Right Selection of Inverter Systems and Harmonics Reduction A Means of Enhancing Power Infrastructure in Nigeria

The paper examines various types of inverter systems available in the markets in terms of their waveforms, harmonics and quality by taking the ideal Sinusoidal waveform as a reference. It illuminates some vital information on various types of inverters and their technologies. It identifies harmonics distortion has an important criterion for selecting a power inverter. It shows in lucid manner how to mathematically determine Total Harmonic Distortion THD of a waveform. It calculates the harmonics content of a Square wave inverter and proffer solution on how to reduce them. The resultant is an empowerment of power electronics engineers to distinguish which of the types to purchase in order to optimally improve national infrastructure and to enhance values of their scarce resources.

Regenerative Braking System

Regenerative braking system is a small, but an eventual method for converting unwanted heat energy into electrical energy. The energy generated is stored in the battery. This helps in reducing the usage of the external battery for charging purposes. These types of brakes helps in increasing the driving range for the electric vehicles as they can travel for longer periods. Regenerative braking system also in improving the fuel economy. It is a way of increasing the efficiency rate of the vehicles. Instead, of converting the kinhetic energy into thermal energy through friction braking this system can convert a good fraction of kinetic energy into electric energy and charge the battey using the principle of alternator.

Modeling and Simulation of Unified Series Shunt Compensator for Power Quality Improvement

Power Quality in the distribution system is the important issue for industrial, commercial and residential applications. An increasing demond for high quality, reliable electrical power and an increasing number of distorting loads have led an increased awareness of power quality both by customer and utilities. This paper deals with the simulation of a Unified series shunt compensator, which is aimed at mitigating most of the Power Quality problems such as Voltage sag compensation, Voltage swell compensation, Voltage Flicker reduction, Voltage Unbalance mitigation, UPS mode operation. The modeling and simulation of the USSC has been carried out by using Facts controller. The USSC simulation model comprises of two 6 pulse inverters which are connected in series and in shunt to the system. The USSC is designed by using MATLAB SIMULINK based simulation for the working of the USSC. The USSC has mitigated several Power Quality problems giving better performance.

Arduino Based Smart Home Automation System

This paper presents the design and prototype implementation of the automation system that can be used two Arduino Nano with sensors. To demonstrate the effectiveness of this system, the devices such as LDR, temperature sensor, smoke sensor and motion sensor have been integrated with the automation system. In addition, the GSM and RFID modules are also used for security system. The functions of the sensors are to monitor and control the light, the room temperature and alarms. The main goal of the security system is GSM which is used to send the SMS alerts to the owner. Two Arduino Nano control sensors and relays that monitor a defined location and take action based on specified parameters like ambient light, temperature, etc. The microcontroller will send SMS to the owner if the sensors detect an abnormality. In addition, door lock security is developed by RFID module. In this paper, the presents of GSM module security system make more secure and reliable.

GPS and GSM Based Vehicle Tracking System

A vehicle tracking system is very useful for tracking the movement of a vehicle from any location at any time. An efficient vehicle tracking system is designed and implemented for tracking the movement of any equipped vehicle from any location at any time. The proposed system made good use of popular technology that combines a smartphone with an Arduino UNO. This easy to make and inexpensive compared to others. The designed in vehicle device works using Global Positioning System GPS and Global System for Mobile Communication GSM technology that is one of the most common ways for vehicle tracking. The device is embedded inside a vehicle those positions is to be determined and tracked in real time. An Arduino UNO is used to control the GPS receiver and GSM module. The vehicle tracking system uses the GPS module to get geographic coordinates at regular time interval. The GSM module is used to transmit and update the vehicle location to a database. This paper gives minute by minute update about vehicle location by sending SMS through GSM modem. This SMS contain latitude and longitude of the location of vehicle. Arduino UNO gets the coordinates from GPS modem and then it sends this information to user in text SMS. GSM modem is used to send this information via SMS sent to the owner of the vehicle. Location is displayed on LCD. And then Google map displays location and name of the place on cell phone. Thus, user able to continuously monitor a moving vehicle on demand using smartphone and determine the estimated distance and time for the vehicle to arrive at a given destination.

Experimental Investigations and Computational Analysis on Subsonic Wind Tunnel

This paper disclose the entire approach to design an open circuit subsonic wind tunnel which will be used to consider the wind impact on the airfoil. The current rules and discoveries of the past research works were sought after for plan figuring of different segments of the wind tunnel. Wind speed of 26 m s have been practiced at the test territory. The wind qualities over a symmetrical airfoil are viewed as probably in a low speed wind tunnel. Tests were finished by moving the approach, from 0 to 5 degree. The stream attributes over a symmetrical airfoil are examined tentatively. The pressure distribution on the airfoil area was estimated, lift and drag force were estimated and velocity profiles were acquired.

Waste Management System by Using IoT

Solid waste management is one of the major aspect which has to be considered in terms of making urban area environment healthier. The common dustbins placed by the municipal corporation are leading number of health, environmental and social issues. Various causes are like improper dustbin placement in city, improper system of collecting waste by City Corporation, and more specifically people are not aware enough to use dustbins in proper way. These various major causes are leading serious problems like, an unhygienic condition, air pollution and unhealthy environment creating health disease. Up till now, research has been carried out by developing a Software Applications for indicating dustbin status, another by shortest part method for garbage collecting vehicles by integrating RFID ,GSM, GIS system but no active efforts has been taken paying attention towards managing such waste in atomized way. Considering all these major factors, a smart solid waste management system is designed that will check status and give alert of dustbin fullness and more significantly system has a feature to literate people to use dustbin properly and to literate people to use dustbin properly and to automatically sense and clean garbage present outside the dustbin. Thus presented solution achieves smart solid waste management system.
