Method for Determination of a Parameter Set Which Describes Electrical Parameters of a Track Section of a Magnetic Levitation Railroad

A method for determining a parameter set describing electrical parameters of a track section of a magnetic levitation railroad, the track section having a stator section forming a drive section of the magnetic levitation railroad, and a track cable connecting the stator section to a converter device, which comprises the steps of:

• measuring current and voltage values at a first electrical connection point between the track cable and the converter device resulting in measured values;
• measuring current and voltage values measured at a second electrical connection point between the track cable and the stator section, where further current values are measured on a star point side of the stator section when the stator section is electrically connected to the track cable resulting in additional measured values including a measured star point current;
• and
• taking account of the measured values and the additional measured values for determining parameters of the parameter set, and therefore to form the parameter set.
