The invention discloses an automatic line pulling control method based on provincial and regional integration, which comprises the steps of: sending a power cutting-off and limiting target command to a regional dispatcher by a provincial dispatcher; automatically receiving a task and sending an alarm by the regional dispatcher, and starting a task processing client; looking up task information by the regional dispatcher through the client and sending a confirming message to the provincial dispatcher; through a power cutting-off and limiting assistant decision client, selecting a power cutting-off and limiting sequence table and a line pulling strategy, combining real time remote signaling and telemetering information of an EMS (Enhanced Message Service) system to automatically generate the line pulling strategy of the target task; and sending a remote control command to a remote RTU (Remote Terminal Unit) terminal through a batch remote control technology. The method provided by the invention realizes integrated close loop operation for cutting off and limiting the power, can cut off the target line in real time efficiently, and powerfully guarantees safe and stable operation of the power grid.
