Comparative analysis of FACTS controllers by tuning employing GA and PSO

Stability exploration has drawn more attention in contemporary research for huge interconnected power system. It is a complex frame to describe the behaviour of system, hence it can create an overhead for modern computer to analyse the power system stability. The preliminary design and optimization can be achieved by low order liner model. In this paper, the design problems of SMIB-GPSS and SMIB-MBPSS are considered to compare the performance of PSO and GA optimization algorithms. The performance of both optimization techniques are then compared further. Simulation results are presented to demonstrate the effectiveness of the proposed approach to improve the power system stability

A Novel Hybrid Approach for Stability Analysis of SMIB using GA and PSO

Stability exploration has drawn more attention in contemporary research for huge interconnected power system. It is a complex frame to describe the behaviour of system, hence it can create an overhead for modern computer to analyse the power system stability (PSS).The preliminary design and optimization can be achieved by low order liner model. This paper presents a hybrid approach for the stability analysis of single machine infinite bus system using generic power system stabilizer (GPSS) and proportional-integral-derivative

M40 GRADE SELF COMPACTED CONCRETE & COMPARISION IN BEHAVIOUR WITH M40 CONVENTIONAL CONCRETE

Self-compacting concrete (SCC) can get rid of the problem, because it is built to consolidate under its very own mass. Normal concrete was created by utilizing IS method and self-compacting concrete was created with a simple mix design suggested by Nan Su. SCC was created in 1988’s by Prof. Hagime Okamura in Japan. Conventional concrete has a tendency to present an issue with regard to sufficient consolidation in thin sections or regions of congested reinforcement, which results in a sizable amount of entrapped air voids and compromises the durability and strength from the concrete. SCC was among the special concrete in around the globe. This project handles the comparison of two various kinds of high strength concretes they're high strength conventional concrete and strength self-compacting concrete. An experimental and statistical study mechanical qualities, for example compressive strength, flexural strength and split tensile strength of self-compacting concrete (SCC) and also the corresponding qualities of conventional concrete (CC) were studied

Middle East - North Africa and the millennium development goals : implications for German development cooperation

          Closed-loop controlled combustion is a promising technique to improve the overall performance of internal combustion engines and Diesel engines in particular. In order for this technique to be implemented some form of feedback from the combustion process is required. The feedback signal is processed and from it combustionrelated parameters are computed. These parameters are then fed to a control process which drives a series of outputs (e.g. injection timing in Diesel engines) to control their values. This paper’s focus lies on the processing and computation that is needed on the feedback signal before this is ready to be fed to the control process as well as on the electronics necessary to support it. A number of feedback alternatives are briefly discussed and for one of them, the in-cylinder pressure sensor, the CA50 (crank angle in which the integrated heat release curve reaches its 50% value) and the IMEP (Indicated Mean Effective Pressure) are identified as two potential control variables. The hardware architecture of a system capable of calculating both of them on-line is proposed and necessary feasibility size and speed considerations are made by implementing critical blocks in VHDL targeting a flash-based Actel ProASIC3 automotive-grade FPGA

EEG Based Drowsiness Detection Using Mobile Device for Intelligent Vehicular System

Abstract—Drowsiness of driver is one of the causes for accidents. Here is proposal for drowsiness detection and alert using mobile phones. In this system driver has to wear USB EEG headset which is connected to mobile device. EEG will capture live brain signals and send to mobile device. Mobile device has a application installed in it which classifies these live signals and capture sleep /drowsiness related signals. Also, if mobile device finds a drowsiness signals it will activate alert in it this enables the driver to wake up or be alert. This proposal involves development of mobile application which classifies the live sleep signals from brain and activates the alert in it Index Terms—EEG, mobile device, sleep I

A Novel Tchnology for Harmonics and Unbalance Compensation in Electric Traction System Using Direct Power Control Method

Power quality problems in power systems have been improved due to nonlinear loads. To compensate these problems Direct Power Compensator was proposed in this paper. A Direct Power Compensator (DPC) is proposed in this paper to eliminate the harmonic currents, compensate power factor and voltage unbalance problems created by the nonlinear loads present in three phase systems. A DPC contains back to back converter by sharing the same dc link power and v/v transformer to provide a voltage balance in transmission line. Hysteresis harmonic current regulator is used to produce pulse for back to back converter. A controller maintains the dc-link voltage and compensates the power factor, harmonic currents. A comparative analysis for traction system with and without DPC was performed using MATLAB Simulink. Simulation results show the controller advantages and the applicability of the proposed method in railway systems
