This paper introduces artificial neural network (ANN) for long term wind speed prediction. The online available dataset of 26 cities from NASA are used to evaluate the performance of ANN model. Data of 22 cities are used for training the neural network and remaining 4 cities data samples are used for testing purpose. Air temperature, earth temperature, relative humidity, daily solar radiation, elevation,...
As interest towards solar energy is increasing therefore maximum power generation becomes an important issue. With photovoltaic systems power is maximized by using tilt angle resulting in optimum sizing and maximum power. Therefore optimum tilt angle (OTA) for 15 sites of Himachal Pradesh, India are calculated for installation of PV based standalone and hybrid system. The new correlations of annual...
Measured value of minimum air temperature, maximum air temperature, average air temperature and solar radiation between 1 January 2012 to 31 April 2014 for Hamirpur city in Himachal Pradesh, India are used for prediction of daily global solar radiation (DGSR) with artificial neural network (ANN) technique. The prediction of DGSR are made with three combinations of input variables namely: (i) average...
The dissolved gas-in-oil analysis (DGA) is a prevailing methodology being widely used to detect incipient faults in power transformers. However various methods have been developed to interpret DGA results, they may sometimes fail to diagnose precisely. The incipient fault identification accuracy of various artificial intelligence (AI) based methodology is varied with variation of input variable. Thus,...
The main objective of present study is to compare ANN model develop with neural network fitting tool (nftool), Radial Basis Function Neural Network (RBFNN) in predicting solar radiation for power generation. The three combinations of input variables are considered for prediction. The RBFNN utilizing input parameters as latitude, longitude, height above sea level and sunshine hours has mean absolute...
UV-Spectrophotometer response is a nonintrusive test used to determine the transformer integrity. Information about the health of the power transformer that can be use to plan cost, maintenance, relocation and operational criteria can be accurately interpreted using UV-Spectrophotometer. As UV scan can only show the pictorial information of the age of the oil hence it is not advantageous in all aspects...
The gases generated in oil filled transformer can be used for determination of incipient faults. Dissolved gas analysis (DGA) of transformer oil has been one of the most power full methods to detect the faults. The various methods such as liquid chromatography, acoustic analysis, and transformer function techniques are require some experience to interpret observations. The researchers have used artificial...
