Definitions

• the invention relates to a method for operating an electrical rail vehicle connected to a DC network with a mains choke whose winding is connected with its input to the DC network and with their
• Output is connected to the traction converter of the rail vehicle.
• the invention has for its object to provide a method for operating an electrical rail vehicle connected to a DC network, with which the operation of such a rail vehicle can perform particularly energy and cost efficient.
• a significant advantage of the method according to the invention is seen in the fact that it allows an energy-efficient operation of a rail vehicle connected to a DC power supply, because the mains choke used is relatively light and therefore contributes to a reduction of the total weight of the rail vehicle.
• the line choke can be made comparatively small with regard to its iron core.
• the reduced iron cross-section also reduces the copper length. Due to this reduced copper length, the losses of the throttle are greatly reduced.
• the line reactor can be produced with relatively little effort.
• the respectively current compensation DC current can be formed in different ways. It may be advantageous if a current control differential value is used to set the respectively current compensation DC current, which is formed from a respectively current measured value of the compensation direct current and the respectively current measured value of the current at the output of the one winding of the mains choke. In this case, it is not necessary to carry out any measurements on the mains choke itself. On the other hand, it can also be advantageous to use the respectively measured value of the flux of the iron core for setting the respectively current compensation direct current and to set the compensation direct current in each case so that the measured value of the flux of the iron core becomes minimal. A measurement of the current at the output of a winding of the line reactor is then no longer necessary.
• the respectively measured value of the flux through the iron core is determined by means of a magnetic-field-sensitive sensor.
• the invention further relates to a connected to a DC power electrical rail vehicle with a mains choke whose winding is connected with its input to the DC power and is connected to its output to the traction converter of the rail vehicle.
• the mains choke is relatively heavy and bulky due to its necessarily large iron core. This also involves a relatively high operating energy requirement of the rail vehicle.
• the object of the invention is to further develop a rail vehicle of the type specified above in such a way that it has a relatively low weight and is energy-efficient and cost-effective to operate.
• the line choke at least one further winding, which is connected to the supply of a DC compensation current to an output of an active actuator, which is fed by a rail vehicle's own energy source.
• Such a rail vehicle has the same advantages analogously as they are listed above in connection with the method according to the invention.
• the formation of the compensation direct current is of particular importance.
• the active controller is connected to a power supply input to a bordnetzen power source of the electrical rail network and is applied to a control input with a control value, the represents a measure of the current current flooding of the iron core of the mains choke.
• an energy store is arranged for power storage between the on-board power source and the active controller. Due to the high capacitance values of double-layer capacitors, this can be advantageously constructed from such capacitors.
• a filter is arranged between the active positioner and the further winding of the line choke.
• the figure shows a DC network 1, which has a contact wire 2 and an earth conductor formed by a rail 3, with which a rail vehicle 4 is connected via a wheel 5.
• a voltage applied to the contact wire 2 pantograph 6 is followed by a main switch 7, to which a winding 8 of a line reactor 9 is connected to its input 10.
• One Output 11 of a winding 8 of the mains choke 9 is connected to an input 12 of a differential former 13.
• An output 14 of the difference former 13 is connected to a power supply line 16 via an arrangement 15 with a precharge circuit and a line contactor.
• the line choke 9 has a further winding 21, which is connected at one end 22 to an output 23 of a filter 24; the other end 25 of the further winding 21 is connected to a further input 26 of the difference former 13, which is connected to an additional input 27 to a further output 28 of the filter 24.
• the filter 24 receives via its inputs 29 and 30 output currents of an active actuator 31, which is shown here schematically in an embodiment as a four-quadrant controller.
• the four-quadrant controller 31 has a control arrangement 32, which is connected with its input 33 to a control output 34 of the difference former 13.
• the rail vehicle 4 contains a DC power source 35, which may be the vehicle electrical system of the rail vehicle 4.
• a capacitor arrangement 37 is connected to the DC power source 35, which is constructed from double-layer capacitors.
• Capacitor assembly 37 is connected via lines 36 and 37 with its power supply inputs 39 and 40 of the four-quadrant controller 31.
• the arrangement shown in the figure operates in the following manner: If the main switch 7 is actuated, then the one winding 8 of the mains choke 9 is acted upon by a direct current II. In order to reduce this direct current in its harmonics, this is passed through the line choke (9) to smooth this. This avoids a disruption of the rail network.
• the mains choke 9 is additionally provided with the further winding 21, which serves as a compensation winding 2 and receives a compensation direct current 12 from the four-quadrant controller 31 via the filter 24; this DC compensation current 12 corresponds (approximately) in terms of its size to the DC component in the current II from the DC network 1, taking into account the turns ratio.
• This is achieved by means of the subtractor 13 of the control arrangement 32 of the four-quadrant controller 31, a control value S is supplied, which leads to such a control of the four-quadrant controller 31 that this outputs a current 12 ', which leads to the compensation direct current 12 after filtering in the filter 24.
