DEVICE AND METHOD FOR AUTOMATICALLY COORDINATING PROTECTION DEVICE OF SMART POWER DISTRIBUTION MANAGEMENT SYSTEM

摘要

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 (that is, power flow analysis, failure 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 of a smart power distribution management system as provided comprises: generating the topology information of the distribution system by obtaining the status information of the distribution system; setting at least one or more machines, which transmit and received data when an event in the distribution system is generated, to communicate for each of a plurality of protection devices based on the generated topology information; calculating a system power flow including the power flow direction of the distribution system 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.
