Abstract: -The power system transients (PST) can cause serious disturbances in the reliability, economy and safety of the power system network. The transient signals are the short term duration for which the frequencies as well as varying time information are compulsory known for the analysis purposes. These disturbances occur for few cycles, which are difficult to be identified and classified by digital measuring and recording instrumentations. For the analysis and detection of PST disturbances (PSTDs) different algorithms have been developed to generate their accurate waveforms. This paper discusses and develops the different simple and efficient simulation models of PST waveforms with spectral and magnitude specifications as guided by IEC and IEEE-1159 through the numerical data. Matlab/Simulink has been utilized for the simulation of different types (like oscillatory and impulse transients) of PST to prove the applicability, validity and accuracy for the detection and analysis of PSTDs.
