Description

本発明の実施形態は、電気車制御装置に関する。 Embodiments described herein relate generally to an electric vehicle control apparatus.

車両内に搭載されている電気車制御装置は、高電圧配線を介して車両外のパンタグラフと接続される。パンタグラフは変電所と接続され、変電所からの直流電力はパンタグラフ、高電圧配線を通して電気車制御装置に供給される。電気車制御装置は供給された直流電力を車両走行可能な交流電力に変換する。車両の走行中、上記の高電圧配線が何らかの原因によって、電気車制御装置の筐体に接触すると、その接触部分を介して短絡が起こり、地絡事故が発生することになる。車両の走行中に、地絡や短絡時に発生する事故電流により変電所を停止させる恐れがあるため、事故電流発生時は車両に搭載された遮断器で故障回路を開放している。しかし、車両に搭載された遮断器では遮断時間によっては変電所をトリップさせることがある。事故電流を高速に遮断するため、遮断器に半導体を適用し、遮断速度の向上を図った電気車制御装置の提案がなされている。 The electric vehicle control device mounted in the vehicle is connected to a pantograph outside the vehicle via a high voltage wiring. The pantograph is connected to the substation, and DC power from the substation is supplied to the electric vehicle control device through the pantograph and the high voltage wiring. The electric vehicle control device converts the supplied direct current power into alternating current power that allows the vehicle to travel. When the high-voltage wiring contacts the casing of the electric vehicle control device for some reason while the vehicle is running, a short circuit occurs through the contact portion, and a ground fault occurs. While the vehicle is running, there is a risk that the substation may be stopped by an accident current that occurs when a ground fault or short circuit occurs. Therefore, when the accident current occurs, the fault circuit is opened with a circuit breaker mounted on the vehicle. However, the circuit breaker installed in the vehicle may trip the substation depending on the interruption time. In order to cut off the accident current at high speed, an electric vehicle control device has been proposed in which a semiconductor is applied to the circuit breaker to improve the breaking speed.

FIG. 1 shows a DC power source 100, a charging resistor 101, a semiconductor breaker 102, a voltage detector 103 for a semiconductor breaker, a current detector 104, a charging capacitor 105, a voltage detector 106, a power conversion circuit (or load) 107, The main ground 108, the control unit 1000, the current value calculation unit 1001, the gate command output control unit 1002, the voltage value calculation unit 1003, the current value comparison unit 1004, and the semiconductor breaker failure determination unit 1005 are configured.

電源１００と半導体遮断器１０２は直列接続される。半導体遮断器１０２と充電抵抗器１０１は並列に接続され、半導体遮断器１０２と半導体遮断器用電圧検出器１０３は並列接続される。半導体遮断器１０２と電力変換回路（または負荷）１０７のプラス側は、電流検出器１０４を介して接続される。半導体遮断器１０２側で電力変換回路（または負荷）１０７と充電用コンデンサ１０５は並列に接続される。電力変換回路（または負荷）１０７のマイナス側で、電源１００と充電用コンデンサ１０５の間に主接地１０８が接続される。また、半導体遮断器１０２、半導体遮断器用電圧検出器１０３、電流検出器１０４、電圧検出器１０６は制御部１０００と接続される。 The power supply 100 and the semiconductor circuit breaker 102 are connected in series. The semiconductor circuit breaker 102 and the charging resistor 101 are connected in parallel, and the semiconductor circuit breaker 102 and the semiconductor breaker voltage detector 103 are connected in parallel. The plus side of the semiconductor circuit breaker 102 and the power conversion circuit (or load) 107 is connected via the current detector 104. On the semiconductor circuit breaker 102 side, the power conversion circuit (or load) 107 and the charging capacitor 105 are connected in parallel. A main ground 108 is connected between the power source 100 and the charging capacitor 105 on the negative side of the power conversion circuit (or load) 107. Further, the semiconductor circuit breaker 102, the semiconductor circuit breaker voltage detector 103, the current detector 104, and the voltage detector 106 are connected to the control unit 1000.

制御部１０００の電流値演算部１００１は、電流値比較部１００４と接続され、電流値比較部１００４と電圧値演算部１００３と接続されるゲート指令出力制御部１００２が半導体遮断器故障判定部１００５と接続される。電流値演算部１００１は電流検出器１０４から電流値を演算し、半導体遮断器故障判定部１００５は、電圧値演算部１００３からの電圧値より半導体遮断器１０２のゲート指令出力を制御するゲート指令出力制御部１００２のゲート指令出力状態および電流値比較部１００４の比較結果から、半導体遮断器１０２の故障を判定する。 The current value calculation unit 1001 of the control unit 1000 is connected to the current value comparison unit 1004, and the gate command output control unit 1002 connected to the current value comparison unit 1004 and the voltage value calculation unit 1003 is connected to the semiconductor breaker failure determination unit 1005.

（作用）
本実施形態の作用について図１を参照して説明する。半導体遮断器１０２がオフ（不導通）しているとき、電源１００からの電力は、充電抵抗器１０１を介して、充電用コンデンサ１０５に供給される。充電用コンデンサ１０５の充電が完了すると、半導体遮断器１０２がオン（導通）し、充電抵抗器１０１が短絡されるため、電源１００からの電力は半導体遮断器１０２を通り、電力変換回路（または負荷）１０７に供給される。例えば車両では、電源１００からの直流電力は、半導体遮断器１０２、電流検出器１０４、充電用コンデンサ１０５を介して電力変換回路へ供給され、電力変換回路では車両を走行させるための３相交流電力に変換し、電動機へと出力する。 (Function)
The operation of this embodiment will be described with reference to FIG. When the semiconductor circuit breaker 102 is off (non-conducting), power from the power source 100 is supplied to the charging capacitor 105 via the charging resistor 101. When the charging of the charging capacitor 105 is completed, the semiconductor breaker 102 is turned on (conducted) and the charging resistor 101 is short-circuited, so that power from the power supply 100 passes through the semiconductor breaker 102 and passes through the power conversion circuit (or load). ) 107. For example, in a vehicle, DC power from a power source 100 is supplied to a power conversion circuit via a semiconductor circuit breaker 102, a current detector 104, and a charging capacitor 105, and the power conversion circuit uses three-phase AC power for driving the vehicle. And output to the motor.

しかしながら、半導体遮断器１０２が故障した場合は、故障の検出をする必要があるため、半導体遮断器１０２が故障しているかどうかを知る手段が必要となる。 However, when the semiconductor circuit breaker 102 fails, it is necessary to detect the failure, so a means for knowing whether the semiconductor circuit breaker 102 is broken is necessary.

そのため以下に、電流遮断に用いる半導体遮断器の健全性を確認する手段について、図１、図２、図３を参照して説明する。 Therefore, hereinafter, means for confirming the soundness of the semiconductor circuit breaker used for current interruption will be described with reference to FIGS. 1, 2, and 3.

図２に示すように、電流検出器１０４の検出値より、電流値演算部１００１にて電流値（Ｉｃ）を算出する（Ｓ１）。このとき、例えばゲート指令出力制御部１００２にて充電用コンデンサ１０５の充電が電圧値演算部１００３の演算値から十分であると判定したら、半導体遮断器１０２をオン状態にするゲート指令を出力する。このゲート指令の状態で、半導体遮断器へゲート指令出力しているかどうかをゲート指令出力制御部１００２にて判定する（Ｓ２）。半導体遮断器１０２のゲート指令が出力されていない場合、電源１００から充電抵抗１０１を介して、充電用コンデンサ１０５に電流が流れる。前記電流を所定値αとし、電流値比較部１００４にて電流値（Ｉｃ）と比較する（Ｓ３）。電流値（Ｉｃ）が所定値αより大きい場合、半導体遮断器１０２が短絡故障し大電流が流れたと判断できるため、半導体遮断器故障判定部１００５にて半導体遮断器１０２の短絡故障と判定する（Ｓ４）。 As shown in FIG. 2, a current value (Ic) is calculated by the current value calculation unit 1001 from the detection value of the current detector 104 (S1). At this time, for example, when the gate command output control unit 1002 determines that the charging of the charging capacitor 105 is sufficient from the calculated value of the voltage value calculating unit 1003, a gate command for turning on the semiconductor circuit breaker 102 is output. In this gate command state, the gate command output control unit 1002 determines whether or not a gate command is output to the semiconductor circuit breaker (S2). When the gate command of the semiconductor circuit breaker 102 is not output, a current flows from the power supply 100 to the charging capacitor 105 via the charging resistor 101. The current is set to a predetermined value α, and the current value comparison unit 1004 compares it with the current value (Ic) (S3). When the current value (Ic) is larger than the predetermined value α, it can be determined that the semiconductor breaker 102 has short-circuited and a large current has flown, so the semiconductor breaker failure determination unit 1005 determines that the semiconductor breaker 102 has a short-circuit failure ( S4).

このとき、電流値（Ｉｃ）が所定値αと同等の場合は、半導体遮断器故障判定部１００５にて半導体遮断器１０２が健全であると判定する（Ｓ５）。 At this time, if the current value (Ic) is equal to the predetermined value α, the semiconductor circuit breaker failure determination unit 1005 determines that the semiconductor circuit breaker 102 is healthy (S5).

半導体遮断器１０２のゲート指令が出力されている場合は、半導体遮断器用電圧検出器１０３の検出値より半導体遮断器１０２のコレクタ−エミッタ間電圧を検出する。前記電圧検出値より、電圧値演算部１００３にて電圧値を算出し、予め図３に示す半導体遮断器１０２が有する電圧―電流特性を保持している電流値比較部１００４は、電圧値演算部１００３に算出した電圧値を図３の特性図に用いることでコレクタ電流値を導出する。その後、導出したコレクタ電流値と電流値（Ｉｃ）を電流値比較部１００４にて比較する（Ｓ６）。電流値（Ｉｃ）が導出したコレクタ電流値と同等と電流値比較部１００４で判定された場合、半導体遮断器故障判定部１００５にて半導体遮断器１０２が健全であると判定する（Ｓ７）。 When the gate command of the semiconductor breaker 102 is output, the collector-emitter voltage of the semiconductor breaker 102 is detected from the detection value of the semiconductor breaker voltage detector 103. A voltage value calculation unit 1003 calculates a voltage value from the detected voltage value, and a current value comparison unit 1004 that holds in advance the voltage-current characteristics of the semiconductor circuit breaker 102 shown in FIG. The collector current value is derived by using the voltage value calculated in 1003 in the characteristic diagram of FIG. Thereafter, the derived collector current value and the current value (Ic) are compared by the current value comparison unit 1004 (S6). When the current value comparison unit 1004 determines that the current value (Ic) is equal to the derived collector current value, the semiconductor circuit breaker failure determination unit 1005 determines that the semiconductor circuit breaker 102 is healthy (S7).

このとき、電流値（Ｉｃ）が導出したコレクタ電流値と同等でないと電流値比較部１００４で判定された場合で、かつ、電流検出器１０４の検出値から電流値演算部１００１にて演算した電流値（Ｉｃ）と所定値αが同等であると（Ｓ８）、電源１００から充電抵抗１０１を介して、充電用コンデンサ１０５に電流が流れていることになり、半導体遮断器故障判定部１００５にて半導体遮断器１０２がオープン故障と判定する（Ｓ９）。 At this time, when the current value comparison unit 1004 determines that the current value (Ic) is not equal to the derived collector current value, and the current value calculated by the current value calculation unit 1001 from the detection value of the current detector 104 If the value (Ic) is equal to the predetermined value α (S8), current flows from the power source 100 to the charging capacitor 105 via the charging resistor 101, and the semiconductor breaker failure determination unit 1005 The semiconductor circuit breaker 102 is determined as an open failure (S9).

また、電流値（Ｉｃ）が所定値αと同等でない場合は、半導体遮断器１０２が短絡故障し大電流が流れたと判断できるため、半導体遮断器故障判定部１００５にて半導体遮断器１０２の短絡故障と判定する（Ｓ１０）。 Further, when the current value (Ic) is not equal to the predetermined value α, it can be determined that the semiconductor breaker 102 has a short circuit fault and a large current has flown. (S10).

本実施形態は、第１の実施形態とは半導体遮断器にチョッパ動作をさせるところ、および半導体遮断器の健全性を確認する方法が異なっている。以下、その点について詳細に説明する。 This embodiment is different from the first embodiment in that the semiconductor circuit breaker is chopper-operated and the method for confirming the soundness of the semiconductor circuit breaker. Hereinafter, this point will be described in detail.

3 shows a DC power supply 100, a semiconductor circuit breaker 102, a charging capacitor 105, a voltage detector 106, a power conversion circuit (or load) 107, a main ground 108, a second control unit 2000, a gate command control unit 2001, a voltage value. It is comprised by the calculating part 2002, the voltage state determination part 2003, and the semiconductor breaker failure determination part 2004. The power supply 100 and the semiconductor circuit breaker 102 are connected in series. The semiconductor breaker 102 and the positive side of the power conversion circuit (or load) 107 are connected. On the semiconductor circuit breaker 102 side, the power conversion circuit (or load) 107 and the charging capacitor 105 are connected in parallel. A voltage detector 106 is connected in parallel with the charging capacitor 105. A main ground 108 is connected between the power source 100 and the charging capacitor 105 on the negative side of the power conversion circuit (or load) 107. Further, the semiconductor circuit breaker 102 and the voltage detector 106 are connected to the control unit 1000.

また本実施形態は半導体遮断器１０２でチョッパ動作の制御を行うゲート指令制御部２００１、電圧検出器１０６と接続される電圧値演算部２００２、前記電圧値演算部２００２からの電圧演算値より電圧の状態を確認する電圧状態判定部２００３、電圧状態判定部２００３から半導体遮断器１０２の故障を判定する半導体遮断器故障判定部２００４で構成される第２制御部２０００を有している。 Further, in the present embodiment, a gate command control unit 2001 that controls chopper operation by the semiconductor circuit breaker 102, a voltage value calculation unit 2002 connected to the voltage detector 106, and a voltage calculation value from the voltage calculation value from the voltage value calculation unit 2002 are as follows. It has the 2nd control part 2000 comprised from the voltage state determination part 2003 which confirms a state, and the semiconductor circuit breaker failure determination part 2004 which determines the failure of the semiconductor circuit breaker 102 from the voltage state determination part 2003.

（作用）
本実施形態の作用について図３を参照して説明する。電源１００からの直流電力は、半導体遮断器１０２のチョッパ動作により、充電用コンデンサ１０５に供給される。充電用コンデンサ１０５の充電が完了すると、半導体遮断器１０２がチョッパ動作を止め、オン状態となる。また半導体遮断器１０２をオフすることで、回路を遮断することも可能である。 (Function)
The operation of this embodiment will be described with reference to FIG. DC power from the power supply 100 is supplied to the charging capacitor 105 by the chopper operation of the semiconductor circuit breaker 102. When the charging of the charging capacitor 105 is completed, the semiconductor circuit breaker 102 stops the chopper operation and is turned on. It is also possible to shut off the circuit by turning off the semiconductor circuit breaker 102.

図４に示すように、電圧値演算部２００２から充電用コンデンサ１０５に電力供給が必要な場合、ゲート指令制御部２００１にてゲート指令出力を制御することで、半導体遮断器１０２がチョッパ動作を開始し、充電用コンデンサ１０５に電力が供給され、充電用コンデンサ１０５の充電が開始される（Ｓ２００）。これにより、充電用コンデンサ１０５の電圧（Ｖｃ）を電圧検出器１０６出力より電圧値演算部２００２にて算出し、電圧値（Ｖｃ）が上昇しているかどうかを電圧状態判定部２００３で判定する（Ｓ２０１）。充電用コンデンサ１０５の電圧（Ｖｃ）が上昇していないと電圧状態判定部２００３にて判定された場合は、半導体遮断器故障判定部２００４にて半導体遮断器１０２の故障とする（Ｓ２０２）。 As shown in FIG. 4, when it is necessary to supply power from the voltage value calculation unit 2002 to the charging capacitor 105, the gate command control unit 2001 controls the gate command output so that the semiconductor circuit breaker 102 starts the chopper operation. Then, power is supplied to the charging capacitor 105, and charging of the charging capacitor 105 is started (S200). Thereby, the voltage (Vc) of the charging capacitor 105 is calculated by the voltage value calculation unit 2002 from the output of the voltage detector 106, and the voltage state determination unit 2003 determines whether or not the voltage value (Vc) is increasing ( S201). If the voltage state determination unit 2003 determines that the voltage (Vc) of the charging capacitor 105 has not increased, the semiconductor circuit breaker failure determination unit 2004 determines that the semiconductor circuit breaker 102 has failed (S202).

このとき、充電用コンデンサ１０５の電圧（Ｖｃ）が上昇していると電圧状態判定部２００３にて判定された場合は、充電用コンデンサ１０５の電圧（Ｖｃ）が既定時間内に既定の電圧値まで充電されているかどうかを電圧状態判定部２００３にて判定する（Ｓ２０３）。充電用コンデンサ１０５の電圧（Ｖｃ）が既定時間内に既定の電圧値まで充電されていると電圧状態判定部２００３にて判定された場合は、半導体遮断器故障判定部２００４にて半導体遮断器健全と判定する（Ｓ２０４）。また充電用コンデンサ１０５の電圧（Ｖｃ）が既定時間内に既定の電圧値まで充電されていないと電圧状態判定部２００３にて判定された場合は、半導体遮断器故障判定部２００４にて半導体遮断器故障と判定する（Ｓ２０５）。 At this time, when the voltage state determination unit 2003 determines that the voltage (Vc) of the charging capacitor 105 is increasing, the voltage (Vc) of the charging capacitor 105 reaches a predetermined voltage value within a predetermined time. Whether the battery is charged is determined by the voltage state determination unit 2003 (S203). When the voltage state determination unit 2003 determines that the voltage (Vc) of the charging capacitor 105 is charged to a predetermined voltage value within a predetermined time, the semiconductor circuit breaker failure determination unit 2004 determines that the semiconductor circuit breaker is healthy. (S204). When the voltage state determination unit 2003 determines that the voltage (Vc) of the charging capacitor 105 is not charged to a predetermined voltage value within a predetermined time, the semiconductor circuit breaker failure determination unit 2004 determines that the semiconductor circuit breaker is not charged. A failure is determined (S205).
