Die Hauptpatentanmeldung L 37767/21c betrifft eine Anordnung zum Unterbrechen einer Fernleitung für hochgespannten, über einen aus Transformatoren, Stromrichtergefäßen und Zubehör bestehenden Stromrichter erzeugten Gleichstrom. Im Schaltaugenblick werden der Stromrichter auf Stromlosigkeit gesteuert und unmittelbar anschließend an den Schaltstellen der Fernleitung befindliche Trennschalter geöffnet. Diese Anordnung ist in der Hauptpatentanmeldung erläutert an dem Beispiel von zwei über eine Fernleitung miteinander verbundenen Gleich- und Wechselrichterstationen. Grundsätzlich kann dieser Vorschlag aber auch bei umfangreichen Netzen angewandt werden, an die an mehr als zwei Stellen Gleich- und Wechselrichter angeschlossen sind.The main patent application L 37767 / 21c relates to an arrangement for interrupting a long-distance line for high voltage, via one consisting of transformers, converter vessels and accessories Power converters generated direct current. At the moment of switching, the power converters are controlled to be de-energized and the isolating switches located immediately afterwards at the switching points of the long-distance line are opened. This arrangement is explained in the main patent application using the example of two above a long-distance line connected rectifier and inverter stations. Basically can This suggestion can also be used for extensive networks in more than two places Rectifiers and inverters are connected.

Schon bei einer einfachen Leitung nach dem Ausführungsbeispiel der Hauptpatentanmeldung, erst recht aber bei einem umfangreichen Netz, spielt die Frage des Fehlerschutzes eine große Rolle.Even with a simple line according to the embodiment of the main patent application, only but with an extensive network, the issue of error protection plays a major role.

Die Erfindung betrifft ein Verfahren zum Unter- ao brechen von hochgespanntem, über Transformatoren und Stromrichter erzeugtem Gleichstrom in Netzen mit Hilfe von Trennschaltern. Erfindungsgemäß wird dabei so vorgegangen, daß unmittelbar nach Eintritt eines Fehlers sämtliche mit dem Gleichstromnetz verbundenen Stromrichter mit Hilfe der Gittersteuerung auf Stromlosigkeit gesteuert und kurzzeitig folgend die beiden die fehlerbehaftete Strecke eingrenzenden, nach einem Selektivschutzverfahren ausgewählten Trennschalter geöffnet und danach die Stromrichter des Netzes wieder auf Stromlieferung gebracht werden.The invention relates to a method for sub ao breaking of high-voltage direct current generated by transformers and converters in networks with the help of disconnectors. According to the invention, the procedure is that immediately after occurrence In the event of a fault, all converters connected to the direct current network with the help of the grid control controlled for powerlessness and briefly following the two delimiting the faulty route, disconnector selected according to a selective protection procedure and then the Power converters of the network are brought back to power delivery.

Der Vorschlag geht von der Überlegung aus, daß vorerst keine Schalter für hochgespannten Gleichstrom entwickelt sind, weil ein geeignetes Lichtbogenlöschverfahren noch nicht bekannt ist. Wenn der Vorschlag der Hauptpatentanmeldung auf Netze angewandt wird, so muß für einen einwandfreien Fehlerschutz gesorgt werden. Auf die angegebene Weise ist dies aber leicht möglich dadurch, daß bei Eintritt eines Fehlers alle Stromrichter des Netzes zunächst auf Stromlosigkeit gesteuert werden. Bereits während dieses Vorganges kann nach einem Selektivschutzverfahren mit den hierfür üblichen. Mitteln die fehlerbehaftete Leitungsstrecke ermittelt und dann gefahrlos das Kommando zum Öffnen der beiden diese Strecke eingrenzenden Trennschalter gegeben werden. Danach können alle anderen Stromrichter des Netzes wieder für den Leistungsdurchgang voll geöffnet werden. Hierzu wird man sich der übliehen Gittersteuerung bedienen.The proposal is based on the consideration that initially no switches for high-voltage direct current are developed because a suitable arc extinguishing process is not yet known. if If the proposal of the main patent application is applied to networks, it must be flawless Error protection can be provided. In the manner indicated, this is easily possible in that at If a fault occurs, all power converters in the network are initially controlled to be without power. Already During this process, a selective protection process with the usual. Means the faulty line section is determined and then the command to open the two is safe circuit breaker isolating this route. Then all other converters can of the network can be fully opened again for the passage of power. To do this, one will use the practice Operate the grid control.

Zur Ermittlung des Fehlerortes und der den Fehlerort eingrenzenden Trennschalter dienen an sich bekannte Mittel der Fernmeß- und Fernsteuertechnik, um die zeitgerechte Aufeinanderfolge der Steuerkommandos für Stromrichter und Trennschalter zu bewirken. Dabei werden die notwendigen Verriegelungen vorgesehen, um die einzelnen Vorgänge in der jeweils richtigen Reihenfolge ablaufen zu lassen.To determine the fault location and the isolating the fault location isolating switches are used known means of telemetry and remote control technology to ensure the timely sequence of control commands for converters and disconnectors. This will take the necessary interlocks provided to allow the individual processes to run in the correct order.
