The control structure for a variable speed wind turbine is explained with a maximum power extraction. The wind generating system consists of variable speed wind turbine (VSWT) with three types of wind speed data (i) Step wind speed (ii) Staircase wind speed and (iii) random wind speed, Permanent magnet synchronous generator, uncontrolled rectifier, voltage source inverter and Bidirectional DC-DC converter along with a Battery storage system has been presented. The control strategy is so adapted to supply the load with a constant voltage and frequency under load change and wind speed change. The control strategy involves control of the bi-directional DC-DC converter of a battery system in order to maintain the constant DC-link voltage due to the variation in wind speed to the constant DC-link voltage. The control strategy used for Inverter control consists of a DC-link control, voltage and current control which is used to control the load voltage and frequency under load variation. The wind energy system is modelled in MATLAB/ SIMULINK.","PeriodicalId":131311,"journal":{"name":"2018 Recent Advances on Engineering, Technology and Computational Sciences (RAETCS)","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123706130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The shape of radiating element is Isosceles- Triangle. Fractal concept is used to design the isosceles triangle shaped patch antenna and the required Isosceles Triangle Fractal Antenna (ITF- Antenna) is designed. This antenna uses the concept of Von Koch’s snowflake. Koch snowflake concept is based on generating L Euclidian segment which is divided into three segments. The antenna is developed using two iterations geometry. Simulations were carried out using commercially available method of moment based IE3D software. The proposed design is also verified using another methodology HFSS (High Frequency Structure Simulator) based of finite element method. The antenna resonates at 12.31 GHz, 13.18 GHz, 15.21 GHz and 19.7 GHz. Hence, Ku-band [12– 18 GHz] and K-band [18– 27 GHz] is the frequency of operating band under consideration. Also the gain of proposed antenna 5.1613 dB at frequency of 15.21 GHz is achieved. The comparison of return loss versus frequency plot of proposed antenna using both the simulation verified the results.","PeriodicalId":131311,"journal":{"name":"2018 Recent Advances on Engineering, Technology and Computational Sciences (RAETCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121763399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design of networking layer based on various routing and transmission protocols suffer from the attack problem. The generation of insider attacker not only damages the network structure, it also modifies the routing path and hacking the packet information. The integration of IoT with the WSN alleviates the issues due to the insider attackers. This paper proposes the novel shape model based on Localized Geometric Voronoi Hexagon (LGVH) algorithm and the secure communication using key management procedures. The consecutive process of key establishment, update and revocation provide the necessary resistance to the insider attackers. The LGVH algorithm provides the necessary location information regarding the Sensor Nodes (SN) predicts the coverage area for the dynamic environment. This paper expands the customizable WSN simulator tool based on NS2 simulator provides the detailed coverage area. The comparative analysis between the proposed model with the existing methods regarding the various parameters confirm the effectiveness and contributions to the real-time IoT applications.","PeriodicalId":131311,"journal":{"name":"2018 Recent Advances on Engineering, Technology and Computational Sciences (RAETCS)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115066535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Induction motors are mostly used in every sector that may be industrial or commercial due to its easy handling nature. For the control of the induction motor variable voltage and variable frequency is supplied by the voltage source inverter (VSI). Where the switching pulse can be generated by using different pulse width modulation (PWM) techniques. The PWM techniques those are discussed in this paper are sinusoidal based Pulse Width Modulation (SPWM) and Space Vector based Pulse Width Modulation (SVPWM). The triggering pulse in the SPWM method is generated by comparing the sinusoidal wave with the triangular wave. Whereas in case of the SVPWM strategy the pulse is generated by taking the revolving rotating vector as the reference vector instead of the three-phase sine wave as in case of SPWM strategy. SVPWM method is the advance computational PWM technique. This paper presents the complete analysis of three phase VSI fed induction motor using these two PWM techniques on the basis of the total harmonic distortion (THD) in current, transient behaviour and switching losses for modulation range of 0 to 1. MATLAB/SIMULINK programming has been utilized for the execution.","PeriodicalId":131311,"journal":{"name":"2018 Recent Advances on Engineering, Technology and Computational Sciences (RAETCS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124965287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
