CONSTITUTION: The reactive power control filer SC is connected to the secondary side of receiving transformer Trs and also to the primary side of the feeding transformer TrF
1-n , and the fifth harmonic resonance filter fil
51-5n , the seventh harmonic resonance filter fil
71-7n , and the eleventh harmonic resonance filter fil
11-11n are connected to the secondary side of the feeding transformer. In such a constitution, the composite impedance |ASN| seen power source side in an even-numbered harmonic wave more than the fourth harmonic wave shows low impedance, but the |ZSN| shows a comparatively high impedance even if there is a higher harmonic electromotive force more than the fifth harmonic wave which comes into question for actual power wave-form strain, so that the development of strain in the wave- form of power source can be lessened. Also, the composite impedance |ZRN| seen from electric car establishs a nearly short-circuit in the fifth, seventh, and eleventh harmonic current sources of higher harmonic electromotive force for electric car line.
