摘要
Abstract
When the UHVDC(ultra high voltage direct current)transmission using unipolar—earth mode,the DC (direct current)current through the transformer in the AC system will produce DC bias. Through the analysis of the flow path and current parameters of the DC circuit,and the appropriate suppression method was chosen which could effectively solve the problem of DC bias. Based on the Jiuquan converter station of the Jiuquan to Hunan ± 800 kV HVDC transmission engineering,firstly,the process of DC bias and its influence on the surrounding AC substation were analysed. Then,the influence of DC bias was analysed by the actual test. Finally,the suppression methods of DC bias were studied.关键词
