Description

Technical Field

[0001] This invention relates to the field of power management technology, and more specifically to an ultra-high precision clock synchronization system for power systems based on rubidium atomic clocks. Background Technology

[0002] Traditional power systems often use ordinary temperature-controlled crystal oscillators paired with a single satellite for time synchronization. These crystal oscillators suffer from significant long-term frequency drift, resulting in timekeeping accuracy only at the millisecond level, which is insufficient for synchronizing phasor measurement devices. Rubidium atomic clocks, on the other hand, possess superior performance with short-term stability ≤1e-12 / 1s and long-term stability ≤1e-13 / day, exhibiting far lower frequency drift than ordinary temperature-controlled crystal oscillators, thus improving time synchronization stability. However, during rubidium atomic clock time synchronization, it is necessary to collect the equipment's operating status to address any anomalies. Traditional synchronization systems employ a conventional data acquisition-packaging-transmission-analysis model, resulting in data transmission delays of hundreds of milliseconds or even seconds. When anomalies such as satellite lockout or link jitter occur, maintenance personnel cannot obtain real-time data, leading to delays in fault location and handling, and extending the duration of system anomalies. Summary of the Invention

The synchronization device is set to master clock mode, with the priority being rubidium atomic clock > satellite time source > ground time source. After a preset period, the rubidium atomic clock is calibrated through the satellite time source. The synchronization module, connected to the setting module, is used to establish a connection channel between the synchronization platform and multiple power system clock data acquisition points. The connection channel includes a transmission trigger surface, a receiving trigger surface, and a conversion surface of the transmission trigger surface. Based on the real-time acquisition of multi-dimensional indicators of power system clock synchronization by the synchronization platform, the connection channel transmits the multi-dimensional indicators to the synchronization platform.

The number of channels in the transmission trigger surface and the receiving trigger surface is the same as the number of types of type points, and there is a one-to-one correspondence between the channels and the type points.

[0008] In a preferred embodiment, the transmitting unit includes: The data acquisition unit is used to collect multi-dimensional indicators of the corresponding rubidium atomic clock and synchronization device according to the acquisition point, classify the multi-dimensional indicators into parameters, and obtain various types of indicator parameters. The conversion unit is used to provide multiple types of indicator parameters to the corresponding conversion area in the conversion surface based on the indicator type label. The conversion area stores multiple trigger packets, which are used to wrap and mark the parameter values ​​of the indicator parameters. The trigger unit is used to release trigger packets sequentially to the access points of the transmission trigger surface corresponding to the parameter values ​​in the conversion area according to the collection time sequence of multi-dimensional indicators. Based on the indicator type label corresponding to the trigger packet, it matches the type point corresponding to the access point. The trigger packet triggers the channel of the corresponding type point to open according to the corresponding trigger strength to complete the signal transmission.

This allows for near-synchronous data acquisition and analysis, improving the timeliness of data transmission. Consequently, it enables more timely feedback on clock synchronization anomalies in the power system, reducing the impact of clock synchronization anomalies on the power system.

Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0016] Example 1, please refer to Figure 1 As shown in this embodiment, the ultra-high precision clock synchronization system for power systems based on rubidium atomic clocks includes: The module is used to connect the rubidium atomic clock to the synchronization device of the power system, and connect the synchronization device to the satellite time source and the ground time source. The synchronization device is set to master clock mode, with the priority being rubidium atomic clock > satellite time source > ground time source. After a preset period, the rubidium atomic clock is calibrated through the satellite time source. The synchronization module, connected to the setting module, is used to establish a connection channel between the synchronization platform and multiple power system clock data acquisition points. The connection channel includes a transmission trigger surface, a receiving trigger surface, and a conversion surface of the transmission trigger surface. Based on the real-time acquisition of multi-dimensional indicators of power system clock synchronization by the synchronization platform, the connection channel transmits the multi-dimensional indicators to the synchronization platform. The execution module, connected to the synchronization module, is used to switch execution levels according to the abnormality when multiple dimensions of indicators are abnormal in the synchronization platform.

[0017] It should be noted that information transmission can be initiated simply by triggering the channel through the docking channel. The transmission work is prepared at both ends of the channel, and only channel triggering is required, which saves the data transmission process and makes the data acquisition and analysis closer to the synchronous effect, improving the timeliness of data transmission. This allows for more timely feedback on abnormal clock synchronization problems in the power system, reducing the impact of clock synchronization abnormalities on the power system.

[0018] In one embodiment, the setting module includes: The parameter configuration unit is used to configure the parameters of the rubidium atomic clock and the synchronization device of the power system, including setting the master clock mode of the synchronization device and setting the discipline function of the rubidium atomic clock. The calibration setting unit is used to calibrate the rubidium atomic clock via a satellite time source after a preset time period, wherein the preset time period is 24 hours of preheating of the rubidium atomic clock.

[0019] It should be noted that the rubidium atomic clock and synchronization device are deployed nearby and reliably grounded; access to the BeiDou / GPS dual-mode satellite time source requires an unobstructed antenna and an IRIG-B (DC) ground time source, with fiber optic transmission being the preferred choice; a TMU monitoring board is configured, and NTP / SNTP and GOOSE signal monitoring functions are enabled; the synchronization device is set to master clock mode, with the priority as follows: rubidium atomic clock > BeiDou / GPS > IRIG-B (DC); the network port IP is configured (different boards have IPs belonging to different network segments), and the serial port parameters are set to the default baud rate of 960. 0, no verification; enable rubidium atomic clock frequency standard training function, set training period of 1 hour, target training level ≥5 / 5; after 24 hours of warm-up, calibrate the rubidium atomic clock via satellite / ground time source, with a deviation from UTC ≤100ns; adopt a hardware forwarding scheme, the master clock calculates the transmission delay, and automatically sets a compensation value at the ns level to offset link errors; calibrate the internal delay between the rubidium atomic clock and the synchronization device, set a fixed compensation value, the master clock calculates the one-way transmission delay (including fiber optic link and interface conversion delay), and automatically sets a delay compensation value to offset link errors, with a compensation accuracy ≤20ns. The internal delay between the rubidium atomic clock and the synchronization device is calibrated, and a fixed compensation value is set to ensure internal timing consistency, thus guaranteeing the accuracy of the rubidium atomic clock.

[0020] In one embodiment, the synchronization module includes: The unit is used to configure the acquisition points for the corresponding rubidium atomic clock and synchronization device, and to establish the docking channel between the acquisition points and the synchronization platform; The transmitting unit is used to collect multi-dimensional indicators of the corresponding rubidium atomic clock and synchronization device based on the collection point, wrap the multi-dimensional indicators with the conversion surface to form a temporary contact, and transmit the signal through the transmission trigger surface. The receiving unit is used to receive trigger signals through the synchronization platform, convert them into multi-dimensional indicators, and store them in the synchronization platform.

[0021] In one embodiment, the assembly unit includes: The first setting unit is used to set the transmission trigger surface for the corresponding acquisition point. The transmission trigger surface consists of multiple access points, each of which is set with a different type point. Different parameter values ​​are configured for the type points of the multiple access points. The second setting unit is used to configure the conversion surface corresponding to the transmission trigger surface. The conversion surface is composed of conversion areas corresponding to multiple type points. Each conversion area has a corresponding index type label. Different trigger strengths are configured for each conversion area. The trigger strength is the communication strength. The third setting unit is used to set the receiving trigger surface for the corresponding synchronization platform. The receiving trigger surface consists of multiple access points, each of which is set with different types of points. Each access point is connected to a receiving point. Each access point of the receiving trigger surface has parameter values ​​configured for multiple types of points in the corresponding transmission trigger surface. The connection unit is used to connect the access point of the transmission trigger surface with the access point of the receiving trigger surface with the same parameter value through multiple channels. The number of channels in the transmission trigger surface and the receiving trigger surface is the same as the number of types of type points, and there is a one-to-one correspondence between the channels and the type points.

[0022] In one embodiment, the transmitting unit includes: The data acquisition unit is used to collect multi-dimensional indicators of the corresponding rubidium atomic clock and synchronization device according to the acquisition point, classify the multi-dimensional indicators into parameters, and obtain various types of indicator parameters. The conversion unit is used to provide multiple types of indicator parameters to the corresponding conversion area in the conversion surface based on the indicator type label. The conversion area stores multiple trigger packets, which are used to wrap and mark the parameter values ​​of the indicator parameters. The trigger unit is used to release trigger packets sequentially to the access points of the transmission trigger surface corresponding to the parameter values ​​in the conversion area according to the collection time sequence of multi-dimensional indicators. Based on the indicator type label corresponding to the trigger packet, it matches the type point corresponding to the access point. The trigger packet triggers the channel of the corresponding type point to open according to the corresponding trigger strength to complete the signal transmission. After the transmission trigger, the trigger packet is immediately disconnected from the access point. The parameter values ​​in the trigger packet are marked and eliminated and re-stored in the conversion area to be used again.

[0023] In one embodiment, the receiving unit includes: The sensing unit is used to determine the corresponding parameter type based on the type point of the channel and the corresponding trigger strength when the access point in the synchronization platform is activated. The integration unit is used to integrate the parameter values ​​and parameter types configured by the parameter points to obtain the indicator parameters. It combines the indicator parameters obtained by triggering at the same time to obtain multi-dimensional indicators collected at the same time. The data acquisition and storage unit is used to continuously acquire data from the access point of the trigger plane regarding channel activation and the trigger strength of activation, obtain continuous multi-dimensional indicators, and store them.

[0024] It should be noted that a data acquisition point is configured for the rubidium atomic clock and synchronization device. This data acquisition point is used to collect: clock discipline status monitoring, specifically the discipline status of the frequency source, whether it has been disciplined, and whether the discipline level is ≥5 / 5; if it shows "discipline in progress," continue to observe for 24 hours (rubidium clock stabilization warm-up period); satellite time source status monitoring: collect device status - BeiDou / GPS status, confirm that the number of locked satellites is ≥4 and whether the synchronization status is synchronized; monitor satellite antenna status: collect device status - BeiDou / GPS status - antenna status, collect whether there are any short circuits / open circuits, if there are any abnormalities, check the antenna layout; output signal accuracy monitoring: collect PPS signal time difference data: ensure the deviation is ≤30ns, if it exceeds the threshold, check whether there is any interference in the TTL interface (rising edge ≤100ns) or fiber optic transmission link; transmission delay jitter monitoring: collect the transmission delay data of the main link (satellite time source - device - terminal equipment) in real time, collect the delay fluctuation value, and continuously track whether it exceeds 200ns. The data to be collected is substantial and diverse, and needs to be synchronized to a synchronization platform for analysis. The synchronization platform also controls and executes responses to anomalies. Therefore, the timeliness of data transmission is crucial. A connection channel is established here. This channel does not require data transmission; only channel triggering is needed to acquire data. Channel triggering is significantly faster than data transmission, ensuring timely data arrival at the synchronization platform. This enables real-time data acquisition and analysis, improving the guarantee of power system timing consistency. Specifically, a transmission trigger surface is set up at the acquisition points. This transmission trigger surface consists of multiple access points, which are storage points used for subsequent load trigger packets. The trigger packets are virtual machines that can establish connections with the corresponding channels at the access point locations. Each access point is configured with different type points. A single transmission trigger surface can trigger the transmission of various types of indicator parameters, with different type point configurations for multiple access points. In the synchronization platform, the parameter values ​​are also configured for the receiving trigger surface, which consists of multiple access points, which are also storage points (addresses). Each access point is configured with different types of points, consistent with the transmission trigger surface. Each access point is connected to a receiving point, which is a virtual machine configured in the synchronization platform for connection. Thus, once the corresponding access point of the transmission trigger surface trigger packet is in place and connected to the channel, the channel is immediately opened. Each access point in the receiving trigger surface has parameter values ​​configured for multiple types of points in the corresponding transmission trigger surface. The only difference between the transmission and receiving trigger surfaces is that the receiving trigger surface already has connected receiving points. Therefore, besides the receiving point, only one distance needs to be selected here. For example, if there are two types of indicator parameters, A and B, with value ranges of 1 and 2 and 5 and 6 respectively, then there are two access points. This is a distance explanation; if the value range is large, then there are more corresponding access points.There is a one-to-one correspondence between access points and numerical parameters. Therefore, there are multiple access points on the transmission trigger surface, each corresponding to two type points, A and B respectively. The receiving trigger surface also has type points A and B. This is equivalent to both the transmission and receiving trigger surfaces having two access points, each with two corresponding type points A and B. Then, two channels are set up between the transmission and receiving trigger surfaces, corresponding to the number of each type point for each of the two access points. There is a one-to-one matching relationship between the two channels and their corresponding type points. Next, the multiple types of index parameters collected from the acquisition points are extracted for type and specific parameters. For example, for type A, value 1, a trigger packet stored in a conversion area is randomly selected to wrap and mark the data. The trigger packet is then sent to the access point with the corresponding parameter and type. Because there is an access point corresponding to type A, value 1, the access point is then triggered. Packet binding is performed, and the trigger packet establishes a connection with the channel and activates it. Activating the channel is equivalent to transmitting data. The trigger strength varies for each channel type, allowing for the determination of the corresponding data type and ensuring accurate data transmission. Immediately after triggering, the trigger packet is disconnected from the access point, and the parameter values ​​in the trigger packet are marked, eliminated, and re-stored in the conversion area for later use. Continuous acquisition and transmission are possible without interruption. No data transmission is required; information transmission only requires channel activation via the docking channel. Transmission is pre-configured at both ends of the channel, saving on data transmission steps and bringing data acquisition and analysis closer to synchronous performance. This improves the timeliness of data transmission and enables more timely feedback on power system clock synchronization anomalies, reducing their impact on the power system.

[0025] In one embodiment, the execution module includes: The analysis unit is used to classify and analyze the collected multi-dimensional indicators. When the indicator data does not meet the preset conditions, it is considered an abnormal situation. The matching unit is used to create an execution matching library. The execution matching library includes abnormal situations and the execution tasks for abnormal situations. Abnormal situations where the indicator data does not meet the preset conditions are matched with corresponding execution tasks through the execution matching library. The abnormal issues are managed in a hierarchical manner based on the execution tasks.

[0026] In one embodiment, the matching designation unit further includes: The database management unit is used to store historical data on abnormal situations and hierarchical switching execution based on big data collection to obtain an execution matching library; The connection unit is used to connect the execution matching library with the synchronization platform.

[0027] It should be noted that real-time monitoring includes the rubidium atomic clock's discipline status, the number of locked satellites (≥4), and output signal accuracy (PPS deviation ≤30ns). Transmission delay jitter is monitored, with an alarm triggered if it exceeds 200ns. Satellite lockout ≤30 minutes is also considered an abnormal situation, representing historically possible issues. Specifically: for example, transmission delay jitter exceeding 200ns; trigger condition: the TMU monitoring board detects main link delay jitter >200ns, the alarm light is solid yellow, and the log records an abnormal transmission channel. Handling steps: Step 1: Check the specific jitter value and the faulty channel (e.g., main link fiber FIBER1). Step 2: Manually enable the backup link by entering output selection – fiber optic expansion board configuration, and switching the signal output to the backup port. Step 3: Check the cause of the main link fault (e.g., fiber damage, loose interface) and repair it. Afterward, recalibrate the main link delay compensation value (in ns). After testing and confirming jitter ≤200ns, the main link can be switched back. The above describes an abnormal situation and corresponding actions in the execution matching library. In other cases, such as satellite loss of lock (number of locked satellites < 4), a satellite loss of lock timer is initiated. The tiered processing steps are as follows: First stage (loss of lock ≤ 30 min): Rubidium atomic clock timekeeping is performed: The device automatically switches to the internal reference of the rubidium atomic clock. The timekeeping accuracy of the rubidium atomic clock is monitored, checking for accuracy ≤ 1 μs / hour. If this is exceeded, the rubidium atomic clock's discipline status is checked to ensure it is "disciplined." Continuous attempts to reconnect to the satellite are made: The device automatically scans for satellite signals. If lock is restored within 30 min (number of locked satellites ≥ 4), the device automatically switches back to the satellite time source to calibrate the rubidium atomic clock. Second stage (loss of lock > 30 min): Switching to the IRIG-B (DC) time source is initiated. The log records that the satellite time source is unavailable, and the device switches back to IRIG-B (DC). Automatic switching logic: Based on preset priority (rubidium atomic clock - satellite - IRIG-B(DC)), the ground time source is used as the calibration reference, while the rubidium atomic clock remains the internal timekeeping reference. It receives IRIG-B(DC) signal discipline. This is the second abnormal situation and corresponding execution procedure. The distance description for some abnormal situations is provided here; the actual state can be configured with multiple schemes based on common abnormal problems. Post-switching verification: Enter device status - IRIG-B1 / IRIG-B2 status, confirm that the synchronization status is synchronized, the channel difference is ≤100ns, and the output signal accuracy (PPS deviation ≤30ns) meets the requirements. During the final signal accuracy verification after the switch, the output signal is tested using a time tester to ensure that the PPS deviation is ≤30ns, the IRIG-B code output accuracy is ≤1μs, and the NTP / SNTP accuracy is ≤10ms. System status confirmation: Check device status - power status, fault status. There are no abnormal alarms, and the time difference of all terminal devices (such as PMU, fault recorder) is ≤1μs. Satellite time source recovery: When the number of satellites locked on is ≥4 and remains stable for 5 minutes, the device automatically switches back to the satellite time source and re-tames the rubidium atomic clock until the taming level is ≥5 / 5.Primary Link Recovery: After repairing the primary link, confirm that the transmission delay jitter is ≤200ns, switch back to the primary link, and keep the backup link in standby mode. Export the logs during the anomaly (including lockout time, switchover time, and various indicator data) and archive them for future reference. For frequent switchover failures, analyze the root cause (such as satellite antenna interference, unstable ground time source), and optimize deployment or parameter configuration.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
