Abstract

In view of the noise which is easily caused during operation of the static var compensator

in this paper

a kind of signal correction algorithm of static var compensator based on compressed sensing is proposed. The compression perception algorithm can provide many different features of the mapping dictionary baseand identify the components of a number of noise signals generated by the static var compensator. The correction and elimination of noise interference is achieved by thresholding and reassigning values in the transform domain. The efficiency of noise cancellation is several times that of wavelet soft thresholding.
