摘要：
The structure of conventional distribution system is radial, and overcurrent relays are widely used as primary protection. When a large number of distributed generations (DGs) are introduced, the system becomes an active distribution network. It is necessary to study new protection schemes applicable to active distribution network. This paper proposes a pilot protection scheme for active distribution network considering branches. The relationship of current phase variation direction and load power flow direction are used to build a criterion. Simulation results show the protection scheme can accurately identify the faults.
