[0002] Currently, commonly used power system time-domain simulation software monitors simulation progress and analyzes simulation data by using curves output by components. Multiple curves can only be stacked and displayed in the same coordinate system, which consumes a lot of human visual resources. When a large number of curves are stacked, vision can only compare the changing trends of each curve and cannot quickly and accurately obtain detailed information about each curve. Humans perceive the world not only through vision but also through hearing and other senses.

[0003] Therefore, the present invention provides a time-domain simulation method for power systems. Summary of the Invention

[0012] According to the present invention, a power system time-domain simulation method includes enabling sound effects and playing corresponding audio files, comprising:

[0013] Build a sound effects file library, obtain preset audio files or user-uploaded audio files, and assemble audio file packages;

[0014] The audio file packages are categorized and stored according to the category of the power system components corresponding to the primary component model;

[0016] The power system time-domain simulation method provided by the present invention further includes:

[0017] The audio files uploaded by users are tested for audio quality. If the audio quality of the uploaded audio files is not lower than the preset audio quality, the uploaded audio files are deemed to be initially qualified.
