This paper presents a chip-based relay protection technology based on system-on-chip (SoC), which is described from four aspects, namely, the architectural design of the relay protection SoC, software and hardware cooperative relay protection based on the SoC IP core . These clean energy sources, connected through inverters and flexible transmission systems, are transforming traditional grids based on synchronous generators into more flexibl cant challenges to system stability. The relay protection device is the core equipment that ensures the safe and stable operation of a power grid. With the development of new power systems and the continuous increase in the proportion of new energy installed capacity, the application scale of power electronic equipment as a means to support renewable energy grid connection, transmission and flexible control is constantly expanding.

Optical Line Protection (OLP) is a device designed specifically for ensuring the resilience of these network transmission lines. Optical Transport Network (OTN) serves as the backbone of modern communication infrastructures. It encompasses a complex architecture comprising optical channels, multiplex sections, and transport sections. Key elements of OTN include: Standardized framing (the "digital wrapper"): OTN adds overhead. Tunnel APS is classified into 1+1 protection and 1:1 protection by protection mechanism.
