China Mobile, NR Electric, and ZTE Corporation have jointly released the industry's first end-to-end 5G TSN deterministic network.
Supporting grid services such as grid differential protection, the network accelerates the deployment of renewable energy sources such as solar energy and wind energy while empowering green grids, said a press release from ZTE, the international provider of telecommunications, enterprise, and consumer technology solutions.
According to the release, the end-to-end 5G TSN deterministic network can effectively solve the network latency and jitter problems caused by traffic conflicts. Combined with the slicing technology and the technology of separating forwarding from control, the determinacy of the power grid is guaranteed fundamentally and the security and stability of the power grid are assured.
Moreover, the network, adopting wireless congestion control and scheduling algorithms, intelligent scheduling data forwarding, and queue management in the core network, can greatly reduce 5G end-to-end latency, it said.
In addition, the technologies such as wireless dual-link, end-to-end frame replication and elimination (FRER), as well as network dual-tunnel are utilized to meet the demanding requirements for reliability of the power grid.
And the industry's first TSN hardware acceleration card provides real-time traffic identification and forwarding, traffic shaping, and high-precision clock synchronization, which ensures that the time latency, jitter, and time synchronization can meet the synchronization requirements of the sampling data on the differential protection device.
The company states that 5G TSN deterministic network, replacing optical fiber cables, allows flexible access to the last mile and significantly reduces the cost of communication network constructions. 5G TSN can be widely used in power service scenarios such as grid differential protection, power distribution automation, phasor measurement unit (PMU) and accurate grid load scheduling.
While accelerating the deployment of new energy such as solar energy and wind energy, it achieves efficient coordination of various types of energy resources including wind, solar, water, thermal, and storage, to promote the strategic goal of "emission peak, carbon neutrality".
