Description

Selbsttätige Regelung der Wirk- und Blindleistung einer Asynchronmaschine, die mit einem Einankerumformer und einer Gleichstrom-Hintermaschine in Kaskade geschaltet ist Die bekannte, aus Asynchronmaschine, Einankerumformer und Gleichstrom-Hintermaschine bestehende Kaskade kann sowohl dazu dienen, bei gegebener Netzfrequenz die Drehzahl der Asynchronmaschine als Motor zu regeln als auch bei gegebener veränderlicher Drehzahl die Frequenz der als Generator arbeitenden Asynchronmaschine nahezu konstant zu halten.Automatic regulation of the active and reactive power of an asynchronous machine, which are connected in cascade with a single armature converter and a DC rear machine is the well-known one, consisting of an asynchronous machine, a single armature converter and a DC rear machine The existing cascade can be used both to increase the speed at a given mains frequency to regulate the asynchronous machine as a motor as well as with a given variable Speed the frequency of the asynchronous machine working as a generator almost constant to keep.

DieAbbildung zeigt einen derartigen Regelsatz. v ist die Asynchronmaschine (Vordermaschine) mit veränderlicher Drehzahl. Sie beliefert ein Verbrauchernetz n, das außerdem noch von anderen Drehstromgeneratoren g gespeist wird. Zur Regelung dienen die Regler RIj und R", von denen ersterer auf die Erregung der Hintermaschineh, letzterer auf diejenige des Einankerumformers u einwirkt, und zwar beherrscht RI, im wesentlichen die Wirkleistung, R. die Blindleistung, welche ins Netz geliefert wird. RI, ist jedoch nicht ohne Einfuß auf die Blindleistung, und zwar um so mehr, je schwächer die Gleichstrom-Hintermaschine h erregt ist, da in diesem Bereich der Ohmsche Spannungsabfall zwischen v und dem Einankerumformer u eine große Rolle spielt. Häufig ist es erforderlich, die Wirk- und Blindleistung selbsttätig zu regeln, z. B. wenn die Asynchronmaschine von einem Windmotor angetrieben wird. Hierbei dient der Regler Rh zur Regelung der gelieferten Wirkleistung und der Regler R" zur Regelung der gelieferten Blindleistung. Dabei muß aber, wenn man Pendelerscheinungen vermeiden will, dafür gesorgt werden, daß beide Regelorgane sich nicht stören. Das geschieht erfindungsgemäß durch Ausbildung des einen Reglers als Schnellregler, des anderen als Langsamregler.The figure shows such a rule set. v is the asynchronous machine (Front machine) with variable speed. It supplies a consumer network n, which is also fed by other three-phase generators g. Regarding the regulation the controllers RIj and R "are used, the former acting on the excitation of the rear engine, the latter acts on that of the single armature converter u, and controls RI, essentially the active power, R. the reactive power, which is supplied to the network will. RI, however, is not without influence on the reactive power, and all the more so, the weaker the DC rear machine h is excited, since in this area the Ohmic voltage drop between v and the single armature converter u plays a major role. It is often necessary to regulate the active and reactive power automatically, e.g. B. when the asynchronous machine is driven by a wind motor. This serves the controller Rh for regulating the delivered active power and the controller R "for regulation the supplied reactive power. But if you have to avoid pendulum phenomena wants to be ensured that the two regulating organs do not interfere with each other. This happens according to the invention by designing one controller as a rapid controller, the other as a slow regulator.

Das Prinzip kann auch angewendet werden, wenn an Stelle der auf die Hauptrolle arbeitenden Gleichstrom-Hintermaschine h ein Gleichstrommotor tritt, der mit einem aufs Netz zurückarbeitenden Drehstromgenerator gekuppelt ist.The principle can also be applied if in place of the The main role of the working direct current rear machine h a direct current motor occurs, which is coupled to a three-phase generator that works back on the network.
