SELBSTÄNDIGE SYNCHRONISATION PARALLEL GESCHALTETER INDEPENDENT SYNCHRONIZATION PARALLEL SWITCHED
PULSWECHSELRICHTER BEI BAHNFAHRZEUGENPULSE CHARGERS IN RAIL VEHICLES
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 invention relates to a circuit of three-phase pulse inverters in railway vehicles, which generate a three-phase output voltage from a DC input voltage, for the supply of 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 Fig. 1 ersichtlich ist. Es ist weiter bekannt, für das Versorgen von Verbrauchern entweder größere Pulswechselrichter und somit mehr PWR- Leistung zu installieren oder eine Parallelschaltung von Pulswechselrichtern mittels zusätzlicher Daten- Kommunikationsleitung und Master-Slave-Funktionsweise zu realisieren, wodurch letztlich bei Ausfall eines Pulswechselrichters die Verbraucher weiterversorgt werden. Bei Ausfall eines zweiten Pulswechselrichters kommt es häufig bereits zu einem Komplettausfall.In the case of rail vehicles, it is currently customary to install more inverter power than required for the connected power, in order to supply as much of the load as possible to a second redundant pulse inverter even in the event of failure of a pulse-controlled inverter (PWR). At the same time a coupling contactor is necessary for the connection of the redundancy, as shown in FIG. 1 can be seen. It is also known to install either larger pulse inverters and thus more PWR power for supplying consumers or to realize a parallel connection of pulse inverters by means of additional data communication line and master-slave operation, which ultimately the consumers are further supplied in case of failure of a pulse inverter , In the event of failure of a second pulse-controlled inverter, complete failure often already occurs.
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. 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.The invention has for its object to provide a circuit of pulse inverters, in which the availability of the supply of consumers is increased, a greater instantaneous power is available and the total installed pulse inverter power can be reduced. This object is achieved in that a plurality of pulse inverters are connected in parallel and via an implemented in hardware or software control or control structure is an independent synchronization of the pulse inverter to the output voltage and the proportionate supply of consumers.
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 the construction of a 3AC island grid without master-slave function and thus without data communication between the control units of the pulse-controlled inverter solves a previously open in the railway industry problem.
Aus der erfindungsgemäßen Parallelschaltung von Pulswechselrichtern ohne gegenseitige datentechnische Kommunikation ergeben sich insbesondere folgende Vorteile:The following advantages in particular result from the parallel connection of pulse inverters according to the invention without mutual data communication.
• Es steht eine größere momentane Leistung, beispielsweise für einen Kompressoranlauf, zur -Verfügung.• There is a greater instantaneous power, for example for a compressor start-up, to be provided.
• Die Verfügbarkeit der Versorgung von 3AC-Verbrauchern erhöht sich, da ein Ausfall von Pulswechselrichtern stufenweise zu einer Begrenzung der Energieversorgung führt.• 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.
• Die insgesamt installierte Leistung an Pulswechselrichtern kann verringert werden, und zwar von beispielsweise 80OkVA bei der bisherigen Lösung nach Fig. 1 auf 533kVA bei den erfindungsgemäßen Ausführungen nach Fig. 2 und 3.• The total installed power of pulse inverters can be reduced, for example, from 80OkVA in the previous solution of FIG. 1 to 533kVA in the embodiments of the invention according to FIGS. 2 and 3.
• 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.• 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.
• 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.• 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 consumers to be easily and quickly disconnected from the 3AC distribution in the event of a fault.
