WAVELET TRANSFORM BASED DATA COMPRESSION FOR REAL TIME POWER QUALITY DISTURBANCES  Suresh K. Gawre1* , N. P. Patidar2 and R. K. Nema3  1,2,3Department of Electrical Engineering, Maulana Azad National Institute of Technology, Bhopal - 3, India   ABSTRACT  Memory space for storing the power quality signal are major concern due to penetration of novel power sources and highly sensitive loads in modern power system. Wavelet based data compression approach is presented in this paper for the automatic data reduction and signal analysis. Real time data of power quality signals have been processed with IEEE Power quality wave data, to deal with practical implementation. The method proposed, which can be processed in real-time, showing the potential in data reduction and accurate characterization of voltage power quality signal in power systems .  KEYWORDS  Power quality signals, Data compression, Wavelet analysis, Real time monitoring, Wavelet ...

HARMONICS MITIGATION OF P&O MPPT BASED SOLAR POWERED NEUTRAL POINT CLAMPED MULTILEVEL INVERTER  Nikhil Kumar1 ,Suresh Gawre2,Deepak Verma3 and Vivek Kumar4  1, 2,3,4Department of Electrical Engineering, MANIT, Bhopal, India  ABSTRACT  To supplement the power shortages, renewable energy sources are a promising source among the existing resources of energy out of which solar PV (photo voltaic) is most popular due to its significant advantages. Controlling the output of solar PV system and harmonics at the load end are key aspects. The main theme of this paper is to control output of solar PV system with MPPT (maximum power point tracking) and reduction of harmonics at the load end.In this paper, commercial solar arrays of 1.2 kW along with P&O (perturb and observe) MPPT to track maximum power has been interfaced with neutral point clamped multilevel inverter.Simulation has been done for different level with the aim to reduce THD (total harmon...

AN ANN BASED MOBILE ROBOT CONTROL THROUGH VOICE COMMAND RECOGNITION USING NEPALI LANGUAGE Neerparaj Rai1 and Bijay Rai2  1Department of Electrical and Electronics Engineering, Sikkim Manipal University, Sikkim, India 2Department of Electrical and Electronics Engineering, Sikkim Manipal University, Sikkim, India  ABSTRACT  The analog speech signal can be used for interacting with machines, computers or robots. In this case, speech algorithm is capable to recognize the voice commands that are given as inputs to a mobile robot through wireless XBee modules. It is actually a form of Word Recognition. In this presented paper, a voice command recognition system is going to be developed by using Artificial Neural Network (ANN). The Commands that used here are all in Nepali Languages (used in North East India). LPC analyzes the speech signal by estimating the formants, removing their effects from the speech signal. The process of removing the formants is called in...

DATAFLOW IN MODERN INDUSTRIAL AUTOMATION SYSTEMS. THEORY AND PRACTICE  Marcin Bajer1 1 ABB Corporate Research Kraków, Poland  ABSTRACT  The goal of this publication is to provide brief description of industrial communication protocols. This paper shows how data flow can be realized in modern manufacturing facilities and how to integrate multiple data sources (sensors, actuators and controllers) into one heterogonous system. In order to illustrate the problem a model of multi tank water control system has been developed. In addition the paper presents approach to access production data by Android based devices.  KEYWORDS  Fieldbus, OPC, Profibus, Profinet, Android, XML RPC  Original Source URL :   http://airccse.com/ijaceee/papers/2414ijaceee01.pdf http://airccse.com/ijaceee/current2014.html
