A review of LCC-HVDC and VSC-HVDC technologies and applications

2016 IEEE 16th International Conference on Environment and Electrical Engineering (EEEIC), 2016
High Voltage Direct Current (HVDC) systems has been an alternative method of transmitting electric power from one location to another with some inherent advantages over AC transmission systems. The efficiency and rated power carrying capacity of direct current transmission lines highly depends on the converter used in transforming the current from one ...
