- FIG. 1 shows a block diagram of a voltage generating device 10 with a diesel engine 1, which is functionally coupled to a third-party excited generator device (alternator) 2.
- a rotational speed n d of the externally excited generator device 10 is thereby provided by the diesel engine 1, where ⁇ for supplying a defined rotational speed n d, for example, a diesel injection quantity of the diesel engine 1 is dosed ⁇ accordingly.
- the generating means 2 is externally excited by an excitation device 3, thereby realizing a separately excited Syn ⁇ chronmaschine.
- an electrical voltage ei ⁇ ner vehicle electrical system battery is supplied via a controller to the generator 2, wherein an electrical voltage is formed in dependence on the generated three-phase voltage ⁇ .
- the three-phase electrical output voltage of the generator ⁇ gate device 2 is supplied to a rectifier device 20 in the form of a passive diode rectifier.
- At the output of the rectifier device 20 is in a DC link 30 with a DC link capacitor rectified electrical output voltage u ZK (Zwischennikspan ⁇ tion) available, to which an electrical load, in shape at least one power converter of an electrical consumption ⁇ device 40 is connected.
- Power converters of the electrical consuming device 40 can be designed as a traction converter, auxiliary converter, traction power supply, etc., by means of the auxiliary mode converter electrical auxiliary equipment of the ⁇ selelektrischen vehicle, such as air conditioning, heating, control of brakes, etc., electrically powered become.

- the generator devices 2 driven by the diesel engines are usually electrically foreign-excited.
- an electrical intermediate circuit voltage u ZK results proportional to the speed of the diesel engine 1. This characteristic fits well with the requirements of the traction motors of the diesel-electric vehicle.
- the excitation device 3 takes over a fine adjustment and a load ⁇ compensation of the alternator. 2
- the power also increases with the speed of the diesel engine 1, but a case may occur that, although a high DC link voltage is required, but not a high electric power, e.g. at standstill of the electric vehicle.
- this due to the formula (1), conventionally, this always requires a high rotational speed of the diesel engine 1 with the corresponding adverse effects concerning primary energy consumption and emissions of the diesel engine 1.
- Converters and transformers must be designed for operation at lower electric intermediate circuit voltage U ZK high elekt ⁇ generic streams, and for operation at high electric intermediate circuit voltage U ZK for the high electrical ⁇ intermediate circuit voltage U ZK.
- the internal auxiliary operations of the diesel electric ⁇ ⁇ rischen vehicle receive its own small inverter and the Glasenergiemakers with their higher performance is designed only for a limited electrical voltage range.
- this has the disadvantage of the consequence that the diesel engine 1 must always work with increased supply power with increased or high speed.
- the generator device 2 shows such a conventional arrangement, in which case the generator device 2 is designed as an asynchronous machine or a machine permanently excited by means of a permanent magnet.
- the generator device 2 in order to realize the desired output voltage, a missing magnetization must be adjusted by a reactive current on the power side, whereby the reactive electrical current is provided by means of the pulse rectifier 21.
- the generator device 2 can be magnetized or demagnetized.
- a pulse rectifier 21 can be used with heavily designed diodes and weaker dimensioned electronic switching elements (eg transistors). In this way the functiona ⁇ formality of the passive rectifier 20 and the pulse rectifier ⁇ ters can be implemented in a single module 21, in which case the diodes of the pulse rectifier 21 also assume the function of the passive rectifier 20th
- P represents here a generatable by means of the ⁇ selmotors 1 and the generating means 2 elekt ⁇ generic performance. If the required power exceeds PI, then the power flow at no longer pulsating pulse rectifier 21 as in the conventional solution according to FIG 1 is exclusively on the passive rectifier 20 in the form of diode bridges.
- the power PI is advantageously chosen such that the natural characteristic curve of the generator device 2 at PI just delivers the minimum electrical intermediate circuit voltage u ZK min. At full load while the high efficiency of the passive rectifier 20 is advantageously used.
- the pulse rectifier 21 is dimensioned, for example, at a selected ⁇ ZK min of 0.77 to approximately half the power of the electric power generated by the diesel engine 1 and the generator device 2.
- the inventive solution according to FIG 3 allows to use approximately all the advantages of a solution with a generating means 2 in the form of an asynchronous / permanent-magnet synchronous machine and exclusively present pulse rectifier 21 at ver ⁇ ringertem effort.
- the electrical intermediate circuit voltage u ZK can thereby be raised in the small power range, which advantageously makes possible an economical design for the auxiliary converter.
- a desired value u ZK min of the electrical intermediate circuit voltage is supplied to the pulse equalizer 21 and a desired value of the electric power Psoii the voltage generating device 10. In this way, advantageously decoupling the An ⁇ requirements on the parameters DC link voltage and power to a speed of the diesel engine 1 can be achieved , Provision of electrical power of the intermediate circuit continues to take place exclusively via the rotational speed of the diesel engine 1.
- the diesel engine 1 can be operated at an optimum operating point, because it is above all ready for use.
- Position of an electrical power is operated, wherein a request for a level of the electrical DC link voltage is met by the pulse rectifier 21.
- the pulse rectifier 21 can be dimensioned significantly smaller than the conventional solution according to FIG.
- the electrical short-circuit currents flow the rotary current generator 2 via the robust rectifier bridge of the passive rectifier 20 and do not affect dimensioning ⁇ rend to the pulse rectifier 21 out.
- a starting of the diesel engine 1 can be done from the intermediate circuit 30 by reversing the flow of energy through the pulse rectifier 21 and the alternator 2, so that in this way the alternator 2 can act advantageously as a starter for the diesel engine 1.
- the pulse rectifier 21 except in the case of a short circuit, if no isolator for the pulse rectifier ⁇ 21 is provided, an emergency operation is possible.
- only the rotational speed of the diesel engine 1 must always be kept greater than the rotational speed n m belonging to the natural electrical intermediate circuit voltage u ZK min of the alternator 2.
- the electric intermediate circuit chip ⁇ voltage U ZK min represents one target value of a consumer ⁇ chers the electrical consumers direction 40. in several consumers within the electrical consumption device 40 with different requirements for the electric intermediate circuit voltage represents u ZK min the highest Shaped ⁇ derten value of Electrical DC link voltage.
- the solid curve shows a typical course of an electrical intermediate circuit voltage u ZK as a function of the rotational speed, which lies in a range of approximately 1: 3.
- the diesel engine 1 must be operated at a relatively high speed in order to provide the required DC link voltage U ZK .
- An increase of the electrical intermediate circuit voltage at low speeds of the diesel engine 1 thus relieves the Zwi ⁇ circuit 30 is electrically powered converter and makes it technically less expensive and thus more cost-effective.
- this point can be defined defined, so that a generation of the DC link voltage 30 defined between the pulse rectifier 21 and the passive rectifier 20 can be divided.
- the supply of the electrical intermediate circuit voltage u ZK again takes over exclusively the three-phase generator 2 driven by the diesel engine 1, the voltage of which is rectified by the passive rectifier 20.
- the double arrow in FIG 4 thus represents a proportion of Zvi ⁇ link voltage, the advantageous from the pulse rectifier 21 is generated independently of the speed of the diesel engine 1.
- the pulse rectifier 21 From the rotational speed of the diesel engine 1 at the point K, the pulse rectifier 21 is inactive, the electric DC link voltage being provided exclusively from the rotational speed of the diesel engine 1 with the rectification functionality of the passive diode rectifier 20 from this point in time. From FIG 4 it can be seen that due to the dependence of the power of the speed to the third power of the pulse rectifier 21 can be dimensioned much smaller than that of FIG 2. In the case of FIG 4, where point K is about 0.77 of the rated speed of the diesel engine 1, the power of the pulse rectifier 21 can be designed to be 0.77 3 , ie about 45% of the power of the diesel engine 1.
- the pulse rectifier 21 In the event that the target value u ZK min of the electrical allespispan ⁇ tion is at half the diesel engine speed, the pulse rectifier 21 must be designed only to 12% of the power of the diesel engine 1.
- the double arrow of FIG 4 repre ⁇ advantage thus indirectly a power aspect for Di ⁇ dimensioning of the pulse rectifier 21st
- FIG 4 is made thus clear that a dimensioning of the pulse rectifier 21 can be significantly smaller than the nominal power of the diesel engine 1, wherein an actual Dimension ⁇ dimensioning the requirement of minimum electric intermediate circuit voltage depends. With FIG 4 should therefore be shown above all a degree of freedom obtained for the provision of the electrical intermediate circuit voltage.
- FIG. 5 shows a basic flow diagram of an embodiment of the method according to the invention for operating an electric power generation system.
- a step 100 supplying an electric DC link voltage U ZK min required by the consuming device 40 to the pulse rectifier 21 is performed.
- a step 110 an operation of the pulse rectifier 21 is performed such that the required electrical intermediate circuit voltage u ZK min is provided independently of a rotational speed of the diesel engine 1 by means of a raising function of the pulse ⁇ rectifier 21.
