Power Electronics Applications, Part 3

Abstract

This chapter explains power electronics applications in the area of utility power systems, primarily from the viewpoint of control. It discusses var generation/compensation technology based on static power electronic applications. Advanced power electronics technology has also had a significant impact on conventional power equipment and has led to the creation of new power equipment. Further, most power electronic switching equipment causes higher harmonics. Power electronic equipment has the characteristics to generate harmonics. The DQ method is a useful approach that can be applied to a wide range of power electronics applications. In modern hydro, thermal, and nuclear power-generating stations, most of the generators are equipped with solid-state generator excitation systems, which are of course composed of power electronic DC excitation current-generating systems. DC transmission systems are power electronic applications with the largest MVA capacities and highest kV voltages. Under certain circumstances, we need to transmit power over DC transmission lines.
