Description
Die Erfindung betrifft ein Verfahren zur Bestimmung der Wirkleistung eines elektrischen Drehstrommotors, bevorzugt eines Weichenantriebs, mit mindestens zwei Stromkreisen, mit jeweils mindestens einer Motorwicklung, und eine elektronische Weichensteuerung zum Durchführen des Verfahrens sowie ein Weichenantriebssystem mit einer derartigen elektronischen Weichensteuerung. Die Schrift JP 02197460 offenbart ein überwachungssystem für elektrische weichenantriebe.
Ein Weichenantriebssystem verfügt über ein oder mehrere, an verschiedenen Orten entlang einer Weiche mit einer Weichenzunge positionierten Weichenantrieben zur Einstellung der Weichenzunge. Derartige Weichenantriebssysteme werden in Eisenbahnschienennetzen bei Eisenbahnweichen eingesetzt. Das erfindungsgemäße Verfahren dient der Diagnose der Weiche, insbesondere der Ermittlung des Wartungszustandes der Weiche während des Bahnbetriebs.The invention relates to a method for determining the active power of an electric three-phase motor, preferably a points drive, with at least two circuits, each having at least one motor winding, and an electronic switch control for performing the method and a points drive system with such electronic switch control. The document JP 02197460 discloses a monitoring system for electric soft drives.
A turnout drive system has one or more turnout drives positioned at various locations along a turnout with a switch tongue for adjusting the switch point. Such point drive systems are used in railway rail networks at railway points. The method according to the invention serves to diagnose the switch, in particular the determination of the maintenance state of the switch during rail operation.
Insbesondere, wenn derartige Weichen mit hohen Geschwindigkeiten befahren werden, muss der Wartungszustand der Weiche ständig überwacht werden, um den Sicherheitsanforderungen an den Betrieb einer derartigen Bahnweiche gerecht zu werden. Zum Umstellen der Weiche wird bei gebräuchlichen Weichenantriebssystemen ein mechanisches Weichengestänge, das von einem Weichenantrieb bewegt wird, benutzt. Durch Umwelteinflüsse, wie Verschmutzung und/oder Korrosion, kann es zu einer Schwergängigkeit der Weichenzunge kommen, die zu Störungen beim Umstellen führen kann.In particular, when such switches are driven at high speeds, the maintenance status of the switch must be constantly monitored to meet the safety requirements for the operation of such a railway switch. To switch the switch is used in conventional point drive systems, a mechanical point linkage, which is moved by a switch mechanism used. Environmental influences, such as soiling and / or corrosion, can lead to a stiffness of the switch tongue, which can lead to disturbances during switching.
Jeder Weichenantrieb wird über mindestens eine Vierdrahtschnittstelle von einem Stellwerk aus gesteuert und mit einer Betriebsspannung versorgt. Die Vierdrahtschnittstelle verfügt über vier Adern, wobei zwei mit phasenverschobenen Wechselspannungen beaufschlagt sind. Eine derartige Vierdrahtschnittstelle stellt eine Standardschnittstelle für Bahnweichen (Kabelendverteiter) dar, die für den Betrieb einer Weiche mit einem einzigen Weichenantrieb und einem einzigen Zungenprüfkontakt bei üblichen Bahnschienennetzen verwendet wird.Each turnout drive is controlled by at least one four-wire interface from an interlocking and supplied with an operating voltage. The four-wire interface has four wires, two of which are subjected to phase-shifted AC voltages. Such a four-wire interface provides a standard interface for diverter (cable end-of-line) used to operate a single point-and-turn diverter with a single tongue test contact on conventional railroad networks.
Zur Überwachung des Wartungszustandes der Weiche kann beim Umstellvorgang die aufgenommene Leistung des Weichenantriebs über eine Leistungsmessung bestimmt werden und daraus eine Diagnose über eine Schwergängigkeit der Weiche (Schwergang) abgeleitet werden. Über diese Diagnose kann die Entscheidung, ob eine Wartung eingeleitet wird getroffen werden. Dazu ist es notwendig, den momentanen Leitungs- inklusive Blindwiderstand der angeschalteten Stromkreise, d.h. der Kabel und sonstiger Bauelemente, und damit die Verlustleistung zu kennen, um die für die Umstellung der Weiche vom Weichenmotor aufgenommene Leistung (Wirkleistung) möglichst exakt zu bestimmen, denn die Gesamtleistungsaufnahme des Weichenantriebs setzt sich additiv aus der Wirkleistung und der Verlustleistung zusammen.To monitor the maintenance condition of the switch, the absorbed power of the switch drive can be determined by means of a power measurement during the changeover process, and from this a diagnosis can be derived by means of a stiffness of the switch (heavy gear). This decision can be made to decide if maintenance will be initiated. For this purpose, it is necessary to determine the instantaneous line-included reactance of the switched-on circuits, i. the cable and other components, and thus to know the power loss to determine the recorded as the changeover of the switch from the point motor power (active power) as accurately as possible, because the total power consumption of the points drive is composed of the active power and the power loss together.
Es ist gebräuchlich, die Verlustleistung aus einem aus den Plänen der Anlage, d.h. des Weichenantriebs, berechneten Leitungswiderstand zu berechnen. Dabei wird jedoch eine temperaturbeeinflusste Änderung des Leitungswiderstandes beim Betrieb des Weicheantriebs nicht berücksichtigt, was zu einem nicht tolerierbaren Fehler bei der Bestimmung der Wirkleistung führt.
Weiter existieren Lösungen, bei denen der Leitungswiderstand mittels Gleichstrom gemessen wird, was zumindest den Blindwiderstand und damit den Blindanteil der Leistung des Motors des Weichenantriebs eliminiert. Diese Lösungen erfordern jedoch zusätzlichen Schaltungsaufwand bei der Steuerung des Weichenantriebs (Weichensteuerung), was zu Zusatzkosten bei der Herstellung des Weichenantriebs führt.It is customary to calculate the power loss from a line resistance calculated from the plans of the plant, ie the points drive. there However, a temperature-influenced change in the line resistance is not taken into account during operation of the soft-drive, resulting in an intolerable error in determining the active power.
Furthermore, there are solutions in which the line resistance is measured by means of direct current, which eliminates at least the reactance and thus the reactive power of the motor of the points drive. However, these solutions require additional circuit complexity in the control of the point machine drive (switch control), which leads to additional costs in the production of the points drive.

- Turnout diagnostic systems can be integrated into the turnout control. Integrating the diagnosis into the control leads to a reduction in costs.
- The application of the method is particularly suitable for high-speed points on high-speed lines, which must be monitored very strong safety.
- The determination of the active power and thus the effective resistance can be made with present in known switch drive systems transducers. Additional components are not necessary for this.
- The determination of the effective resistance can be made immediately before their conversion. Changes in the effective resistance between the measurement and the point changeover therefore do not occur.
- The method is particularly suitable for microcomputer-controlled point controllers and can be implemented there by simply importing software with code sections which control the execution of the method according to the invention.
Besonders bevorzugt wird das Beaufschlagen des ersten und des zweiten Stromkreises mit jeweils einer Wechselspannung zum Zeitpunkt eines Nulldurchganges der jeweiligen Wechselspannung vorgenommen, wobei die Messung des im ersten Stromkreis fließenden elektrischen Stroms und des Phasenwinkels zwischen der ersten Wechselspannung und dem gemessenen Strom in einem Zeitintervall zwischen dem Beaufschlagen der Wechselspannungen vorgenommen wird. Dadurch werden ausschließlich Blindleistungen und Leistungsverluste durch Leitungswiderstände bei der Messung berücksichtigt, da der Drehstrommotor erst nach Beaufschlagung beider Stromkreise mit einer phasenverschobenen Wechselspannung Wirkleistung aufnimmt, indem er mechanische Arbeit verrichtet.The measurement of the electrical current flowing in the first circuit and of the phase angle between the first alternating voltage and the measured current in a time interval between the first alternating current and the second alternating current is particularly preferred Applying the AC voltages is made. As a result, only reactive power and power losses due to line resistances are taken into account in the measurement, since the three-phase motor does not pick up active power until it has acted upon both circuits with a phase-shifted AC voltage by performing mechanical work.

Durch die Kontakte im Weichenantrieb 3 existieren beim Einschalten zwei Stromkreise 1,2. Ein Stromkreis von einem Aussenleiter L nach dem Vierdrahtschnittstellenkontakt N mit einer Motorwicklung 4 und ein zweiter Stromkreis von einem Aussenleiter L zu einem weiteren Aussenleiter L mit zwei eingeschalteten Motorwicklungen 4. Durch das Schalten im Nulldurchgang der Spannung wird zuerst ein Stromkreis 1 eingeschaltet und der zweite entsprechend dem durch die Netzfrequenz gegebenen Raster in einem Zeitintervall Δt später. In diesem Zeitintervall werden die Messungen zur Bestimmung des Wirkwiderstandes durchgeführt.
Es werden die Spannung, der Strom und der Phasenwinkel bei noch stillstehendem Motor bestimmt. Daraus wird der Wirkwiderstand des Stromkreises bestimmt. Der Motor läuft erst an, wenn eine Spannung an den zweiten Stromkreis angelegt wird und dadurch ein Drehfeld anliegt. Die Wirkwiderstandsbestimmung kann in beiden Stromkreisen 1,2 vorgenommen werden. Welcher Stromkreis dazu verwendet wird, kann in der Implementierungsphase des Weichenantriebssystems entschieden werden oder die Weichensteuerung verfügt über Mittel zur Umschaltung, eingerichtet um die Wirkwiderstandsbestimmung in Abhängigkeit von Steuerbefehlen entweder im ersten oder im zweiten Stromkreis durchzuführen.In Fig. 1, an inventive switch operating system is shown with an electronic switch controller 10 according to the invention for carrying out the method according to the invention.
