An adaptive reclosing system considering distributed generation is provided to enhance reliability of supply in a power distribution system by determining a recharging time of the distribution generation according to variation of a voltage and a frequency of the power distribution system after reclosing. An adaptive reclosing system considering distributed generation(50) includes a kinetic energy calculating unit(60), a potential energy calculating unit(70), an energy function calculating unit(80), and a reclosing relay(30). The kinetic energy calculating unit detects kinetic energy by using data of the distributed generation. The potential energy calculating unit detects potential energy by using a voltage of a bus bar and a current and a voltage flowing at a switch of a lower end of an error generation area. The energy function calculating unit calculates an energy function by outputs of the kinetic energy calculating unit and the potential energy calculating unit. The reclosing relay controls first and second circuit breakers according to an output of the energy function calculating unit, the voltage of the bus bar, and the current and the voltage flowing at the switch.
