Patent number: 10120953Abstract: The present invention relates to a system data abbreviation system and method. The system data abbreviation system includes a data mapping unit configured to classify system data, provided by an external database, into classes of a database of an internal application program and to then map the classified system data; a data search unit configured to search for data of the class to be abbreviated from the database of the application program; and a data abbreviation unit configured to group the found data of the class, to set link relations between data that belongs to the group, to set link relations between the group and the classes of the database of the application program, and to then abbreviate the data.Type: GrantFiled: October 4, 2012Date of Patent: November 6, 2018Assignee: Korea Electric Power CorporationInventors: Cheol-Min Chu, Sang-Yun Yun, Seong-Chul Kwon, Il-Keun Song

Patent number: 9594389Abstract: 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.Type: GrantFiled: September 30, 2011Date of Patent: March 14, 2017Assignee: KOREA ELECTRIC POWER CORPORATIONInventors: Cheol-Min Chu, Sang-Yun Yun, Seong-Chul Kwon, Il-Keun Song
