要約(日本語): Traction loads in AC railways have been increasing in many developing countries as well as developed countries. Some countries electrify their own conventional lines receiving power from weak power systems, then voltage unbalance and other power quality issues are arisen. Compensation devices or power conditioners have been, therefore, introduced for electric railway applications. The static railway power conditioner (RPC) is one of those compensators and proposed in this paper to exhibit its mathematical model using two current sources incorporated into two secondary supply sides of the AC railway power feeding substation. The model is capable of independently varying the modulation indexes and phase angles of both converters’ output voltages to estimate the voltage unbalance at the point of common coupling. Five test cases are applied to the model to investigate its effectiveness.
