[0052] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] Figure 1 1 is a flow chart of a control method for a transformer provided by an embodiment of the present invention. The control method is applied to a control system of the transformer, and the control system may include a processor module, a rectifier module and a monitoring module, and the monitoring module includes a three-phase acquisition unit and a temperature acquisition unit. The three-phase acquisition unit and the temperature acquisition unit may be connected to the processor module via a 485 line. The 485 line can detect a voltage as low as 200mV with high sensitivity and can be used for communication in long-distance and high-noise environments. In an ideal environment, the transmission distance of the 485 bus can reach 1200 meters. The processor module may be a computer. The control method may include the following steps 101 to 105.

[0054] 101. Acquire three-phase information of the transformer collected by a three-phase collection unit and an outer surface temperature of the transformer collected by a temperature collection unit.

[0055] In this step, the three-phase acquisition unit may include three phase wires and one neutral wire.

[0056] The included angle between any two of the three phase lines is 120 degrees, and the three phase lines are all connected to the transformer signal.

[0057] The acquiring the three-phase information of the transformer collected by the three-phase collection unit may include:

[0058] The three-phase current information and / or three-phase voltage information of the transformer collected by the three-phase collection unit through the three phase lines are obtained. Through the above acquisition method, more accurate three-phase current information and / or three-phase voltage information can be obtained, which is conducive to more accurate determination of the operating state of the transformer in the subsequent process.

[0059] The temperature acquisition unit is a thermocouple temperature sensor, and the thermocouple temperature sensor is in contact with the outer surface of the transformer.

[0060] Acquiring the outer surface temperature of the transformer collected by the temperature collection unit may include:

[0061] The outer surface temperature of the transformer collected by the thermocouple temperature sensor is obtained. Through the above acquisition method, the outer surface temperature of the transformer with higher accuracy can be obtained, which is conducive to more accurate determination of the operating state of the transformer in the future.

[0062] Generally, the three-phase current information and three-phase voltage information can be converted into low voltage or small current signals suitable for subsequent processing, amplified, filtered and conditioned by analog circuits, and then sampled, calculated and stored by digital circuits to obtain data that can be recognized and processed by the processor module.

[0063] 102. Detect the operating status of the transformer based on three-phase information and external surface temperature.

[0064] A pre-trained emergency response model unit is established in the processor module.

[0065] The detecting the operating state of the transformer based on the three-phase information and the outer surface temperature may include:

[0066] The three-phase information and the outer surface temperature are input into the emergency processing model unit, and the operating state of the transformer is detected by the emergency processing model unit.

[0067] The above-mentioned method of detecting the operating status of the transformer reduces the requirements on the skills of technicians, alleviates the work pressure of technicians, and has high detection efficiency and detection accuracy.

[0068] 103. When the operating state is an abnormal state, determine an adjustment signal corresponding to the abnormal state.

[0069] In this step, when the operating state is an abnormal state, determining the adjustment signal corresponding to the abnormal state may include:

[0070] By comparing the abnormal state with a pre-established correspondence between the abnormal state and the solution through the emergency processing model unit, a solution corresponding to the abnormal state is determined;

[0071] An adjustment signal is generated based on a solution corresponding to the abnormal state.

[0072] The corresponding relationship includes a variety of abnormal states and solutions corresponding to the abnormal states. Therefore, when comparing the determined abnormal state with the corresponding relationship, if the abnormal state exists in the corresponding relationship, the solution corresponding to the abnormal state can be found, which has high efficiency and accuracy, reduces the requirements for technical personnel skills, and is conducive to saving the cost of training technical personnel skills.

[0073] 104. Input the adjustment signal to the rectifier module to obtain a rectified signal.

[0074] In this step, the rectifier module may include a diode and a filter. The rectifier module may convert the regulation signal into a DC signal through a diode, and then filter the DC signal through a filter to reduce noise and interference in the DC signal, and obtain a smooth rectified signal. By converting the regulation signal into a DC signal through a diode, AC can be converted into DC to meet the use requirements of the transformer, and the DC signal is filtered through a filter to obtain a smooth rectified signal, and the stability of the rectified signal can also be improved. The power supply of the processor module can be connected to the rectifier module to ensure the stability of the power supply of the rectifier module.

[0075] 105. Input the rectified signal to the transformer to control the transformer.

[0076] In this embodiment, the three-phase information of the transformer collected by the three-phase collection unit and the outer surface temperature of the transformer collected by the temperature collection unit are obtained, and the operating state of the transformer is detected based on the three-phase information and the outer surface temperature. When the operating state is an abnormal state, an adjustment signal corresponding to the abnormal state is determined, and the adjustment signal is input into the rectifier module to obtain a rectifier signal, and the rectifier signal is input into the transformer to control the transformer, thereby realizing real-time monitoring of the operating state of the transformer, and quickly detecting the abnormal state and adjusting and controlling the transformer, which is very efficient.

[0077] In one embodiment of the present specification, the emergency response model unit is pre-trained in the following manner:

[0078] Remove abnormal data and duplicate data from the sample outer surface temperature and sample three-phase information of the transformer collected in advance to obtain usable sample data;

[0079] Inputting the available sample data into the emergency processing model unit, training the emergency processing model unit, and establishing a corresponding relationship between abnormal states and solutions in the emergency processing model unit;

[0080] Input the pre-collected transformer outer surface temperature test data and three-phase information test data into the trained emergency treatment model unit to obtain the transformer operation test status;

[0081] Compare the actual operating state of the transformer corresponding to the outer surface temperature test data and the three-phase information test data with the operating test state to obtain a comparison result;

[0082] When the comparison result indicates that the actual operation state is consistent with the operation test state, a trained emergency processing model unit is obtained;

[0083] When the comparison result indicates that the actual operation state and the operation test state are inconsistent, the process returns to the step of inputting the available sample data into the emergency processing model unit.

[0084] In this embodiment, abnormal data generally refers to data with values ​​that are too large or too small. For example, the mean and standard deviation of the data are used to determine the normal range of the data. It is generally believed that data points that exceed the mean ± 2 times the standard deviation are abnormal values; for another example, a density-based clustering algorithm can identify points in sparse areas as abnormal values.

[0085] By removing the abnormal data and duplicate data from the pre-collected sample outer surface temperature and sample three-phase information of the transformer, available sample data is obtained, which reduces the amount of invalid data and is conducive to improving the training efficiency and accuracy of the emergency treatment model unit. The above-mentioned method of training the emergency treatment model unit can enable the emergency treatment model unit after training to accurately detect the operating status of the transformer and determine the correct solution.

[0086] The emergency response model unit can be regarded as a neural network model. There are many types of neural network models that can be used, such as artificial neural network (ANN), support vector machine (SVM), deep neural network (DNN), convolutional neural network (CNN), deep belief network (DBN), etc.

[0087] In one embodiment of the present specification, a PID control unit is pre-established in the processor module, and before the adjustment signal is input to the rectifier module, the following may also be included:

[0088] Preprocessing the adjustment signal by the PID control unit;

[0089] The pre-processing may include at least one of the following:

[0090] Converting the regulated signal into a frequency domain signal;

[0091] Performing filtering processing on the adjustment signal;

[0092] Performing enhancement processing on the adjustment signal;

[0093] compressing the adjustment signal to reduce the amount of the adjustment signal;

[0094] The formula of the PID control unit can be shown as follows:

[0095] P=kp*e(t)+Ki∫e(t)+Kd(t) / dt(1).

[0096] In formula (1), P is the output value of PID, Ki is the integral coefficient, Kd is the differential coefficient, e(t) is the feedback error, t is the time, and kp is the proportional coefficient.

[0097] In this embodiment, the adjustment signal is converted into a frequency domain signal, which facilitates easier analysis of the frequency characteristics of the adjustment signal and helps to make a more effective control strategy. Filtering the adjustment signal can effectively reduce the interference of noise on the control system and improve the stability and response accuracy of the system. Filtering helps to reduce errors caused by noise and make the control system more accurate and reliable. Enhancement processing of the adjustment signal can improve the response speed of the system and make the system respond to the adjustment signal more quickly. Compression processing of the adjustment signal can reduce the number of the adjustment signal and improve processing efficiency.

[0098] In formula (1), the proportion can quickly reflect the deviation, thereby reducing the deviation. The smaller the proportional coefficient kp, the smaller the control effect and the slower the system response. On the contrary, the larger the proportional coefficient kp, the stronger the control effect and the faster the system response. Integration is used to eliminate static error and improve the system's degree of non-difference. It depends on the integral time constant Ki. The larger the Ki, the weaker the integral effect, and vice versa. Differentiation is used to reflect the changing trend of the deviation signal and can introduce an effective early correction signal into the system before the value of the deviation signal becomes too large, thereby speeding up the system's action speed and reducing the adjustment time.

[0099] In some other embodiments of the present specification, the three-phase information of the transformer collected by the three-phase acquisition unit and the outer surface temperature of the transformer collected by the temperature acquisition unit can also be first input into the PID control unit for preprocessing. The preprocessing process can refer to the above-mentioned preprocessing process. After preprocessing, the operating status of the transformer is detected based on the preprocessed three-phase information and the outer surface temperature, which is also conducive to improving the stability and response accuracy of the system.

[0100] In one embodiment of the present specification, when the abnormal state is transformer load, the solution may include reducing the load of the transformer or increasing the input voltage of the transformer;

[0101] When the abnormal state is that the transformer temperature is higher than a preset temperature, the solution may include controlling the transformer to stop operating.

[0102] In this embodiment, when the transformer is loaded, that is, the transformer is in an overloaded operation state, at this time, in order to reduce the load of the transformer, the load of the transformer can be reduced, for example, part of the load can be transferred to other transformers or equipment to reduce the burden of the overloaded transformer, temporarily limit the access of new loads, ensure that the existing load is within the carrying range of the transformer, and adjust the operation strategy, such as staggered power consumption, reduce the load during peak hours, etc. The input voltage of the transformer can also be increased, for example, by changing the tap position of the transformer, adjusting the transformation ratio of the transformer, thereby increasing the output voltage, and by adding reactive compensation equipment, such as a capacitor bank, to improve the power factor of the system, thereby indirectly increasing the voltage level, etc. According to the above solutions, corresponding adjustment signals can be generated.

[0103] When the abnormal state is that the transformer temperature is higher than the preset temperature, the transformer can be stopped to reduce the transformer temperature, and the transformer can be started again when the transformer temperature is lower than the preset temperature. Of course, the operation of the cooling system can also be strengthened to cool the transformer, for example, by increasing the speed of the fan or increasing the amount of water in the water cooling system, or reducing the load of the transformer, etc. According to the above solutions, corresponding adjustment signals can be generated.

[0104] In an embodiment of the present specification, the processor module may further include an alarm unit, and the control method may further include:

[0105] When the operating state is an abnormal state, the alarm unit is controlled to output alarm information.

[0106] In this embodiment, when the operating state is abnormal, the alarm unit is transmitted through an electrical signal so that the alarm unit emits a sound to alert the staff. The alarm unit can be a speaker, a horn, or a buzzer. In addition to alerting the staff by emitting a sound, the current position of each staff member responsible for the transformer maintenance can also be obtained, and the staff member closest to the transformer can be obtained according to the current position, and the information is sent to the terminal device pre-bound by the staff member, thereby improving the efficiency of handling transformer problems and avoiding the problem that the sound cannot be heard when there is no one in the environment where the processor module is located.

[0107] In the above embodiment, it is stated that the temperature acquisition unit is a thermocouple temperature sensor. A thermocouple is composed of two welding wires of different materials, which are welded at the ends and then measure the ambient temperature of the unheated area to accurately determine the temperature of the heating point. It requires two different conductor materials, so it is called a thermocouple. Thermocouples made of different materials are used in different temperature ranges and have different sensitivities. The sensitivity of a thermocouple refers to the change in the output potential difference when the temperature of the heating point changes by 1°C. For most thermocouples supported by metal materials, this value is about 5-40 microvolts / °C.

When the operating state is an abnormal state, it determines a regulation signal corresponding to the abnormal state and inputs the regulation signal to the rectifier module 302.

[0111] The rectifier module 302 rectifies the adjustment signal to obtain a rectified signal, and inputs the rectified signal into the transformer to control the transformer.
