Definitions
- the invention relates to a method for compensating the pendulum moments on an electric locomotive.
- Electric traction vehicles are usually driven by traction motors located on bogies or a carrier, which in turn are fed via converters. Because of the non-sinusoidal supply voltage of their converters, these traction motors generate high pendulum torques in addition to additional losses and radial force waves. The reaction forces of these pendulum torques often lead to deformations of the bogie or the support of the traction motors with sometimes considerable airborne noise emissions.
- valves of the machine power converters are controlled in such a way that each of the two intermediate circuit currents in the positive and negative direction is alternately switched for each sine half cycle via only two of the three phase connections by windings of the two stator winding systems, the electrical effect of which is orthogonal to one another.
- EPE ⁇ 99 Lausanne entitled “ASM double star system instability in de line ⁇ ” to use the double star motors, which are known per se, for the purpose of reducing network feedback.
- the object of the invention is to create a method for electric traction vehicles and a corresponding traction vehicle with which the air switching emissions, which can be considerable in some cases, are avoided during operation.
- the object is achieved by a method according to claim 1 and an electric traction vehicle according to claim 3 or 4.
- one component of the resulting pendulum torque can be reduced to zero.
- the partial winding systems are preferably formed from the odd-numbered 1,3, 5, .. and even-numbered coil groups 2,4,6, .. or from the coil groups 1 to n and n + 1 to 2n, where n are integers. Further combinations of subsystems are also conceivable.
- Another advantage of this invention is that the compensation of the disturbing pendulum torques already takes place in the air gap of the respective driving motor.
- This method can be used for all drive types, i.e. can be used with traction motors positioned crosswise or lengthways with respect to the direction of travel.
- Optimizing and adapting the pulse pattern is possible at any time, in particular through software exchange.
- other parasitic effects of the converter supply such as radial force waves and additional losses in the rotor, are sometimes considerably reduced depending on the operating mode.
- the axes of the subsystems are spatially offset by 180 ° / p and generate the air gap field which is normal per se in the respective traction motor when feeding in phase. This applies regardless of the winding design, i.e. for example of tendon, number of uses per pole and strand.
- Both partial winding systems of a traction motor are each fed from their own converter.
- Each converter preferably feeds the partial winding systems of several motors connected in parallel.
- the control of the at least two converters takes place via on / off signals with the same basic frequency and identical or different pulse patterns, whereby identical pulse patterns are to be used in those areas in which oscillation torque compensation is not required and different, specially optimized pulse patterns in those areas in which oscillation torque compensation takes place should. It is important that there is no phase shift of the fundamental oscillation with respect to one another when the partial winding systems are electrically supplied. Ideally, it is only those harmonics that lead to a pendulum moment in phase oppositions.
- the switching times are determined from the intersection points of a predetermined scanning curve, for example a triangular sawtooth curve, with a reference curve, for example a sine curve.
- a predetermined scanning curve for example a triangular sawtooth curve
- a reference curve for example a sine curve.
- the disturbing pendulum moment component is usually the one that is close to a mechanical natural frequency, e.g. of the bogie and without compensation would lead to noise emission and thus noise emissions from the locomotive. So it is e.g. It is conceivable to take stock of the frequency spectra when powered by the same pulse pattern when commissioning a locomotive, and to specify new pulse patterns optimized for eliminating the interfering frequencies in those areas where pendulum torque compensation is necessary or desirable.
- the two winding systems of the respective traction motor can be used for further optimizations, e.g. to reduce a radial force component or to reduce additional losses in the rotor windings.
- FIG. 2 shows a winding arrangement of a traction motor in a four-pole electrical machine.
- FIG. 1 shows a basic illustration of an electric locomotive, not shown in detail, with two bogies 1 and each with their traction motors Ml, M2 or M3, M4, which drive the associated wheel sets or individual wheels 2.
- Each traction motor M1-M4 has two partial winding systems. This
- Part winding systems M1T1-M4T2 form a double star in the stator connection in each traction motor Ml-M4.
- the partial winding systems M1T1-M4T2 of a traction motor M1-M4 are fed by different converters, in particular pulse-controlled inverters PWR1 and PWR2. It therefore feeds PWR1
- Part winding system M1T2, M2T2, M3T1 and M4T1 and the pulse inverter PWR2 feeds the part winding systems M1T1, M2T1, M3T2 and M4T2.
- FIG. 2 shows an embodiment for the winding arrangement of the stator of a four-pole drive motor with 24 slots.
- the 2xP 4 coil groups of one strand are shown.
- the coil groups SGI and SG3 form a partial winding.
- SG2 and SG4 the other partial winding of the strand.
- the series connection of the coil groups SG1, SG3 and SG2, SG4 is shown.
- a parallel connection of these coil groups SG1, SG2 and SG2, SG4 is also possible.
- the natural frequencies are recorded on the locomotives listed, for example, with their bogies 1. This advantageously already takes place during the commissioning phase, so that at this point in time the the required pulse pattern set is stored in the drive control unit. Instead of exchanging or reworking the bogies 1, it is only necessary to adapt the pulse pattern set in the control device 5. Vibration sensors or microphones on the bogie 1 can be used to detect the disturbing natural frequencies and to prove the improvements made.
- the method according to the invention for pendulum torque compensation can be used in particular in the locomotives described in FIG. 1. However, it is not absolutely necessary to use traction motors with double stars. More than two stars per drive motor Ml to M4 are also conceivable.
- This procedure can also be used for single-axle chassis or independent wheel suspensions.
