Abstract
Design Trade-Offs of Modular Multilevel Converter-Based Arbitrary Wave Shape Generator for Conventional and Unconventional High Voltage Testing
Highlights
High Voltage (HV) equipment in the electrical power system such as switchgear, cables, and transformers are experiencing new electrical stresses due to the rise of Distribution Generation (DG) systems and large renewable energy integration by power electronic converters [1] [2]
The submodule capacitor voltages are balanced by the circulating current circuit, which is essential for the voltage magnitude accuracy
This paper introduces the huge potential of Modular Multilevel Converter (MMC) to generate complex arbitrary waveforms with good accuracy for HV Arbitrary Wave shape Generation (AWG) application
Summary
High Voltage (HV) equipment in the electrical power system such as switchgear, cables, and transformers are experiencing new electrical stresses due to the rise of Distribution Generation (DG) systems and large renewable energy integration by power electronic converters [1] [2]. Conventional HV dielectric test sources i.e., transformers (cascaded and resonant), impulse generators, and rectifier circuits, face many limitations in terms of flexibility to generate different wave shapes, current rating, as well as time-consuming to build a customized test setup Since these new electrical stresses are mainly generated by the switching mechanisms of the Semiconductor (SM) devices, the same ingredient is chosen to develop a programmable HV test source for future and advanced dielectric tests of various grid assets. In the linear region of operation, SM devices exhibit relatively high losses [3], restricting
