[0057] As described in the background technology, in modern power transmission and communication systems, dual-split cables are used as the main transmission medium, and the impedance characteristics of the connection between the two cables have a critical impact on the performance of the entire power supply system. The impedance of a cable is the sum of its resistivity and inductive reactance to AC signals, and usually includes resistance, inductance and capacitance. In an ideal transmission system, the impedance of the two cables should be balanced to achieve maximum power transmission and minimum signal reflection.

[0058] In conventional technology, impedance balancing of a double-split cable is generally performed only based on the cable state of the double-split cable. However, since the double-split cable may be affected by a variety of factors during power transmission, impedance balancing based only on the state may be inaccurate.

[0059] Based on the above reasons, the present invention provides a dual-split cable connection impedance balancing system capable of accurately balancing impedance.

[0060] In one embodiment, Figure 1 As shown, a dual-split cable connection impedance balancing system is provided, the system comprising an impedance detection device 10, a control device 20, and an impedance compensation device 30;

[0061] The impedance detection device 10 is used to perform impedance detection on a first cable and a second cable included in the double-split cable during power transmission of the double-split cable, respectively, to determine a first current impedance corresponding to the first cable and a second current impedance corresponding to the second cable;

[0062] The control device 20 is used to obtain the first current impedance and the second current impedance, and determine the compensation impedance for the second cable based on the impedance difference between the first current impedance and the second current impedance, and determine a target compensation unit that matches the compensation impedance from a plurality of impedance compensation units included in the impedance compensation device;

[0063] The impedance compensation device 30 is used to perform impedance compensation on the second cable by adjusting the electrical parameters of the target compensation unit under the control of the control device 20.

[0064] Among them, a cable is a wire used to transmit power or signals, usually composed of one or more mutually insulated conductors and an outer insulating layer. A double-split cable is composed of two wires in parallel. This structure makes the double-split cable superior to a single wire in electrical performance, with higher transmission capacity and better stability. The impedance detection device 10 refers to a device that can perform impedance detection on the cable. For example, the impedance detection device 10 can detect the voltage and current corresponding to the first cable and the second cable included in the double-split cable in real time, and calculate the first current impedance and the second current impedance corresponding to the first cable and the second cable according to the collected voltage and current, or directly detect the impedance corresponding to the first cable and the second cable. The control device 20 is a device for controlling the actuator and collecting sensor data. Specifically to this application, the control device 20 is the core part of the system, responsible for receiving the first current impedance and the second current impedance from the impedance detection device 10, calculating the required compensation impedance, and controlling the impedance compensation device 30 to adjust the impedance compensation unit 31 to achieve precise adjustment of the impedance.

[0065] The control device 20 mainly includes the following parts:

[0066] Processor: responsible for processing the first current impedance and the second current impedance transmitted by the impedance detection device 10, running the preset impedance calculation and optimization algorithm, and calculating the required compensation impedance. The efficient operation of the processor is the key to ensuring the real-time performance of the system.

[0067] Control circuit: Generates a control signal based on the result of the processor calculation to control the impedance compensation device 30 to adjust the electrical parameters of the target compensation unit to ensure that the system impedance matching reaches the optimal state.

[0068] The impedance compensation device 30 is a device that uses power equipment and circuits to improve system voltage, current, power factor and other characteristics, and can adjust the impedance of the first cable and the second cable to achieve impedance matching and balance. The main task of the impedance compensation device 30 is to compensate the impedance by adjusting the electrical parameters of the target compensation unit.

[0069] The first current impedance refers to the impedance of the first cable at the current moment. The second current impedance refers to the impedance of the second cable at the current moment. The compensation impedance refers to the impedance value used to compensate the second cable. Figure 2 As shown, the impedance compensation unit 31 may include, for example, an inductance unit 311, a capacitance unit 312, and a resistance unit 313, and may perform impedance compensation on the second cable. The target compensation unit refers to the impedance compensation unit 31 determined to match the compensation impedance. The electrical parameter refers to the electrical parameter of the impedance compensation unit 31, and may include, for example, power-on time, frequency, or current magnitude, etc.

[0070] Specifically, in the process of transmitting power through a cable, due to the mismatch problem of the connection impedance of the double-split cable, it is necessary to configure an impedance detection device 10 that can perform impedance detection on the first cable and the second cable respectively, so as to determine the first current impedance corresponding to the first cable and the second current impedance corresponding to the second cable. After that, the control device 20 obtains the first current impedance and the second current impedance, and compares the first current impedance and the second current impedance to obtain the impedance difference, so as to determine the compensation impedance for the second cable. Based on the compensation impedance, a target compensation unit matching the compensation impedance can be determined from the multiple impedance compensation units 31 included in the impedance compensation device 30, and the impedance compensation device 30 can be controlled to adjust the electrical parameters of the target compensation unit, so as to achieve the purpose of impedance compensation for the second cable.

[0071] The above-mentioned double-split cable connection impedance balancing system is configured to respectively perform impedance detection on the first cable and the second cable included in the double-split cable during the process of transmitting power through the double-split cable, and determine the first current impedance corresponding to the first cable and the second current impedance corresponding to the second cable. The impedance detection device can determine the impedance conditions corresponding to the two cables in the double-split cable during the process of transmitting power through the double-split cable, configure the control device to obtain the first current impedance and the second current impedance, and determine the compensation impedance for the second cable based on the impedance difference between the first current impedance and the second current impedance. The compensation impedance for the second cable can be accurately determined based on the specific conditions of the first current impedance and the second current impedance. From the multiple impedance compensation units included in the impedance compensation device, a target compensation unit that matches the compensation impedance can be determined, and impedance compensation can be performed in a targeted manner. The impedance compensation device is configured to perform impedance compensation on the second cable by adjusting the electrical parameters of the target compensation unit under the control of the control device, and can achieve the purpose of accurately matching the balanced impedance.

[0072] In an exemplary embodiment, Figure 3As shown, the impedance detection device 10 includes a signal acquisition module 11, an analog-to-digital conversion module 12, and a data processing module 13; the signal acquisition module 11 is used to perform electrical signal detection on the first cable and the second cable respectively, and determine the first current analog signal and the first voltage analog signal corresponding to the first cable, and the second current analog signal and the second voltage analog signal corresponding to the second cable; the analog-to-digital conversion module 12 is used to perform analog-to-digital conversion on the first current analog signal, the first voltage analog signal, the second current analog signal, and the second voltage analog signal respectively, to obtain the first current digital signal, the second voltage digital signal, the second current digital signal, and the second voltage digital signal; the data processing module 13 is used to perform signal analysis on the first current digital signal and the second voltage digital signal, and the second current digital signal and the second voltage digital signal respectively, to determine the first current impedance corresponding to the first cable and the second current impedance corresponding to the second cable.

[0073] Among them, the first current analog signal refers to the analog signal corresponding to the current of the first cable at the current moment. The second current analog signal refers to the analog signal corresponding to the current of the second cable at the current moment. The first voltage analog signal refers to the analog signal corresponding to the voltage of the first cable at the current moment. The second voltage analog signal refers to the analog signal corresponding to the voltage of the second cable at the current moment. The first current digital signal refers to the digital signal corresponding to the current of the first cable at the current moment. The second current digital signal refers to the digital signal corresponding to the current of the second cable at the current moment. The first voltage digital signal refers to the digital signal corresponding to the voltage of the first cable at the current moment. The second voltage digital signal refers to the digital signal corresponding to the voltage of the second cable at the current moment.

[0074] Specifically, in the process of determining the first current impedance and the second current impedance, it is necessary to firstly perform electrical signal detection on the first cable and the second cable respectively through the signal acquisition module 11 to determine the first current analog signal and the first voltage analog signal corresponding to the first cable, and the second current analog signal and the second voltage analog signal corresponding to the second cable. In order to facilitate the subsequent data processing, it is also necessary to perform analog-to-digital conversion on the above analog signals through the analog-to-digital conversion module 12 to obtain the first current digital signal, the second voltage digital signal, the second current digital signal and the second voltage digital signal. After that, the above digital signals can be analyzed by the data processing module 13 to determine the first current impedance corresponding to the first cable and the second current impedance corresponding to the second cable. Exemplarily, the signal acquisition module 11 may include a current sensor and a voltage sensor to perform electrical signal detection on the first cable and the second cable respectively.

[0075] In this embodiment, the impedance detection device 10 includes a signal acquisition module 11, an analog-to-digital conversion module 12, and a data processing module 13, which can realize accurate detection of the impedances corresponding to the first cable and the second cable respectively.

[0076] In an exemplary embodiment, Figure 2 As shown, the impedance compensation unit 31 includes an inductance unit 311, a capacitance unit 312 and a resistance unit 313; when the compensation impedance includes a compensation resistance, the control device 20 determines that the target compensation unit includes the resistance unit 313; when the compensation impedance includes a compensation reactance, the control device 20 determines that the target compensation unit includes at least one of the inductance unit 311 or the capacitance unit 312.

[0077] Among them, the inductance unit 311, also known as an inductor or a coil, is a component that can store magnetic field energy. It is usually made of an insulated wire wound on an insulating frame. The capacitance unit 312, also known as a capacitor, is a component that can store electric field energy. It consists of two or more mutually insulated metal plates, and a dielectric is filled between the plates. The resistance unit 313, also known as a resistor, is a component that hinders the current. It is usually made of a conductor material, and its resistance value depends on the material, length, cross-sectional area and temperature of the conductor.

[0078] Specifically, the process of compensating impedance mainly includes compensating resistance and reactance, the resistance corresponds to the resistance unit 313, and the reactance corresponds to the capacitance unit 312 and the inductance unit 311. That is, when the compensation impedance includes the compensation resistance, the control device 20 can determine that the target compensation unit includes the resistance unit 313. When the compensation impedance includes the compensation reactance, the control device 20 determines that the target compensation unit includes at least one of the inductance unit 311 or the capacitance unit 312.

[0079] In this embodiment, the control device 20 can determine that the target compensation unit is at least one of the resistance unit 313, the inductance unit 311 or the capacitance unit 312 according to the specific compensation situation of the compensation impedance, and can perform impedance compensation on the second cable in a targeted manner, thereby ensuring the accuracy of the impedance compensation process.

[0080] In an exemplary embodiment, the control device 20 is further used to: for the second cable after impedance compensation, obtain an updated impedance of the second cable; and determine an updated compensated impedance of the second cable based on the updated impedance and the first current impedance.

[0081] The updated impedance refers to the updated impedance of the second cable after impedance compensation, and the updated compensated impedance refers to the compensated impedance corresponding to the updated impedance.

[0082] Specifically, in order to ensure that the system is always in the best working state, the compensation impedance can be adjusted in real time according to the change of the cable operation state, that is, after the impedance compensation is performed on the second cable, the control device 20 can also obtain the updated impedance of the second cable for the second cable after impedance compensation, determine the updated compensation impedance of the second cable based on the updated impedance difference between the updated impedance and the first current impedance, and determine the updated target compensation unit that matches the updated compensation impedance from the multiple impedance compensation units 31 included in the impedance compensation device 30, and control the impedance compensation device 30 to adjust the electrical parameters of the updated target compensation unit to perform impedance compensation on the second cable again. It can be understood that the above steps can be repeated to ensure that the system is always in the best working state.

[0083] In an exemplary embodiment, Figure 4 As shown, the dual-split cable connection impedance balancing system further includes an information storage device 40; the information storage device 40 is used to store the first current impedance, the second current impedance and the compensation impedance.

[0084] Specifically, the dual-split cable connection impedance balancing system also includes an information storage device 40 that can store the first current impedance, the second current impedance and the compensation impedance, so as to store the information involved in the dual-split cable connection impedance balancing process to facilitate subsequent information tracing and ensure the stability of the dual-split cable connection impedance balancing process.

[0085] In an exemplary embodiment, Figure 5 As shown, the dual-split cable connection impedance balancing system also includes an alarm device 50; the alarm device 50 is used to monitor the first current impedance and the second current impedance, and output an alarm signal when at least one of the first current impedance and the second current impedance reaches an impedance threshold.

[0086] The impedance threshold refers to a pre-established threshold for the impedance at the first cable or the second cable.

[0087] Specifically, the alarm device 50 can be configured to monitor the first current impedance and the second current impedance in real time. If at least one of the first current impedance and the second current impedance reaches the impedance threshold, it indicates that the impedance of the double-split cable is strong and intervention is required, and an alarm signal needs to be fed back.

[0088] In this embodiment, the configuration can monitor the first current impedance and the second current impedance. When at least one of the first current impedance and the second current impedance reaches the impedance threshold, the alarm device 50 outputs an alarm signal, which can avoid cable damage caused by excessively high current impedance and ensure the normal impedance balance of the double-split cable connection.

[0089] In an exemplary embodiment, Figure 6 As shown, the dual-split cable connection impedance balancing system also includes a power supply device 60; the power supply device 60 is connected to the impedance detection device 10, the control device 20, and the impedance compensation device 30; the power supply device 60 is used to supply power to the impedance detection device 10, the control device 20, and the impedance compensation device 30.

[0090] The power supply device 60 may refer to a device that can supply power.

[0091] Specifically, in this embodiment, the power supply device 60 is connected to the impedance detection device 10 , the control device 20 , and the impedance compensation device 30 , and can provide power to the impedance detection device 10 , the control device 20 , and the impedance compensation device 30 .

[0092] In this embodiment, the power supply device 60 is configured to ensure the continuous operation of the dual-split cable connection impedance balancing system.

[0093] In an exemplary embodiment, Figure 7 As shown, the dual-split cable connection impedance balancing system further includes a display device 70 ; the display device 70 is connected to the impedance detection device 10 ; the display device 70 is used to obtain and display the first current impedance and the second current impedance from the impedance detection device 10 .

[0094] The display device 70 refers to a device having a display screen and capable of displaying information.

[0095] Specifically, in order to facilitate the technicians to timely understand the specific situation of the impedance in the double-split cable, a display device 70 may be configured, and the display device 70 may obtain and display the first current impedance and the second current impedance from the impedance detection device.

[0096] In this embodiment, a device with a display screen that can display information is configured to facilitate technicians to promptly understand the specific situation of the impedance in the double-split cable.

[0097] In an exemplary embodiment, Figure 8 As shown, a dual-split cable connection impedance balancing method is also provided, the method comprising:

[0098] Step S802, in the process of transmitting power by the dual-split cables, obtaining a first current impedance corresponding to the first cable and a second current impedance corresponding to the second cable;

[0099] Step S804, determining a compensation impedance for the second cable based on the first current impedance and the second current impedance and based on an impedance difference between the first current impedance and the second current impedance;

[0100] Step S806, determining a target compensation unit that matches the compensation impedance from a plurality of impedance compensation units included in the impedance compensation device;

[0101] Step S808: Control the impedance compensation device to perform impedance compensation on the second cable by adjusting the electrical parameters of the target unit.

[0102] Specifically, in the process of transmitting power by a double-split cable, since there is a mismatch in impedance between the first cable and the second cable, a first current impedance corresponding to the first cable and a second current impedance corresponding to the second cable can be obtained, and the impedance difference between the first current impedance and the second current impedance can be compared to obtain the impedance difference, thereby determining the compensation impedance for the second cable, and then based on the compensation impedance, a target compensation unit matching the compensation impedance can be determined from a plurality of impedance compensation units included in the impedance compensation device, and the impedance compensation device can be controlled to adjust the electrical parameters of the target compensation unit, thereby achieving the purpose of impedance compensation for the second cable.

[0103] In a specific embodiment, a dual-split cable connection impedance balancing system is provided, which can detect the electrical parameters of the dual-split cable in real time and adjust the impedance through an accurate compensation mechanism to ensure the stability and transmission efficiency of the system. The system automatically adjusts the impedance of the second cable in the dual-split cable by integrating an impedance detection device, an impedance compensation device and a control device, and ensures continuous optimization of the compensation effect through a feedback mechanism.

[0132] Specific operation method:

[0133] This embodiment provides a dual-split cable connection impedance balancing control device, which aims to optimize the impedance matching of the dual-split cable connection impedance and improve the performance of the power transmission and communication system. The device improves the transmission efficiency and stability of the system by automatically and in real time monitoring and dynamically adjusting the impedance value. This article describes in detail the functions, installation steps, operation process of each module and the technical advantages of the device.

[0134] The basic components of the device:

[0135] The device mainly includes three modules: impedance detection equipment, impedance compensation equipment, and control equipment. Each module works together to achieve impedance balance adjustment of the double-split cable connection impedance. The functions, composition and synergy of these modules in the whole system will be described in detail below.

[0136] System installation and hardware connection:

[0137] Installation of impedance detection equipment:

[0138] The impedance detection device is the front-end device of the system, responsible for real-time monitoring of the voltage and current of the first cable and the second cable and calculating the impedance value. Its main components include voltage sensor, current sensor, analog-to-digital converter (ADC) and impedance calculation unit.

[0139] Voltage sensor installation:

[0140] Install the voltage sensor on both sides of the first cable and the second cable, and directly connect the two ends of the cable to ensure that the voltage signals of the first cable and the second cable can be captured. You can choose a high-precision voltage sensor or voltage transformer to ensure measurement accuracy.

[0141] An appropriate sensor fixing method is selected according to the structures of the first cable and the second cable to ensure that the sensor will not be displaced or loosened during actual use.

[0142] Current sensor installation:

[0143] Current sensors (such as Hall effect sensors or current transformers) should be installed on the cables of the first and second cables to ensure that the current changes in the cables can be continuously monitored. Hall effect sensors are an ideal non-contact measurement method that can monitor the current flow in the cables in real time to avoid damaging the cables themselves.

[0144] The physical contact or proximity of the current sensor to the cable needs to remain stable to avoid signal fluctuations caused by loose mounting.

[0145] Analog-to-Digital Converter (ADC) and Data Processing:

[0146] The analog voltage and current signals obtained by the sensor are converted into digital signals through an analog-to-digital converter (ADC) for subsequent processing. The analog-to-digital converter needs to be reliably connected to the sensor to ensure that the signal is not distorted.

[0147] Wherein, Z is impedance, V is the voltage between the first cable and the second cable, and I is current.

[0148] Installation of impedance compensation equipment:

[0149] The impedance compensation device is responsible for compensating the impedance mismatch measured by the impedance detection device and achieving impedance balance by adjusting the inductance, capacitance and resistance values. The main components of this module are adjustable inductor, adjustable capacitor, adjustable resistor and adjustment control circuit.

[0150] Adjustable Inductor:

[0151] The adjustable inductor is connected in the parallel branch of the cable. The main function of the inductor is to compensate the inductive load of the second cable. According to the change of the inductance value, it can reduce or increase the inductive impedance of the connection point.

[0152] The adjustable inductor can be precisely adjusted through electronic control, ensuring the accuracy of the compensation effect.

[0153] Adjustable capacitor:

[0154] The adjustable capacitor is also connected to the parallel branch of the cable, and the function of the capacitor is to compensate the capacitive load of the second cable. It compensates for the capacitance mismatch in the cable system by adjusting the capacitance value.

[0155] When adjusting the capacitor, the overall impedance of the cable system should be monitored in real time to prevent over-compensation or under-compensation.

[0156] Adjustable resistor:

[0157] The adjustable resistor is used to adjust the resistance of the second cable, and compensates for the resistance change of the second cable caused by temperature change or aging by adjusting the resistance value.

[0158] The installation of the adjustable resistor should ensure that it matches the resistance range of the second cable to avoid exceeding the resistance adjustment range allowed by the system design.

[0159] Regulation control circuit:

[0160] Each adjustable element in the impedance compensation device is precisely controlled by the adjustment control circuit, which receives the control signal from the control device and adjusts the parameters of each adjustable element. The adjustment control circuit ensures that the impedance value after each adjustment can quickly reach the set value through an appropriate feedback mechanism.

[0161] Control device connection:

[0162] The control device is the core component of the entire system. It is responsible for processing the data fed back by the impedance detection device, calculating the required compensation amount, and controlling the impedance compensation device to make corresponding adjustments. Its main components include the processor, control circuit, and feedback mechanism.

[0163] Processor installation and connection:

[0164] The processor receives real-time data from the impedance detection device, including voltage, current and impedance value. Based on this data, the processor runs the impedance compensation algorithm to calculate the compensation amount that needs to be adjusted.

[0165] The processor is connected to the regulation control circuit via a communication interface to ensure that the regulation signal can be transmitted in time.

[0166] Control circuit:

[0167] The control circuit generates accurate control signals according to the compensation amount calculated by the processor to adjust the parameters of the adjustable inductor, the adjustable capacitor and the adjustable resistor respectively.

[0168] The connection between the control circuit and the impedance compensation device should be stable and able to respond quickly to the control signal to ensure the response speed of the entire system.

[0169] Feedback Mechanism:

[0170] The system's feedback mechanism monitors the compensated impedance value in real time through sensors and feeds back the compensation effect to the processor. If it detects that the impedance still deviates, the processor will perform a secondary calculation and further adjust the compensation amount until the preset impedance balance target is achieved.

[0171] System operation process:

[0172] Impedance detection and calculation:

[0173] After the system is started, the impedance detection device continuously monitors the voltage and current of the first cable and the second cable to obtain the real-time impedance value. The impedance detection device completes the impedance measurement and calculation through the following steps:

[0174] The voltage sensor collects voltage signals of the first cable and the second cable, and the current sensor collects current signals.

[0175] The analog-to-digital converter converts the analog signal into a digital signal and transmits the digital signal to the impedance calculation unit.

[0176] The impedance calculation unit calculates the current impedance value based on the real-time data and transmits it to the control device.

[0177] Impedance compensation:

[0178] According to the impedance value fed back by the impedance detection device, the control device calculates the required compensation amount through the processor:

[0179] The processor determines whether the current impedance matches the target impedance value. If there is a deviation, the processor determines the inductance, capacitance and resistance values ​​that need to be adjusted according to a predetermined compensation algorithm.

[0180] The control circuit generates a corresponding control signal to adjust the adjustable element of the impedance compensation device to adjust the impedance of the second cable.

[0181] After the impedance compensation device completes the adjustment, the system continues to monitor the impedance of the first cable and the second cable to ensure that the adjusted impedance value reaches a preset range.

[0182] Feedback Adjustment and Adaptive Optimization

[0183] The system has an adaptive feedback mechanism that can continuously monitor the compensation effect and dynamically adjust the compensation amount:

[0184] The feedback mechanism monitors the compensated impedance value through sensors. If the impedance value still deviates from the target value, the processor will further adjust the compensation amount.

[0185] The feedback mechanism combines actual data to optimize the control strategy and ensure that the system can continuously maintain impedance balance under different operating conditions.

[0186] Technical points to note during implementation:

[0187] Selection of high-precision sensors: The accuracy of the voltage and current sensors of the impedance detection equipment directly affects the accuracy of the impedance measurement results, so it is necessary to select suitable high-precision sensors.

[0188] Signal processing stability: When converting analog signals, the analog-to-digital converter needs to ensure the integrity of the signal to avoid data distortion due to noise or interference.

[0189] Dynamic adjustment capability: Each component in the impedance compensation device needs to have good dynamic response capability and be able to quickly adjust according to the control signal to ensure the real-time performance of impedance compensation.

[0190] In order to better demonstrate the specific implementation of this embodiment, the following will describe the working process of the system in detail:

[0191] The system first initializes the electrical parameters of the first cable and the second cable through the impedance detection device. The voltage sensor and the current sensor start working to collect the voltage and current signals of the first cable and the second cable. The ADC converts these analog signals into digital signals and transmits them to the impedance calculation unit for analysis. The impedance calculation unit calculates the impedance value of the first cable and the second cable based on the formula Z = V / I.

[0192] The system enters the real-time monitoring state. The impedance detection device continuously monitors the voltage and current of the first cable and the second cable, and transmits the real-time data to the control device. The control device determines whether the impedance meets the preset matching value based on the detection data. If the impedance deviates from the target value, the system will automatically enter the compensation stage.

[0193] After receiving the adjustment signal from the control device, the impedance compensation device starts the adjustment process of the adjustable inductor, capacitor and resistor. The adjustment control circuit adjusts the parameters of the components according to the control signal to gradually adjust the impedance of the second cable to the target value.

[0194] The system has a feedback mechanism that monitors the compensation effect in real time through sensors. If the compensation effect is not ideal, the system will dynamically adjust the control signal and adjust the compensation element again until the impedance matching reaches the expected standard. This adaptive adjustment function ensures that the system can maintain optimal performance in various operating environments.

[0195] The system records the detailed data of each detection and compensation in the database and uploads it to the remote control center in real time through the communication module. The operator can monitor the impedance changes of the cable through the remote control platform and manually adjust the compensation settings when necessary.

[0196] The dual-split cable connection impedance balancing system of this embodiment has significant advantages in the following aspects:

[0197] High degree of automation: Through real-time detection and automatic compensation, the system can maintain impedance matching without human intervention, greatly improving work efficiency.

[0198] High-precision adjustment: Through precise adjustment of adjustable inductors, capacitors and resistors, the impedance of the first cable and the second cable is ensured to be maintained at an optimal state, reducing signal reflection and energy loss.

[0199] Strong real-time performance: The system's feedback mechanism ensures the rapid response of the compensation process and can adjust impedance fluctuations in a very short time, ensuring the stability of the system.

[0200] Wide adaptability: The present invention is applicable to a variety of scenarios, including high-voltage power transmission systems, communication networks, and other application environments that require precise impedance matching. Whether in extreme environmental conditions or in complex cable networks, the system can maintain stable performance.

[0201] The dual-split cable connection impedance balancing system of this embodiment is suitable for power transmission systems, communication networks and other scenarios that require efficient and stable impedance matching. It can be widely used in urban power grids, long-distance transmission lines, data center communication networks, industrial automation control systems, etc., to help improve system reliability and transmission efficiency.
