Abstract :
The high speed phase shifter (HSPS) presented here is composed of three sets of a single phase PWM inverter which are connected in series to a power system, and another PWM inverter to control the DC link voltage of inverters at a specified value which is connected in parallel to a power system. The configuration is same as a UPFC (unified power flow controller). The experimental mini model for 10 kVA transmission line was developed and its performance for power system stabilizing control was examined. It was shown that not only transient stability but also dynamic stability can be improved by the HSPS
