Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Reduzierung von Oberwellen und interharmonischer Wellen für Leistungssteuerungen von an einem Wechselspannungsnetz angeschlossenen elektrischen Verbrauchern.The The invention relates to a method and a device for reducing Harmonics and interharmonic waves for power control of connected to an AC mains electrical consumers.
Leistungssteuerungen von elektrischen Verbrauchern, die an einer Wechselspannung, üblicherweise der Netzspannung, angeschlossenen sind, sind zumeist als Phasenanschnittsteuerung realisiert, bei der der Stromfluss nach dem Nulldurchgang der Wechselspannung bis zu einem einstellbaren Zündwinkel verzögert wird, ab dem der Verbraucher bis zum nächsten Nulldurchgang des Stromes mit Energie versorgt wird, wodurch die über eine Periode der Wechselspannung gemittelte Leistung eingestellt werden kann. Der größte Nachteil von Phasenanschnittsteuerungen ist der nicht-sinusförmige Verlauf des Stromes, der im Netz Störungen hervorruft. Da Strom und Spannung nicht dieselbe Form besitzen, ergibt sich eine Blindleistung, die in der Darstellung als Spektrum Oberschwingungen besitzt und elektronische Geräte beschädigen kann.power controllers of electrical loads connected to an AC voltage, usually The mains voltage, are connected, are mostly as a phase control realized at the current flow after the zero crossing of the AC voltage up to an adjustable ignition angle delayed from, the consumer until the next zero crossing of the current is energized, causing over a period of AC voltage average power can be adjusted. The main drawback of phase control is the non-sinusoidal course of the current, the network disturbances causes. Since current and voltage do not have the same shape, results itself a reactive power, which in the representation as spectrum harmonics owns and electronic devices to damage can.
Es
sind diverse Modulationsverfahren zur Reduzierung der Oberwellen
bekannt:
Dieses Verfahren reduziert zwar die Oberwellen der anliegenden Wechselspannung, erzeugt aber zusätzlich Wellen mit den Vielfachen der halben Frequenz der anliegenden Wechselspannung, den so genannten Interharmonischen.This Although the method reduces the harmonics of the applied AC voltage, but generates additionally Waves with multiples of half the frequency of the applied AC voltage, the so-called interharmonics.
Dieses Verfahren benötigt aber eine Vorrichtung, die neben den Elementen einer Phasenanschnittsteuerung ein zusätzliches Schaltelement und ein stromlimitierendes Element erfordert.This Procedure needed but a device that beside the elements of a phase control an additional Switching element and a current-limiting element requires.
Der Erfindung liegt die Aufgabe zugrunde, für Leistungssteuerungen von an ein Wechselspannungsnetz angeschlossenen elektrischen Verbrauchern die parasitär erzeugten Oberwellen und interharmonischer Wellen zu reduzieren und die dafür benötigte Vorrichtung einfach und kostengünstig zu halten.Of the Invention is based on the object for power control of connected to an AC mains electrical consumers the parasitic to reduce generated harmonics and interharmonic waves and the one for that needed Device simple and inexpensive to keep.
Erfindungsgemäß wird diese Aufgabe durch ein Verfahren mit den Merkmalen des 1. Patentanspruchs gelöst, indem der Zündwinkel je Halbwelle der speisenden Wechselspannung in einer wiederkehrenden Sequenz derart gewählt wird, dass zum einen die Leistung annähernd sinusförmig variiert, ohne dass das Gleichgewicht der Leistung zwischen positiven und negativen Halbwellen im Mittel aufgehoben wird, zum anderen die über die Sequenz gemittelte Leistung eingestellt werden kann.According to the invention this Task by a method having the features of the first claim solved, by the ignition angle each half-wave of the supplying alternating voltage in a recurring Sequence selected in such a way is that on the one hand the power varies approximately sinusoidally, without that the balance of power between positive and negative Half waves on average is lifted, on the other hand, over the Sequence averaged power can be adjusted.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass sich Phase und Amplitude der durch das Schalten der Wechselspannung erzeugten Oberwellen aufgrund der beschriebenen Auswahl des Zündwinkels derart gestalten, dass sie sich im Mittel auslöschen können. Das durch die Variation des Zündwinkels erzeugte Brummen verfügt nur über wenige Oberwellen und die Frequenz kann durch Verändern der Sequenzlänge in Grenzen an die Applikation angepasst werden.The particular advantages of the invention are that is the phase and amplitude of the switching of the AC voltage generated harmonics due to the described selection of the ignition angle in such a way that they can wipe out on average. That through the variation the ignition angle generated hum only over few harmonics and the frequency can be changed by changing the sequence length be adapted within limits to the application.
