The islanding operation of DG usually occurs when the wind plant that is the source in the DG, still makes a section of the page distribution according to this section has been disconnected from the service program source. Distribution of the feeder islands with power DG are usually not required. In the proposed method, the q-axis current in the inverter is measured and the current controller is modeled...
Generally the output voltage of the inverters must be sinusoidal. However the waveforms of practical inverters are non sinusoidal and contain certain harmonics. For low and medium power applications, square wave or quasi square wave may be acceptable but for high power applications, low distorted sinusoidal waveforms are required. By increasing number of levels in inverter the output voltage have...
Multiplier is one of the major arithmetic operations carried out in DSP applications. Multiplier architecture is reconfigured so as to enhance their performance and thereby improving the efficiency of the applications. This Reconfigurable multiplier is adapted at run time to satisfy multiple precision requirements of DSP applications. Power consumption of the multipliers is reduced with the introduction...
Classifying the heterogeneous classes present in the hyper spectral image is one of the recent research issues in the field of remote sensing. The classification accuracy can be improved if and only if both the feature extraction and classifier selection are proper. As the classes present in the hyper spectral image are having different textures, textural classification is entertained. Wavelet based...
March tests have been found to be very effective for fault detection and diagnosis in memories. Effectiveness of a March test is usually decided by the number of faults that can be detected using the test. The more the number of fault models covered, the better the test. March tests with good fault coverage have been developed but the test power also plays an important role in deciding the effectiveness...
Reconfiguration of radial distribution system is the significant way of altering the flow of power through lines. This altered flow changes the real power losses, reactive power losses and voltage profiles. Privatized RDS need to operate profitably with minimum operational losses and power quality. Envisaging such a prospect, this paper focuses on the aspects of loss minimization and voltage enhancement...
