[0039] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying 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.

[0040] As an important part of agriculture, animal husbandry and fishery, the industrialization of fish farming has become an inevitable trend. However, fish farming areas are usually distributed in rural areas, and the power infrastructure is relatively weak. Therefore, the voltage is often low, fluctuating, and unbalanced during peak hours at the power terminals, which poses a serious threat to the stable operation of breeding equipment such as three-phase aerators. Once the voltage is unstable or the power supply is interrupted, it will directly affect the working effect of the breeding equipment, and then affect the quality and benefits of fishery production. Therefore, how to monitor and handle abnormal voltage changes in fish farming areas has become a technical problem that needs to be solved urgently in this field.

[0041] In one embodiment, Figure 1-2 As shown, Figure 1 is a structural diagram of a voltage stabilization and compensation system provided in an embodiment of the present application, Figure 2 The circuit diagram of a voltage stabilization compensation system provided in an embodiment of the present application is shown in FIG. The voltage stabilization compensation system 100 includes a voltage stabilization compensation device 110 , which includes a control module 111 , a data acquisition module 112 and a compensation device 113 , wherein the control module 111 is connected to the data acquisition module 112 and the compensation device 113 .

[0042] For example, Figure 2 As shown, the voltage stabilization and compensation system 100 includes a distribution transformer, a power supply line 120 , a voltage stabilization and compensation device 110 , and a load. The distribution transformer, the voltage stabilization and compensation device 110 , and the load are connected through the power supply line 120 .

[0043] In the embodiment of the present application, the voltage stabilizing and compensating device 110 includes a control module 111, a data acquisition module 112, a compensation device 113 and a reactor. The main function of the reactor is to provide inductance, which has an obstruction effect on alternating current, and this obstruction effect is called reactance.

[0044] The data acquisition module 112 is used to acquire the initial electrical signal of the power supply line 120 in the voltage stabilization and compensation system 100 , and transmit the initial electrical signal to the control module 111 .

[0045] Exemplarily, the data acquisition module 112 may be used for an initial electrical signal in the power supply line 120 , and the initial electrical signal may include, for example, an initial current signal and / or an initial voltage signal.

[0046] In one embodiment, a preset time period can be set according to demand, and the data acquisition module 112 can collect the initial electrical signal of the power supply line 120 once every preset time period, and transmit the initial electrical signal to the control module 111.

[0047] Optionally, the data acquisition module 112 can also be used to collect reactive power in the power supply line 120, so that the control module 111 can understand the current power factor and reactive power demand according to the reactive power, so as to adjust the switching of the voltage stabilization and compensation device in a timely manner. Alternatively, the data acquisition module 112 can also be used to collect the frequency of the power supply line 120 to monitor and control the frequency. Alternatively, the data acquisition module 112 can also be used to monitor and analyze the harmonic content in the power supply line 120.

[0048] The control module 111 is used to monitor the initial electrical signal, and when it is determined that the initial electrical signal is abnormal, send a trigger signal corresponding to the initial electrical signal to the compensation device 113 according to the initial electrical signal.

[0049] In an embodiment of the present application, the control module 111 can receive the initial electrical signal sent by the data acquisition module 112, and then monitor the initial electrical signal. If it is determined that the initial electrical signal is abnormal and needs to be compensated, a corresponding trigger signal can be generated based on the initial electrical signal and the trigger signal can be sent to the compensation device 113.

[0050] The compensation device 113 is used to compensate the initial electrical signal of the power supply line 120 according to the trigger signal to obtain a target electrical signal.

[0051] In one embodiment, when the initial electrical signal includes an initial voltage signal, the compensation device 113 can receive a first trigger signal sent by the control module 111, and generate a capacitive voltage component based on the first trigger signal, and offset the inductive voltage component generated by the power supply line through the capacitive voltage component, thereby compensating the initial voltage signal of the power supply line 120 to obtain a target voltage signal.

[0052] Alternatively, when the initial electrical signal includes an initial current signal, the compensation device 113 can receive a second trigger signal sent by the control module 111, and generate a reactive compensation current according to the second trigger signal, and compensate the initial current signal of the power supply line 120 through the reactive compensation current to obtain a target current signal.

[0053] In an embodiment of the present application, a voltage stabilization and compensation system includes a voltage stabilization and compensation device, and the voltage stabilization and compensation device includes a control module, a data acquisition module and a compensation device, and the control module is connected to the data acquisition module and the compensation device. The data acquisition module is used to collect the initial electrical signal of the power supply line in the voltage stabilization and compensation system, and transmit the initial electrical signal to the control module. The control module is used to monitor the initial electrical signal, and when it is determined that the initial electrical signal is abnormal, send a trigger signal corresponding to the initial electrical signal to the compensation device according to the initial electrical signal. The compensation device is used to compensate the initial electrical signal of the power supply line according to the trigger signal to obtain a target electrical signal. In this way, the compensation device can be dynamically controlled based on the control module to realize dynamic adjustment of the electrical signal in the power supply line, so that the electrical signal in the power supply line is in a good working state, thereby improving the stability and reliability of the voltage stabilization and compensation system.

[0054] On the basis of the above embodiment, the compensation device 113 includes a compensation transformer, the initial electrical signal includes an initial voltage signal, and the trigger signal includes a first trigger signal.

[0055] The compensation transformer is used to generate a capacitive voltage component according to the first trigger signal. The capacitive voltage component is used to offset the inductive voltage component generated by the power supply line to compensate the initial voltage signal to obtain a target voltage signal.

[0056] In the present application embodiment, Figure 2 As shown, the compensation transformer can generate a dynamically trackable capacitive voltage component in response to the first trigger signal sent by the control module 111, and offset the inductive voltage component generated by the power supply line through the capacitive voltage component, thereby compensating the initial voltage signal of the power supply line 120 to obtain the target voltage signal.

[0057] Optionally, the voltage stabilizing and compensating device 110 also includes a capacitor. The compensation transformer is mainly used to compensate for reactive power to improve the power factor and stability of the voltage stabilizing and compensating system. Its working principle is based on the law of induction and the magnetic coupling phenomenon, and the direction and magnitude of reactive power are adjusted by changing the voltage and current phases in the circuit. The compensation transformer is composed of two or more coils, which are wound on a common iron core, including a main coil and a compensation coil. The main coil is connected to the load of the voltage stabilizing and compensating system, and the compensation coil is connected to the capacitor.

[0058] In one embodiment, referring to Figure 3-4 , Figure 3 is a schematic diagram of a power supply system provided in an embodiment of the present application, Figure 4 Schematic diagram of a vector relationship of a power supply system provided in an embodiment of the present application. Figure 3 As shown in Figure 1, a traditional power supply system usually includes a distribution transformer, a power supply line, and a load. The vector relationship in the power supply system can be expressed as Figure 4 As shown, U 0 is the output voltage of the distribution transformer, U e is the inlet voltage of the distribution transformer, U xr is the resistive voltage component of the power supply line, U xl is the inductive voltage component of the power supply line (because there will be a certain line impedance when the power supply line is long, the longer the power supply line, the greater the line impedance, and the line impedance can include: the resistive component of the impedance and the inductive component of the impedance). When the voltage drop of the power supply line is large, it will cause U e Much smaller than U 0 , which in turn causes the user's power voltage to be too low.

[0059] Reference Figure 5 , Figure 5 is a schematic diagram of another vector relationship of a power supply system provided in an embodiment of the present application. There are currently two traditional processing methods for the above problem: the first method is to set a voltage regulating device (such as an adjustable transformer tap) to increase the user-side voltage. The vector relationship of the power supply system after the voltage regulating device is set can be as follows: Figure 5 As shown, U t The first method is to increase the voltage. However, this method will increase the current in the power supply line when increasing the voltage at the user end, increase the loss of the power supply line, and cause excessive fluctuations in the power grid, affecting the reliability of the equipment. The second method is to use parallel compensation to increase the voltage, but this method has a limited range when increasing the voltage at the user end and cannot meet the needs of actual use.

[0060] In the present application, refer to Figure 6 , Figure 6 FIG. 1 is a schematic diagram of another vector relationship of a power supply system provided in an embodiment of the present application. Figure 6As shown, when the voltage signal in the power supply line is compensated by the voltage stabilization compensation system in the embodiment of the present application, the inductive voltage component generated by the power supply line is offset by generating a capacitive voltage component, so that U e Close to U 0 This can meet the voltage requirements of the user end, so that the current of the power supply line can be reduced when compensating the voltage, reducing line losses and keeping the distribution transformer end at a higher power factor.

[0061] On the basis of the above embodiment, the compensation device 113 includes a current compensator, the initial electrical signal includes an initial current signal, and the trigger signal includes a second trigger signal.

[0062] The current compensator is used to generate a reactive compensation current according to the second trigger signal. The reactive compensation current is used to compensate the initial current signal to obtain a target current signal.

[0063] In one embodiment, Figure 2 As shown, the current compensator includes an inverter in which an insulated-gate bipolar transistor (IGBT) is provided. The IGBT can generate a reactive compensation current in response to a second trigger signal sent by the control module 111, and compensate the initial current signal of the power supply line 120 by the reactive compensation current to obtain a target current signal.

[0064] In an embodiment of the present application, a current compensator is used to generate a reactive compensation current according to a second trigger signal, and to compensate an initial current signal by the reactive compensation current to obtain a target current signal, thereby being able to dynamically adjust the current in the power supply line, putting the power supply line in a good working condition, and improving the stability and reliability of the voltage stabilization and compensation system.

[0065] On the basis of the above embodiment, the voltage stabilizing and compensating device 110 further includes an alarm module 114 , and the control module 111 is connected to the alarm module 114 .

[0066] Optionally, the alarm module 114 can be arranged locally in the voltage stabilizing and compensating device 110 and connected to the control module 111 by wire, so as to communicate with the control module 111. Alternatively, the alarm module 114 can also be a portable terminal device, connected to the control module 111 wirelessly, so as to communicate with the control module 111.

[0067] The control module 111 is further configured to transmit the initial electrical signal to the alarm module 114 .

[0068] In one embodiment, after receiving the initial electrical signal sent by the data acquisition module 112 , the control module 111 may transmit the initial electrical signal to the alarm module 114 .

[0069] The alarm module 114 is used to generate a first alarm message when the initial electrical signal exceeds a first preset interval.

[0070] The first alarm information is used to indicate that there is an abnormality in the initial electrical signal.

[0071] In one embodiment, if the initial electrical signal is smaller than the lower limit of the first preset interval, it means that the initial electrical signal needs to be compensated; if the initial electrical signal is larger than the upper limit of the first preset interval, it means that the initial electrical signal is too large. In order to prevent damage to the power equipment in the power supply line, a control instruction can be generated to instruct to disconnect the power supply line.

[0072] Optionally, when the initial electrical signal is smaller than the lower limit of the first preset interval, the first alarm information can be used to indicate that the initial electrical signal in the power supply line is too small and needs to be compensated; when the initial electrical signal is larger than the upper limit of the first preset interval, the first alarm information can be used to indicate that the initial electrical signal in the power supply line is too large.

[0073] In the embodiment of the present application, the voltage stabilizing and compensating device 110 further includes an alarm module 114, and the control module 111 is connected to the alarm module 114. The control module 111 is used to transmit the initial electrical signal to the alarm module 114. The alarm module 114 is used to generate a first alarm message to indicate that the initial electrical signal is abnormal when the initial electrical signal exceeds the first preset interval. In this way, the relevant operating personnel can be reminded when the initial electrical signal is abnormal, so as to take timely processing measures, further improving the stability and reliability of the voltage stabilizing and compensating system.

[0074] On the basis of the above embodiment, the control module 111 is used to transmit the target electrical signal to the alarm module 114 .

[0075] In one embodiment, after the control module 111 compensates the initial electrical signal to obtain the target electrical signal, the target electrical signal may be sent to the alarm module 114 .

[0076] The alarm module 114 is further configured to generate a second alarm message when the target electrical signal exceeds a second preset interval.

[0077] The second alarm information is used to indicate that there is an abnormality in the target electrical signal in the power supply line.

[0078] In one embodiment, if the target electrical signal is smaller than the lower limit of the second preset interval, it means that the electrical signal in the power supply circuit is still low after the initial electrical signal is compensated by the voltage stabilization compensation device; if the target electrical signal is larger than the upper limit of the second preset interval, it means that the target electrical signal is larger.

[0079] Optionally, when the target electrical signal is less than the lower limit of the second preset interval, the second alarm information can be used to indicate that the electrical signal in the power supply line is still low after compensation; when the target electrical signal is greater than the upper limit of the second preset interval, the second alarm information can be used to indicate that the target electrical signal in the power supply line is large.

[0080] In the embodiment of the present application, the control module 111 is used to transmit the target electrical signal to the alarm module 114. The alarm module 114 is also used to generate a second alarm message when the target electrical signal exceeds the second preset interval to indicate that the target electrical signal in the power supply line is abnormal. In this way, when the target electrical signal after compensation is abnormal, the relevant operating personnel can be reminded so that processing measures can be taken in time, further improving the stability and reliability of the voltage stabilization compensation system.

[0081] On the basis of the above embodiment, the voltage stabilizing and compensating device 110 further includes a first switch.

[0082] For example, Figure 2 The switches at 1KM and 3KM shown in the figure are the first switches. When the first switch is disconnected, the power supply line can be disconnected.

[0083] Optionally, when the initial electrical signal is greater than an upper limit of the first preset interval, the power supply line may be disconnected by disconnecting the first switch.

[0084] The control module 111 is further configured to send a control instruction to the first switch when it is determined according to the initial electrical signal that the power supply line is phase-deficient.

[0085] The control instruction is used to instruct the first switch to be disconnected so as to disconnect the power supply line.

[0086] In one embodiment, the control module 111 can also determine whether the power supply line is missing a phase based on the initial electrical signal, and when it is determined that the power supply line is missing a phase, generate a control instruction and send the control instruction to the first switch to disconnect the first switch, thereby disconnecting the power supply line, further improving the stability and reliability of the voltage stabilization and compensation system.

[0087] On the basis of the above embodiment, the alarm module 114 is further configured to send a prompt message to the control module 111 when the target electrical signal exceeds a third preset interval.

[0088] The prompt information is used to prompt the control module to disconnect the first switch to disconnect the power supply line. The third preset interval is greater than the second preset interval.

[0089] In one embodiment, a third preset interval greater than the second preset interval can be set, and then the target electrical signal is monitored based on the third preset interval. If the target electrical signal is less than the lower limit of the third preset interval, it means that the target electrical signal is too small; if the target electrical signal is greater than the upper limit of the third preset interval, it means that the target electrical signal is too large. When the target electrical signal is too small or too large, it may cause serious damage to the power equipment in the voltage stabilization and compensation system. Therefore, in order to protect the power equipment, a prompt message can be sent to the control module 111. After receiving the prompt message, the control module 111 can generate a control instruction and send the control instruction to the first switch to disconnect the first switch, thereby disconnecting the power supply line, further improving the stability and reliability of the voltage stabilization and compensation system.

[0090] On the basis of the above embodiment, the voltage stabilization and compensation system 100 further includes a second switch, which is arranged on a bypass of the power supply line 120 .

[0091] The second switch is used to short-circuit the voltage stabilizing and compensating device 110 when closed.

[0092] For example, Figure 2 The switch at 2KM shown is the second switch. If the voltage stabilizing and compensating device 110 needs to be temporarily removed for maintenance or overhaul, the voltage stabilizing and compensating device 110 can be short-circuited by closing the second switch, thereby improving the safety of the voltage stabilizing and compensating system.

[0093] It should be noted that when the voltage stabilizing and compensating device 110 is maintained or repaired, in order to further ensure the safety of relevant personnel, the first switch can also be disconnected to completely isolate the power supply and the voltage stabilizing and compensating device to prevent backflow from other power supplies to the working circuit and avoid danger caused by accidental power supply.

[0094] Based on the same inventive concept, the embodiment of the present application also provides a compensation method applied to the voltage stabilization compensation system involved above. The implementation scheme for solving the problem provided by the control method is similar to the implementation scheme recorded in the above control system, so the specific limitations in one or more control method embodiments provided below can refer to the limitations on the control system above, and will not be repeated here.
