With regard to the research status and exiting problems, this paper proposes some suggestions. Then from the application aspect, both the system structures and the division methods for information domain in the wide-area relaying protection system are expounded. How to realize system fault-tolerance and optimization based on wide-area redundant information is also discussed. The paper finally investigates how to apply related information technologies such as IEC61850 standard, multi-agent technology and grid computing technology to the wide-area relaying protection system. Wide area information based wide-area protection, which achieves both the relay protection and stability control, has become the central issue of modern power system research, and will be the futu
