It is my pleasure to get the opportunity of organizing the IEEE Power, Communication and information Technology Conference (PCITC-2015) at ITER, SOA University, Bhubaneswar, Odisha, India. The topic of this conference is timely as the host country and the state of Odisha are facing severe energy crisis, environmental hazards. Further new and emerging technologies in the area of Power, communication...
In this paper, a novel model predictive current control strategy is proposed for DSTATCOM to improve the power quality in distribution system. Unlike classical control schemes, the proposed method neither requires current PI controllers nor modulators at switching signal generation stage. The discrete-time model of the converter, filter and terminal voltage are used to predict the future behavior...
Mandrel provides the desired profile to the propeller in solid propulsion technology. Mandrel of known shape is inserted before casting process. Removal of centering ring, mandrel and bottom plate after curing is highly hazardous operation known as ‘decoring’. Friction overload in mandrel removal may cause explosion. Similarly bottom plate removal is highly risky since the bottom plate is in close...
This paper presents a scheme of remote updating based on any existing cellular network. The scheme is successfully implemented on 8 bit general purpose microcontroller for quick prototyping and incorporating the remote update feature even for small applications in a cost effective manner. Existing cellular network is used to avoid the cost and hassles of creating and maintaining a dedicated network...
In this Paper, we proposed a method for tracking multi moving bacteria and white blood cell (WBC) using Multi threading parallel (MTP) concept in a microscopic blood cell video. This method is based on continuously adaptive mean shift algorithm using color model which is designed to track multi moving bacteria using multi threading concept by comparing its mean in the successive frame in the video...
Recently, an efficient learning algorithm called extreme learning machine (ELM) has been proposed for training of single hidden layer feed forward neural networks (SLFNs). ELM has shown good generalization performances for many real applications with an extremely fast learning speed. This study proposes a computational efficient functional link artificial neural network (CEFLANN) trained with ELM...
In this paper an ensemble model is proposed for the recognition of Odia handwritten character. The ensemble model is constructed from four base classifiers: Support Vector Machine (SVM), Artificial Neural Network (ANN), C5.0 Decision Tree and Discriminant Analysis (DA). Gradient and curvature based features are extracted from the numerals and a combination of gradient and curvature based features...
In the area of wind energy conversion system (WECS), there has been a lot of research going on to improve the power extraction capability of the variable speed wind turbines. Permanent magnet synchronous generator (PMSG) based wind turbines have become more popular in this regard. In this paper detailed modeling of a direct-drive PMSG in the grid connected mode is presented. This paper compares the...
This paper proposes Volterra RLS (VRLS) adaptive filter for estimation of harmonic parameters and decaying DC component in presence of white Gaussian noise. VRLS shows good error convergence rate under high non-stationary and noisy conditions which is quite essential to estimate power quality disturbances. VRLS algorithm is an extension of Forgetting factor RLS (FFRLS) with the help of Volterra expansion...
A country's economic activity has a direct impact on the energy scenario of that country. The gap between the energy demand and the supply is continuously growing due to the increased dependency on the conventional energy sources which have limited resources. Continuous use of fossil fuels for generating energy has led to the effect of global warming. In India there is a huge scope for utilization...
In this paper, FPGA based all-on-chip digital controller is proposed which includes PI controller, +sequence detector, instantaneous power calculator, low-pass filters and hysteresis current controller. All these modules are configured on FPGA hardware resources aimed to mitigate harmonics and compensate reactive power in power distribution network. VHDL code for each module has been generated with...
Shunt active power filter, when used with non linear loads, provides an elegant solution to reactive power compensation as well as harmonic mitigation leading to improvement in power quality. The present study deals with fuzzy logic and neuro based controllers' viz. neural network control and neuro fuzzy control for shunt active power filter. Their superiority over PI type of controller is demonstrated...
This paper proposes a novel scheme to design a nonlinear optimal feedback controller for a STATCOM in order to enhance transient stability of a power system. The method of exact linearization with Brunovsky normal form is employed to formulate the nonlinear control law. The optimal gain matrix of the feedback controller is estimated applying Linear Quadratic Regulator (LQR) approach. The performance...
Due to the growth of internet and multimedia technology, there is a tremendous need for an efficient method of automatic video retrieval and storage process. Automatic annotation is one of the key solutions for the automatic retrieval or search of a particular scene based frames or a particular scene based videos from the huge video database. Video segmentation based on shot boundary detection (Cut...
