Description

Technical Field

[0001] This invention relates to the field of channel switching technology, specifically to a thyristor-triggered redundancy control method for disturbance-free switching. Background Technology

[0002] In control systems for high-power thyristor power conversion, industrial voltage regulation, rectification, and reactive power compensation, the stable and reliable operation of the trigger channel is the core key to ensuring continuous operation of equipment and avoiding load disturbances and device damage.

[0003] Currently, most thyristor-triggered redundancy control schemes in the industry use single voltage or current thresholds or fixed pulse width parameters for fault diagnosis and channel switching. This detection method is relatively crude and has many technical drawbacks. Traditional control methods cannot perform comprehensive and refined verification of the overall shape of the pulse waveform, band similarity, amplitude range, and timing interval. Relying solely on single-point parameter thresholds for fault diagnosis results in extremely poor adaptability. Faced with complex scenarios such as fluctuations in different operating conditions, device aging, and line interference, it is prone to missed or false fault diagnoses, frequently triggering ineffective redundancy switching. This not only fails to promptly identify latent faults such as pulse distortion, amplitude drift, and timing offset, but also interferes with normal equipment operation and reduces system stability.

[0004] Meanwhile, most existing redundancy switching schemes only achieve simple start-stop switching of channels, without establishing a benchmarking and adaptation mechanism for the pulse waveform characteristics of the main and backup channels. The pre-synchronization and output parameters of the backup channel are mostly fixed presets, which cannot be adaptively calibrated and dynamically tuned according to the normal operating waveform characteristics of the main channel. As a result, after the main channel fails and switches over, the amplitude, timing, and waveform consistency of the output pulse of the backup channel deviate from the original waveform of the main channel. This can easily cause problems such as system output voltage jumps, current surges, and waveform distortion, and cannot achieve truly seamless switching.

[0005] Furthermore, traditional solutions have low automation levels and lack standardized closed-loop logic for waveform feature self-learning, fault self-monitoring, and parameter self-calibration. They require manual configuration of trigger parameters based on equipment operating conditions and device characteristics, resulting in high debugging difficulty, high maintenance costs, and difficulty in adapting to the operational needs of different working scenarios. Under long-term operation, they are prone to faults such as thyristor triggering abnormalities, device burnout, and unplanned equipment shutdowns, which seriously restricts the operational reliability and operating condition adaptability of high-power thyristor control systems and cannot meet the stringent operational requirements of uninterrupted continuous production in industrial sites. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a thyristor-triggered redundancy control method with seamless switching, which solves the problem that most existing redundancy switching schemes only achieve simple start-stop switching of channels and do not establish a benchmarking and adaptation mechanism for the pulse waveform characteristics of the primary and backup channels.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a thyristor-triggered redundancy control method with bumpless switching, comprising the following steps: Step 1: Define a set of monitoring cycles. Within each monitoring cycle, monitor the pulse waveform of the main channel in real time. Based on the changing trends and amplitude variations between waveform segments within the monitored pulse waveform, determine the standard waveform segment. Then, lock in the standard characteristics within the standard waveform segment. Specifically, this includes: A set of monitoring cycles is defined, which is a preset cycle. The pulse waveform of the main channel is monitored in real time within the monitoring cycle and recorded as the waveform to be verified. Within the waveform to be verified, the peak point is marked. The waveform segment before the peak point is in an upward trend, and the waveform segment after the peak point is in a downward trend. The waveform segment between adjacent peak points is recorded as the built-in band. The similarity of adjacent built-in bands is checked: the overlap between three consecutive sets of built-in bands is identified, prioritizing the overlap between the first and second sets of built-in bands. The first set of built-in bands is then shifted forward so that the first peak points of the first and second sets of built-in bands are shifted to the same point in time. After the shift is completed, the overlapping bands of the first and second sets of built-in bands are recorded, and the proportion of the overlapping band length to the length of the first set of built-in bands is determined. Next, determine the proportion of the overlapping band line length located in the second group of built-in bands. Take the average of the two determined proportions of line length and record the average proportion as the first average. Then, determine the average proportion associated with the second group of built-in bands and the third group of built-in bands and record it as the second average. Confirm the average of the first average and the second average. Record the determined average as the overlap of the three groups of continuous built-in bands. Confirm the overlap of the three groups of continuous built-in bands from front to back. Three consecutive sets of built-in bands with an overlap of ≥90% are designated as standard waveform segments. If there are multiple sets of standard waveform segments, the set with the largest overlap value is selected as the standard waveform segment. Determine the maximum and minimum amplitude values ​​within the standard waveform segment, lock a set of amplitude intervals, then determine the interval duration between adjacent peak points within the standard waveform segment, and generate a duration interval based on the two determined interval durations. Record the locked amplitude interval and duration interval as the standard characteristics of the corresponding standard waveform segment. Step 2: Re-monitor the pulse waveforms subsequently generated by the main channel, and lock the amplitude and interval duration in real time to confirm whether the monitoring characteristics monitored by the main channel deviate from the standard characteristics. If they deviate, start the backup channel; if they do not deviate, continue to monitor the pulse waveforms and determine the monitoring characteristics. The specific method is as follows: The generated peak points are determined in real time from the pulse waveform monitored subsequently, and the built-in bands between adjacent peak points are determined. Identify the maximum and minimum amplitude values ​​within the built-in band, generate amplitude intervals, and record them as the first feature of the corresponding built-in band. Then identify the interval duration between the two sets of peak points of the built-in band and record it as the second feature of the corresponding built-in band. The amplitude range of the first feature is compared with that of the standard feature: the amplitude range that does not overlap with the first feature and the amplitude range is identified and recorded as the deviation range. The range length C1 of the deviation range is identified, and then the range length C2 of the amplitude range is determined. If C1 and C2 satisfy: C1÷C2≥10%, the backup channel is started; otherwise, the confirmation process of the second feature is carried out. Identify whether the second feature belongs to the duration interval in the standard features. If it does, continue the subsequent monitoring process. If it does not, start the backup channel. Step 3: Use the pulse voltage and pulse current of the main channel as the trigger voltage and trigger current of the backup channel, and monitor the pulse waveform generated by the backup channel. Identify the waveform characteristics from the monitored pulse waveform and determine the deviation of the waveform characteristics from the standard characteristics. Based on the deviation, determine the debugging direction. The specific method is as follows: A new set of monitoring cycles is defined, which is a preset cycle. Within the monitoring cycle, the pulse waveform of the backup channel is monitored in real time and recorded as the waveform to be verified. The same determination method as that used for the main channel standard waveform segment is adopted to lock the standard waveform segment within the pulse waveform of the backup channel; Within the standard waveform segment, the amplitude range and duration range are locked and recorded as the waveform characteristics associated with the corresponding pulse waveform; The specific method for determining the deviation of waveform characteristics from standard characteristics is as follows: The amplitude range associated with the waveform feature is denoted as the waveform range, and the amplitude range associated with the standard feature is denoted as the standard range. If the waveform range belongs to the standard range, no processing is required. If the waveform range does not belong to the standard range, the deviation status confirmation process is executed: determine the excess range of the waveform range that exceeds the standard range, record the numerical range length F1 of the excess range, and process F1 as a positive value. Then determine the lower range of the waveform range that is lower than the standard range, record the numerical range length F2 of the lower range, and process F2 as a negative value. Summate F1 and F2 to determine the total processing value. If the total processing value is positive, the adjustment direction is marked as the direction of trigger voltage downward adjustment. If the total processing value is negative, the adjustment direction is marked as the direction of trigger voltage upward adjustment. If the total processing value = 0, no processing is required. The duration interval associated with the waveform feature is recorded as the waveform duration, and the duration interval associated with the standard feature is recorded as the standard duration. If the waveform duration belongs to the standard duration, no processing is required. If the waveform duration does not belong to the standard duration, the deviation state determination process is executed: determine the excess range of the waveform duration that exceeds the standard duration, record the length of the excess range B1, and process B1 as a positive value. Then determine the lower range of the waveform duration that is lower than the standard duration, record the length of the lower range B2, and process B2 as a negative value. Sum B1 and B2 to determine the total processing value. If the total processing value is positive, the adjustment direction is marked as the trigger current downward adjustment direction. If the total processing value is negative, the adjustment direction is marked as the trigger current upward adjustment direction. If the total processing value = 0, no processing is required. Step 4: Based on the locked debugging direction, adjust the trigger voltage and trigger current of the backup channel in real time until the waveform characteristics of the backup channel pulse waveform meet the standard, including: Based on the determined direction of the trigger parameter adjustment, the trigger parameters of the backup channel are adjusted in real time. The trigger parameters include the trigger voltage and the trigger current. During the real-time debugging process, the three sets of waveform segments generated sequentially are confirmed in real time, and the waveform characteristics associated with the three sets of continuous waveform segments are confirmed by using the same processing method as standard waveform segments. The real-time debugging process stops when all determined waveform characteristics belong to the standard characteristics, and the debugging process of the backup channel trigger parameters is completed.

[0008] This invention provides a non-disruptive switching method for redundancy control of thyristor-triggered systems. Compared with existing technologies, it has the following advantages: By establishing a standardized feature judgment system based on pulse waveform band overlap, amplitude range, and duration range, closed-loop control with accurate identification of main channel faults, seamless switching of backup channels, and adaptive parameter tuning is achieved, demonstrating significant technical advantages and engineering application value.

[0009] First, this method abandons the traditional crude fault identification mode of single parameter threshold judgment. It relies on the similarity verification mechanism of multiple continuous pulse built-in bands to autonomously calibrate standard waveform segments and standard features. It can adapt to pulse waveform benchmarks under different working conditions and device characteristics, effectively avoiding the problems of poor adaptability, misjudgment and omission of fixed judgment standards, and greatly improving the accuracy and anti-interference ability of main channel pulse abnormality fault identification.

[0010] Secondly, this method achieves graded fault determination by quantifying the amplitude deviation ratio and pulse interval duration deviation, and only activates the backup channel when the pulse waveform characteristics substantially exceed the standard, avoiding ineffective redundant switching actions and ensuring the stability and continuity of the main channel's normal operation.

[0011] Meanwhile, after switching, this solution performs directional adaptive debugging of the backup channel trigger voltage and trigger current based on the standard characteristics of the main channel. By iteratively tuning the backup channel operating parameters through closed-loop comparison of waveform characteristics, the amplitude characteristics, timing characteristics, and waveform consistency of the backup channel output pulse are completely matched with the standard waveform of the main channel. This completely solves the problems of voltage jumps, current surges, and waveform distortion caused by the phase, amplitude, and pulse width deviations of the backup channel pulse in traditional redundancy switching, and truly achieves a disturbance-free entire process of trigger channel switching.

[0012] Furthermore, this method relies on unified waveform feature extraction and verification logic to complete the entire process control of standard calibration, fault monitoring, and parameter tuning. It eliminates the need for manual configuration of trigger parameters and enables equipment to learn automatically upon power-on, switch automatically during faults, and adapt parameters automatically. This reduces equipment debugging and maintenance costs, effectively improves the automation level and operating condition adaptability of the thyristor trigger redundancy control system, and ensures the long-term continuous, stable, and safe operation of high-power thyristor equipment from the triggering source. It also greatly reduces operational risks such as equipment downtime, device burnout, and load disturbances. Attached Figure Description

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Example 1 Please see Figure 1 This application provides a method for non-disruptive switching of thyristor-triggered redundancy control, comprising the following steps: Step 1: Define a set of monitoring cycles, monitor the pulse waveform of the main channel in real time within the monitoring cycle, determine the standard waveform segment based on the changing trend and amplitude change between the waveform segments within the monitored pulse waveform, and lock the standard feature within the standard waveform segment. Step 2: Re-monitor the pulse waveforms generated by the main channel, and lock the amplitude and interval in real time to confirm whether the monitoring characteristics monitored by the main channel deviate from the standard characteristics. If they deviate, start the backup channel. If they do not deviate, continue to monitor the pulse waveforms and determine the monitoring characteristics. Step 3: Use the pulse voltage and pulse current of the main channel as the trigger voltage and trigger current of the backup channel, monitor the pulse waveform generated by the backup channel, lock the waveform characteristics from the monitored pulse waveform, determine the deviation of the waveform characteristics from the standard characteristics, and lock the debugging direction based on the deviation. Step 4: According to the locked debugging direction, adjust the trigger voltage and trigger current of the backup channel in real time until the waveform characteristics of the backup channel pulse waveform meet the standard.

[0016] Example 2 In a specific implementation process, this embodiment is a further implementation of the above embodiment, and specifically includes: In step one, the process of determining the standard waveform segment specifically includes: A set of monitoring cycles is defined, which are preset cycles determined in advance by the operator based on experience. Generally, the value is 5 minutes. Within the monitoring cycle, the pulse waveform of the main channel is monitored in real time and recorded as the waveform to be verified. Within the waveform to be verified, the peak point is marked. The waveform segment before the peak point is in an upward trend, and the waveform segment after the peak point is in a downward trend. The waveform segment between adjacent peak points is recorded as the built-in band. The similarity of adjacent built-in bands is checked: the overlap between three consecutive sets of built-in bands is identified. First, the overlap between the first and second sets of built-in bands is determined. The first set of built-in bands is then shifted so that the first peak points of the first and second sets of built-in bands are at the same point in time. After the shift, the overlapping bands between the first and second sets are recorded, and the percentage of the overlapping band's length relative to the first set of built-in bands is determined. Then, the percentage of the overlapping band's length relative to the second set of built-in bands is determined. The two percentages are averaged to determine the first average. The percentage of the average associated with the second and third sets of built-in bands is then determined and recorded as the second average. The first and second averages are then compared... The mean is confirmed, and the determined mean is recorded as the overlap of three sets of continuous built-in bands. The overlap of the three sets of continuous built-in bands is confirmed sequentially from front to back. Specifically, within the corresponding pulse waveform, there are sequentially associated waveform segments. From front to back, there are sequentially adjacent corresponding waveform segments. There is a corresponding overlap between the corresponding waveform segments. First, the proportion of the band associated between the first and second built-in bands is determined, then the proportion of the band between the second and third built-in bands is determined, and then the average of the determined proportions is confirmed sequentially to lock the corresponding average proportion. Then, the average proportion of the subsequent associated bands is confirmed sequentially from front to back. Subsequently, based on the average proportion between multiple continuous waveform segments, the corresponding standard waveform segment that meets the band pattern is locked. Three consecutive sets of built-in bands with an overlap of ≥90% are designated as standard waveform segments. If there are multiple sets of standard waveform segments, the set with the largest overlap value is selected as the standard waveform segment. Determine the maximum and minimum amplitude values ​​within the standard waveform segment, lock a set of amplitude intervals, then determine the interval duration between adjacent peak points within the standard waveform segment, and generate a duration interval based on the two determined interval durations. Record the locked amplitude interval and duration interval as the standard characteristics of the corresponding standard waveform segment.

[0017] Step two, the specific method for confirming whether the monitored characteristics deviate from the standard characteristics is as follows: The generated peak points are determined in real time from the pulse waveform monitored subsequently, and the built-in bands between adjacent peak points are determined. Identify the maximum and minimum amplitude values ​​within the built-in band, generate amplitude intervals, and record them as the first feature of the corresponding built-in band. Then identify the interval duration between the two sets of peak points of the built-in band and record it as the second feature of the corresponding built-in band. The amplitude range of the first feature is compared with that of the standard feature: Non-overlapping amplitude ranges between the first feature and the amplitude range are identified and recorded as deviation ranges. The range length C1 of the deviation range is determined (if only one set of deviation ranges exists, the numerical length of that set is determined; if two sets of deviation ranges exist, the numerical lengths of the two sets are summed to lock the range length of the corresponding deviation range). The range length C2 of the amplitude range (i.e., the numerical length of the corresponding range) is then determined. If C1 and C2 satisfy: C1 ÷ C2 ≥ 10%, the backup channel is activated; otherwise, the confirmation process for the second feature is initiated. Identify whether the second feature belongs to the time interval in the standard features. If it does, continue the subsequent monitoring process. If it does not, activate the backup channel.

[0018] Step 3, the specific method for determining the corresponding waveform characteristics within the pulse waveform is as follows: A new set of monitoring cycles is defined. These monitoring cycles are preset and determined in advance by the operators based on their experience. They are generally set to 5 minutes. Within the monitoring cycle, the pulse waveform of the backup channel is monitored in real time and recorded as the waveform to be verified. The same determination method as that used for the main channel standard waveform segment is adopted to lock the standard waveform segment within the pulse waveform of the backup channel; Within the standard waveform segment, the amplitude range and duration range are locked and recorded as the waveform characteristics associated with the corresponding pulse waveform; The specific method for determining the deviation of waveform characteristics from standard characteristics is as follows: The amplitude range associated with the waveform feature is denoted as the waveform range, and the amplitude range associated with the standard feature is denoted as the standard range. If the waveform range belongs to the standard range, no processing is required. If the waveform range does not belong to the standard range, the deviation status confirmation process is executed: determine the excess range of the waveform range that exceeds the standard range, record the numerical range length F1 of the excess range, and process F1 as a positive value. Then determine the lower range of the waveform range that is lower than the standard range, record the numerical range length F2 of the lower range, and process F2 as a negative value. Summate F1 and F2 to determine the total processing value. If the total processing value is positive, the adjustment direction is marked as the direction of trigger voltage downward adjustment. If the total processing value is negative, the adjustment direction is marked as the direction of trigger voltage upward adjustment. If the total processing value = 0, no processing is required. The duration interval associated with the waveform feature is recorded as the waveform duration, and the duration interval associated with the standard feature is recorded as the standard duration. If the waveform duration belongs to the standard duration, no processing is required. If the waveform duration does not belong to the standard duration, the deviation state determination process is executed: determine the excess range of the waveform duration that exceeds the standard duration, record the length of the excess range B1, and process B1 as a positive value. Then determine the lower range of the waveform duration that is lower than the standard duration, record the length of the lower range B2, and process B2 as a negative value. Sum B1 and B2 to determine the total processing value. If the total processing value is positive, the adjustment direction is marked as the trigger current downward adjustment direction. If the total processing value is negative, the adjustment direction is marked as the trigger current upward adjustment direction. If the total processing value = 0, no processing is required.

[0019] Step four, the real-time debugging process includes: Based on the determined direction of the trigger parameter adjustment, the trigger parameters of the backup channel are adjusted in real time. The trigger parameters include the trigger voltage and the trigger current. During the real-time debugging process, the three sets of waveform segments generated sequentially are confirmed in real time, and the waveform characteristics associated with the three sets of continuous waveform segments are confirmed by using the same processing method as standard waveform segments. The real-time debugging process stops when all determined waveform characteristics belong to the standard characteristics, and the debugging process of the backup channel trigger parameters is completed.
