1. Measurements quality and redundancy evaluation for power system state estimation / Avaliação da qualidade e redundância das medidas para estimação de estado em sistemas elétricos de potência
The operating center requires much information in order to control and supervise the power systems. In a secure power systems operation it is important that the state estimation process be reliable. For that purpose, in this work: i) a computer program to evaluate and increment the reliability of power system in terms of redundancy and measurements availabil

2. Three-phase generalized state estimation / Estimação de estado generalizada trifasica
Since its introduction in 1969 by Fred C. Schweppe, J. Wildes and D. Rom, the power system state estimation has been widely studied. The state estimation is evolving to a more detailed modeling, which considers state variables not commonly used in bus/branch system modeling. A generalized state estimation model, in which switches and circuit breakers are rep

3. DETECÇÃO E IDENTIFICAÇÃO DE ANORMALIDADES NA ESTIMAÇÃO DINÂMICA DE ESTADO EM SISTEMAS DE POTÊNCIA / DETECTION AND IDENTIFICATION OF ANOMALIES IN POWER SYSTEM DYNAMIC STATE ESTIMATION
This work presents a comparison between the performance of dynamic and tracking estimators, in power systems operating under quasi-static conditions, concerning their characteristics of forecasting and filtering. From this comparison, a new dynamic estimator which incorporates the main advantages of the previous estimators is proposed. Also, a new scheme of
