Investigation on Multipoint Measurement Techniques for PQ Monitoring

The problem of locating the sources of the harmonic distortion in power networks is still a critical task. Several methods based on multi-point measurement techniques have been recently proposed in the literature for harmonic pollution monitoring. The main goal of this study is to compare the two most powerful tools designed for this purpose. In this paper the results of both computer simulations on an IEEE test network and experimental tests performed by means of simultaneous measurements on an ad-hoc benchmark power system are presented along with a discussion on the practical usability of such monitoring techniques
