Abstract

In this paper, we propose an energy management system with hybrid solar and wind renewable energy system (RES) with Multilevel inverter to give a lossless power to load. This system continuously receives the battery storage and power consumption after it checks the these value with default value if power consumption is exceeds default value means it turn off  the loads. We are assigns the priority to the loads in order to overcome the user inconvenient. To increase PV module output MPPT is used. The existing system uses only boost converter, in our paper boost converter is combined with buck converter used because the PV module can produce high voltage  than DC-bus voltage. Buck converter used to step down purpose. In this  system  on-line configuration check and buck-boost mode transition will be presented. Experimental results measured from three-string MPPTs with EMS the maximum power level of 10 kW are used to verify the analysis and discussion with hybrid cascaded multilevel inverter.DOI:http://dx.doi.org/10.11591/ijece.v4i1.4529

Abstract

The design of a novel rectangular dielectric resonator antenna (DRA) for multi-band application has been presented in this paper. The presented antenna has been composed of very low cost and relatively low dielectric constant substrate materials while three-segment thin dielectrics with different sizes have been used and separated by two metal plates in order to set the four different frequency bands. The proposed quad-band antenna operates at 2.4/3.5/5.2 & 5.8 GHz. The radiation pattern, gain and VSWR of this antenna show very good operation for this antenna in all frequency bands. The first method based on finite element method (FEM) and the second one based on finite integral technique (FIT) have been used to analyze antenna structure, and subsequently the Genetic Algorithm (GA) has been applied by using HFSS simulator to obtain the optimized parameters.DOI:http://dx.doi.org/10.11591/ijece.v4i1.4576

Abstract

The majority of research is about the detection of broken bar fault in three-phase induction motor at high slip. Thus, it becomes very interesting and demanding to detect faults in case of low slip range. In this study, a novel investigation of broken bar faults using instantaneous power is presented. The method is based on calculations and frequency analysis of partial and total instantaneous power under low slip range. The used model of squirrel cage induction machine takes into account the geometry and winding layout. This model will be used to analyze the impact of broken bar on instantaneous power spectrum. The proposed ideas in this paper are verified experimentally. The results show that broken bar fault can be more reliably detected under low slip range when using a large frequency area of both partial and total instantaneous power spectrums.DOI:http://dx.doi.org/10.11591/ijece.v4i1.4611

Abstract

A software product line consists of a family of software systems. Most of quality attributes are defined for single systems. When we are facing a family of products instead of a single system, some aspects of architecture evaluation, such as cost, time, and reusability of available assets, become more highlighted. In this paper a new quality attribute for software product line, which we called it extractability, is introduced. Also extractability measuring method and relationship between extractability with some quality attributes is presented. At the end, Extractability Effectiveness on Software Product Line is evaluated in practice.DOI:http://dx.doi.org/10.11591/ijece.v4i1.4106

Abstract

In this paper, an improved robust model predictive controller (RMPC) is proposed based on model reference adaptive system (MRAS). In this algorithm, using the MRAS a combinational RMPC controller for three degree freedom satellite is designed such that the effect of moment of inertia uncertainty and external disturbance is compensated on the stability and performance of closed loop system. Control law is a state feedback which its gain is obtained by solving a convex optimization problem subject to several linear matrix inequalities (LMIs). To avoid the actuators saturation an input constraint is incorporated as LMI in the mentioned optimization problem. In addition to, using the MRAS system the effect of input disturbance is rejected on the system.The advantages of this algorithm are needless to exact information from system’s model, robustness against model uncertainties and external disturbance. Results from the simulation of the system with the proposed algorithm are presented and compared to generalized incremental model predictive control (GIPC). The results show that the suggestive controller is more robust than the GIPC method.DOI:http://dx.doi.org/10.11591/ijece.v4i1.4961

Abstract

To reduce the high harmonic components at the main power supply current and to improve the input voltage distortion for matrix converter, design of input filters characteristics for matrix converter system is very important. Also, the input filter can be applied to the near unity power factor operation at the input side. It can be used to improve the power quality of the input current. This paper represents a direct space vector modulation (SVM) method and introduces switching patterns for SVM method and then design of input filter to compensate the power factor is analyzed. Simulation results with inductive load (RL) and Permanent-magnet synchronous motor (PMSM) are shown to validate the effectiveness of the proposed method.DOI:http://dx.doi.org/10.11591/ijece.v4i1.4813

Abstract

This paper presents a novel design of a I- slotted patch antenna with compact nature and the study of various antenna parameters. The antenna is fed by inset feeding technique. The proposed patch antenna is designed and simulated on IE3D simulation software. The main aim of proposed work is to obtain a large bandwidth antenna with compact  size. The proposed microstrip antenna has a wide bandwidth covering the range from 1.444-2.393 GHz. By using simple Inset feed technique & by introducing I-slotted wide bandwidth of 49.46%, High Gain  5dBi  & good radiation efficiency of about 99% has been achieved.DOI:http://dx.doi.org/10.11591/ijece.v4i1.4594
