Abstract :
This paper discusses transient fault current characteristics of photovoltaic system with the help of photovoltaic power system simulation model built in the PSCAD/EMTDC. Then analyze the characteristics and problems of typically existing relay protection configuration scheme for photovoltaic power station and its outgoing lines, and puts forward corresponding improvement measures.
