Analysis of the Problems Occurred Due To Partial Shading of Solar Photovoltaic Array and Probable Solutions
Get PDFA solar panel is made up of solar cells where semiconductors made to react and give us a potential difference when solar energy falls on it. However, due to the internal and external interferences, many problems are faced by solar panels, like dust, partial shading by leaves or mud, etc. This paper aims at trying to find out the best possible solution for the partial shading problems when solar energy is harvested using a solar panel. The Series-Parallel configuration (SP) and the Total-Cross Tied configuration (TCT) connections of PV module have been analyzed using MATLAB
Review on Design and Simulation of Electricity Theft Detection and Protection System with their techno-economic Study
Get PDFTheft of electricity is a major problem faced by both developed as well as developing countries. It affects both the power as well as economic situation. It also at times is the root cause of blackouts. The objective of this paper is to design and simulate a system that can detect, which in turn, will help in protection from electricity theft
Automatic Cable Fault Distance Locator using Arduino
Get PDFThis paper presents the method of design of a cable fault location sensor for underground cable fault detection. The aim was to detect the fault location from transmitting or receiving station up to few meters accuracy using an Arduino based kit. The underground cable-based supply system is a common practice in urban areas. As explained in the paper, the system uses the principle of a Varley loop to determine the exact distance of the fault in the underground cable up to the accuracy of a meter. When any fault, e.g. short circuit and earth fault occurs, the length of the fault of the cable can be determined from the fault resistance using the bridge in the Varley loop. A microcontroller is used to make the necessary calculations and display the fault distance after that. After necessary calibration and testing, an accuracy of about 85% is achieved in locating the fault using the method
Health Monitoring of Induction Motor through Vibration Analysis
Get PDFMachinery monitoring is the process of monitoring a parameter of condition in machinery, such that a significant change is indicative of a failure in development. Temperature, vibration, noise, current, voltage, acoustic emission, etc. – all these measurements are used for machine condition monitoring. Measuring vibration signals of the Non-Destructive Testing (NDT) method is widely used to detect machine faults. There are many studies for the prediction of mechanical wear, fault and failure in this area for several decades. Signal processing techniques are used to obtain vital characteristic information from the vibration signals. This paper attempts to summarize the results of an evaluation of vibration analysis techniques as a method for diagnosis for three-phase induction motors
Arduino Based Automatic Irrigation System
Get PDFIn the present days, the farmers are suffering from severe drought like condition throughout the year. The main objective of this paper is to provide a system leads to automatic irrigation thereby saving time, money power of the farmers, gardeners in greenhouses etc. Manual intervention is common in traditional farm-land irrigation techniques. This paper presents a technique for Arduino based Automatic Irrigation System. With this automated technology of irrigation, human intervention can be minimized. The moisture sensors will be bedded in on the field. Whenever there is a change in water concentration, these sensors will sense the change and gives an interrupt signal to the microcontroller. Soil is one of the most fragile resources whose soil pH property used to describe the degree of the acidity or basicity, which affects nutrient availability and ultimately plant growth. Thus, the system will provide automation, remote controlling and increased efficiency. The humidity sensor is connected to internal ports of microcontroller via comparator; whenever there is a fluctuation in temperature and humidity of the environment, these sensors sense the change in temperature and humidity and give an interrupt signal to the micro-controller and thus the motor is activated. A buzzer is used to indicate that the pump is on
Transformer Oil Quality Diagnostic Using Spectroscopy Techniques - A Review
Get PDFTransformer serves as a vital component in the electrical energy supply system. In order to have an uninterrupted power supply, it is essential to timely monitor the condition of the transformer. A transformer has many components, out of which the transformer oil is one of the most crucial. It provides insulation and keeps the transformer cool. With ageing, the quality of the transformer oil degrades, and it loses its insulation properties that become a threat to the supply system. Optical Spectroscopy has gained a lot of attention in monitoring the quality of transformer oil in the past few years for various advantages. This paper reviews some of the commonly applied Spectroscopy techniques to monitor the various components of transformer oil by which we can predict the quality of the oil

Design and Development of Solar Insolation Simulator
Get PDFTo get the desired atmosphere for laboratory work is a difficult job for researchers. Specially, it is very much unreliable to get the required solar irradiance directly from the Sun. To solve this issue, a solar insolation simulator is designed and fabricated, through which the insolation can be easily controlled with the help of Arduino based system. In this simulator, solar energy is simulated using halogen bulbs, which provide the necessary insolation. The light dependent resistor (LDR) connected to the Arduino measures the amount of solar insolation falling on the solar PV module. A fan is used to extract out the access heat generated by the bulb
Smart Vehicle System using Arduino
Get PDFTransportation is a basic need of society and with the increasing population; indirectly there is an increase in the vehicle density, which may lead to many road accidents resulting in injuries and sometimes lead to death. To prevent this particularly, a system has been designed for accident location detection, accident prevention due to the upper issue of the dipper and anti-collision system. In this system, the shock sensor, ultrasonic sensor and temperature sensor are used as an input to the system along with GPS and GSM for real-time analysis and corresponding responses are analyzed; if any hazard occurs, the processing unit (Arduino) will take the appropriate action
