Utilizing the Purified Orbit Curve Technical in AP1000 NPP Turbine Diagnosis (Monitoring) Systems Available to Purchase

To improve the diagnosis accuracy and self-adaptability of steam turbine diagnosis systems in AP1000 NPP, this article attempts to apply a new method which unifies digital filter and stimulant filter into the filter processing of turbine Shaft vibration signal in Nuclear Power Plant. According to the process of power plant field data guideline, 4-level Butterworth filter prototype is used to resolve noise influence on original vibration signal. Supported by Matlab ANN Tools and Delphi, this study uses “spline” interpolation in the Process of orbit curve; with an ideal smooth effect achieved after compliance, this practice is proved that it can enhance the recognition effect of in Sanmen AP1000 Nuclear Power Plant TDM(Turbine Diagnosis Systems) monitoring functions.
