Abstract

This paper presents a brief explanation how Synchronized Measurement Technology (SMT) and WAMPAC architecture can support State Estimation and it discusses the existing correlation between each other. Additionally, it is presented a practical implementation of Phasor Measurement Units for updating network parameter data bases to improve the performance of state estimators. The methodology presented can be implemented only when full observability of the network parameters is available. The performance of the enhanced state estimator is assessed for different types of measurements and parameter errors. It is shown how the proposed solution delivers a more reliable estimation, especially when parameter errors are difficult to detect.
