The invention discloses a method for quickly cutting off loads locked by ultra-high-voltage direct current in batches in a concurrence manner. A power grid dispatching automation system serves as a foundation, a switch sequence is selected according to a selection strategy and a filtering condition, a multi-turn control and standby channel control method is adopted, multi-turn control time intervals are adjusted flexibly, batch load cutting-off control success rate is increased greatly, batch loads are cut off quickly by a single-station serial and multi-station parallel combined remote-control mode, batch remote control efficiency is greatly improved, millions of loads can be cut off in minutes, the loads can be quickly controlled in batches on the premise that the safety and the accuracy are ensured when ultra-high-voltage direct current locking fails, and safe and stable running of a power grid is guaranteed.
