This paper describes the effectiveness of using dynamic voltage restorer (DVR) in order to mitigate voltage sags and swells in low voltage distribution systems. A dynamic voltage restorer based on the dqo algorithm is discussed. The proposed control scheme is very effective to detect any disturbance in low voltage distribution systems. Simulation results using Matlab/Simulink are presented to v...

Voltage Sag is one of the Power Quality problem and it become severe to industrial customers. Voltage sag causes miss operation to several sensitive equipments. This problem can be mitigating with the Dynamic Voltage Restorer. DVR is a solid state device which is connected in series between the source and load voltages. In this Dynamic Voltage Restorer is implemented using Capacitor Clamped Mul...

Three A1 CMS sources (ICMB 94555, ICMB 98222 and 96666) were crossed with fifteen potential restorer lines in line × tester fashion to elucidate the information on combining ability for seed yield its component traits. A total of forty five crosses evaluated eleven different quantitative Among three used study, 96666 exhibited significant gca effects most characters studied found be good combin...

Mitochondrial DNA preparations were made from 31 maize lines carrying different sources of cytoplasm in the same nuclear genetic background. The DNAs were analyzed by agarose gel electrophoresis. A number of discrete low molecular weight bands were present in all lines. However, only four different DNA banding patterns were observed. These were correlated with the N, T, S and C cytoplasms defin...
