Abstract :
This paper describes the effort of the Korea Electric Power Co. to develop a wide area monitoring system (WAMS) and online transient and voltage security assessment tools. The master system of the WAMS at the Control Center monitors at a 10 Hz sampling rate the important system conditions transmitted from 24 local measurement units installed at major generating stations and substations. Each local unit monitors two 3-phase bus voltages and 3-phase currents of fourteen feeders at the 7680 Hz sampling rate.
