Adaline and its application in power quality disturbances detection and frequency tracking

For power quality detection, several techniques have been proposed in the literature. In the paper, some shortcomings of the conventional methods that are usually used to analyze the power quality issues are firstly pointed out. A kind of artificial neural network, adaline, and its new algorithm for analysis of power quality are presented. The new algorithm has the advantages of being simply calculated and easily implemented through hardware. The simulating results of voltage quality disturbances detection and especially frequency tracking demonstrate that the new adaline and its algorithm can be applied to the precise analysis for power quality.
