Determining armature circuit parameters for direct current machine supplied via current converter involves deriving armature resistance as ratio of smoothed armature voltage and current

摘要

The method involves setting the ignition angle of the current converter (1) valve elements so that the armature current blocks, acquiring the smoothed armature voltage and current measurement values with the machine stationary and deriving the armature resistance as the ratio of the smoothed armature voltage and current measurement values. Several measurements can be made at various ignition angles.
