【 摘 要 】

With the continuous expansion of power grid, traditional protection strategies based on the local information can no longer meet the needs of the safe and stable operation of complex power systems, and it is necessary to establish a high-speed, real-time, safe and reliable power communication network to support AC/DC co-control, disconnect control, precise load shedding, and panoramic state awareness and other system protection functions. This paper designs a communication network simulation system for system protection services. It describes the system from both functional architecture and software architecture and analyzes the system protection business requirements, including the bandwidth requirements and the delay requirements based on existing communication technologies. The communication scheme based on MSTP and OTN is verified by simulation. and it provides a good basis for the planning and construction of system protection.
