“…The transient fault current is effectively reduced with a larger current limiting reactor, which allows the DC circuit breaker to have longer time to clear the fault [8]. The reactance is in the range of tens of mH to a few hundred mH depending the HVDC grid voltage [8], [107]. However, the current limiting reactor causes conduction losses and also poses control challenges in the DC grid, which may affect stability of the DC grid [19].…”

HVDC circuit breakers are of increasing importance, as multi-terminal high voltage DC (HVDC) transmission becomes a commercial reality. Multiple HVDC breaker technologies have been developed, and are starting to appear as proof-of-concept installations on real networks. Information about them is however distributed widely in the literature. This paper describes the underlying challenges, the leading candidate solutions, and discusses the requirements and construction of the component subassemblies. Its goal is to provide a comprehensive overview of the field.

“…The current limiting reactor also can affect the behaviour of hybrid DC circuit breaker. The impact of the current limiting reactor on the hybrid DC circuit breaker is discussed in detail in [107]. The current limiting reactor can cause overvoltage of the DC circuit breaker after fault interruption.…”

“…In [201] the differences between IGBT-based and IGCT-based solid-state CBs are discussed. In [202] the operation of an hybrid CB in a HVDC power system is analyzed, with the aim of finding out the influence that the CB and the system parameters have on the overcurrents and overvoltages following a breaking action.…”

“…The hybrid HVDC breaker has been proposed and investigated in References [29][30][31] to eliminate on-state power loss and limit fault current within several milliseconds. Parametric analysis of hybrid DCCB has also been conducted thoroughly considering the influence of the main parameters on the system and the breaker design [32]. Moreover, an interlink DCCB has been proposed to maintain the fault current interruption ability with a few components to reduce the overall cost of the DCCB in the DC grid [33].…”

Enhanced Fault Current-Limiting Circuit Design for a DC Fault in a Modular Multilevel Converter-Based High-Voltage Direct Current System

et al. 2019

The main weakness of the half-bridge modular multilevel converter-based high-voltage direct current (MMC-HVDC) system lies in its immature solution to extremely high current under direct current (DC) line fault. The development of the direct current circuit breaker (DCCB) remains constrained in terms of interruption capacity and operation speed. Therefore, it is essential to limit fault current in the MMC-HVDC system. An enhanced fault current-limiting circuit (EFCLC) is proposed on the basis of fault current study to restrict fault current under DC pole-to-pole fault. Specifically, the EFCLC consists of fault current-limiting inductance L F C L and energy dissipation resistance R F C L in parallel with surge arrestor. L F C L reduces the fault current rising speed, together with arm inductance and smoothing reactor. However, in contrast to arm inductance and smoothing reactor, L F C L will be bypassed via parallel-connected thyristors after blocking converter to prevent the effect on fault interruption speed. R F C L shares the stress on energy absorption device (metal oxide arrester) to facilitate fault interruption. The DCCB requirement in interruption capacity and breaking speed can be satisfied effortlessly through the EFCLC. The working principle and parameter determination of the EFCLC are presented in detail, and its effectiveness is verified by simulation in RT-LAB and MATLAB software platforms.
