A Study on Enhancing the Total Transfer Capability from Voltage Stability Point of View Using UPFC

IPLAN을 이용한 UPFC 적용 전력시스템의 전압 안정도 측면에서의 융통전력 향상 효과 분석

Using UPFC(Unified Power Flow Controlled), it is possible to control three parameters(voltage, impedance, and phase angle). The UPFC can generate or absorb reactive power rapidly so as to enhance the transient and voltage stability and also influence the power flow. In this paper, the effects of application of the UPFC to the power system are analyzed from a viewpoint of improving the total transfer capability by enhancing voltage stability. The IPLAN, which is a high level language used with PSS/E program, is employed for evaluating the total transfer capability from a f-V curve.
