The invention discloses a power grid power transmission line power emergency control method, which comprises the following steps of: extracting power grid state information from a real-time section power flow file of a power grid, inputting the power grid state information into a constructed and trained power grid power transmission line power control model, and outputting a power control action with the highest expected reward value. The actual reward value generated by executing the control action is obtained after the power control action is executed, meanwhile, the power grid power transmission line power control model is updated, the control process does not depend on a power grid model, when the power transmission line out-of-limit problem is detected, the control action and the expected effect can be given in time, real-time power transmission line power control is achieved, and the control efficiency is improved. Compared with an existing algorithm depending on a power grid model or an optimal power f
