Abstract

This paper proposes a nine level cascaded multilevel inverter based on the flip flops and logic gates. Generally multilevel inverter is used to achieve the high power by using a series of power semiconductor switches with the several dc voltage sources which is used to perform the power conversion. In this paper the flip flop based CMLI is compared with the conventional CMLI. The flip flops and logic gates are used to create logic equation for the each switch of the CMLI by using the switching states. This proposed topology is mainly used to reduce the total harmonic distortion and also increase the performance of the system.

Abstract

Induction motor characteristics are complex to study, so in order to simplify its complexity modelling of induction motor will be useful. Proposed paper dealt with the simulation of induction motor based on the mathematical expression using the graphical user interface software. Laboratory Virtual Instrument Engineering Workbench (LabVIEW) software is used for modelling the induction motor and helps in analyzing the performance characteristics of a machine. After the invention of special electrical machine the research in induction motor starts to decreases but it is the widely used motor in industries. The study about induction motor characteristics became complex after the incorporation of power electronic switches such as thyristor, diodes, GTO, and MOSFET. In duction motor characteristics can be studied and modelled with the help of numerous software’s such as Finite Element Analysis and Laboratory Virtual Instrument Engineering Workbench.

Abstract

In this paper, we investigate the performance of Decode and Forward (DF) in multiple relay networks. We consider a cooperative diversity system where a source sends information to the destination with the aid of multi relay working in DF relaying protocol and investigate the Optimal Power Allocation (OPA) at both the source and the relay nodes. By taking advantage of the moment generating function (MGF), a closed form expression for the symbol error rate (SER) and signal to noise ratio (SNR) for both, M-Phase Shift Keying (MPSK) and M-Quadrature Amplitude Modulation (MQAM) signals has been derived to illustrate the asymptotic performance of the DF system where the approximation SER is tight at high SNR. Results show that the proposed system, based on SER lower bound is tight to the theoretical SER upper bound, and the suggested OPA outperforms the equal power allocation (EPA) and at different number of relays.

Abstract

To deploy the enormous hardware resources available in Multi Processor Systems-on-Chip (MPSoC) efficiently, rapidly and accurately, methods of Design Space Exploration (DSE) are needed to evaluate the different design alternatives. In this paper, we present a framework that makes fast simulation and performance evaluation of MPSoC possible early in the design flow, thus reducing the time-to-market. In this framework and within the Transaction Level Modeling (TLM) approach, we present a new definition of ISS level by introducing two complementary modeling sublevels ISST and ISSPT. This later, that we illustrate an arbiter modeling approach that allows a high performance MPSoC communication. A round-robin method is chosen because it is simple, minimizes the communication latency and has an accepted speed-up. Two applications are tested and used to validate our platform: Game of life and JPEG Encoder. The performance of the proposed approach has been analyzed in our platform MPSoC based on multi-MicroBlaze. Simulation results show with ISSPT sublevels gives a high simulation speedup factor of up to 32 with a negligible performance estimation error margin.

Abstract

Nowadays, with the growing needs of the consumers there is a huge demand for the electric power but the fuel reserves are also depleting at the same pace. So, this has created the need to depend up on the renewable energy resources to meet the required power demand.  Since the power generated through renewable resources is eco friendly in nature and distributed, this is an added advantage. Of all the renewable energy resources solar and wind plays the most crucial part in the power generation because of their wide spread availability. But the wind energy is volatile and intermittent by nature, due to this interconnecting the power generated to grid becomes a hectic task. So in this paper a wind power forecasting model with the help of artificial neural networks (ANN) is developed so that the wind power can be forecasted well in progress, which helps in maintaining and operating grid interconnection and also scheduling of units. The developed model is based on the non-linear auto regressive with exogenous input (narx) tool which trains the ANN for the time series. The input parameters taken into consideration are wind speed, temperature, pressure, air density and the output parameter is generated power. The required data is collected from the Energy Department of KLUniversity, Andhra Pradesh which consists of 720 hours data from that 672 hours data is used for training and 48 hours data is used for prediction. Mean square error and root mean square error are calculated from the predicted and known results.
