  • Method for determination of a parameter set which describes electrical parameters of a track section of a magnetic levitation railroad
    Patent number: 8198890
    Abstract: In a method for determining a parameter set describing electric parameters of a route section of a magnetic suspension railway, the route section contains a stator section forming a drive section of the magnetic suspension railway and a route cable connecting the stator section to an associated converter device. In the method, the current and voltage values are measured at the electric connecting point between the route cable and the converter device. The parameters of the parameter set are determined using the measurement values, thus forming the parameter set. Accordingly, the current and voltage values are additionally measured at the electrical connecting point between the route cable and the stator section and the current values at the neutral point side of the stator section, if the stator section is electrically connected to the route cable. The additional measurement values are also considered when determining the parameters.
