A current deviation control parameter tuning method to suppress subsequent commutation failure

电力工程技术
If a subsequent commutation failure occurs in the line commutated converter-based high voltage direct current (LCC-HVDC) transmission system, it will have a seriously negative impact on the safe and stable operation of the AC-DC hybrid power grid. Aiming

Study on lightning overvoltage and commutation failure in UHV AC/DC hybrid system

The Journal of Engineering, 2019
Due to the high UHV AC/DC transmission line tower, the working voltage amplitude on the wire is large, causing lightning accidents. The paper first analyses the impact of lightning strike point on lightning overvoltage of 1000 kV UHV transformer ...

Effect of commutation failure on the distance protection and the countermeasures

IET Generation, Transmission & Distribution, 2015
Commutation failure (CF) may be caused by AC fault in AC/DC interconnected system, and it will affect the performance of distance protection. The transient characteristic of equivalent current of power‐frequency of the dc–ac inverter is first analysed by introducing the concept of quadrant.

Teaming Up for Sustainability: Understanding Different Types, Projects, and Enablers of Employee Sustainability Teams

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Employee sustainability teams—groups collaborating continuously and voluntarily on sustainability initiatives—can serve as a bottom‐up driver for organizational change. Despite their potential, however, their role and contributions are underexplored. To fill this gap, our multi‐case study examines 59 projects by 13 teams across three companies

Stability Bounds for the Generalized Kadanoff‐Baym Ansatz in the Holstein Dimer

Contributions to Plasma Physics, EarlyView.
ABSTRACT Predicting real‐time dynamics in correlated systems is demanding: exact two‐time Green's function methods are accurate but often too costly, while the Generalized Kadanoff‐Baym Ansatz (GKBA) offers time‐linear propagation at the risk of uncontrolled behavior. We examine when and why GKBA fails in a minimal yet informative setting, the Holstein

A New Shunt Capacitor-Commutated Converter for Reducing Commutation Failure Probability of HVDC Transmission and Converter Transformer Noise

IEEE Access
The HVDC transmission system with a line-commutated converter is prone to commutation failure when connected to a weak AC grid and has disadvantages such as a large footprint of AC filters and high noise from the converter transformer.
