A Review Article on Power Stabilization of HVDC Transmission Line Using Facts VSC Technique

Abstract

This paper manages another three-level Voltage Source Converter (VSC) with its dynamic control and power quality improvement for High Voltage Direct Current (HVDC) framework. The proposed three-level voltage source converter (VSC) topology for HVDC framework comprises of two converter stations bolstered from two diverse air conditioning frameworks. The dynamic power is moved between the stations in any case. The receptive power is controlled freely in every converter station. The three-level VSC is worked at ideal dead point which gives the consonant execution proportionate to a two-level 24-beat voltage source converter. The two converters stations can be worked as either a rectifier or an inverter as per their course of dynamic power stream. These VSC based converters are worked at Fundamental Frequency Switching (FFS) to diminish the misfortunes in the framework. A control calculation is created for bidirectional dynamic power stream, autonomous responsive power control for both rectifier and inverter stations. The proposed converter topology is found exceptionally appropriate for high power rating frameworks and this outcome in a significant decrease in exchanging misfortunes and keeping away from extra receptive influence plant and channel courses of action. Reenactment is conveyed to check the presentation of the proposed VSC topology and control technique for bidirectional dynamic power stream and their autonomous responsive power control.
