Under the rapid development of power electronics technology, AC/DC hybrid power supply can be used to comprehensively solve the demand for source and supply.The article takes the first comprehensive demonstration project of the dual-stage AC-DC hybrid system based on multi-function power electronic transformer cluster in China as the research object.A distributed renewable energy system simulation platform with AC/DC hybrid is established in the hardware RTDS to simulate and analyze the fault characteristics under different conditions.Based on the fault characteristics and the principle of protection division, in order to ensure that the ranges between the protection zones overlap each other and cover the entire AC-DC distribution network,This paper studies the specific protection zones and configurations for the industrial park system, and has developed a comprehensive protection configuration plan.
