| Research Abstract |
This research report presents a fast transmission power control scheme of a UPFC(Unified Power Flow Controller) using the small capacity converters under the output voltage saturation for the practical use. The following results are obtained in this research.
1.For the development of the fast transmission power control scheme of the UPFC using the small capacity converters under the output voltage saturation, the models of the power transmission system and UPFC are derived. The control scheme of the transmission power under the output voltage saturation in steady state is derived.
2.For the stability of the transmission control under the ground fault, the models of the power transmission system under the ground fault are derived. The control scheme of the UPFC under the ground fault is proposed. The simulation has verified the stability of the control scheme.
3.In the converter capacity of the UPFC for the transmission control in the loop transmission system, the theoretical rated values of the voltage and current are shown. The optimum setting point of the UPFC is the line of the lowest current.
4.The fast and stable power responses are realized in the transient and steady states by the experiments using the three-phase, 200V and 7kW laboratory prototype of the UPFC,
