Abstract
Bei einer Schaltung von dreiphasigen Pulswechselrichtern bei Bahnfahrzeugen, die aus einer DC-Eingangsspannung eine dreiphasige Ausgangsspannung erzeugen zur Versorgung von 3AC-Verbrauchern, sind mehrere Pulswechselrichter parallel geschaltet, wobei über eine in Hard- oder Software realisierte Regel- bzw. Steuerstruktur eine selbständige Synchronisation der Pulswechselrichter auf die Ausgangsspannung und die anteilige Versorgung der Verbraucher erfolgt.In a circuit of three-phase pulse-controlled inverters in railway vehicles, which generate a three-phase output voltage from a DC input voltage for supplying 3AC consumers, several pulse inverters are connected in parallel, via a realized in hardware or software control or control structure, an independent synchronization of Pulse inverter to the output voltage and the proportionate supply of the consumer takes place.
Description
Die Erfindung betrifft eine Schaltung von dreiphasigen Pulswechselrichtern bei Bahnfahrzeugen, die aus einer DC-Eingangsspannung eine dreiphasige Ausgangsspannung erzeugen, zur Versorgung von 3AC-Verbrauchern.The The invention relates to a circuit of three-phase pulse inverters for railway vehicles, the three-phase output voltage from a DC input voltage generate to supply 3AC consumers.
Bei
Bahnfahrzeugen ist es derzeit üblich, mehr
Umrichterleistung als für
die angeschlossenen Leistungen erforderlich zu installieren, um
auch bei Ausfall eines Pulswechselrichters (PWR) einen möglichst
großen
Teil der Last durch einen zweiten redundanten Pulswechselrichter
zu versorgen. Zugleich ist für
die Zuschaltung der Redundanz ein Koppelschütz notwendig, wie aus
Der Erfindung liegt die Aufgabe zugrunde, eine Schaltung von Pulswechselrichtern aufzuzeigen, bei der die Verfügbarkeit der Versorgung von Verbrauchern erhöht ist, eine größere momentane Leistung zur Verfügung steht und die insgesamt installierte Pulswechselrichterleistung verringert werden kann.Of the Invention is based on the object, a circuit of pulse inverters show the availability the supply of consumers is increased, a greater instantaneous performance to disposal stands and the total installed pulse inverter power can be reduced.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass mehrere Pulswechselrichter parallel geschaltet sind und über eine in Hard- oder Software realisierte Regel- bzw. Steuerstruktur eine selbständige Synchronisation der Pulswechselrichter auf die Ausgangspannung und die anteilige Versorgung der Verbraucher erfolgt.These Task is inventively characterized solved, that several pulse inverters are connected in parallel and via a implemented in hardware or software rule or control structure a independent Synchronization of the pulse inverters to the output voltage and the proportionate supply of consumers takes place.
Die Parallelschaltung von Pulswechselrichtern (PWR) zum Aufbau eines 3AC-Inselnetzes ohne Master-Slave-Funktion und damit ohne Daten-Kommunikation zwischen den Steuereinheiten der Pulswechselrichter löst ein bisher in der Bahnindustrie offenes Problem.The Parallel connection of pulse inverters (PWR) for setting up a 3AC island network without master-slave function and thus without data communication between the control units of the pulse inverter triggers a so far in the railway industry open problem.
Aus der erfindungsgemäßen Parallelschaltung von Pulswechselrichtern ohne gegenseitige datentechnische Kommunikation ergeben sich insbesondere folgende Vorteile:
- • Es steht eine größere momentane Leistung, beispielsweise für einen Kompressoranlauf, zur Verfügung.
- • Die Verfügbarkeit der Versorgung von 3AC-Verbrauchern erhöht sich, da ein Ausfall von Pulswechselrichtern stufenweise zu einer Begrenzung der Energieversorgung führt.
- • Die
insgesamt installierte Leistung an Pulswechselrichtern kann verringert
werden, und zwar von beispielsweise 800kVA bei der bisherigen Lösung nach
1 auf 533kVA bei den erfindungsgemäßen Ausführungen nach2 und3 . - • Koppelschütze zur Konfiguration der Redundanz können entfallen.
- • Steuer- bzw. Datenleitungen für die Kommunikation der Pulswechselrichter – etwa zur Synchronisation oder zur Sicherstellung eines Master-Slave-Betriebes können entfallen.
- • Aufgrund des Strombegrenzungsmodes des Pulswechselrichter-Systems und der höheren verfügbaren momentanen Leistung können durch Schutzelemente (z. B. Motorschutzschalter) separierbare Verbraucher im Fehlerfall problemlos und schnell von der 3AC-Verteilung getrennt werden.
- • There is a greater instantaneous power available, for example for a compressor startup.
- • The availability of the supply of 3AC consumers increases because a failure of pulse-controlled inverters gradually leads to a limitation of the energy supply.
- • The total installed power of pulse inverters can be reduced, for example, from 800kVA in the previous solution
1 to 533kVA in the embodiments according to the invention2 and3 , - • Coupling contactors for configuring the redundancy can be omitted.
- • Control or data lines for the communication of the pulse inverters - for example, for synchronization or to ensure a master-slave operation can be omitted.
- • Due to the current-limiting mode of the pulse-inverter system and the higher instantaneous power available, protective devices (eg motor-protective circuit-breakers) allow separate separable loads to be easily and quickly disconnected from the 3AC distribution in the event of a fault.
