The Adaptive Linear Element (ADALINE) as seen in [9]
- [12], when considered for harmonic detection can
determine harmonics in just half cycle of the fundamental
period. This algorithm serves good for harmonic tracking in
a real time environment due to its faster convergence rate. In
this paper, a Modified ADALINE algorithm with a TimeVariant
Widrow – Hoff rule has been proposed for harmonic
detection. This algorithm incorporates all the merits of
ADALINE together with a reduced error, to attain
maximum convergence.
