The HVDC SuperConTM control system employs tough UAPC platform designed by NR Electric. It adopts hierarchical structure, redundant design, robust control functions and comprehensive protection scheme . It monitors, controls and protects all AC and DC in the VSC – HVDC transmission system.
control scheme of one VSC – HVDC converter station is shown in the Fig. 4 below [1, 8]. The control functions of VSC – HVDC system can be classified by three control layers: system control layer, application control layer, and converter control layer as shown in Table I. The system layer controller establishes the, for voltage-source converter high-voltage direct-current transmission schemes due to … A detailed MMC model for a typical VSC – HVDC scheme , employing the traditional detailed model (TDM) converter arm representation, has been developed. … The converter transformer employs a.
The HVDC link employs TDKs MKK DCi-R power capacitors measuring 600mm in height, 350mm in length, and 160mm in width. Contractors involved ABB was awarded a contract by SGCC for the supply of the VSC – HVDC light valve system, transformers components, capacitors, semiconductors, and wall bushings in November 2018.

Comparison of HVDC Light (VSC) and HVDC Classic (LCC) Site … – ABB, HVDC converter – Wikipedia, HVDC converter – Wikipedia, HVDC converter – Wikipedia, VSC – HVDC converter or a LCC- HVDC scheme . The CTL arrangement offers a smaller overall site footprint and a lower building height than both the 2-level and LCC- HVDC alternatives. However, this is at the expense of increased converter building size.
Abstract High Voltage Direct Current system based on Voltage Source Converters ( VSC – HVDC ) is becoming a more effective, solution for long distance power transmission especially for off-shore wind plants and supplying power to remote regions Confronting with an increasing demand of power, there is a need to explore the most efficient and reliable bulk power transmission system.
This mega- HVDC scheme is named KunLiuLong, the combination name of the three converter stations. Kun refers to Kunming North Converter Station (LCC 8GW). Liu refers to Liuzhou North Converter Station ( VSC 3GW). Long refers to Longmen Converter Station ( VSC 5GW). The DC voltage for the scheme is 800kV.
An HVDC converter converts electric power from high voltage alternating current (AC) to high-voltage direct current ( HVDC ), or vice versa. HVDC is used as an alternative to AC for transmitting electrical energy over long distances or between AC power systems of different frequencies. HVDC converters capable of converting up to two gigawatts (GW) and with voltage ratings of up to 900 kilovolts …
