AI Technical Summary
Existing substation wireless communication systems struggle to quantitatively predict and finely control the signal-to-noise ratio of communication links in environments with strong electromagnetic interference, leading to problems such as increased communication delays, higher energy consumption, and link instability.
A coupling model between electromagnetic disturbance and communication link is established. By collecting multi-source disturbance signals to construct a disturbance state vector, communication parameters are jointly optimized to improve the signal-to-noise ratio.
It achieves a coordinated improvement in the signal-to-noise ratio of wireless communication under strong electromagnetic interference environment, avoids the problems of increased communication delay and system instability, and improves the reliability and stability of communication link.
