A Study on the Validation of Reactive Power and Regenerative Power Control Performance of an AC Railway Power Conditioner Through Field Testing

In the AC electric railway, reactive power is generated due to the inductive characteristics of the vehicle load and the capacitor bank. When the power system supplies reactive power, a penalty is incurred due to a low power factor. In addition, regenerative power is generated when braking a railroad vehicle, and electricity rates can be reduced if it is controlled and used as load power. This paper verifies the effectiveness through on-site test data that controls the reactive power generated when operating a railway vehicle through RPC, reduces the reactive power supplied by the power system, and controls the regenerative power and utilizes it as load power.
