In recent years, China National Grid has been striving to build a strong and intelligent grid with network and automation. It has already clarified the strategy of promoting the development of strong smart grids in stages and the construction plan of strong smart grids in the next decade. An important aspect of grid transformation and strong smart grid construction is to strengthen the network's self-diagnosis, protection and self-healing functions. Power companies need power line monitoring and protection systems to monitor and control energy consumption, cost and quality, and Protects expensive equipment so that it is not damaged by surges and harsh weather.

Relay protection is an important technology to realize and monitor and protect related equipment. The development of computerization, networking, intelligence, and integration of protection, control, measurement and data communication is a long-term development trend in this field. This puts new requirements on the new generation of relay protection scheme platform: higher relay protection performance; system hardware and software expansion capability; higher reliability.
ADI's relay protection solution platform uses the Blackfin processor (ADSP BF518) and the new synchronous sampling ADC (AD7606), which are currently widely used in power line monitoring systems. The solution provides complete hardware and software modules, freeing users from software development such as hardware platform, operating system, protocol stack and GUI, greatly shortening the product development cycle and reducing the difficulty of software and hardware development. (The reference design has completed nearly 60% to 70% of the development task of the complete relay protection product. The customer only needs to complete the remaining application development based on the platform, which greatly shortens the product development cycle.)
