Abstract: The electric power system communication network is an important infrastructure. At present, it is mainly builded with traditional SDH/MSTP technology. With the intelligent power grid requirements, the traditional optical network is no longer able to adapt to the fast growing electric power system service requirements. Thus, the intelligent optical network is coming,ASON represents the developing direction, and it can solve the bandwidth for rapid deployment, end to end configuration and service protection/restoration and other issues, which provides reliable network control capabilities. This paper discussed the application of China Southern Power Grid Company by using the protection/restoration mechanism service intelligence technology of ASON intelligent optical network to achieve power service self-healing of anti-multi-point malfunction,which has improved the reliability of the network, and laied the foundation for the intelligent communication network for the next step.
