Grid Frequency Control for LCC HVDC Link Connected Wind Farms

IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society, 2007
In this paper we consider the design for the offshore grid frequency control in a DFIG-based wind farm with LCC HVDC link connection. The control approach is based on using the grid frequency to regulate the HVDC DC-link current and hence control the power flow in the system.

Frequency Scan Based Stability Analysis of an LCC-HVdc System

2019 IEEE Canadian Conference of Electrical and Computer Engineering (CCECE), 2019
Frequency scanning is a method for extracting the small-signal model of a power electronic system (PES) by injecting a wide-band signal in its time-domain simulation at steady state. This paper presents the stability analysis of the interactions between a Line Commutated Converter HVdc system (LCC-HVdc) and its ac grid using a frequency scanning ...

Control of two LCC-HVDC interconnected through DC-DC autotransformer

12th IET International Conference on AC and DC Power Transmission (ACDC 2016), 2016
This paper studies the power flow control of two LCC-HVDCs interconnected through DC-DC Autotransformer. The interconnecting scheme and its potential benefits are firstly summarized. Natural instability of using conventional LCC controller in the interconnected system is identified.

LCC-HVDC Bipole System with MMC-Based DC Tapping Stations

2022
Line Commutated Converter based High Voltage DC (LCC-HVDC) is the dominant technology of HVDC power transmission worldwide. LCC-HVDC has lower cost of implementation and lower power losses, accompanied by higher voltage capabilities and higher power levels, in comparison to Voltage Source Converter based HVDC (VSC-HVDC) technology. However, VSCHVDC has
