Black-start process modeling and analogue simulation method based on isolated power grid

The invention relates to black-start modeling and simulation technology of a power system, in particular to a black-start process modeling and simulation method based on an isolated power grid, whichcomprises the following steps of: inputting basic data and public parameter data; performing data inspection and power flow verification; defining and executing a scheme; judging whether the result isstable; judging whether execution is finished or not; and completing simulation, scheme shaping and recording. Basic data required by black-start modeling is effectively organized in a bus priority mode. A simulation program is established, exact steps and methods are provided for data check and power flow verification, then program simulation is performed on a black-start scheme of a proposed text mode, execution steps of the simulation program can be flexibly adjusted, problems of the scheme under the current standard are found, and a targeted adjustment optimization scheme is provided. Anexact debugging means can b
