Analysis on Harmonic Characteristics and Suppression Method of DC Biasing

摘要：

When operating under ground return mono-polar state, DC transmission systems may cause DC biasing in part of transformers in power system and increase transformer noises, harmonics, losses and the temperature of transformers. In addition, transformers under DC biasing will become harmonic sources in AC system and take serious effect on the power quality. Further study on harmonic characteristics and suppression method of DC biasing under all kinds of complex conditions in the network is of great significance in the safe and stable operation of power systems.
