The invention relates to an electric power system black start on-line navigation type decision recovery method. According to the method, a background decision optimization quasi real-time base, a system state scanning and identifying module, a target network intelligent generation module, a sequence recovery and operation renewal module, a recovery condition statistics module, an industrial experiment guide module, an artificial assigned recovery request module and a recovery scheme display module are included. By means of the method, the recovery state of a system is tracked in real time by monitoring the running state of the system, and then a navigation type network recovery scheme is put forward. First, a target network is loaded to serve as a reference target for the recovery operation, and then the gap between the current actual system state and the target state is judged according to the recovery state statistics. According to the method, the industrial experiment guidance is taken into consideration as well, industrial experiment recovery passageways are recovered at first, and the requirements for the recovery experience and reliability of an actual power grid are met. By means of the method, the real-time running working condition of the system can be tracked, and the on-line navigation type decision recovery scheme can be dynamically generated.
