9.14 Summary

With the increase of harmonic currents and voltages in present-day power systems, the installation of passive, active, and hybrid filters gains in importance. In the future, recommended practices such as IEEE-519 [11] will result in further increased use of filters within the distribution system. There are a great variety of filter configurations (Figs. 9.3 and 9.13 to 9.25). Classification of filters can be based on different criteria such as supply type, filter connection, number of filter elements, power rating, compensation type, speed of response, and control technique. In this chapter the classification of power filters is performed based on the type of supply (Fig. 9.3) and the control method (Section 9.7). Proper selection ...
