Abstract
(DE)
Um die in der IEC-Norm 60034 definierte Energieeffizienzklasse IE4 zu erreichen, ist es nötig, permanenterregte Synchronmaschinen direkt am Netz zu betreiben. Da dies nicht ohne weiteres möglich ist, kommen Sanftstarter als kosteneffiziente Lösung in Frage. Die vorliegende Anmeldung beschreibt ein Verfahren zur Drehzahlregelung einer permanenterregten Drehstrommaschine (M) mit einem Thyristoren umfassenden Sanftstarter (SS) mittels einer Reglerkaskade. Bei diesem werden alle möglichen Zündzeitpunkte der Thyristoren des Sanftstarters (SS) berechnet sowie ein zu jedem Zündzeitpunkt zugeordnetes Drehmoment bestimmt, das aus der Zündung der Thyristoren zu einem jeweiligen Zündzeitpunkt resultiert. Weiter wird ein Drehmomentkorridor (ΔMKorridor ) anhand einer vorgegebenen Berechnungsvorschrift, der die Ist-Drehzahl (nIst) und das Sollmoment als Eingangsgrößen zugeführt werden, bestimmt. Der Drehmomentkorridor wird zur Berechnung des Zündzeitpunkts verarbeitet. Es erfolgt dann die Bestimmung, welches der bestimmten Drehmomente in dem Drehmomentkorridor (ΔMKorridor) liegt und die Ermittlung des zugeordneten Zündzeitpunkts der Thyristoren. Anschließend erfolgt ein Zünden der Thyristoren zu dem zugeordneten Zündzeitpunkt.

In order to achieve the energy efficiency class IE4 defined in the IEC standard 60034, it is necessary to operate permanently excited synchronous machines directly from the power supply system. Since this is not readily possible, soft starters come into consideration as cost-effective solutions. The invention relates to a method for controlling the speed of a permanently excited three-phase machine (M) having a soft starter (SS) comprising thyristors by means of a controller cascade. In this method, all possible ignition timing points of the thyristors of the soft starter (SS) are calculated and also a torque is determined which is associated with each ignition timing point and which results from the ignition of the thyristors at a respective ignition timing point. Furthermore, a torque corridor (ΔMcorridor) is determined by means of a predetermined calculation rule, to which predetermined calculation the actual rotational speed (nIst) and the desired torque are supplied as input variables. The torque corridor is processed for computation of the ignition timing point. It is then determined which of the determined torques lies in the torque corridor (ΔMcorridor) and the associated ignition timing point of the thyristors is determined. Then, the thyristors are ignited at the associated ignition timing point.

Pour atteindre la catégorie de rendement énergétique IE4 définie dans la norme IEC 60034, il est nécessaire de faire fonctionner des machines synchrones à excitation permanente directement sur le réseau. Comme ce n’est tout simplement pas possible, des démarreurs progressifs constituent une solution économiquement rentable. La présente invention concerne un procédé permettant de régler la vitesse de rotation d’une machine à courant triphasé (M) à excitation permanente dotée d’un démarreur progressif (SS) correspondant des thyristors au moyen d’une cascade de régulateurs. Selon ce procédé, tous les points d’allumage possibles des thyristors du démarreur progressif (SS) sont calculés et un couple associé à chaque point d’allumage est déterminé, ledit couple résultant de l’allumage des thyristors à chacun des points d’allumage. En outre, une plage de couples (ΔMKorridor ) est déterminée sur la base d’une consigne de calcul prédéfinie, à laquelle sont acheminés la vitesse de rotation réelle (nIst) et le couple de consigne en tant que grandeurs d’entrée. La plage de couples est traitée pour calculer le point d'allumage. Il s’agit ensuite de déterminer, parmi les couples déterminés, celui qui se situe dans la plage de couples (ΔMKorridor) et d’obtenir le point d’allumage associé des thyristors. Pour finir, un allumage des thyristors intervient au point d’allumage associé.
