英文摘要 | Fourier analysis techniques were used to analyze the noisy data arising from temperature and pressure readings of certain trial runs of the Automatic Depressurization System (ADS) component of the Nuclear Reactor System AP600. The data consists of temperature and pressure readings of water and steam in a system of pipes and valves, and a filter for this data is proposed. This filter uses a discrete Fourier transform program, a discrete Fast Fourier transform program, and other numerical methods. One feature of this filter is its use of the discrete derivative of the pressure readings, and the object of this filter is to reduce the great fluctuations present in the raw data. |
