Analysis of doubly fed induction generator wind turbine system during one phase-to-ground fault
(2013)
This paper presents detailed analysis of doubly fed induction generator (DFIG) wind turbine electrical components during normal and unbalanced fault condition. Wind turbine components are individually modeled and then ...
Continuous wavelet transform for ferroresonance phenomena in electric power systems
(Elsevier Sci Ltd, 2013)
The common characteristics of a nonlinear system are multiple equilibrium points, limit cycles, jump resonance and sub-harmonic generation. Ferroresonance is also a nonlinear electrical phenomenon, which occurs frequently ...
Spectral and Statistical Analysis for Ceramic Plate Specimens Subjected to Impact
(Trans Tech Publications Ltd, 2013)
In this study, ceramic plate behaviour was elaborated on the basis at sound signal variations caused by the impact. All tests were performed using plate specimens and pendulum testing station; with date acquisition and ...
The defect detection in ceramic materials based on wavelet analysis by using the method of impulse noise
(Jve Int Ltd, 2013)
In this experimental study, it was achieved to detect internal or surface cracks that can occur in the production of ceramic plates by using the method of impulse noise. This method is a test technique which was not used ...
Continuous Monitoring of Water Quality Using Portable and Low-Cost Approaches
(Sage Publications Inc, 2013)
Water quality refers to the physical, chemical, and biological characteristics of water, and it is a measure of the condition of water relative to any human need or purpose. A particular problem with measuring the condition ...
Free Vibration Analysis of Asymmetric-Plan Shear Wall and Core Buildings Using One-dimensional Finite Element
(Springer Heidelberg, 2013)
In this study, a method is presented for free vibration analysis of multi-storey asymmetric structures whose bearing system is composed of shear walls and cores. The multi-storey structure was modeled as an equivalent ...
Free Vibration Analysis of a Thin-Walled Beam with Shear Sensitive Material
(Hindawi Ltd, 2013)
This paper presents a method for a free vibration analysis of a thin-walled beam of doubly asymmetric cross section filled with shear sensitive material. In the study, first of all, a dynamic transfer matrix method was ...
Reliability Analysis of Hybrid Energy Systems: Case Study of Davutpasa Campus
(Ieee, 2013)
In recent years, sustainable and clean renewable energy resources are widely used instead of fossil fuel energy resources in electrical energy generation systems. Especially, wind and solar energy conversion systems are ...
Statistical Analysis and Hurst Parameter Estimation for Wind Speed in Kirklareli Area of Turkey
(Ieee, 2013)
In this study, a wind speed data of the Klrklareli region of Turkey is considered and Hurst parameter is calculated for this data. For this purpose at first statistical parameters of the wind speed data are calculated. ...
Assessment of scaling properties of groundwater with elevated sulfate concentration: a case study from Ergene Basin, Turkey
(Springer Heidelberg, 2013)
In this study, the Langelier saturation index and the Ryznar stability index of the groundwater of the east of Ergene Basin were evaluated to assess the corrosivity or scale-forming tendencies. Corrosion is one of the most ...
