Abstract

The progress of high voltage and high-power semiconductor devices is mainly owing to the continuous penetration of power electronic technologies into the power system. These fully controlled semiconductor devices are mainly thyristor and IGBT based technologies. HVDC-LIGHT delivers fast and autonomousregulator of real and reactive power. LCC has certain advantages, like fewer stations. Losses, good over load capacity, bulk power transmission to large areas. In this work, the rectifier controller and inverter controller are designed and implemented. The steady-state characteristics of HVDC light and LCC-HVDC systems are studied using a steady state model. It is possible for both HVDC light and LCC-HVDC systems to control power flow independently at the rectifier and inverter stations that use the decoupled d-q vector control approach. The simulation results from MATLAB are used to compare DC link voltage, active power and reactive power with their respective reference values for both HVDC light and LCC-HVDC systems. The HVDC-LIGHT system outperforms the LCC-HVDC system in terms of transient response characteristics, peak overshoot, and settling time.
