The modern High Voltage Direct Current HVDC transmission technology depends on the development of power electronics based on the semiconductor devices. This paper represents a simple model of HVDC transmission system in which the converter and filter have been designed to increase stability of power transmission. Using this model, current - voltage C-V characteristics have been simulated for steady state condition. It has also been studied for different fault conditions.

Documentation Help Center. The rectifier and the inverter are pulse converters using two 6-pulse thyristor bridges connected in series. The rectifier and the inverter are interconnected through a km distributed parameter line and two 0. The transformer tap changers are not simulated and fixed taps are assumed. Open the two transformer blocks in the Rectifier and Inverter subsystems to see the factors applied on the primary voltage: 0. Reactive power required by the converters is provided by a set of capacitor banks plus 11th, 13th and high pass filters for a total of Mvar on each side.

Thyristor-Based HVDC Transmission System (Detailed Model)

Functioning of complex HVDC transmission system converter can be obtained by analytical modeling. Developing countries like India and China with their ambitious power capacity enhancement program are installing more HVDC systems for long distance transmission. More can be obtained from huge investments in complex HVDC systems if operation and maintenance personnel have deeper understanding about the functioning of these systems. The model also helps in understanding the role and importance of AC filters. Great reliability.

Results obtained from the transmission line wavelet transforms are shown on the time domain and the frequency domain.
