چکیده انگلیسی

Power factor is well defined in sinusoidal situations, however, in the presence of harmonics, different power factors exist and they may provide different values in which case, evaluation becomes problematic. In Morsi and El-Hawary (2008) [1], [2] and [3], fuzzy systems have been used by the authors to develop a representative index that quantifies the power factor in different operating conditions including sinusoidal and non-sinusoidal situations. However, since different fuzzy operators can be used in the fuzzy system, which will affect the measured output power factor index, this paper investigates the implementation of different fuzzy operators when applied to the developed fuzzy system-based power factor evaluation, in different operating conditions. It is found that the use of the ‘algebraic product-sum’ operation offers the most suitable connection method, while the ‘algebraic product’ is the most preferred as an implication method and the ‘maximum’ operation is best suited for the aggregation operation. These combinations offer the most suitable means for establishing a representative power factor under non-sinusoidal conditions with the least computational burden.
