In order to study the feasibility ofrespective control mode that high voltage side valve group and low voltage side valve group in a single poleare respectively controlled, and the merits and demerits of this mode and jointcontrol modethattwo 12-pulse converter groups are jointlycontrolled in UHVDC power transmission systems simulation.±800 kV UHVDC transmission project model is set up. The operation characteristics of steady state and deblocking and blocking of high voltage side valve group are simulated. The comparison and analysis results show that: steady-state simulation waveforms of the two control mode can be a good correspondence; the basic strategies of blocking and deblockingare same, the dynamic characteristics are similar; therespective control mode is entirely feasible in UHVDC power transmission systems simulation.
