Previous issue date: 2007-07-30 / This work purposes the application of a methodology to optimize the implantation cost of an wind-solar hybrid system for oil pumping. The developed model is estimated the
implantation cost of system through Multiple Linear Regression technique, on the basis of the previous knowledge of variables: necessary capacity of storage, total daily energy demand, wind power, module power and module number. These variables are gotten by means of sizing. The considered model not only can be applied to the oil pumping, but also for any other purposes of electric energy generation for conversion of solar, wind or solar-wind energy, that demand short powers. Parametric statistical T-student tests had been used to detect the significant difference in the average of total cost to being considered the diameter of the wind, F by Snedecor in the variance analysis to test if the coefficients of the considered model are significantly different of zero and test not-parametric statistical by Friedman, toverify if there is difference in the system cost, by being considered the photovoltaic module powers. In decision of hypothesis tests was considered a 5%-significant level. The
configurations module powers showed significant differences in total cost of investment by considering an electrical motor of 3 HP. The configurations module powers showed
significant differences in total cost of investment by considering an electrical motor of 5 HP only to wind speed of 4m/s and 6 m/s in wind of 3 m, 4m and 5 m of diameter. There was not significant difference in costs to diameters of winds of 3 m and 4m. The mathematical model
and the computational program may be used to others applications which require electrical between 2.250 W and 3.750 W. A computational program was developed to assist the study of several configurations that optimizes the implantation cost of an wind-solar system through
considered mathematical model / Este trabalho prop?e a aplica??o de uma metodologia para otimizar o custo da implanta??o de um sistema h?brido e?lico-solar para bombeamento de petr?leo. O modelo desenvolvido
estima o custo da implanta??o do sistema por meio da utiliza??o da t?cnica de Regress?o Linear M?ltipla, com base no conhecimento pr?vio das vari?veis: capacidade necess?ria de armazenamento, demanda di?ria total de energia, pot?ncia do aerogerador, pot?ncia de m?dulos e n?mero de m?dulos, sendo estas vari?veis obtidas por meio de dimensionamento.
O modelo proposto pode ser aplicado n?o somente ao bombeamento de petr?leo, mas tamb?m para quaisquer outras finalidades de gera??o de energia el?trica por convers?o da energia e?lica, solar ou e?lica-solar que demandem baixas pot?ncias. Foram utilizados testes estat?sticos param?tricos tais como o T-student, para detectar a diferen?a significativa na m?dia do custo total ao ser considerado o di?metro do aerogerador; o F de Snedecor, na an?lise de vari?ncia para testar se os coeficientes do modelo proposto s?o significativamente diferentes de zero e o teste estat?stico n?o-param?trico de Friedman, para verificar se existe
diferen?a no custo do sistema, ao ser considerado as pot?ncias dos m?dulos fotovoltaicos. Na decis?o dos testes de hip?teses considerou-se um n?vel de signific?ncia de 5%. As
configura??es de pot?ncias dos m?dulos apresentaram diferen?as significativas no custo total do investimento ao ser considerado um motor el?trico de 3 HP. As configura??es de pot?ncias dos m?dulos apresentaram diferen?as significativas com motor el?trico de 5 HP somente para velocidades de vento de 4 m/s e 6 m/s em aerogeradores de 3 m, 4 m e 5 m de di?metros. N?o existiu diferen?a significativa nos custos para di?metros de aerogeradores de 3 m e 4 m. O modelo matem?tico e o programa computacional podem ser utilizados para outras aplica??es que requeiram pot?ncia el?trica entre 2.250 W e 3.750 W. Desenvolveu-se um programa
computacional para auxiliar o estudo de v?rias configura??es, o qual otimiza o custo de implanta??o de um sistema e?lico-solar com base no modelo matem?tico proposto
