The influence the angles of delay and overlap in the rate of harmonic in HVDC

To ensure efficiency, the DC HVDC transmission is an important application in the electrical energy process. This technique is mainly used for long-distance power transmission and interconnection of independent power grids. The conversion unit is the most important part of a HVDC transmission system, which performs the conversion of AC to DC. A major disadvantage is that the conversion is associated with generation of current and voltage harmonics. The purpose of studying and analyzing the harmonics generated by the converters with a power transmission link HVDC at both ends (point to point), uses conversion units to thyristor. The simulation is performed using Matlab / Simulink.
