals through the first transmission link, the method comprising: Determine the transformation parameters corresponding to the non-abnormal transformation path; the first transformer uses the transformation parameters corresponding to the non-abnormal transformation path to perform transformation, output a transformation signal, and send the transformation signal from the output end of the first transformer to the signal receiving end.

[0032] Optionally, for each non-abnormal transformation path (less than or equal to the preset load index), the corresponding transformation parameters are obtained and determined, including input voltage, output voltage, voltage ratio, etc., which are standard working values ​​under normal load conditions; once the transformation parameters corresponding to the non-abnormal transformation path are determined, the first transformer will use these parameters to transform the input signal, and in this process, it will be ensured that the working state of the first transformer is consistent with these standard transformation parameters, thereby ensuring the stability and efficiency of the transformation process; the first transformer converts the input signal into a transformation signal by using the determined transformation parameters, and the voltage and current values ​​of the transformation signal will meet the current requirements and can be used smoothly in subsequent links; after the transformation signal is output, the signal will be sent to the signal receiving end through the output end of the first transformer, ensuring that the transformed signal can be effectively received and used to drive the load or perform other operations. In this way, the load of the non-abnormal transformation path can be kept running under standard transformation parameters, ensuring the stability and efficiency of the system.

[0033] Further, the present application provides that the plurality of voltage transformation paths transmit signals through the second transmission link, the method comprising: The first transformer uses the first transformation parameter to transform the input signal of the abnormal transformation path, and after outputting the first transformation signal, the second transformer receives the first transformation signal, and uses the second transformation parameter to transform the first transformation signal to output a second transformation signal, and the output end of the second transformer sends the second transformation signal to the signal receiving end.

[0034] Optionally, after the first transformer receives the input signal from the abnormal transformation path, according to the first transformation parameter (such as input voltage, voltage ratio, etc.), the first transformer transforms the input signal for the first time and converts it into a first transformation signal. This process is based on the load requirements and the adjustment requirements of the transformation path. The signal after transformation adapts to the requirements of the abnormal load path. The first transformation signal will be sent to the second transformer and enter the subsequent transformation processing process; then, the second transformer receives the first transformation signal from the output end of the first transformer and further transforms the signal according to the second transformation parameter. This process includes adjusting the voltage or current to meet the load requirements or adapt to different working conditions. The second transformation parameter is usually adjusted according to the abnormal situation of the load to ensure that the second transformation signal meets the actual needs; after the transformation processing of the second transformer, the second transformation signal already has parameters to adapt to the subsequent load, and the second transformation signal usually has higher voltage, more suitable current and other parameters to meet the load requirements; finally, the second transformation signal is sent to the signal receiving end through the output end of the second transformer for driving the load or performing other operations. Through this process, the first and second transformers achieve effective regulation of abnormal load paths through two-stage transformation, ensuring stable operation of the system while avoiding overload or damage to equipment caused by abnormal loads.

[0035] Furthermore, the present application provides that the multiple voltage transformation paths transmit signals through the first transmission link or the second transmission link, and the method further includes: Calculate the first transmission loss data corresponding to the first transmission link; calculate the second transmission loss data corresponding to the second transmission link; perform signal loss compensation on the voltage transformation path through the first transmission link according to the first transmission loss data, and perform signal loss compensation on the voltage transformation path through the second transmission link according to the second transmission loss data.

[0036] Optionally, during the signal transmission process, the transmission loss of the first transmission link is evaluated. The transmission loss is usually determined by the energy loss caused by resistance, device performance, transmission medium and other factors during the signal transmission on the link. and link impedance Input to the transmission loss calculation formula Calculate the first transmission loss data of the first transmission link , this first transmission loss data will be used for subsequent loss compensation, and then the same method will be used to calculate the second transmission loss data corresponding to the second transmission link; after obtaining the transmission loss data of the first and second transmission links, signal loss compensation will be performed for each transformer path. According to the first transmission loss data, signal loss compensation will be performed on the transformer path passing through the first transmission link. Usually, the strength of the signal passing through the transformer path is added to the first transmission loss data to ensure that the quality of the signal will not decrease after transmission; similarly, according to the second transmission loss data, corresponding signal loss compensation will be performed on the transformer path passing through the second transmission link, and the compensation method is the same as described above. By performing signal loss compensation on the two links, it can be ensured that there will not be excessive attenuation during signal transmission, thereby improving the stability and reliability of the signal and ensuring that the load on the transformer path can obtain sufficient and stable voltage or power supply.

[0037] In summary, the embodiments of the present application have at least the following technical effects: The embodiment of the present application first constructs a transformer module, wherein the transformer module includes a first transformer and a second transformer, wherein the first transformer is a main transformer and the second transformer is a secondary transformer; multiple transformation paths of the first transformer are obtained, operation monitoring is performed on the multiple transformation paths respectively, and multiple groups of operation monitoring data sets are output; load abnormality is identified for the multiple groups of operation monitoring data sets, and abnormal transformation paths that are greater than a preset load index are determined; transformation parameters corresponding to the abnormal transformation paths are determined, the transformation parameters are adaptively separated based on the preset load index, and a first transformation parameter and a second transformation parameter are output; after the first transformer uses the first transformation parameter to transform the input signal of the abnormal transformation path and outputs a first transformation signal, the second transformer uses the second transformation parameter to transform the first transformation signal and outputs a second transformation signal. These technical effects jointly solve the technical problem that the transformer cannot dynamically optimize the energy efficiency distribution under load fluctuations or abnormal operating conditions during power supply, resulting in aggravated local overload losses and reduced system operation stability. It realizes two-stage adaptive power distribution based on path-level load identification, realizes dynamic migration and coordinated transformation of abnormal loads through parameter decoupling, and significantly improves the fault tolerance and energy efficiency balance of multi-path transformation.
