Abstract

The paper presents a vector control with two cascaded loops to improve the properties of Dynamic Voltage Restorer (DVR) to minimize Voltage Sags on the grid. Thereby, a vector controlled structure was built on the rotating dq-coordinate system with the combination of voltage control and the current control. The proposed DVR control method is modelled using MATLAB-Simulink. It is tested using balanced/ unbalanced voltage sags as well as fluctuant and distorted voltages. As a result, by using this controlling method, the dynamic characteristics of the system have been improved significantly. The system performed with higher accuracy, faster response and lower distortion in the voltage sags compensation. The paper presents real time experimental results to verify the performance of the proposed method in real environments. [ABSTRACT FROM AUTHOR]

5. The study on crystal structure of Ni deposits plated in supercritical CO 2 method

Abstract

Recently, the results of an electrodeposition of nickel showed that the coating plated in supercritical carbon dioxide, Sc-CO 2 , emulsion has smaller grain size, higher hardness, excellent coverage, low surface roughness and pinhole-free microstructure over its conventional counterpart. It was found that, even without the addition of surfactant in the electrolyte, similar improvement over the coating properties was also obtained. However, the presence of surfactant in the Sc-CO 2 electrolyte resulted in a predominant preferred {111} texture. Meanwhile, adjusting boric acid up to 15 g/L and decreasing current density to 5 A/dm 2 resulted in more preferred {111} Ni crystalline as well. In addition, the use of pulse current in the Sc-CO 2 electroplating further modified Ni crystal from {200} to {111} orientation.
