Abstract
Description
Die Erfindung betrifft ein Verfahren zur Funktionskontrolle in einer unterbrechungsfreien Stromversorgung (USV) sowie eine USV mit einem entsprechend eingerichteten Diagnosemodul.The invention relates to a method for functional control in an uninterruptible power supply (UPS) and a UPS with a correspondingly equipped diagnostic module.
Unterbrechungsfreie Stromversorgungen werden eingesetzt, um empfindliche bzw. wichtige elektrische und elektronische Geräte wie z. B. Computer vor Störungen aus dem Stromversorgungsnetz zu schützen, insbesondere vor einem kompletten Stromausfall.Uninterruptible power supplies are used to power sensitive or critical electrical and electronic equipment such as B. computer to protect against interference from the power grid, especially against a complete power failure.
Aufgabe der vorliegenden Erfindung war es, die Funktionssicherheit einer USV zu erhöhen.Object of the present invention was to increase the reliability of a UPS.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 und eine USV mit den Merkmalen des Anspruchs 2 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen enthalten.This object is achieved by a method having the features of claim 1 and a UPS having the features of claim 2. Advantageous embodiments are contained in the subclaims.
Das erfindungsgemäße Verfahren dient der Funktionskontrolle, einer unterbrechungsfreien Stromversorgung (USV) während des Anfahrens derselben und enthält die folgenden Schritte:
- a) Die Netzspannung aus dem (öffentlichen) Stromnetz wird der zu betreibenden Last zugeführt. Dies geschieht direkt, d. h. ohne Zwischenschaltung der wesentlichen Komponenten der USV, welche für einen Batteriebetrieb während eines Stromausfalls erforderlich sind. Gegebenenfalls können in diesen Schritt untergeordnete Komponenten der USV beteiligt sein, beispielsweise Filter und/oder ein Umschalter.
- b) Parallel zum vorstehenden Schritt a) wird die Netzspannung den (wesentlichen) Komponenten der USV zugeführt, und deren Funktion wird kontrolliert, ohne dass diese ausgangsseitig mit der Last verbunden sind.
- a) The mains voltage from the (public) power grid is supplied to the load to be operated. This is done directly, ie without the interposition of the essential components of the UPS, which are required for battery operation during a power failure. Optionally, subordinate components of the UPS, such as filters and / or a switch, may be involved in this step.
- b) In parallel to the above step a), the mains voltage is supplied to the (essential) components of the UPS, and their function is controlled without these being connected on the output side to the load.
Das Verfahren hat den Vorteil, dass die Funktionsfähigkeit aller Komponenten vor einem länger andauernden Betrieb der USV kontrolliert und sichergestellt werden kann, ohne dass durch die entsprechenden Prozeduren die zu betreibende Last beeinträchtigt wird. Gleichzeitig finden alle Kontrollen unter realistischen Bedingungen statt, da den zu prüfenden Komponenten die tatsächliche Netzspannung zugeführt wird.The advantage of the method is that the functionality of all components can be checked and ensured before the UPS runs longer, without the associated procedures affecting the load to be operated. At the same time, all controls are carried out under realistic conditions, since the actual mains voltage is supplied to the components to be tested.
Die Erfindung betrifft ferner eine unterbrechungsfreie Stromversorgung (USV) mit einem Diagnosemodul, das dazu eingerichtet ist, ein Verfahren der oben beschriebenen Art auszuführen.The invention further relates to an uninterruptible power supply (UPS) having a diagnostic module adapted to carry out a method of the type described above.
Die erfindungsgemäß kontrollierte USV kann vorzugsweise einen Bypass-Schalter enthalten, mit welchem zwischen direktem Netzbetrieb einer Last und gesichertem Umrichterbetrieb der Last umgeschaltet werden kann. Ein derartiger Bypass-Schalter kann dann während der Funktionskontrolle dazu benutzt werden, die Netzspannung direkt an den Verbraucher weiterzuleiten und die Komponenten der USV vom Verbraucher abzukoppeln.The inventively controlled UPS may preferably include a bypass switch, with which between direct grid operation of a load and secured converter operation of the load can be switched. Such a bypass switch can then be used during the functional check to forward the mains voltage directly to the consumer and to decouple the components of the UPS from the consumer.
Die mit dem erfindungsgemäßen Verfahren kontrollierten Komponenten der USV können insbesondere ein Steuerungsmodul für die gesamte USV, einen Gleichrichter, einen Wechselrichter, eine Batterie und/oder eine Batterieschnittstelle umfassen.The components of the UPS controlled by the method according to the invention may in particular comprise a control module for the entire UPS, a rectifier, an inverter, a battery and / or a battery interface.
Im Folgenden wird die Erfindung mit Hilfe der Figur beispielhaft näher erläutert. Die einzige
Die USV
Ferner enthält die USV
Bei dem erwähnten Verfahren handelt es sich um eine Selbstdiagnose beim Anfahren der USV
Die Reihenfolge und die Kombination der Tests gewährleisten, dass keine verborgenen Defekte während der weiteren Inbetriebnahme und dem Betrieb des Systems auftauchen. Da die Selbsttests in einer bestimmten Reihenfolge durchgeführt werden, kann ein Problem fast bis auf das Niveau eines einzelnen Bauteils lokalisiert werden. Dies vereinfacht das Verfahren für Wartungsingenieure bei der Behebung von Störfällen. Ein wichtiger Aspekt ist auch, dass keine zusätzliche Hardware innerhalb oder außerhalb der Standardsysteme benötigt wird, um die beschriebenen Tests auszuführen.The order and combination of tests ensures that no hidden defects will appear during further commissioning and operation of the system. Since the self-tests are performed in a particular order, a problem can be localized almost to the level of a single component. This simplifies the procedure for maintenance engineers to resolve incidents. An important aspect is also that no additional hardware is needed inside or outside the standard systems to perform the described tests.
