Be provided with electric quantity detection apparatus 22a, 22b, the 22c that detects load bus 14 electric weight at each auxiliary power unit (APU) 13a, 13b, 13c.Required electric weight when electric weight is parallel synchronous operation is to judge for example electric current etc. of the required electric weight of voltage, the phase place of load bus 14.
The electric quantity detection apparatus 22b of auxiliary power unit (APU) 13b detects the electric weight of load bus 14a of the front of adjacency, and the electric quantity detection apparatus 22c of auxiliary power unit (APU) 13c similarly detects the electric weight of load bus 14b of the front of adjacency.In addition, though the auxiliary power unit (APU) 13a of the vehicle of front is provided with electric quantity detection apparatus 22a, because front does not have load bus 14, institute thinks disconnected.
Under the off-state of bus contactless switch 19a, 19b, auxiliary power unit (APU) 13a, 13b, 13c are according to connect load contactless switch 15a, 15b, 15c from exterior enabled instruction.And the voltage of auxiliary power unit (APU) 13a, 13b, 13c self rises.Auxiliary power unit (APU) 13a establishes the voltage of the load bus 14a of self thus.Auxiliary power unit (APU) 13b, 13c carry out parallel synchronous operation and prepare, determine with the auxiliary power unit (APU) 13a of adjacency, when 13b parallel synchronous operation condition is set up when the electric weight that detects based on electric quantity detection apparatus 22b, 22c simultaneously, connect bus contactless switch 19a, 19b and make the phase mutually synchronization.
Fig. 2 is the instruction diagram according to the startup sequence of operation of the supply unit of the railway vehicle of first embodiment of the invention.Make bus contactless switch 19a, the 19b of load bus 14 be in off-state.That is to say that making each load bus 14a, 14b, 14c is state of insulation.Under this state, each auxiliary power unit (APU) 13a, 13b, 13c export simultaneously from exterior actuation signal.
Each auxiliary power unit (APU) 13a, 13b, 13c rise output voltage by single operation (asynchronous operation) and move.The closed load contactless switch 15a (S1) of the auxiliary power unit (APU) 13a of front end, and output voltage is risen in modes such as soft starts, thus power to load bus 14a.
Auxiliary power unit (APU) 13b rises output voltage with single operation (asynchronous operation) and moves, and closed load contactless switch 15b (S2) behind the establishment voltage powers to load bus 14b with the output voltage of establishing.And, auxiliary power unit (APU) 13b detects output voltage and the phase condition of auxiliary power unit (APU) 13a from load bus 14a, and carries out voltage and phase place are transferred to and can be prepared (S3) with the such synchronized operation of the state of auxiliary power unit (APU) 13a parallel synchronous operation.When finishing synchronized operation and preparing (S4), the closed bus contactless switch 19a (S5) that load bus 14a and load bus 14b are linked together, auxiliary power unit (APU) 13a and auxiliary power unit (APU) 13b enter parallel synchronous operation.
Similarly, auxiliary power unit (APU) 13c rises output voltage by single operation (asynchronous operation) and moves, and closed load contactless switch 15c (S6) behind the establishment voltage powers to load bus 14c with the output voltage of establishing.And, auxiliary power unit (APU) 13c detects output voltage and the phase condition of auxiliary power unit (APU) 13b from load bus 14b, and carries out voltage and phase place are transferred to and can be prepared (S7) with the such synchronized operation of the state of auxiliary power unit (APU) 13b parallel synchronous operation.When finishing synchronized operation and preparing (S8), the closed bus contactless switch 19b (S9) that load bus 14b and load bus 14c are linked together, auxiliary power unit (APU) 13b and auxiliary power unit (APU) 13c enter parallel synchronous operation.
Like this, connect behind all bus contactless switch 19a, 19b and become parallel synchronous operation, finish the startup of parallel synchronous operation as all auxiliary power unit (APU) 13a, 13b, the 13c of marshalling.
In the above description, make synchronized operation, also can detect successively with the back electric weight of the load bus 14 of tail side adjacency and make synchronized operation though electric quantity detection apparatus 22 detects the electric weight of load bus 14 with the front adjacency of marshalling vehicle successively.
In addition, though closed load contactless switch 15a after the auxiliary power unit (APU) 13a of front end input enabled instruction, and thereby output voltage is risen to load bus 14a power supply, but also can determine that the output back connects load contactless switch 14a and power to load bus in modes such as soft starts.On the contrary, though auxiliary power unit (APU) 13b, 13c rise output voltage and move, closed load contactless switch 15b, 15c behind the establishment voltage, but also can be after the input enabled instruction closed load contactless switch 15b, 15c, output voltage risen and power in modes such as soft starts to load bus 14b, 14c.
Moreover, auxiliary power unit (APU) 13 self load bus 14 or the load bus 14 of adjacency under the situation of et out of order, can disconnect bus contactless switch 19a, 19b, disconnection load bus 14 in bad order.For example, under the load bus 14c situation in bad order, disconnect bus interceptor 19b.
Therefore, draw the load bus 14 of logical marshalling vehicle on each auxiliary power unit (APU) 13, to insulate, take place to have and other load bus 14 open circuited open functions under the situation of faults such as ground faults at load bus 14 by bus contactless switch 19.
In addition, load bus 14 is cut apart by bus contactless switch 19, and its auxiliary power unit (APU) 13 detects by this load bus 14 and the output voltage of the auxiliary power unit (APU) 13 of front (the perhaps back tail side) adjacency of marshalling vehicle, detect output according to this again and establish initial parallel synchronous operation preparation and connect bus contactless switch 19, carry out parallel synchronous operation.
According to first embodiment, because the prepare control of parallel synchronous operation is to be undertaken by the electric weight (voltage, phase place) that detects the auxiliary power unit (APU) 13 of vehicle front or back tail side via load bus, so do not need to be used for the dummy bus that parallel synchronous operation is prepared.
Below, the second embodiment of the present invention will be described.Fig. 3 is the constructional drawing according to the supply unit of the railway vehicle of second embodiment of the invention.This second embodiment replaces the parallel synchronous operation of auxiliary power unit (APU) 13 of a marshalling, is applicable to the parallel synchronous operation when marshalling carried out shuffling each other.Below, consider that the train to the train of A marshalling and B marshalling carries out the situation of shuffling.Auxiliary power unit (APU) 13A at the supply unit of A marshalling carries out parallel synchronous operation, and the supply unit of B marshalling carries out under the situation of single operation, A marshalling and B are organized into groups when carrying out shuffling, the auxiliary power unit (APU) 13Ba of the front end of B marshalling detects the electric weight of the load bus 14A of A marshalling by electric quantity detection apparatus 22Ba, after finishing the synchronized operation preparation, closed bus contactless switch 19B, parallel synchronous operation auxiliary power unit (APU) 13A and the auxiliary power unit (APU) 13Ba that load bus 14A and load bus 14Ba are linked together.
Similarly, auxiliary power unit (APU) 13Bb detects the electric weight of the load bus 14Ba of A marshalling by electric quantity detection apparatus 22Bb, finishing synchronized operation prepares, the closed bus contactless switch 19Ba that load bus 14Ba and load bus 14Bb are linked together makes auxiliary power unit (APU) 13Ba and auxiliary power unit (APU) 13Bb parallel synchronous operation.
Fig. 4 is the instruction diagram according to the startup sequence of operation of the supply unit of the railway vehicle of second embodiment of the invention.The supply unit that figure 4 illustrates the supply unit of A marshalling and B marshalling carries out the situation of shuffling when carrying out parallel synchronous operation.Auxiliary power unit (APU) 13Bb detects output voltage and the phase condition of auxiliary power unit (APU) 13A from load bus 14A, and carries out voltage and phase place are transferred to and can be prepared (S11) with the such synchronized operation of the state of auxiliary power unit (APU) 13A parallel synchronous operation.After finishing synchronized operation and preparing (S12), the closed bus contactless switch 19B (S13) that load bus 14A and load bus 14Ba are linked together, parallel synchronous operation auxiliary power unit (APU) 13A and auxiliary power unit (APU) 13Ba then.
Even to the marshalling of parallel synchronous operation each other shuffling or the marshalling of single operation also all become identical action with the marshalling shuffling each other of parallel synchronous operation.That is to say that when shuffling, a side auxiliary power unit (APU) 13 detects voltage and phase information from the opposing party's load bus 14, after the preparation of parallel synchronous operation finishes, connect bus contactless switch 19 and realize by the parallel synchronous operation of the marshalling of shuffling.
According to second embodiment, even when marshalling is carried out shuffling each other, even if marshalling is asynchronous operation each other before the shuffling, but pass through behind the shuffling through the such action of synchronized operation readiness for closing bus contactless switch, the parallel synchronous operation that comprises the shuffling vehicle also is easy to realize.
