Study on Circuit Breaking Mechanism in Modern HVDC Power System

Abstract

The innovation of high-voltage direct current (HVDC) has sparked a great deal of interest over the last few decades, attributed to the fast development of possible voltage levels, transmission capabilities and transmission lengths. These developments happened in a time when power system applications such as renewable energy production (e.g., energy produced in offshore wind power plants), power trades through asynchronous networks, undersea cables and longdistance overhead transmission lines have increased in popularity throughout the world. The VSC based High Voltage Direct Current is the best effective and dependable means of transmitting electrical power across great distances. The most challenging aspect of the VSCHVDC system is the requirement for fast HVDC circuit breakers, as short-circuit failures cause damage to the converter valves and transmission network. The purpose of this study is to summarize HVDC circuit breaker technology, as well as recent substantial efforts within the creation of latest HVDC circuit breakers. Each technology is given a brief functional study. Furthermore, numerous technology primarily based totally on statistics accumulated from literatures are contrasted. Finally, hints for enhancing circuit breakers are provided.
