According to one embodiment of the present invention, provided is a real-time catenary line impedance measurement system. The real-time catenary line impedance measurement system comprises: a first measuring device disposed at a first point of a power supply system to measure a voltage and a current; a second measuring device disposed at a second point of the power supply system to measure a voltage and a current; and an impedance calculation unit configured to calculate an impedance of a catenary line in a section positioned between the first point and the second point based on the voltage and the current measured by the first and second measuring devices, respectively. The impedance calculation section of the catenary line includes a section in which an electric car is placed as a load. Measurement points of the first measuring device and the second measuring device are synchronized.
