“…Furthermore, the 3GPP R16 standard incorporates time-sensitive networking (TSN), a time-sensitive Ethernet data transmission mechanism defined by the IEEE 802.1 working group, characterized by low latency and low jitter, into 5G. The R17 standard proposes an enhanced TSN architecture [20]. The seamless integration of TSN wired networks with 5G wireless networks [21,22] further reduces latency, achieving an end-to-end latency of approximately 15 ms in 5G networks.…”

To enhance the reliability of traditional current protection systems in the evolving landscape of future power grids, this paper proposes a differential protection data synchronization approach that leverages satellite and 5G network timing. This method addresses the risk of inadvertent operation due to 5G communication jitter. It employs the BeiDou satellite system for synchronizing the timing of 5G base stations and terminals. This synchronization extends to the 5G terminal and the protection device, thereby mitigating time deviations caused by air interface delays and reducing the 5G network’s end-to-end delay by approximately 4 ms on average. A simulation was conducted to assess the reliability and effectiveness of the proposed method under normal satellite signal conditions. The results indicated a significant improvement in protection accuracy, with the method reducing the protection activation time by approximately 5–7 ms compared to the 5G timing data synchronization method. This advancement offers technical support for the safe and stable operation of new power systems.

“…Their technique causes significant overhead over the wireless medium and is not suitable to satisfy the synchronisation requirements of 5G, notably the 900 ns [1]. In [2], the authors introduced a propagation delay estimation and compensation technique which combines both TA and RTT methods. They talked about the downlink/uplink time synchronization budget from a RAN perspective.…”

The growing needs for wireless connectivity in smart industries raises opportunities for mobile service providers as well as industrial players, also known as verticals. This inevitably has increased challenges for both the parties involved. This is increasingly true for timing and synchronization requirements. Within this context, in this article, we present a detailed analysis of 'time synchronization errors'. These errors are commonly known to affect the delivery of accurate time needed to synchronize the robots and machines present inside the Industrial Internet of Things (IIoT) domain. To eliminate such errors, we propose a novel compensation technique to compensate for the random errors which occur due to the propagation delay in the wireless medium. The article concludes by providing numerous results based on simulations with discussions proving the efficacy of our proposal.
