Harmonic Model of New Type Converter Transformer and Its Filter Equipments Design

The operating principle and the harmonic suppression scheme of a new-type converter transformer and its filtering system were described.The harmonic model new-type converter transformer and its filtering system were established and the harmonic current distribution were analyzed and calculated,and the reliability of the harmonic model was verified through experiments.It was the foundation for parameters design of the filtering system,and the DC transmission system exploitation platform was taken as an example for the filtering system design.The simulation results was closely correspondent to the testing experiments,and it has been shown that the theoretical analysis of the new-type converter transformer and its filtering system is correct,the parameters of the platform are proper,and the filtering system works effectively,It has a good application prospect.
