Impact of Midpoint STATCOM on Generator Loss of Excitation Protection

Impact of Midpoint STATCOM on Generator Loss of Excitation Protection Abstract: This paper explores the impact of a transmission-line midpoint STATCOM on the performance of the generator loss-of-excitation (LOE) protection. In this context, investigations are conducted on a two-hydrogenerator power station for two LOE contingencies, namely, a complete LOE due to a field-winding short circuit […]


Elimination of Coupling Transformer Core Saturation in Cascaded Multilevel Converter Based T-STATCOM Systems

Elimination of Coupling Transformer Core Saturation in Cascaded Multilevel Converter-Based T-STATCOM Systems Abstract: This paper deals with coupling transformer core saturation problem in cascaded multilevel converter (CMC) based transmission-type static synchronous compensator (T-STATCOM) systems. The effects of nonlinear characteristics of the coupling transformer and CMCs on the core saturation phenomenon are investigated, and the associated […]
