| description | The invention relates to a power coordinated control method and device for an LCC-VSC direct current transmission system, and belongs to the technical field of direct current transmission. The methodcomprises the steps that the first pole of a VSC end converter station in an active power control mode is switched into a direct-current voltage control mode, and when the second pole of the VSC end converter station is in the active power control mode is in a bipolar active power control mode, an active power reference value is adjusted according to the bipolar active power control mode; when thesecond pole of the VSC end converter station is in a unipolar active power control mode, the active power reference value is unchanged; when the control mode of an LCC end converter station is a bipolar active power control mode, the active power reference value of each pole is adjusted according to the bipolar active power control mode; and when the control mode of the LCC end converter stationis a unipolar active power |
