PROBLEM TO BE SOLVED: To estimate a trolley voltage value with high precision based upon a tertiary voltage value of a transformer.SOLUTION: A voltage conversion controller 35 detects a tertiary voltage value V3, a tertiary current value I3, and a secondary current value I2, and estimates a trolley voltage value V1 based upon respective detection values thereof. Specifically, a storage part 42 is stored with correlation information representing correlation between a ratio of the trolley voltage value V1 and tertiary voltage value V3, and the secondary current value I2. The power conversion controller 35 uses the correlation information stored in the storage part 42 to estimate the trolley voltage value V1 from the respective detection values V3, I3 and I2.SELECTED DRAWING: Figure 1

    【課題】変圧器の3次電圧値に基づいて高い精度で架線電圧値を推定できるようにする。【解決手段】電力変換制御装置35は、3次電圧値V3、3次電流値I3及び2次電流値I2を検出し、これら各検出値に基づいて、架線電圧値V1を推定する。具体的に、記憶部42には、架線電圧値V1と3次電圧値V3の比率と、2次電流値I2との相関関係を示す、相関情報が記憶されている。電力変換制御装置35は、記憶部42に記憶されている相関情報を用いて、上記各検出値V3、I3、I2から架線電圧値V1を推定する。【選択図】図1
