In this paper, a fault detection algorithm for multiple grid-connected photovoltaic (GCPV) array configurations is introduced. For a given set of conditions such as solar irradiance and photovoltaic module temperature, a number of attributes such as power, voltage and current are calculated using a mathematical simulation model. Virtual instrumentation (VI) LabVIEW software is used to monitor the...
Noise generated by the large transformers in the urban areas has serious impact on people's daily life and rest. Additionally, the noise as low-frequency noise mainly consists of harmonics of 100Hz. Therefore, adopting active noise control with LMS adaptive filter algorithm can reduce the noise effectively. Through simulation it has been shown that the effect of the step side and the filter order...
Both software and hardware of computer systems are subject to faults, however, traditional approaches, ignoring the relationship between software faults and hardware faults, are unavailable for analyzing complex software and hardware faults. This paper proposes a systematic framework to analyze correlative software and hardware fault. It includes two associated processes, module level analysis and...
