[0002] With the development of power technology, users are becoming increasingly sensitive to power system faults. Power system faults can be divided into hard faults and soft faults. Hard faults refer to permanent damage to the circuit, usually manifested as open circuits, short circuits, or physical damage to components. Soft faults, on the other hand, usually do not lead to complete circuit failure, but if they persist for a long time, they may cause a gradual deterioration in circuit performance, such as aging wires and broken insulation. In this case, even without a hard fault, the circuit reliability will gradually decrease. Therefore, regular inspection and maintenance of the circuit system to prevent circuit faults and improve the stability of the power system is crucial.

[0003] Traditionally, traveling wave (TW) methods are used to locate and detect power system faults. This involves connecting a TW device and a receiver at both ends of a cable, measuring the distance between the transmitter and receiver, and comparing the distances to determine the fault location.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0037] In one embodiment, such as Figure 1 As shown, a power fault detection system 100 is provided. The system includes: a receiver 101, a digital processing module 102, a transceiver controller 103, and a host computer 104; the receiver 101 is communicatively connected to the digital processing module 102; the transceiver controller 103 is communicatively connected to both the digital processing module 102 and the host computer 104.

[0038] Receiver 101 is used to acquire the power line carrier signal to be processed, sample the power line carrier signal to obtain the sampled data of the power line carrier signal, and send the sampled data to the digital processing module 102;

[0039] The digital processing module 102 is used to perform digital filtering, synchronization detection and Fourier transform on the sampled data to obtain the channel characteristic information and communication content information of the power line carrier signal, and send the channel characteristic information and communication content information to the transceiver controller 103.

[0040] The transceiver controller 103 is used to send channel characteristic information and communication content information to the host computer 104;

[0041] The host computer 104 is used to locate and detect faults based on channel characteristic information and communication content information.

[0042] Specifically, refer to Figure 1 In response to a fault detection command for the power line carrier system, the power line fault detection system 100 acquires the power line carrier signal from the power line carrier system via receiver 101. It then performs signal decoupling, analog front-end processing, and analog-to-digital conversion on the power line carrier signal to obtain sampled data. This sampled data is sent to the digital processing module 102. The digital processing module 102 performs digital filtering, synchronization detection, and fast Fourier transform on the sampled data to obtain channel characteristic information and communication content information of the power line carrier signal. This information is then transmitted to the transceiver controller 103. The transceiver controller 103 transmits the channel characteristic information and communication content information to the host computer 104. Finally, the host computer 104 performs fault location and fault detection on the power line carrier system based on the channel characteristic information and communication content information.

[0043] Signal decoupling refers to filtering out interference signals such as 220V / 50Hz AC power on the power line to obtain the carrier signal carrying the communication content information; analog front-end processing refers to amplifying, filtering and conditioning the received analog signal to make it suitable for subsequent analog-to-digital conversion and digital signal processing; analog-to-digital conversion operation refers to converting the analog signal into a digital signal.

[0044] Digital filtering refers to filtering digital signals to remove noise and interference; synchronization detection is used to determine the carrier frequency, phase, and other parameters of the received signal in order to correctly demodulate the data information; and fast Fourier transform processing is used to perform spectral analysis on the sampled data to extract channel feature information and data information.

[0045] Among them, channel characteristic information includes parameters such as pilot signals and channel response, which are used to estimate and compensate the channel to improve communication quality; communication content information refers to the actual transmitted communication content, which needs to be demodulated, decoded and other operations to recover the original communication content.

[0046] For example, by measuring the signal strength of a pilot signal and comparing it to the signal strength under normal conditions, a significant decrease in signal strength may indicate signal attenuation or loss, which could be caused by a break, poor contact, or high impedance fault in the power line. By analyzing the signal quality of the pilot signal, such as the signal-to-noise ratio (SNR) or bit error rate (BER), a decline in signal quality may indicate interference, increased noise, or signal distortion, which may be related to faults in the power line. By sending a series of pilot signals at different frequencies and measuring the response at each frequency, and by analyzing the frequency response characteristics, filtering effects or frequency-dependent faults in the power line can be identified; for example, some faults may only affect signals within a specific frequency range.

[0047] In the aforementioned power fault detection system, the receiver 101 first acquires the power carrier signal to be processed, samples the power carrier signal to obtain sampled data, and then the digital processing module 102 performs digital filtering, synchronization detection, and fast Fourier transform on the sampled data to obtain the channel characteristic information and communication content information of the power carrier signal. The transceiver controller 103 then forwards the received channel characteristic information and communication content information to the host computer 104. Finally, the host computer 104 performs fault location and fault detection on the power system based on the channel characteristic information and communication content information. By extracting and analyzing the channel characteristic information and communication content information of the power carrier signal, fault location and detection can be performed quickly, improving fault detection efficiency. Furthermore, it eliminates the need for additional sensor equipment, reducing costs and meeting the needs of real-time monitoring of power line networks.

[0048] In one embodiment, the digitization processing module 102 is further configured to generate an interrupt request signal based on channel feature information and communication content information, and send the interrupt request signal to the transceiver controller 103; the transceiver controller 103 is further configured to parse the interrupt request signal to obtain channel feature information and communication content information, perform information verification on the channel feature information and communication content information, and send the channel feature information and communication content information to the host computer 104 if the information verification passes.

[0049] Specifically, the digitization processing module 102 generates an interrupt request signal based on channel characteristic information and communication content information, and sends the interrupt request signal to the transceiver controller 103. The transceiver controller 103 obtains the channel characteristic information and data information from the digitization module based on the interrupt request signal, performs information verification on the channel characteristic information and communication content information, and sends the channel characteristic information and communication content information to the host computer 104 if the information verification passes. In this embodiment, after obtaining the channel characteristic information and data information, the digitization processing module 102 sends an interrupt request signal to the transceiver controller 103. The interrupt request signal requests the transceiver controller 103 to copy the channel characteristic information to its storage location. The transceiver controller 103 utilizes the processing capabilities of the chip module, the memory interface, and the data transmission protocol to complete the data copying process.

[0050] It should be noted that, during data replication, the transceiver controller 103 employs a verification mechanism to detect and correct errors during the replication process to ensure consistency before and after data replication. To guarantee the consistency between the stored and output results, the verification results are used as a condition for outputting channel characteristic information such as pilot signals. When the verification results are consistent, it indicates that the current data meets the consistency requirement and can be output as channel characteristic information for the power line carrier system.

[0051] For example, before data copying, the digitization module 102 generates a checksum for the data and transmits the data along with the checksum to the transceiver controller 103. After receiving the data, the transceiver controller 103 recalculates the checksum and compares it with the data. If the checksums match, the transceiver controller 103 can output the data to the host computer 104. If the checksums do not match, the transceiver controller 103 does not output the data to the host computer.

[0052] In one embodiment, the channel feature information includes a first check bit, and the communication content information includes a second check bit; the transceiver controller 103 is further configured to recalculate the check bits based on the channel feature information and the communication content information to obtain a third check bit and a fourth check bit respectively; if the first check bit is the same as the third check bit and the second check bit is the same as the fourth check bit, it is determined that the information verification has passed; otherwise, it is determined that the information verification has failed.

[0053] Specifically, the transceiver controller 103 can use a data verification mechanism to generate a check bit. This data verification mechanism includes, but is not limited to, parity checking and cyclic redundancy check. When the first check bit and the third check bit are the same, and the second check bit and the fourth check bit are the same, the transceiver controller 103 determines that the data verification is successful; when the first check bit and the third check bit are different, and / or the second check bit and the fourth check bit are different, the transceiver controller 103 determines that the data verification has failed.

[0054] Successful data verification indicates that no errors occurred during the data copying process, while failure to verify data indicates that errors occurred during the data copying process.

[0055] In this embodiment, the transceiver controller 103 compares the first check bit with the third check bit, and the second check bit with the fourth check bit to determine whether an error has occurred during the data copying process, thereby improving the accuracy of fault detection.

[0056] In one embodiment, such as Figure 2 As shown, the digitization processing module 102 includes a first register and a second register, and the transceiver controller 103 includes a third register and a fourth register. The digitization processing module 102 is also used to save channel feature information to the first register, demodulate and decode the communication content information to obtain the original communication content, and save the original communication content to the second register. The digitization processing module 102 is also used to send the channel feature information in the first register to the third register of the transceiver controller 103, and send the original communication content in the second register to the fourth register of the transceiver controller 103.

[0057] Specifically, refer to Figure 2 The digitization processing module 102 saves the channel feature information to its first register, demodulates and decodes the communication content information to obtain the demodulated and decoded original communication content, and saves the original communication content to its second register. The digitization processing module 102 transmits the channel feature information in the first register to the third register of the transceiver controller 103, and transmits the demodulated and decoded original communication content in the second register to the fourth register of the transceiver controller 103.

[0058] In this embodiment, by caching channel feature information in the first and third registers, and caching the original communication content after demodulation and decoding in the second and fourth registers, data corruption can be avoided.

[0059] In one embodiment, the receiver 101 is further configured to decouple the power line carrier signal to obtain a decoupled analog carrier signal, perform analog front-end processing on the analog carrier signal to obtain a target analog signal, and perform analog-to-digital conversion on the target analog signal to obtain a target digital signal, which serves as the sampling data of the power line carrier signal.

[0060] Specifically, receiver 101 includes a capacitive-inductive coupler, an analog front-end, and an analog-to-digital converter (ADC). The analog front-end includes an amplifier, a bandpass filter, a low-pass filter, and a limiting circuit. The capacitive-inductive coupler decouples the power line carrier signal. The decoupled signal is then processed sequentially through the amplifier, bandpass filter, low-pass filter, and limiting circuit to obtain an analog signal. This analog signal is then passed through the ADC to obtain sampled data. Digital processing module 102 includes a digital filter, a phase-locked loop (PLL), and a fast Fourier transform (FFT). The sampled data is filtered by the digital filter, the PLL tracks and locks the carrier frequency and phase of the received signal, and the FFT separates channel characteristic information, such as pilot signals used for channel estimation, from the data information. The transceiver controller 103 is a chip module used to control the reception and transmission of signals. The transceiver controller 103 transmits channel characteristic information and communication content information to the host computer 104. The host computer 104 performs signal strength analysis, signal quality analysis and frequency response analysis on the signal characteristic information and communication content information to locate and detect faults in the power line carrier system.

[0061] In one embodiment, such as Figure 3 As shown, a power fault detection method is provided, which can be applied to... Figure 1 Taking the power fault detection system 100 in the example, the following steps are included:

[0062] Step S301: Obtain the power line carrier signal to be processed, sample the power line carrier signal, and obtain the sampled data of the power line carrier signal.

[0063] Step S302 involves performing digital filtering, synchronization detection, and Fourier transform on the sampled data to obtain channel characteristic information and communication content information of the power line carrier signal.

[0064] Step S303: Based on channel characteristic information and communication content information, perform fault location and fault detection.

[0065] Specifically, the power fault detection system first acquires the power carrier signal to be processed, samples the power carrier signal to obtain sampled data of the power carrier signal; then performs digital filtering, synchronization detection and Fourier transform on the sampled data to obtain the channel characteristic information and communication content information of the power carrier signal; finally, based on the channel characteristic information and communication content information, it performs fault location and fault detection.

By extracting and analyzing the channel characteristic information and communication content information of the power carrier signal, fault location and fault detection can be performed quickly, improving the efficiency of fault detection. Furthermore, it eliminates the need for additional sensor equipment, reducing costs, and can meet the needs of real-time monitoring of power line networks.
