To better understand the impact of commutation on inverter efficiency, let''s compare two commonly used commutation techniques: natural commutation and forced commutation (specifically
This paper proposes a calculation method for transient overvoltage caused by commutation failure in the high-voltage direct current transmission system for grid-connected new energy.
In the HVDC link system, this kind of faults also provide a voltage depression which lead to trigger a commutation failures in the inverter valves. In this paper we investigate the behavior of the HVDC inverter
Abstract: A thyristor commutation module with controllable output voltage and adjustable impedance during commutation is proposed to comprehensively address the commutation failure issue in Line-Commuted

Commutation failure (CF) is the main fault type in high voltage direct current (HVDC) systems with line commutated converters. To mitigate CFs, considerable researches have been
In the multi-infeed HVDC system, the interaction between inverter stations is an important factor that triggers the propagation of commutation failure. This paper aims to study the interaction mechanism of
To completely solve the problem of CF, we have proposed a novel hybrid commutated converter (HCC) technology based on reverse blocking integrated gate commutated thyristor, which can utilise two
This paper analyzes the influence of voltage amplitude reduction, zero-crossing displacement, and volt-age waveform distortion on the commutation process based on the phenomenon of commutation failure in HVDC
Abstract: Commutation failure is a common fault for line-commutated converters in the inverter. To reduce the possibility of commutation failure, many prediction algorithms based on alternating current (AC) voltage
To solve the commutation failure (CF) issues in high voltage direct current (HVDC) transmission systems based on line commutated converter (LCC), this paper proposes a hybrid solution combining the
With the increasing applications of high-voltage direct current inverters in heavy-load grids, commutation failures (CFs) pose a severe threat to the safe and stable operation of power
Through fault validation simulations conducted across three HVDC transmission systems, our strategy demonstrates effective suppression of commutation failure incidents within HVDC transmission
