Abstract:
The recent developments in semiconductors and control equipment have
made the voltage source converter based on high voltage direct current (VSC-
HVDC) feasible. Due to the use of VSC technology and pulse width
modulation (PWM) the VSC-HVDC has a number of potential advantages as
compared with classic HVDC, such as short circuit current reduction, rapid
and independent control of active and reactive power, etc. With those
advantages VSC-HVDC will likely be widely used in future transmission and
distribution systems.
In this thesis, the scenario of VSC-HVDC focus on the performances
evaluation of the complete VSC-HVDC transmission system accommodates
power between two active networks. The performance assessment include the
robust of converter control system during active power step change, system
stability during three phase fault and system stability during dc link fault. The
analysis of results have been done in the MATLAB program.
