Abstract

This paper presents an efficient alternative method to estimate synchronous generators parameters using real time operating data. The main idea considers the use of Hybrid Legendre Block-Pulse functions for fitting measured input-output synchronous generator signals. This allows writing a set of linear algebraic equations that can be solved for the unknown parameters using the pseudo-inverse. The results obtained by this method show accuracy and robustness against the noise corruption in process and/or measurements. Therefore, this alternative utilizes two advantages: first, Integration for calculating basis functions coefficients, and averaging the signals, so that the noise corruption is highly reduced. Second, the minimum squared error concept is used in pseudo-inverse method, so that the remained error from previous stages is minimized.
