Embodiment 1
[0109] In this example, the database of the decision-making system is the bridge connecting the algorithm analysis program, the graphical interface, and the input and output information, and plays the role of storing the original data, saving the calculation process records and calculation information, and outputting the calculation results. The database table of this system includes five major parts (their interrelationships are shown in the appendix figure 2 shown):
[0110] 1) Factory parameters;
[0111] Plant parameter table: including ID, bus name, reference voltage, plant type, plant name, area, region, equipment status.
[0112] 2) Generator parameters;
[0113] Generator basic parameter table: including ID, plant name, unit name, bus name, equipment ownership, rated voltage, rated capacity, maximum active power, minimum active power, maximum reactive power, minimum reactive power, commissioning status, commissioning time, belonging status.

Embodiment 2
[0128] In the system described in Embodiment 1, the system for generating a black boot scheme and system recovery includes three parts: system partition, black boot recovery path generation, and system recovery. attached Figure 4 It is a flow chart of system function.
[0129] System partition:
[0130] In order to restore power supply as soon as possible, a parallel recovery strategy is required. Therefore, it is necessary to divide the large-scale power network into several partitioned networks, and perform independent parallel recovery.
[0131] Parallel recovery can greatly speed up the power system recovery process, mainly to achieve the following three goals:
[0132] 1) Restore the grid power supply in the shortest time.
[0133] 2) The power of the tie line between the sub-divisions is the smallest. The synchronization of each subsystem is an important factor affecting the efficiency of partition recovery. In order to reduce the impact of parallel partition synchr...
Embodiment 3
[0193] In the system described in Embodiment 2, after completing the black start path generation and system recovery calculation, the optimal black start plan has actually been obtained, and the system can export the calculation results to form an initial report of the black start plan, and then schedule On this basis, the staff can simply modify and add explanatory text to form a start-up plan report. The system gives the following black start analysis report:
[0194] 1) The black start path generates a calculation analysis report;
[0195] The report includes the following 7 aspects: each path scheme and display diagram; path line parameters; power frequency overvoltage verification results during startup; no-load line closing operation overvoltage verification results; stability verification results; self-excitation calibration results verification results; small disturbance verification results.
[0196] 2) Black boot system recovery calculation analysis report.
