Abstract: Transmission of electrical energy with High Voltage Direct Current (HVDC) has provided the electric power industry with a dominant means to transmit huge quantity of electricity over very long distances. To investigate the performance, a well-developed current source converter based HVDC transmission system model is projected, in which the AC system represented as damped LLR equivalent and is equipped with double tuned harmonic filter to mitigate the AC-DC harmonics and the DC system is secured with rectifier current control, inverter current control and inverter voltage control. The MATLAB/ Simulink based simulation results validate the step response of HVDC transmission system with various controllers.
Keywords: HVDC transmission systems, Double tuned filter, Rectifier DC Current Control, Inverter DC Current-Voltage Control, Step response.
