Analisis Simulasi Pengaruh Cuaca terhadap Model Perubahan Energi Angin di Pulau Nias

Abstract

The study has been conducted on the effects of weather on the analysis simulation model of wind energy changes on the Nias island during the years 2009 to 2013. This study aims to determine the shape and size of the value of the parameters of the weather and its impact on the wind energy. This analysis is done in two stages. The first stage is done by analyzing the first few weather parameter ie wind speed, temperature and air pressure using the weibull distribution. The purpose of this weibull analysis is to get the amount of wind energy and to see how the shape and magnitude of the value of weather parameters. The second phase followed by simulating wind speed, temperature and air pressure into linear regression to see the effect of these parameters on the wind energy. The results of the analysis of data using the Weibull distribution for 2009-2010 states that the shape and scale parameters to obtain wind speed of 6.06 and 2.27 m I s, the shape and scale parameters for the temperature of 11.31 and 27.25 C, shape parameter and scale to the air pressure at 1546.69 and 1009.77 (mm / bar). Simulation with multiple linear regression equation yields the equation; E: - 7l + 15,5 V 0263 T + 0,056 P. ideal energy obtained on the island is 13.57 Watt with errata 4%. These results suggest that the development of wind power to the island of Nias still not able to meet the increase in the supply of electrical energy PLTGB Nias with a capacity of 8 MW in 2014 and the power plant with a capacity of 2l MW Nias in 2014-2015'
