Abstract:

Special field test has very important sense to enhance the grid detection level of power equipment and the quality, efficiency of UHVDC transmission project. Combined with ±800 kV Yunguang and Puqiao DC transmission project, this paper compared and analysed the characteristics and application range of series resonance and parallel resonance. Combined with the long-duration induced AC voltage (ACLD) test and AC applied test of converter transformer, the application method and key technology of resonance test apparatus in UHVDC transmission project construction had been studied, which had reference and guiding significance for the special field tests of subsequent UHVDC transmission project.

Key words: series resonance, parallel resonance, converter transformers, field test
