Technical Field

[0001] This utility model relates to the field of power grid equipment technology, specifically a power grid clock synchronization device. Background Technology

[0002] In power grid systems, time synchronization is crucial for stable operation and fault diagnosis.

[0003] Traditional power grid clock synchronization devices typically rely on external clock sources, such as satellite signals or Network Time Protocol (NTP) servers. However, these methods have several limitations. For example, satellite signals may be blocked or interfered with in some areas, leading to a decrease in clock synchronization accuracy. Network latency and jitter of NTP servers can also affect clock synchronization accuracy. Furthermore, the widespread distribution of equipment in a power grid system and the varying clock synchronization requirements among different devices make it difficult for traditional clock synchronization devices to meet these complex needs. Therefore, a power grid clock synchronization device is needed to address these issues. Utility Model Content

[0028] A power grid clock synchronization device includes a main body 1, a master clock module 2 disposed on the side of the main body 1, a slave clock module 3 fixedly connected to the side of the master clock module 2, and a communication module 4 and a synchronization control and power supply module assembly 5 fixedly connected inside the main body 1.

[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the master clock module 2 includes a high-precision atomic clock 201. A satellite signal receiving module 202 and a clock storage unit 203 are fixedly connected to the side of the high-precision atomic clock 201. The slave clock module 3 includes a mounting plate 301. A clock receiving unit 302, a clock adjustment unit 303, and a clock feedback unit 304 are fixedly connected to the side of the mounting plate 301. The communication module 4 includes a support plate 401. An optical fiber communication unit 402, a wireless communication unit 403, a power line carrier communication unit 404, and a communication protocol conversion unit 405 are fixedly connected to the side of the support plate 401. The synchronization control and power supply module assembly 5 includes a carrier plate 501. A dynamic adjustment unit 502 and a fault detection unit 503 are fixedly connected to the side of the carrier plate 501. By using the high-precision atomic clock 201 as the clock source and calibrating it through the satellite signal receiving module 202, the high precision and stability of the master clock are ensured. The slave clock module 3 adjusts according to the clock signal of the master clock module 2 to achieve high-precision clock synchronization of the entire power grid system.

[0030] Among them, the satellite signal receiving module 202 and the clock storage unit 203 are electrically connected; the clock receiving unit 302, the clock adjustment unit 303 and the clock feedback unit 304 are all electrically connected; the optical fiber communication unit 402, the wireless communication unit 403, the power line carrier communication unit 404 and the communication protocol conversion unit 405 are all electrically connected; and the dynamic adjustment unit 502 and the fault detection unit 503 are electrically connected. The communication module 4 employs multiple communication methods, including optical fiber communication, wireless communication and power line carrier communication, to adapt to different power grid environments and equipment distributions. The fault detection unit 503 of the synchronization control module can monitor communication faults and clock deviation anomalies in real time, and activate the backup clock source or issue an alarm signal when a fault is detected, thereby improving the reliability of the device.

[0031] In this embodiment, as Figure 1 and Figure 3 As shown, the main body 1 includes a base plate 101, with four mounting holes 102 inside the base plate 101. A support rod 103 is fixedly connected to the top of the base plate 101, and a loading box 104 is fixedly connected to the top of the support rod 103.

The calibrated clock information is stored in the clock storage unit 203. The master clock module 2 sends the clock signal to the slave clock module 3 through the communication module 4. The communication module 4 selects an appropriate communication method according to the power grid environment and equipment distribution, and converts the clock signal into a suitable format through the communication protocol conversion unit 405. The clock receiving unit 302 of the slave clock module 3 receives the clock signal sent by the master clock module 2. The clock adjustment unit 303 adjusts the local clock according to the received clock signal, and feeds back the synchronization status of the local clock to the master clock module 2 through the clock feedback unit 304. The synchronization control module dynamically adjusts the clock signal transmission frequency of the master clock module 2 and the clock adjustment strategy of the slave clock module 3 according to the synchronization status information fed back by the slave clock module 3, so as to ensure the clock synchronization accuracy of the entire power grid system. The fault detection unit 503 of the synchronization control module monitors the communication faults and clock deviation anomalies between the master clock module 2 and the slave clock module 3 in real time, and starts the backup clock source or issues an alarm signal when a fault is detected.
