The invention discloses an intelligent training simulation system for processing power transformation operation and maintenance accidents. The intelligent training simulation system comprises a control layer, an information layer and a display layer, wherein the control layer is configured to read multipoint sampling data, submit the data to the information layer and simulate and display working processes of opening and closing of switches and disconnecting links and switching of protection pressing plates during an accident handling process through flash graphic interaction and frame technologies; the information layer is configured to realize remote control and dispatch in a B/S mode and ensure the security of Internet interaction by arranging a firewall or a proxy server; and the display layer is used for feeding back data variation conditions of the information layer and displaying the interaction information of the control layer. The intelligent training simulation system has the advantages of wide applicability and accurate simulation ability.
