They have the advantages of providing quality power output with high voltage compatibility. The inverter is simulated in MATLAB/Simulink environment with the phase shifted SPWM control, implemented for the inverter. Besides this the paper proposed a methodology to control the AC inverter module structure of SPV configuration so as to obtain a good harmonic quality output power from SPV panels with improved THD of this supply. The methodology permits a high voltage output with a low total harmonic distortion without using any particular means for the same. It is capable of synthesizing a staircase output voltage reaching nearer to the sine wave output.","PeriodicalId":442235,"journal":{"name":"2017 Recent Developments in Control, Automation & Power Engineering (RDCAPE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125528101","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}

Wind energy, being a promising sector in renewable energy is now being integrated into the grid system and become a part of hybrid power system.

In the low speeds region, the phase currents are controlled by chopping. PI controller generates the reference current which is used for current chopping. Turn-on angle is fixed and turn-off angle is made to decrease with increase in speed. In the high speeds region, angle control mode is used where turn-on angles are generated using another PI controller instead of conventional lookup table approach. Turn-off angles are controlled by a generalized equation for both low and high-speed regions. This new control law is easy to implement, reduces complexity, saves time and efforts required for computation of angles as compared to look up table approach. Extensive simulations are carried out to compare the performance of motor with the conventional and proposed methods. It is found that the turn-on, turn-off angles and rms phase current obtained from both the methods vary with negligible difference. Simulation results are presented to demonstrate the dynamic response of the drive.","PeriodicalId":442235,"journal":{"name":"2017 Recent Developments in Control, Automation & Power Engineering (RDCAPE)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114715290","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}

In last step, every unknown node applies centroid method which uses impact of nearest anchor to get final coordinates.

The wide and abrupt change in load consumptions results in frequency and voltage variations alongwith the variations in the power of the tieline. In order to tackle this problem, AGC plays a very significant role in centralised operation of the power system with the aim to reduce the transient deviations and make steady state error to zero. To make the power business profitable, the modern complex power system is restructured or deregulated taking into account the increasing competition. In a deregulated power system, private sectors manage the generation, transmission and distribution of the electrical power as a result of which AGC has been imposed with more significant roles. In this work, a hydro-thermal reheat based two area deregulated power system is being modelled and then the performance of the conventional controllers is being compared with the intelligent fuzzy controllers for different transaction cases.","PeriodicalId":442235,"journal":{"name":"2017 Recent Developments in Control, Automation & Power Engineering (RDCAPE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128407512","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}

A number of these applications are based on the gathered data from flights; the data is usually acquired from the various sensors available on the aircraft. There are numerous senors among the electrical and electronics devices on an aircraft, most of which are essential for the proper functioning of the same. With the sensors being operational throughout the time of movement of the aircraft, a large amount of data is collected during each flight. Normally, most of the gathered data are stored on a storage device on the aircraft, and are analyzed and studied later off-site for research purposes focusing on improving airline operation and efficiently maintaining the same. In certain cases, when there is data transfer during the flight, it is between the aircraft and an air-traffic-control (ATC) tower, which serves as the base station. The aircraft equipped with all these sensors, which can gather and exchange data, form a framework of Internet of things (IoT). Detecting and avoiding any form of turbulence for an aircraft is vital; it adds to the safety of both passengers and aircraft while reducing the operating cost of the airline. Therefore, in this paper, we study techniques to detect and avoid Clear Air Turbulence (CAT), which is a specific type of turbulence, based on the IoT framework of aircraft. We propose algorithms that consider both direct and indirect communication between aircraft within a specific region. Using simulation results, we show that our proposed techniques of direct communication using the IoT framework is faster than conventional techniques involving radio communication via both single ATC tower and multiple ATC towers.","PeriodicalId":442235,"journal":{"name":"2017 Recent Developments in Control, Automation & Power Engineering (RDCAPE)","volume":"218 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124510675","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}
