Fuzzy Controlled Ultra-Capacitor Based DVr (UCAP-DVr) for Power Quality Enhancement

引用

Circuits and Systems 2016年第13期7卷 4098-4112页

作者： r. Bhavani dr. N. rathina Prabha Department of Electrical and Electronics Engineering Mepco Schlenk Engineering College Sivakasi India

In recent years, a rapid decrease in the cost of various energy storage technologies and their integration into grid becomes a reality with the advent of smart grid. The Dynamic Voltage restorer (DVr) is a custom power device that has an excellent dynamic capability used to provide voltage sag, swell compensation in distribution systems. Among the energy storage devices, Ultra-Capacitors (UCAP) have ideal characteristics such as high power and low energy density essential for the compensation of voltage sag and swell, which require high power for short interval of time. This paper presents an integration of rechargeable UCAP with DVr. This UCAP-DVr presents a modular, flexible system configuration that will have an active power capability and also provide deep, extended mitigation for power quality problems. The DVr is integrated into UCAP via bidirectional DC-DC converter which supports a rigid dc-link voltage for DVr and also helps in compensating temporary voltage sag and swell. FUZZY LOGIC Controller is used to enhance the performance of UCAP-DVr. The simulation model for the proposed system has been developed in MAT-LAB and the performance over conventional DVr is compared with the results obtained.

Four Dawson type heteropolyoxotungstates substituted by noble metals with the general formula (TBA)(n)[As2W17M(OH2)O-61], where M=Pd-II, ru-III, Ir-IV and Pt-IV are prepared by filling thp meant site of thp lacunary percursor alpha(2)-K10As2W17O61. UV-vis and Ir spectra are similar to the other transition metal substituted Dawson type tungstodiarsenates. EPr result provides direct evidence to identify the presence of noble metal cation. Electrochemical behavior investigated bg cyclic voltammetry irt acetonitrile displays four reversible one-electron redox couples attributed to the W(VI-->V) process of tungsten-oxo framework.

AIM： To characterize the clinical, serologic and virologic features of hepatitis B virus （HBV） infection in Iranian patients with different stages of liver disease.METHODS： Sixty two patients comprising of 12 inactive carriers, 30 chronic hepatitis patients, 13 patients with liver cirrhosis and 7 patients with hepatocellular carcinoma （HCC） were enrolled in the study. The HBV S, C and basal core promoter （BCP） regions were amplified and sequenced, and the clinical, serologic, phylogenetic and virologic characteristics were investigated.rESULTS： The study group consisted of 16 HBeAgpositive and 46 HBeAg-negative patients. Anti-HBepositive patients were older and had higher levels of ALT, ASL and bilirubin compared to HBeAg-positive patients. Phylogenetic analysis revealed that all patients were infected with genotype D （mostly ayw2）. The G1896A precore （PC） mutant was detected in 58.1% patients. HBeAg-negative patients showed a higher rate of PC mutant compared to HBeAg-positive patients （2,2 = 9.682, P = 0.003）. The majority of patients with HCC were HBeAg-negative and were infected with PC mutant variants. There was no significant difference in the occurrence of BCP mutation between the two groups, while the rate of BCP plus PC mutants was higher in HBeAg-negative patients （2,2 = 4.308, P = 0.04）. In the HBV S region, the genetic variability was low, and the marked substitution was P120T/S, with a rate of 9.7% （n = 6）.CONCLUSION： In conclusion, HBV/D is the predominant genotype in Iran, and the nucleotide variability in the BCP and PC regions may play a role in HBV disease outcome in HBeAg-negative patients.
