The invention relates to a double-winch lifting and active compensation system suitable for a double-derrick drilling machine. The system comprises derricks, crown blocks, a winch platform, double winches, runner wagons and a traction rope. The derricks are arranged above a wellhead; the crown blocks are arranged at the tops of the derricks and each comprise a crown block pulley group consisting of a plurality of pulleys; the winch platform is arranged on one side of the lower parts of the derricks; the double winches comprise the first winch and the second winch, and the first winch and the second winch are both arranged on the winch platform; the runner wagons are arranged in the derricks and each comprise a runner wagon pulley group consisting of a plurality of pulleys; and the tractionrope is led out to the runner wagon pulley groups through the first winch firstly, then led to the runner wagon pulley groups through the crown block pulley groups, then returned to the crown block pulley groups, and finally led out to the second winch through the crown block pulley groups.
