In view of harmonic which generated from the new-type HVDC analog system 12-pulse wave rectifiers and the inverter, designed passive filters system based on the new-type converter transformer. Through theory inferential reasoning and analysis, determined systemic harmonic components. In the proper attention to both the foundation of harmonic content, the reactive power compensation quantity and the harmonic filtration rate, considering the investment cost as well as the filter effect, established the filter structure and the form, and has given the design example. Through the simulation computation, validated that the passive filter system which based on the new-type converter transformer has good filtering performance and reactive power compensation, explained the accuracy of the design method. This method has instruction and reference value to actual project.
