A Novel Controller for Inverters to Improve the Frequency Response of Micro Grid under Transient Conditions
M. Nanda Kumar Reddy, R. Narendra Rao
DOI: 10.17148/IJIREEICE.2016.41101
Abstract: The present scenario is towards shifting centralised power generation (central grid) to distributed generation (micro grid) with smaller sources of capacity. The isolated micro grid is connected to main grid with inverters at the front end for efficient exchange of power sharing; power exchange among distributed generation (DG) sources in an isolated micro grid is possible with droop characteristics as per their capacity. The stability and operation aspects of converter-dominated microgrids (MGs), however, are faced by many challenges. Important among these, are the absence of physical inertia, comparable size of power converters, mutual interactions among generators islanding detection delays and large sudden disturbances associated with transition to islanded mode, grid restoration, and load power changes. Sources in the MGs use droop control to share power according to their capacity without any form of communication. This paper proposes a novel controller for inverters in DG for improving transient frequency response of the micro grid under consideration of large disturbances with considerable frequency deviations to validate the effectiveness of the proposed P-F droop controller simulation is carried out on MATLAB Simulink platform.

Transfer Function Model Based Analysis of Permanent Magnet Synchronous Motor with Controllers
Y.V.P. Karteek, Dr. N. Prema Kumar
DOI: 10.17148/IJIREEICE.2016.41102
Abstract: Permanent Magnet Synchronous Machine (PMSM) drives have been increasingly applied in a wide variety of industrial and mechatronics applications over other conventional drives. The reason comes from the advantages of PMSM: high power density and efficiency, high torque to inertia ratio, and high reliability. In this paper, the study and the design analysis of controllers and controller methods for PMSM is given. An existing BLDC motor for an electric forklift benchmarks the expected performances of the PMSM design. In the first part there is account working principle and design of PMSM. Mathematic model of PMSM is used for calculation for behavior of PMSM. Later, the mathematical modeling of PMSM has been done through Transfer Function approach. Later, obtained transfer function was subjected to controller approach which determines the performance of the PMSM. Initially, the Zeiglers-Nicholas PID controller method is used to determine the PMSM performance by two different sub controllers of ZN say, ZN-PI and ZN-PID Controllers. Next to this method, Pole Placement Technique is used for comparison of ZN-PI, PID. Characteristic Ratio Assignment (CRA) method is also used to determine the PMSM performance which was the main area of interest. This CRA method is solved with specimen problems initially and then solved for the transfer function that is derived in earlier stage. To know the performance of PMSM, CRA-PID controller is chosen in this thesis work. This method is mainly based on Pole Placement Technique. And it works on transient response of the transfer function. For the extension to this work, Fuzzy PI Logic Controller is also used to compare with CRA method. Finally, the specimen simulation problem is also performed in order to determine the speed, torque and current characteristics.

Palette Embedded Images by Steganographic Technique
Dr. KP. Ramesh Babu, Mr. Taffera Mekonen, Mr P. Prasanna Kumar
DOI: 10.17148/IJIREEICE.2016.41103
Abstract: In this paper presents, a new steganographic technique for embedding messages in palette-based images, such as GIF files. Steganography is a method of secret communication wherein the very existence of communication is hidden. During the last few decades there has been a tremendous development in digital image steganography the new technique embeds one message bit into one pixel (its pointer to the palette). The pixels for message embedding are chosen randomly using a pseudo-random number generator seeded with a secret key. For each pixel at which one message bit is to be embedded, the palette is searched for closest colors. The closest color with the same parity as the message bit is then used instead original color. it has the advantage that both the overall change due to message embedding and the maximal change in colors of pixels is smaller than in methods that perturb the least significant bit of indices to a luminance-sorted palette, such as EZ Stego [1]. Indeed, numerical experiments indicate that the new technique introduces approximately four times less distortion to the carrier image than EZ Stego. The maximal color change is 4 to 5 times smaller for the new technique than that of EZ Stego. This method introduces less distortion to the carrier image will generally cause changes that are more difficult to detect, and will therefore provide more security.

DOI: 10.17148/IJIREEICE.2016.41104
Abstract: Now a day, because of the technological developments in power electronics industry, it is easy and more secure to operate the power system to enhance the performance. The power electronic based controllers are used to improve the power transfer capability, voltage control and the system active power losses, simply known as Flexible AC Transmission System (FACTS) Controllers. Based on the type of connection of the voltage source converters in a given system, it has been proved that, multi-line controllers are more powerful than that of the single line controllers. In this paper, detailed power injection model of Generalized Unified Power Flow Controller (GUPFC) is presented. The effect of this device on system parameters is analyzed by incorporating this device in NR load flow. The proposed methodology is tested on standard 9-bus and IEEE-23 bus test systems with supporting numerical and graphical results.

Enhancement of Distributed Power Flow Controller during Series Converter Failures
V. Sudheer Kumar, Raja Reddy. Duvvuru
DOI: 10.17148/IJIREEICE.2016.41105
Abstract: The Distributed Power Flow Controller (DPFC) is a new device within the FACTS family. It is emerged from the UPFC and has relatively low cost and a high reliability. The DPFC consists of two types of converters that are in shunt and series connected to grids. The common dc link between the shunt and the series converters is eliminated. The active power exchange between the shunt and series converters that is through the common dc link in the UPFC, is now though the transmission line at the 3rd harmonic frequency. The redundancy of the series converters provides the high reliability of the system. In this paper, the DPFC behaviour during the failure of a single series converter unit is considered. A control scheme to improve the DPFC performance during the failure is proposed. The principle of the control is based on the facts that, the failure of single series converter will lead to unsymmetrical current at the fundamental frequency. By controlling the negative and zero sequence current to zero, the failure of the series converter is compensated. In this paper, the principle of the DPFC are firstly introduced, and followed by the behavior of the DPFC during the failure of a single series converter. The design of the control scheme and corresponding simulation are presented.Therefore, the cost of the DPFC system is lesser than the UPFC. The simulation is done using Matlab/Simulink software which is implemented on simple four bus system to expose the device control features and their impact on increasing capability of power transfer.

Comparative Analysis of Type-1 and Type-2 Fuzzy Controllers with different Membership Functions for CSTR
P. Durga Prasada Rao, M. Srinivas, V. Nagaprudhvi Raj
DOI: 10.17148/IJIREEICE.2016.41107
Abstract: All the real systems exhibits non-linear nature, conventional controllers are not always able to provide good and accurate results. Fuzzy Logic Control is used to control non linear processes and obtain better response. Type 1 Fuzzy control is traditional fuzzy controller which is prone to uncertainties. Type 2 Fuzzy control generalizes type 1 fuzzy control. Type 2 fuzzy set incorporates instances of uncertainties in its membership function. Membership Function plays very crucial role in the Fuzzification process. The values of Membership Function must be defined precisely. Membership functions allow us to graphically represent a fuzzy set. The continuous stirred tank reactor (CSTR) is a non linear process and the concentration maintenance is very difficult. So it is prone to uncertainties more as a result, type 2 fuzzy controller must be used. In this paper we perform comparative analysis on different membership functions used in type 1 and type 2 fuzzy controllers. The application used for the comparative analysis is CSTR and the software used is MATLAB/SIMULINK.

Geetanjali Kalamb, Prof. A.G. Gaikwad
DOI: 10.17148/IJIREEICE.2016.41109
Abstract: This paper presents design of monopole band notched ultra wideband antenna. A coupling strip gap introduced in the square patch helps to notch certain frequency bands. This is a compact, low power ultra wide band (UWB) antenna which mitigates the saturation of spectrum. Its low power characteristic make it invisible for the radio systems sharing the same spectrum hence minimizes interference due to other licensed bands. This proposed band notched UWB antenna is used for several frequency bands such as Wi-Max(3.3 GHz to 3.6 GHz), WLAN (5.15 GHz to 5.35 GHz and 5.725 GHz to 5.825 GHz) and HIPERLAN/ 2( 5.15 to 5.35 GHz and 5.47GHz to 5.725 GHz).

Abstract: Secure and Fast Sub-Graph search is system which is used over outsourced cloud database for search graph which are same to a queried by the client or user. Graph Data is increasing day by day, so database outsourcing is an solution to increasing graph database to the database owner. But, Cloud Database and query service Authority providers not trust or may be involved in attacks. In this paper, we propose authentication process techniques using Attribute base encryption for checking user credential either trusted or untrusted user to prevent tempering with cloud database. We propose a Fast sub graph retrieval technique using apriori algorithm .we also implement the Data deduplication to save the space on cloud using hashing generating function to avoid same data copy over cloud database. We also propose file ownership generation technique for owner of data. Our compressive results verify the effectiveness and efficiency of our proposed techniques.

Abstract: In this paper, a solution about secure provenance transmission for streaming data which is introduced based on Raspberry Pi processor, is presented. The embedded system, video capture, and video monitor are introduced. Video 4 Linux is used to get the camera video data, which is transferred to the Web Server, and the data is displayed on the client browser. The main aim of this paper is to design a system that has a USB camera, which continuously captures videos of the people then processes the captured videos via USB host to the Raspberry Pi to display it on the display device unit, and the parallel connection of Ethernet module, web page is created on the remote PC using HTTP protocol because HTTP protocol provides secure data transmission. And for more security we are creating some IP address to view the live streaming data on remote PC and when the person appears in front of camera the processor collects the information and stores temporarily in the database to check or recognize, is this person the right person to use or not. Compared with video capture system based on digital signal processor(DSP), this system has the advantage of fewer modules, lower cost, higher intelligence, higher system stability, and higher security. The design of system presented in this paper will integrate ARM11, USB cam, Remote PC, Display Monitoring unit, and Ethernet. The entire process proves continuous, and a surveillance secured system.

Study & Implementation of Audio Watermarking using DWT-SVD-Firefly Algorithm: A Review
Er. Harmanpreet Singh, Er. Shagun Sharma
DOI: 10.17148/IJIREEICE.2016.41120
Abstract: This paper investigates the development of digital audio watermarking in addressing issues such as
its own advantages and disadvantages. The main aim of this thesis was to develop a new watermarking algorithm within an existing discrete wavelet Transform (DWT) and singular value decomposition (SVD) framework. This resulted in the development of a combination of DWT-SVD-Firefly (Firefly algorithm) watermarking algorithm. In this new implementation, the embedding depth was generated dynamically thereby rendering it more difficult for an attacker to remove, and watermark information was embedded by manipulation of the spectral components in the spatial domain thereby reducing any audible distortion. Further improvements were attained when the embedding criteria was based on bin location comparison instead of magnitude, thereby rendering it more robust against those attacks that interfere with the spectral magnitudes. The further aim of this thesis is to analyze the algorithm from a different perspective.

Abstract: This paper presents multitier biometrics using watermarking algorithms with two levels of security for simultaneously verifying on individual and protecting the biometric template. The fingerprint as unique biometric templates is used as a watermark for digitally signing images linked to the watermark. The image can be used directly for verification and the watermark fingerprint data is used to cross authenticate the individual any attempt to tamper the image will consequently change the watermark embedded within it and create a discord between the embedded watermark and biometric data obtained on verification.

Review Paper: Advantages and Limitations of Li-Fi over Wi-Fi and iBeacon Technologies
Deepika D Pai
DOI: 10.17148/IJIREEICE.2016.41122
Abstract: Li-Fi can be thought of as a light-based Wi-Fi. That is, it uses light instead of radio waves to transmit information. And instead of Wi-Fi modems, Li-Fi would use transceiver-fitted LED lamps that can light a room as well as transmit and receive information. Light is inherently safe and can be used in places where radio frequency communication is often deemed problematic, such as in aircraft cabins or hospitals. So visible light communication not only has the potential to solve the problem of lack of spectrum space, but can also enable novel application. The visible light spectrum is unused; it's not regulated, and can be used for communication at very high speeds. This paper compares the Li-Fi technology with Wi-Fi and iBeacon technologies.

A Novel Study on Uplink and Downlink Transceivers for LTE System: A Review
Geeta Rani, Er. Vikas Chawla
DOI: 10.17148/IJIREEICE.2016.41123
Abstract: LTE is the latest cellular network technology to offer universal mobile and wireless access to smart-phones and tablets. The system provides a review on uplink and downlink strategy in LTE system. There are basically two modulation techniques that are used in LTE system mainly OFDMA and SC-OFDMA. OFDMA is used in downlink and SC-OFDMA is used in uplink. The major disadvantage of OFDMA is the high PAPR (peak to average power ratio) that causes more power consumption. That is why it cannot be used in uplink because UL is power limited link. The main objective of this paper is to design optimum physical layer architecture of a high data rate LTE uplink and downlink transceiver using SC–FDMA multiple access scheme to provide lesser PAPR value and avoiding packet loss by Interleaving. All simulations will be done in MATLAB tool.

One of the most interested application in a broad area is the induction motor control. The aim of this paper is to implement a new control system for driving three-phase induction motor .this control system aim to enhance the performance of induction motor as well as improving the power factor at both input sides and output sides with remarkable reduction in total harmonics distortion of the supply current .the system consists of dual boost converter connected in parallel with uncontrolled rectifier for producing a dc voltage .this approach depends on the power-sharing optimization strategy to enhance the current quality, which leads to keeping power factor at the input side near unity with minimization of the total harmonics distortion (THD) of supply current . The dc voltage produced from this structure is delivered to a three-phase inverter which is controlled by space vector pulse width modulation (SVPWM) for driving three phase induction motor. The proposed system has been implemented using MATLAB/Simulink software package. The simulation results show promising improvement of the induction motor performance.

Abstract: This paper presents detailed study of various color constancy techniques. Color constancy is the ability to approximation of the color of the light sources. Unusual illuminates may impact the appearance of an image as compared to the image taken under canonical light source. Face is one of the most popular biometric modalities. This paper represents in detail about the color constancy of 2D-3D face and objects using color consistency and the brightness of the images. These results suggest that color constancy has a positive impact on face recognition.

Abstract: PPG signal is an effective method to assess the cardiovascular parameters like heart rate, blood oxygen saturation, blood pressure and respiration rate. Motion and other artifacts introduced during acquisition of PPG, limits the accuracy in estimation of clinical parameters. In this paper, we present wavelet based feature extraction and motion artifacts removal methodology to overcome the issues of heart and respiratory parameter estimation. In the proposed algorithm, point of interest coefficients are ascertained for every wavelet sub-band grid, producing a changed wavelet sub-band network. This makes the exhibited algorithm more efficient. Every information set comprises of deliberately made conceivable MA noises, viz., vertical, flat, waving, and squeezing MAs with distinctive breathing examples. The technique is connected on the recordings accessible of Physionet dataset. The measurable and classification investigation, performed to test the viability of the introduced new algorithm, uncovered a decent acknowledgment for inferred respiratory signal, when contrasted and the initially recorded respiratory signals utilizing traditional strategy. To perform the classification of the dataset, neural network is used. The proposed strategy obviously outperforms the customary heart rate detection system in the vicinity of MA. The results of proposed system show the approximate 99.9% of sensitivity and 99.7% of specificity.

Abstract: Synchronization is an essential task for any digital communication system. Without a proper accurate synchronization method, it is not possible to reliably receive the transmitted data. Synchronization is the first and most important task that must be performed at the receiver. So, whole receiver architecture depends on the synchronization method that is used. Orthogonal frequency division multiplexing (OFDM) is one of the most favourable technologies deployed in fourth generation systems. It is a multicarrier transmission technique, which essentially transforms the frequency selective fading channel into flat fading channel by divides the single wideband channel into number of parallel narrowband channels. Thus, simplifies the equalizer complexity. As we know every system has its own advantages and disadvantages, OFDM also suffers from its disadvantages. One of the main disadvantages of OFDM is its sensitivity to Carrier Frequency Offset (CFO). So, accurate estimation and compensation of CFO is the major task to be performed for proper reception of data. Furthermore, when OFDM technique is used along with MIMO systems, the task of CFO estimation becomes much more difficult due to the presence of multiple antenna interference (MAI). This paper takes an overall look at this issue. In this paper, we will discuss about Chu sequences and training sequence based CFO estimation for MIMO OFDM systems which use Chu sequence based training sequences for estimation purpose.

Abstract: One of the most serious problems in power system is voltage instability and losses. Improving the systems reactive power handling capacity via Flexible AC Transmission system (FACTS) devices is a remedy for prevention of voltage. This paper discusses the use of static var compensators (SVC) for reducing the total losses of a power system. National Grid of Sudan (NGS) transmission lines-500KV is used as case study. Solutions are obtained using Neplan software. The results show that the total losses is about 25.447 MW, which is reduced to 21.551 MW by installing static var compensator in main bus bar of kabashi.
