摘要：

This paper presents a method based on fuzzy linear estimation for voltage flicker measurements. The proposed algorithm uses the digitized samples of the voltage signal at the location where the power quality standards are implemented. The voltage signal is modeled as a fuzzy linear parameter estimation problem, where the coefficients are assumed to be fuzzy having certain middle and spread. A triangular membership is assumed. The linear programming based simplex method is used to solve the resulting linear optimization problem. Results for simulated examples are given in the text. (C) 2006 Elsevier Ltd.
