Abstract
Provided are a device and a method for automatically coordinating a protection device of a smart power distribution management system, wherein a protection coordination correction value of the protection device is calculated via topology analysis and system analysis of a distribution system so as to apply the result to a smart power distribution management system. The device for automatically coordinating a protection device as provided comprises: generating the topology information by obtaining the status information of the distribution system; setting machines, which transmit and received data when an event occurs, to communicate for each of a plurality of protection devices based on the topology information; calculating a system power flow including the power flow direction based on the topology information; and calculating a fault current which is generated upon the failure of the distribution system based on the topology information, thereby generating a protection coordination correction value.
