On the basis of analyzing research status quo and future developing trend of switching power supply in closed loop, this paper states connotation and meaning of switching power supply in closed loop of regional power grid and summarizes basic types of it as off-line closed loop,on-line closed loop and closed loop based on state estimation. In aspects of external equivalence of regional power grid and closed loop feeder current calculation,it summarizes basic computing methods for each closed loop and points out different applicative conditions which may provide theoretical basis for further research on switching power supply in closed loop.
