Abstract:

This paper discusses power quality improvement in a DFIG based WECS connected to a distribution system. A WECS is usually affected by issues such as high frequency oscillations, harmonics, transients, voltage sags, swells, voltage unbalance etc., These result in malfunction or damage to the electrical equipment in the system and lead to financial losses. So in order to mitigate the power quality events a UPQC device is employed which integrates series and shunt active filters that provide satisfactory compensation for power quality problems. The performance of UPQC is compared by using Fractional-Order PID controller and Adaptive Neuro Fuzzy Logic Controller. Modeling of DFIG and WECS systems is discussed with relevant equations. Design of UPQC and controllers is also discussed in detail. The proposed DFIG based WECS employing UPQC is simulated on MATLAB/ Simulink platform. The compensation capabilities of UPQC are assessed for both controllers for the proposed system and simulation results are presented.

Abstract:

This The direct torque control (DTC)operation merely depends on the selection of inverter switching sequences with look-up table thereby stator flux of the motor is not exactly equal to desired reference which causing high flux and torque ripple. This paper considers the effect of switching sequences of space vector modulation (SVM) and advanced space vector modulation (ASVM) on the performance of DTC. The SVM comprises unique pattern of switching sequences whereas ASVM is having two different patterns of switching sequences in the every sector which influences on the d-q axes flux distortion it shows significant effect on the ripple. The interpretation of ASVM versus SVM switching sequences required for the analysis of flux and torque ripple is shown with the case study of DTC. The flux ripple analysis shows that q-axis flux distortion merely effects on the torque ripple and d-axis flux distortion effects on flux ripple. The performance investigation of induction motor with DTC using SVM and proposed ASVM strategies are verified with simulations and experimental results. The experimental verification is conducted with Opal-RT real time digital simulator

Abstract:

In this paper load compensation using shunt active power filter (SAPF) is investigated balanced and unbalanced source voltages. PQ and d-q control algorithms are used for compensating the load current. The reference current given to the hysteresis controller is attained from PQ and d-q control methods. The exhibition of the proposed methods is assessed regarding reactive power, source voltage, and source currents, compensating currents and harmonics compensation as per IEEE-519 standard. To find out the suitability of the proposed control method, the paper is assessed under various source voltage conditions under balanced sinusoidal source voltage condition, all control techniques accumulated similar results. Under unbalanced sinusoidal source voltage condition, dq and PQ theories have demonstrated similar result, but in transient response PQ control has better performance. Simulation results are presented to validate the control methods.

Abstract:

Now a days Job satisfaction represents one of the most complex areas facing today’s managers when it comes to managing their employees. Many studies have demonstrated an unusually large impact on the job satisfaction on the motivation of workers, while the level of motivation has an impact on productivity, and hence also on performance of business organizations. Unfortunately, in our regionJob satisfaction has not still received the proper attention from neither scholars nor managers of various business organizations. The Goals of SBI Rayalaseema Division in Andhra Pradesh it is very difficult to improve the employee satisfaction levels and to increase the business also because of more competitors are available in society. Generally the employees perceptions are very different to one to others in Rayal aseema division, because of this area as very difficult to other state peoples more than ninety percent of the people are very illiterates. The present employees job satisfaction measured it is very difficult in the sense of every human being behavior, attitude, Economical status, environment changes, Relationships, societal status, culture, income levels, family impact, and thinking and decision are changes. This study mainly focused on employees level of satisfaction in the present job and employees spouse based satisfaction to the job satisfaction in the present job.

Abstract:

In this paper a natural habitat inspired metaheuristic Bird Swarm Optimization algorithm is implemented with improvisations made for the development of solution for the optimal allocations and optimal sizeprediction problem of Dispersed generation/ Distributed Generator in a radial power system distribution system in consideration of the drawbacks in the previous algorithms both in the context of convergence time and the optimal sizing with respect to the cost analysis for operation of the system with different number of DG’s installed in such a way that the optimal locations and sizes of DG’s installed is finalised with highest priority to the economical operation along with the immediate priority given to the network losses along with voltage deviations. To avoid the draw backs in previous optimisation algorithm regarding accuracy and run time. Along with the Cognitive component Weighted factor Bird Swarm optimisation (CWFBSO) algorithm a new concept is introduced called DG Size tuner Such that cost effective economical installation is possible as by the size tuner it is possible to compare the losses and voltage profile within the mean difference of the optimal sizes of final allocation determined by the main algorithm i.e., CWFBSO. Obtained results using CWFBSO in determining optimal locations and sizes of DG’s is capable showing good performance with less run time and convergence time and by using size tuner the optimal size selected economically with respect to less voltage deviation and minimal losses.

Abstract:

Due to extra effective control on emissions of carbon gas and economic benefits, Fuel cell EV is evolving into more favourite in the vehicle industry. Now- adays pollution is one of the important factors to reduce for better life. This paper introduces a neural network system based MPP tracking controller to track the maximum power from the01.260-kW proton exchange membrane fuel cell (PEMFC). The proposed neural network MPPT controller utilizes an adaptive-network based fuzzy inference system (ANFIS) algorithm to track the PEMFC's maximum power point. Switching frequency, voltage-gain required high for the propulsion of fuel cell EV. A 3-phase high voltage gain with interleaved technique based boost converter is intended for the fuel cell EV system to get the maximum voltage gain. The interleaving type technique minimizes ripple in input fuel cell current and the voltage stress on the used semiconductor devices. The analysis of the performance of the Fuel cell EV system with ANFIS controller used is compared with the radial basis FN controller in Simulink/MATLAB.

Abstract:

In this paper, we introduce, “an ensemble of Support Vector Machines (SVM) using Fuzzy-PAM” for network-based intrusion detection. First, the given set of features in a data set is partitioned into blocks or clusters based on correlation coefficient values between pairs of features or attributes. Then the data set is projected onto these feature set to obtain various data sets. SVM is applied on each data set. The given query pattern is also projected onto the feature set and the decision of each SVM is obtained. Weightage is given to each cluster, which is combined with decision of each SVM to obtain a final decision for classifying the given query. We shown the results of applying an ensemble of Support Vector Machines to 1999 KDD Cup data set.

Abstract:

The amount of text generated a day dramatically increases. Computers cannot easily process and perceive this enormous amount of mostly unstructured text. Therefore, to discover useful patterns, efficient and effective techniques and algorithms are required. Text mining is the process of extracting meaningful information from the text, which has received considerable attention in recent years. In this paper, we discuss several of the most basic tasks and techniques of text mining, including pre-processing, classification, and clustering. We also explain briefly text mining in the fields of biomedicine and health care.
