1. MODELOS DE PREVISÃO DE CARGA DE CURTO PRAZO / SHORT TERM LOAD FORECASTING MODELS
Application of two diferent metodologies, in order to model and forecast the behavior of time series of hourly electrical loads generated by ESCELSA. Was applied to the time series studied the metodology of the direct smoothing, and also a recent metodology, the Holt-Winters with multiple sazonalities. In both of them it has been done the hourly forecast (24

2. MODELO PARA PREVISÃO DA TEMPERATURA DE CONDUTORES DE LINHAS AÉREAS DE TRANSMISSÃO / MODEL FOR TRANSMISSION LINE CONDUCTORS TEMPERATURE FORECASTING
Transmission lines have a fundamental role in the electric system performance,connecting power sources to load centers. When the transmission system attains it`s transmission capability limit, the system must be expanded, either constructing new lines, or upgrading existing ones. Among the factors that can limit a transmission line transfer capability is the

3. MÉTODO DE AMORTECIMENTO DIRETO COM TRATAMENTO DA SAZONALIDADE ATRAVÉS DO MÉTODO HARMÔNICO DE HARRISON / DIRECT EXPONENTIAL SMOOTHING METHOD INCORPORATING SEASONAL COMPONENT MODELLED BY HARRISON HARMONIC APPROACH
The method of exponential smoothing, although originally propesed during the 60´s, still continues in use up to today. In this thesis we present a new forecasting method for time series / with and/or without seasonality, applying the theory of exponential smoothing and harmonic analysis. It is assume that the series is composed of secular trend (constant, l
