Abstract
Description
Die vorliegende Erfindung betrifft eine Schaltung zur Regelung der Wechselspannung in einem Wechselspannungsnetz. Das besagte Netz kann ein Versorgungsnetz und/oder Verbraucheranlage sein. Insbesondere können damit die einzelnen Phasen eines Niederspannungs-Ortsnetzes voneinander unabhängig geregelt werden.The present invention relates to a circuit for controlling the AC voltage in an AC voltage network. Said network may be a utility grid and / or consumer facility. In particular, the individual phases of a low-voltage local network can thus be regulated independently of one another.
Im Falle der Verbraucheranlage wird die vom Versorgungsnetz zur Verfügung gestellte Wechselspannung innerhalb eines engeren Toleranzbandes gehalten als vom Versorgungsnetz vorgegeben.In the case of the consumer system, the AC voltage provided by the supply network is kept within a narrower tolerance band than specified by the supply network.
Im Falle des Versorgungsnetzes wird die Wechselspannung zu den Verbraucheranlagen hin in einem definierten Toleranzband gehalten. Dies ist insbesondere in Hinblick auf die zukünftig vermehrt auf Ortsnetzebene eingespeisten Spannungen aus regenerativen Energien notwendig.In the case of the supply network, the AC voltage is kept to the consumer equipment out in a defined tolerance band. This is particularly necessary in view of the future increasingly fed on local level voltages from renewable energy.
Bisher ist der Verteiltransformator für das Ortsnetz auf ein festes Übersetzungsverhältnis eingestellt, da das Ortsnetz eine relativ konstante Last darstellt. Die nun von der Tageszeit und Wetterbedingungen abhängige stark schwankende Rückspeisung bzw. Einspeisung bedingt eine ständige Anpassung an die aktuellen Last- und Speisebedingungen.So far, the distribution transformer for the local network is set to a fixed gear ratio, since the local network is a relatively constant load. The heavily fluctuating feedback or feed, which is now dependent on the time of day and weather conditions, requires constant adaptation to the current load and feed conditions.

Die in dem Prospekt „Netzregler” der Fa. Walcher GmbH & Co. KG beschriebene Anlage benötigt mehrere hintereinander geschaltete Transformatoren als Regeltransformator zur Abdeckung des Regelbereiches. Die Primärseiten der einzelnen Transformatoren werden bei Bedarf mit der zu regelnden Spannung durch Schütze verbunden. An den verwendeten mechanischen Schaltgliedern ist ein geringerer Spannungsabfall als an Thyristoren oder IGBTs zu erwarten und damit auch eine geringere Verlustleistung. Jedoch überwiegen die bereits vorgenannten, beschriebenen Nachteile hinsichtlich Verluste. Darüber hinaus ist durch die Verwendung von mechanischen Elementen eine geringe Lebensdauer zu erwarten.The system described in the brochure "Netzregler" from Walcher GmbH & Co. KG requires several series-connected transformers as a regulating transformer to cover the control range. If required, the primary sides of the individual transformers are connected to the voltage to be regulated by contactors. At the mechanical switching elements used, a lower voltage drop is expected than at thyristors or IGBTs and thus also a lower power loss. However, the above-mentioned, described disadvantages in terms of losses prevail. In addition, the use of mechanical elements is expected to have a short lifetime.
In der Veröffentlichung „Transformatorische AC Spannungskonstanthalter” der Ruhstrat GmbH vom April 2002 ist die Ausführung einer Anlage beschrieben, die dem Verfahren gemäß der
Aufgabe der vorliegenden Erfindung ist es, eine Schaltung und Verfahren zu schaffen, welche die Regelung einer Wechselspannung ermöglicht und dabei einen verringerten Leistungsverlust aus bekannte Systeme aufweist.The object of the present invention is to provide a circuit and method which enables the regulation of an AC voltage and thereby has a reduced power loss from known systems.
Diese Aufgabe wird mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1 gelöst. Fortbildungen und vorteilhafte Ausführungen der Erfindung sind in den weiteren Ansprüchen umfasst.This object is achieved with the features of the characterizing part of
Erfindungsgemäß ist eine Einrichtung zur Regelung und/oder Steuerung von Wechselspannung, insbesondere für oder in Wechselstromnetzen und Wechselstrom-Versorgungsnetzen, wobei ein Steuertransformator parallel zu der zu regelnden und/oder zu steuernden Wechselspannung mit mindestens einer Sekundärwicklung mindestens eine Steuerspannung für die Primärseite mindestens eines Regeltransformators, dessen Sekundärseite in Reihe mit der zu regelnden Spannung liegt, bereitstellt und die Anschlüsse der mindestens einen Sekundärseite des Steuerungstransformators mit den Anschüssen der Primärseite mindestens eines Regeltransformators mittels Schaltglieder verbindbar sind.According to the invention, a device for regulating and / or controlling AC voltage, in particular for or in AC networks and AC supply networks, wherein a control transformer in parallel with the regulated and / or controlled AC voltage with at least one secondary winding at least one control voltage for the primary side of at least one control transformer , whose secondary side is in series with the voltage to be regulated, provides and the terminals of the at least one secondary side of the control transformer with the terminals of the primary side of at least one control transformer can be connected by means of switching elements.
Der Steuertransformator, dessen mindestens eine Primärseite parallel zur Wechselspannung angeordnet ist versorgt aus seiner mindestens einen Sekundärseite mindestens einen Regeltransformator, welcher mit seiner Sekundärseite in Reihe in der zu regelnden Wechselspannung angeordnet ist. Die Anschlüsse der mindestens einen Sekundärseite des mindestens einen Steuertransformators sind mittels Schaltgliedern, welche bevorzugt als Halbleiterschalter ausgeführt sind, mit der Primärseite mindestens eines Regeltransformators verbunden. Es werden dabei bevorzugt so viele Schaltglieder eingesetzt, dass gleich- und gegenläufige Anschlussvarianten erzeigt werden können und die indizierte Spannung an der Sekundärseite des Regeltransformators die endgültige Versorgungs- oder Abgriffspannung entsprechend erhöht oder verringert. Der Steuertransformator hat dabei bevorzugt ein Übersetzungsverhältnis welches größer als 100% ist.The control transformer whose at least one primary side is arranged parallel to the AC voltage supplies from its at least one secondary side at least one control transformer, which is arranged with its secondary side in series in the AC voltage to be regulated. The connections of the at least one secondary side of the at least one control transformer are connected to the primary side of at least one regulating transformer by means of switching elements, which are preferably designed as semiconductor switches. It is preferred that so many switching elements are used that the same and opposite connection variants can be shown and the indicated voltage on the secondary side of the control transformer increases or decreases the final supply or tap voltage accordingly. The control transformer preferably has a transmission ratio which is greater than 100%.
Durch die Verwendung unterschiedlicher Ausführungsformen des Steuertransformators, wie beispielsweise mit mehreren Abgriffen auf der Sekundärseite oder in Ausführung als Spartransformator können unterschiedliche Steuerspannungen und Bedingungen geschaffen werden. So stehen beispielsweise durch die Ausführung des Steuertransformators mit mehreren Sekundärwicklungen oder Abgriffen eine Mehrzahl von Spannungen zur Verfügung welche für die Versorgung des Regeltransformators verwendet werden können. Durch die unterschiedliche und sich über einen größeren Bereich erstreckende Spanungsversorgung des Regeltransformators ergibt sich ein entsprechend großer Regelbereich für die zu regelnde Wechselspannung.By using different embodiments of the control transformer, such as with multiple taps on the secondary side or in execution as autotransformer different control voltages and conditions can be created. Thus, for example, the execution of the control transformer with a plurality of secondary windings or taps a plurality of voltages available which can be used for the supply of the control transformer. Due to the different and extending over a larger area power supply of the control transformer results in a correspondingly large control range for the AC voltage to be regulated.
