Techniques for conducting an air flow simulation for a wind turbine include importing a file containing a digitized representation of a three-dimensional blade geometry, extracting from the file, blade constructive parameters, and calculating a low-order air flow past a wind-turbine that includes the blade, based on a Blade Element Momentum Theory (BEMT) to determine sectional angle of attack and free-stream velocity, boundary layer transition, and acoustic noise results. The techniques also include performing air flow simulation for a given number of blade sections, and generating virtual microphone rings. The process also includes computing noise spectra at the virtual microphone rings and blending the noise spectra generated and generating synthetic noise signals from each section by inverse Fourier transform of the noise spectra and converting the noise spectra into an audio track.

A simulation system and a method thereof are disclosed. In the simulation system, a system power transmission model, and analog current time-domain model and digital current time-domain model are connected to obtain power noise generated after a supply current is obtained; jitter time-domain information of each interface connection circuit model under the power noise is obtained based on transmission of a clock signal outputted from a phase lock loop, by a simulation program; next, a voltage step response of a voltage measurement point when a clock terminal of each interface connection circuit model receives an ideal signal, is simulated by the simulation program to generate a first voltage time-domain model; a system waveform is generated based on the jitter time-domain information of each interface connection circuit model under the power noise, the first voltage time-domain model and data transmission, thereby obtaining an eye diagram and time-domain jitter distribution.
