Embodiment 1

[0109] In this example, the database of the decision-making system is a bridge connecting the algorithm analysis program, graphical interface, and input and output information, and plays the role of storing original data, saving calculation process records and calculation information, and outputting calculation results. The database table of this system contains five parts (their interrelationships are as attached figure 2 shown):

[0110] 1) Factory station parameters;

[0111] Plant parameter table: including ID, bus name, reference voltage, plant type, plant name, area, region, and equipment status.

[0112] 2) generator parameters;

[0113] Generator basic parameter table: including ID, station name, unit name, bus name, equipment ownership, rated voltage, rated capacity, maximum active power, minimum active power, maximum reactive power, minimum reactive power, operating status, operating time, belonging state.

[0114] Generator model parameter table: including ID, ...

Embodiment 2

[0128] In the system described in embodiment 1, the generation of black boot scheme and system recovery system comprise three major parts: system partition, black boot recovery path generation, system recovery. attached Figure 4 It is a flow chart of the 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 partition networks and perform independent parallel restoration. Finally, the partitions are interconnected through simultaneous operations to restore power supply to the entire system.

[0131] Parallel restoration can greatly speed up the power system restoration 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 connecting line between the sub-regions is the smallest. The synchronization of each subs...

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 solution has actually been obtained, and the system can export the calculation results to form an initial report of the black start solution, 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 boot analysis report:

[0194] 1) Generate a calculation and analysis report for the black start path;

[0195] The content of the report includes the following 7 aspects: each path scheme and display diagram; path line parameters; power frequency overvoltage verification results during start-up process; no-load line closing operation overvoltage verification results; stability verification results; self-excitation calibration test results; small perturbation test results.

[0196] 2) Black boot system recovery calculation analysis ...

Abstract

The invention provides a black-start path generation and system recovery decision-making system based on a 3D visualization technology, which is used for power grid black-start and power grid rapid recovery after large-area power failure, and is characterized in that the decision-making system comprises a graphical interface module, a database and an algorithm function library; the graphical interface module comprises a graphical configuration software system and a 3D graphical system and is used for generating a plant station diagram, a grid frame plane diagram and a grid frame diagram of a 3D actual geographical background of a power system; the database can import power system data in BPA and CIME formats through a data conversion interface, and the power system data comprises element parameters and corresponding calculation results; the algorithm function library comprises a black-start scheme and an algorithm program for numerical analysis, simulation and optimization in a systemrecovery process so as to realize partitioning, black-start path generation, verification, evaluation and system recovery functions; according to the invention, the problem of heavy workload of calculation, analysis, writing and the like of a black-start scheme of a scheduling operator can be overcome.

Description

technical field [0001] The invention relates to the field of power grid black start technology, in particular to a black start path generation and system recovery decision system based on 3D visualization technology. Background technique [0002] Since the 1950s and 1960s, thousands of experts and scholars at home and abroad have devoted themselves to the study of various advanced strategies, theories and methods to reduce the probability of power system accidents. Although fruitful results have been achieved, The level of automation and informatization of the system has been greatly improved, and the frequency of system accidents and large-scale power outages has been greatly reduced; however, the occurrence of large-scale power outages cannot be completely avoided. Once a large-scale power outage occurs in the system, the longer the power outage, the greater the political and economic losses. Therefore, after a large-scale power outage occurs in the system, how to quickly...
