한국형 고속열차 주행에 따른 전철변전소 전력공급 상태에 관한 연구

초록

PCC(Point of Common Coupling) is measured by waveform in power system. Analyzing their frequency, it is possible to get various indices such as THD(Total Harmonic Distortion), TDD(Total Demand Distortion), and VF(Voltage Flicker), and then the harmonic can be evaluated from them. In this paper, the harmonic effect on the power supply which is generated by the vehicle is presented by comparing harmonics with the substation and the vehicle.
