Development in HVDC Circuit Breaker - A Review

Abstract

The increasing adoption of High Voltage Direct Current (HVDC) systems for efficient long-distance power transmission and renewable energy integration necessitates advanced protection mechanisms to ensure system stability and reliability. Among these, HVDC circuit breakers play a pivotal role in interrupting fault currents and safeguarding HVDC networks. This review paper provides a comprehensive analysis of HVDC circuit breaker technologies, encompassing mechanical, solid-state, and hybrid designs. The paper discusses recent innovations and advancements in HVDC circuit breaker technology, including the integration of fault current limiters and novel switching mechanisms. Case studies of implemented HVDC circuit breaker systems are presented to illustrate practical applications and performance in real-world scenarios. Additionally, the review addresses future research directions in the development of HVDC circuit breakers, emphasizing the need for continued innovation to meet the evolving demands of modern power grids. This paper aims to serve as a valuable resource for researchers, engineers, and policymakers involved in the design and deployment of HVDC systems.
