Shunt Active Power Filters (SAPF) are a common solution for mitigation of current harmonics in the system. This paper presents evaluation of fixed-band hysteresis current controller based two-level converter used as a SAPF. Hysteresis current control scheme is preferable because of ease of implementation, robustness against parameter variations and fast dynamic response. Because of the inherent advantages associated, this paper emphasizes to extend the same control strategy to multilevel converters as well. This paper presents advanced multiband hysteresis modulation scheme for three-level Neutral Point Clamped (NPC) converter based SAPF application. Detailed analysis of the proposed control scheme is presented and the claimed performance of both SAPF configurations are validated from results obtained by carrying out extensive simulations in MATLAB/Simulink environment.","PeriodicalId":442235,"journal":{"name":"2017 Recent Developments in Control, Automation & Power Engineering (RDCAPE)","volume":"1 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":"128691967","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}

Based on appliance level energy consumption data optimum energy utilisation can be obtained by formulating load scheduling strategies. Power consumption of an appliance load is smooth and follows a certain pattern, this motivates the use of graph based signal processing (GSP) for NALM. In the presented work we propose a different NALM method by incorporating on GSP, by representing active power dataset on a graph. Proposed regularization method is applied for maximizing the smoothness of the graph signal, which allow us to perform energy disaggregation in simpler manner. Proposed method is evaluated on publically available iAWE dataset.","PeriodicalId":442235,"journal":{"name":"2017 Recent Developments in Control, Automation & Power Engineering (RDCAPE)","volume":"1 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":"128629430","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 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}

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}

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}

The safety system employed here uses image processing for pedestrian identification and brake by wire method of automatic braking. In this paper, the analysis is done by preparing an experimental setup, simulating and obtaining the results. The methodology of the experiment is that when a pedestrian is detected in the camera, the warning light glows and when the collision is imminent, the vehicle automatically brakes.
