Challenges:

Smart grids require widely distributed μs-level synchronization accuracy to ensure relay protection and new energy grid connection safety.

Solution:

• Core technology: optical fiber time and frequency transmission equipment (phase jitter <1ps) + BDS/GPS dual-mode redundant timing.

• Applicable products: power synchronization clock, time monitoring terminal, optical fiber time and frequency distribution amplifier.

• Scenarios: UHV power transmission, wind power/photovoltaic grid connection, microgrid control.

• Customer value: wide-area synchronization error <1μs, fault location accuracy increased by 90%.
