description: The work is devoted to the development and software implementation of an algorithm that allows for a comprehensive analysis of an accident. In this work, the following tasks were solved: 1. Familiarization with the COMTRADE waveform format. 2. Selection of the parameter of the electrical circuit, based onwhich the type of damage will be determined.3. Creation of a method for calculating this value. 4. Development of an algorithm for signal segmentation by(quasi-) steady-state. 5. Consideration of methods of filtering the input signal. 6. Development of an algorithm that determines the type of damage. 7. Creation of an algorithm for finding an analytical formula that describes the original signal. 8. Creation of a program for the analysis of an emergency on the basis of the selected algorithms. In this work, a method was considered for calculating the effective values of sinusoidal quantities using a discrete Fourier transform and methods that allow one to determine the type of damage based on the calculated values. The disadvantages of this method were described,and complex resistance was chosen as the value used for the analysis, as well as the methods of its calculation were considered. A brief description of the capabilities of the wavelet transform was given and an algorithm based on it was created, which allows segmenting the signal into sections according to (quasi-) steadystate.Based onthe considered algorithms, a program with a graphical interface was created, which makes it possible to carry out a full-fledged analysis of an accident us-ing COMTRADE format oscillograms as input data.
