Controlling of PMSG-Assisted Wind Energy Conversion System with Maximum Power Tracking Technique

This paper develops a dynamic model of small-scale wind energy conversion system (WECS) based on diode bridge rectifier and permanent magnet synchronous generator (PMSG). The simple and effective perturb and observe (P&O) algorithm has been proposed for extracting maximum power point tracking (MPPT) of wind turbine (WT) in the moderate-to-cutout wind speed region by sensing input parameters of DC–DC buck–boost converter. The MPPT algorithm in addition to the DC–DC converter is being simulated in MATLAB/Simulink software. The obtained characteristics show the effectiveness of P&O MPPT technique for extracting maximum power from the wind and delivering it appropriately to the resistive load.

Control Schemes for Permanent Magnet Synchronous Generator-Based Variable Speed Wind Turbine

In this paper, two control schemes such as direct control scheme (DCS) and vector control scheme (VCS) are presented for permanent magnet synchronous generator (PMSG) based adjustable speed wind turbine (WT) system. In DCS, all parameters are obtained in the stator reference frame to invalidate the need of continuous position of rotor. Furthermore, it is analyzed that the DCS acquires numerous advantages over traditional indirect VCS such as torque, flux control lacking any rotor location. It is lesser parameters dependence and sensor less operation. In both the techniques, the DCS can operate underneath fixed and dynamic wind velocity conditions. Both of these control schemes are implemented in MATLAB/Simulink software, and the obtained characteristics are shown which results effective and satisfactory performance.

Fingerprint Acquisition Methodologies and Its Upgradation with IoT

Fingerprint reader is an emerging technology, increasing at a tremendous rate due to its function that allows the fast identification and secure verification capabilities. This technology enables to recognize individual users without need of any password and the card swipes and works in a different ways rather than the swipe cards and other identification technologies. By using this technology, we can recognize and authenticate individuals based on the who they are, instead of the what they know, like their password and pins and what they possess, like keys and swipe cards. Fingerprint technology having important role with security application and e-commerce due to their ability of identifying and providing access to user through finger. This technology can be implemented in the various areas like Voters Identification, Passport verification, Population Census, Driver’s license, and Professional ID and there data can be placed on cloud by using Internet of Things (IoT). If cloud-based technology incorporated with fingerprint identification and is properly used, then it has potential to create a highly secured verification environment. In this research, we have done extensive literature survey for future research areas in this field.

Hardware Implementation of Solar Assisted Automatic Curtain Control System

An innovative effort on hardware design of an automatic curtain control system powered by solar PV array. To achieve the objective, a constant voltage controller (CVC) type maximum power point tracking (MPPT) method for PV system is implemented with a DC to DC boost converter circuit to fond maximum power. Also, a motor controller unit is implemented to control the motor run time used in this system. The proposed system circuits which include CVC-MPPT circuit boost converter and motor control unit have been designed using Proteus environment. The closing and opening of curtain has been tested under different light intensity level. The performance analysis of entire system is observed acceptable.

Performance Analysis of Automatic Cleaning System for Solar PV Modules

An experimental setup for automatic cleaning of dust fouling on photovoltaic (PV) system is designed. Comprehensive observations are carried out for numerous types of tracking and cleaning conditions for the extensive comparative study. In this context, the performance of the designed system is compared with stationary, sun tracking, and tracking with cleaning conditions in terms of open-circuit voltage, current, and power. The obtained results are carried out to evaluate the designed system performance for solar PV modules and/or array in tracking and cleaning conditions simultaneously, which are found satisfactorily and soupier. So, the present study is very helpful for the enhancement of the PV module efficiency and can be recommended to extract the maximum electrical energy from PV module in domestics as well as commercial applications.
