要約(英語): In our previous study, we developed the fixed power factor output method voltage control with reference voltage command value adjustment. This control method enables electronic frequency converters, interconnected to a distant power source, to appropriately share the power supply of the train load. However, we confirmed that overvoltage in line and phase voltage can occur when large unbalanced power flows from the distant power source, and this control method cannot suppress the unbalanced power. Therefore, in this study, we developed the fixed power factor output method voltage control with reference voltage command value adjustment adding unbalanced power suppression function, which we verified with power system analysis.
