Hybrid Commutation Converter in HVDC Systems

Materials Science Forum, 2010
This paper deals with DC – AC static converter systems, of very high voltages and currents, used for electricity power transmission. It has been analyzed three types of converters: with forced commutation, with commutation from load and the solution proposed by the authors. There are shown the advantages in hybrid switching converters, which in essence

Power Reversal of Hybrid HVDC System

11th IET International Conference on AC and DC Power Transmission, 2015
Hybrid HVDC combines the advantages of line commutated converter (LCC) and modular multilevel converter (MMC). In this paper the topology and basic control strategy of hybrid HVDC are described. Then the power reversal of hybrid HVDC is analysed. For LCC-HMMC (MMC adopting half bridge sub-module), the sequence of power reversal after stopping operation

Fullbridge MMC control for hybrid HVDC systems

2017 Brazilian Power Electronics Conference (COBEP), 2017
The Fullbridge based Modular Multilevel Converter (FBMMC) has been widely considered as one of the best solutions for High Voltage Direct Current (HVDC) systems, especially due to its capability of limiting dc short-circuit currents. Generally, the use of FBMMC on hybrid HVDC configurations with Line Commutated Converters (LCC) is considered for ...

Hybrid HVDC system for multi-infeed applications

2013 International Conference on Emerging Trends in Communication, Control, Signal Processing and Computing Applications (C2SPCA), 2013
The application of HVDC for stabilizing the large interconnected AC networks are resulting in several HVDC links inverting in the close electrical proximity. These multi-infeed HVDC system inverting into a weak AC network are of serious concern. One of the possible solution for better stability is using a VSC-HVDC as one of the infeed for the multi ...
