Noise Cancellation and Feature Generation of Voltage Disturbance for Identification Smart Grid Faults

IEEE 16th International Conference on Environment and Electrical Engineering (EEEIC) -- JUN 06-10, 2016 -- Florence, ITALY Yalcin, Turgay/0000-0002-6400-4786 WOS: 000387085800382 Identification of system disturbances and detection of them guarantee smart grids power quality system reliability and long lasting life of the power system. The key goal of this study is to generate non - time consuming features for CPU, for recognizing different types of non-stationary and non-linear smart grid faults based on signal processing techniques. This paper proposes a new solution for real time power system monitoring against power quality faults focusing on voltage sag and noise. EEMD is used for noise reduction with first intrinsic mode function ( imf1). Hilbert Huang Transform ( HHT) is used for generating instantaneous amplitude ( IA) and instantaneous frequency ( IF) feature of real time voltage sag power signal. PQube, power quality and energy monitor was used to acquire the distortions, several other parameters such as Total Harmonic Distortion ( THD). The proposed power system monitoring system is able to detect power system voltage sag disturbances and capable of recognize and remove EMI ( Electromagnetic Interference)- Noise.
