High Voltage DC Transmission Systems (HVDC),and others to develop an understanding of how to select, apply, and manage power electronic systems for conversion of AC to DC and vice versa and how to integrate HVDC links in AC systems. This introductory chapter provides some background as to how HVDC power transmission systems function and gives

Configurations of HVDC Links,The power conversion can be performed using different technologies but has since the 1950s employed electrical switches, which chops the AC voltages and currents supplied from a three-phase AC system to unidirectional DC power feeding DC circuits with one positive and one negative polarity.

Comparison of HVDC Converters,shed and capable of handling very large powers at high efficiency. They also are able to electronically suppress and recover from DC line faults with no requirement to open mechanical switchgear, which gives them a considerable advantage in comparison with AC transmission. However, they require shun

Measurement Transducers for LCC and VSC HVDC Converter Stations, operators and maintenance crews with information to ensure that the converter stations are safely operated and properly maintained. The measured quantities of the input and output of HVDC converter stations however cannot be directly connected to the protection and control systems due to the nature
