Prediction of radio interference from HVDC transmission lines based on corona discharge characteristics

open access: yesHigh Voltage, 2020
Many research works have proved that it is viable to predict the radio interference (RI) of high-voltage alternating current transmission lines by corona cage test. However, it is uncertain whether the same method can be adopted for RI prediction of high-

Renewable sources integration using HVDC in parallel to AC traditional system: the Adriatic project

open access: yes, 2019
Along the Adriatic coast, the Italian transmission system consists of a single 400 kV North-South Line. This limits the power transfer capacity between the Center North and Center South market zones and with the risk of overload in case of high renewable

Coordinated DC Fault Ride‐Through Control for a Grid‐Forming Wind‐Storage System With VSC‐HVDC Integration Under Transmission Constraints

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
Due to complex wind farm conditions, a coordinated control system was designed. It manages DC power surges during AC faults by temporarily storing excess energy and regulating voltages. This strategy optimizes unbalanced power and enables effective fault recovery, resulting in minimal voltage fluctuations and superior performance.

HVDC-Transmission Line Model for Transient Simulation Purposes

open access: yesIFAC Proceedings Volumes, 1992
Abstract A lumped bipolair HVDC-transmission line model, based on least squares fitting of orthogonal polynomials, which are space dependent, and have time dependent coefficients, is presented and examined in this paper. The model enables the line voltage and current to be approximately determined for arbitrary points along the line and at arbitrary ...

Hybrid HVDC for supply of power to offshore oil platforms

open access: yes, 2004
A HVDC hybrid system, comprising a line commutated thyristor HVDC converter and a STATCOM, is proposed in this paper for supplying power to offshore oil platforms that do not have their own generation. The proposed system combines the robust performance,

HVDC tie links in smart power grids: A versatile control strategy of VSC converters

open access: yes, 2021
The forced switching converters are the kernel of the modern paradigm of VSC-HVDC system. It is widely recognized that appropriate control laws make these converters more advantageous than the traditional line commutated ones.
