The ability to measure and compensate for power line harmonics has become a growing area of interest because of today's commonly used electronic equipment. Since the number and relative magnitudes of the harmonics on the power line are a function of the load, estimation of an equivalent load can be accomplished. Because of variation in the load, the need for an adaptive algorithm is imperative. Thus far, few algorithms for determining harmonic contents have not dealt with the problem associated with the limited power of the line conditioner. This thesis deals with a previously known harmonic compensating algorithm and introduces a new algorithm which both compensates for harmonic noise and estimates the load as a transformation matrix depending on the associated transfer function of the active line conditioner in use
