Based upon the increasing utilization of power electronics in electrical energy systems, high frequency combined with high voltage (HF-HV) phenomena are emerging. Fast switching operations, e.g. by static inverters with their large slew rates, are the origin of the stresses above 50/60 Hz. The impact of HF-HV noise on insulation systems like in power transformers has yet to be investigated and is...
Due to the increasing extension of power grids and decentralization of power generation, the need for control and compensation is more and more increasing. The intensive use of modern power electronics in FACTS elements can provide a feasible solution. Especially STATCOM and UPFC, for their versatile application can be the method of choice. Voltage sourced converters with IGBTs are used for compensation,...
