Abstract
Supervisory Control And Data Acquisition(SCADA) of electric power system refersto the system that displays, monitors and executes the control commands for remote electric power system. KNR's existing electric power control system is built on UNIX platform such that it costs more for system construction, and people with UNIX skills can only be an operator who controls and manages the system. Moreover, since the system is mainly operated in local offices, system operators must communicate with local operators to investigate the cause of the accident and react the accident every time the system fails. As a new integrated SCADA system is constructed, establishment of small-unit electric power control system, that alters local electric power control system in designated stations, is required. In this study, the electric power control system, which accommodates all functions of UNIX-based SCADA system and facilitates operation and even maintenance for local operators, is to be developed. In order to develop small-unit electric power control system, the industrial automation program, "Cimon", is used. The small-unit electric power control system that accommodatesRTU and newly installed electronic switchboard is being developed and tested at Chulam station of KNR.
