In practical industry fields, harmonic, negative sequence current and reactive current need to be restrained to meet the requirements of consumers. The active power filter is a new brand power electronics device. In the three-phase unbalanced circuit, it can restrain the negative sequence fundamental current except for restraining harmonic. In order to restrain harmonic and negative sequence fundamental...
To solve the problems caused by unbalanced load in industrial fields, two novel methods to extract harmonic current and reactive current and a 2/2 transformation matrix are proposed based on instantaneous power theory, enabling APF to extract base positive sequence current, base negative sequence current and other high order harmonic current correctly and timely, thus we can choice compensation strategy...
