Identification of Flicker Source Using Continuous Wavelet Transform
نویسندگان
چکیده
In this paper, a method based on continuous wavelet transform is suggested for calculation of flicker power. The flicker power can be utilized to identify the flicker direction to a flicker source with respect to a monitoring point. In our proposed method, using continuous Gaussian wavelet transform, pure flicker waveforms are extracted from the measured voltage and current signals. The flicker power can then be calculated. The direction to a flicker source is obtained from the sign of this flicker power. The proposed algorithm is tested using IEEE 13 Node Test Feeder. The simulation results validate the effectiveness of the proposed method. KeywordsPower quality; Flicker direction; Flicker power; Continuous wavelet transform.

Improving the Method of Location Identification and Determining the Effect of Each Flicker Source in Distribution Networks
Voltage flicker phenomenon is one of the main power quality problems in today's power networks. Before any compensation operation for this phenomenon, the location of each flicker sources must be identified and the effect of each of them on the network flicker value must be determined. Also, methods that require least number of monitoring points are more in demand due to the limitations of meas...
متن کاملDamage identification of structures using experimental modal analysis and continuous wavelet transform
Abstract: Modal analysis is a powerful technique for understanding the behavior and performance of structures. Modal analysis can be conducted via artificial excitation, e.g. shaker or instrument hammer excitation. Input force and output responses are measured. That is normally referred to as experimental modal analysis (EMA). EMA consists of three steps: data acquisition, system identificatio...

Electric Arc Furnaces (EAFs), widely used for steel production industries, are highly nonlinear time-variant disturbing loads because of the random change of the electric arc length results in arc voltage and furnace/supply current fluctuations. Consequently, Power Quality (PQ) problems such as undesirable variations of reactive power, poor power factor, harmonics, and voltage flickers may appe...
