Abstract: In order to meet the demand of interconnection of ultra-long distance and large capacity power transmission, one of the feasible schemes is to study direct current (DC) transmission technology with higher voltage level. This paper focuses on the conceptual main circuit design of the ±1 500 kV voltage-class DC transmission,proposes a wiring pattern in which three 12-pulse converter are connected in series. Combined with the characteristics of the wiring type, various DC operation modes including bipolar hybrid voltage mode and bipolar 2/3(1/3) voltage mode are proposed. It also forms a recommended scheme for key equipment parameters such as ±1 500 kV DC engineering converter transformer, smoothing reactor, DC filter and reactive power compensation equipment.

Key words: ±1500 kV, ultra high voltage direct current (UHVDC), main circuit, system design
