Application of Intelligent Voltage Control System to Korean Power Systems

摘要

The Korea power system has been operated more closely to stability limits in state heavy-load because of growth in load-demand and the reactive power loss have been increased due to the installation of long-distance transmission lines, since the power plants are located far from load-demand regions. The voltage collapse can be caused by reactive power unbalance. Some advanced countries experienced massive blackout due to voltage collapse. In order to solve voltage problems, several advanced countries are operating voltage and reactive power control system by taking into account the inherent characteristic of their individual power system. Recently, secondary control system and intelligent control system for Jeju power system have been reported in Korea. But voltage control system about mainland power system has not been reported. This paper presents the applicability of intelligent voltage control system for Korean power systems.
