Abstract
The Japanese power system is divided into 50Hz and 60Hz systems, which are interconnected by power electronics based frequency converter station. Frequency converter can be realized by using Adjustable Speed Generator/Motor(ASGM), which is excited by AC voltage. This frequency converter can also work as power system stabilizer. In this study, control systems for power interchange are designed based on eigenvalue control technique, and it is made clear that 300[MW] reverse power interchange can be achieved quickly and smoothly. Next, power system stabilizing control systems are also designed based on eigenvalue control technique or energy function, and control performances of these control systems are shown for a model system.
