Definitions
- a rotary electric machine converts mechanical energy into rotational ⁇ current or three-phase current into mechanical energy. It can basically be operated as an electric generator or as an electric motor. As a soft start measures to limit the power when switching an electrical device, such as an electric motor called.
- Figure 1 shows a schematic representation of such a permanent-magnet synchronous machine, in the embodiment as internal nenpolmaschine with a stator St and a rotor L.
- the rotor comprises a magnetic north pole N and south pole S and winding strands U, V, W.
- the illustration is only by way of example and has no limiting effect on the scope of the claimed subject matter.
- a damper cage can be provided in the rotor of the machine, which although a safe run-up on the rigid network allows, however, the feeding mains heavily loaded by very high starting currents.
- the operation of a suitable shovektro ⁇ African actuator such as a frequency converter or soft start is possible.
- the A soft start is a cost-effective solution for starting up a permanent-magnet synchronous machine on a rigid network. At present, however, no marketable solution is known.
- the start method required differs from the prior art sensorless methods in that it is suitable for a thyristor controller rather than a frequency converter. Inverter must be usable. Thus, these known methods are not applicable.
- the problem of encoderless run-up can be divided into two sub-problems: Determination of the initial rotor angle, start-up of the machine (invention report is in progress).
- Figure 1 shows a section through an exemplary rotary ⁇ current machine
- Figure 2 is a diagram of the current direction with discrete
- FIG. 3 shows a simulated current profile in phase U
- FIG. 4 shows an exemplary profile of the electrical angle during the alignment process at different starting angles.
- the claimed process shows how the initial rotor Posi ⁇ tion can be set so that a run without encoder is possible.
- the electrical position of the machine is unknown and must be determined or determined.
- the machine is subjected to pulsating currents in a defined direction and aligned by them in the clear direction.
- the current profile is analyzed so that it can be determined whether the machine is actually moving. In the following, the individual steps are explained in more detail.
- quadrant I the phases V and W are ignited, in quadrant II the phases U and W, and in quadrant IV the phases U and V.
- two thyristors are fired only once at a very large ignition angle (eg 180 °) and the amplification of the phase currents ⁇ tudenwert determined. Due to the large ignition angle, the effective ⁇ on the machine voltage-time area and hence the maximum of the resulting current are very low. If the current amplitude is less than a defined maximum ⁇ worth the firing angle of the thyristor is slowly reduced by eg 180 ° and the current amplitude value again compared with the maximum value.
- a very large ignition angle eg 180 °
- This process is repeated until the amplitude value is sufficiently close to the maximum value.
- Phase U and V are ignited and the current in phase U is positive. So the angle in the vector is -30 °.
- the machine has already been able to align due to the pulsating currents. However, this does not guarantee that the machine is already fully aligned. For this reason, the thyristors are fired several times (the number is calibrated) with the determined optimum ignition angle, so that it can be assumed at the end that the machine is no longer moving and thus aligned. Finally, the course of the current space pointer is recorded during an ignition process and used as a reference curve in the subsequent measurements.
- the machine After the first alignment, it must be ensured that the machine can actually move freely and, secondly, that it can actually move in the direction of the flow and not exactly by 180 ° is aligned.
- the method described above is repeated with the same optimum ignition angle, but in a different current direction.
- phases U and V have been ignited
- phases V and W are now ignited.
- the procedure can be repeated or an error is reported to protect the machine from mechanical damage.
- FIGS. 3 and 4 show, by way of example, the simulated course of the phase current in phase U and the course of the electrical angle during the alignment process at different starting angles.
- the machine was simplified with a DC voltage applied, however, the basic statements are also valid for the excitation with a thyristor.
- two indicators of successful alignment can be introduced by calculating ⁇ s finish and comparison to a threshold ⁇ .
- the described starting method differs from the known encoderless methods in that it is suitable for a Thyristor and not a frequency converter must be usable. This has the direct result that a method with test SignalaufSchnaltung at low speeds due to the hardware topology is not feasible - the known methods are not transferable to the present application.
