Description

In vielen Fällen werden Wechselstrommaschinen im Stillstand unmittelbar an das Netz angeschlossen, so daß sie asynchron anlaufen. Ein derartiges Anlassen hat jedoch «ine verhältnismäßig große Blindstrombelastung in dem Netz zur Folge, so daß dieses bisher nur bei verhältnismäßig kleinen Maschinenleistungen angewendet werden konnte. Um diese Blindstrombelastung zu beherrsehen, hat man parallel zu den Maschinen Kondensatoren eingeschaltet. Dies bedeutet jedoch eine wesentliche Verteuerung der Anlage und bringt außerdem noch die Gefahr mit sich, daß bei dem Einschalten der Kondensatoren gleichfalls ein unzulässiger Blindstromstoß eintritt.In many cases, AC machines are directly connected to the Network connected so that they start asynchronously. However, such annealing has «A relatively large reactive current load in the network, so that this so far could only be used with relatively small machine outputs. In order to control this reactive current load, one has to work in parallel with the machines Capacitors turned on. However, this means a significant increase in the cost of the system and also brings with it the risk that when the capacitors are switched on an impermissible reactive current surge also occurs.

Nach der Erfindung können die genannten Nachteile beim asynchronen Anlassen von mit Käfigwicklung ausgerüsteten Synchronmaschinen einer Anlage weitgehend dadurch vermieden werden, daß die zuerst angelassene Maschine vor dem Zuschalten der nächstfolgenden derart übererregt wird, daß sie die Blindkomponente des Anlaufstromstoßes übernimmt. Auf diese Weise ist ein gefährlicher Blindstromstoß vermieden, zumal auch die Einstellung der Erregung der Maschine nicht stoßweise erfolgt, und zwar ohne daß irgendeine besondere Einrichtung, die immer eine Verteuerung der Anlage mit sich bringen würde, notwendig wird.According to the invention, the disadvantages mentioned when starting with asynchronous Cage winding equipped synchronous machines of a system are largely avoided in that the first started Machine is so overexcited before switching on the next following that it the Reactive component of the starting current surge takes over. Doing this is a dangerous one Reactive current surge avoided, especially since the setting of the excitation of the machine is not occurs intermittently, without any special facility, which is always a Would increase the cost of the plant, becomes necessary.
