摘要

直流中断技术是柔性直流输电工程的瓶颈问题。基于人工零流的高压直流真空断路器是解决这一问题的一种可行有效的方法。在该断路器中，换相支路的参数对断路器的开断过程有着至关重要的影响。本文对基于人工零流的直流输电中断过程进行了建模和仿真。研究了换相支路参数对中断过程的影响。对不同工况下的仿真结果进行了分析。在此基础上，提出了合理的换相支路参数，以提高断路器的分断能力。

Simulation and analysis of a HVDC vacuum circuit breaker based on artificial current zero

HVDC interruption technique is the bottleneck problem of flexible HVDC project. The HVDC vacuum circuit breaker based on artificial current zero is a feasible and effective method to solve this problem. In this circuit breaker, the parameters of the commutation branch have a vital influence for the breaking process. In this paper, the interruption process for HVDC based on artificial current zero is modeled and simulated. The influence of commutation branch parameters on interruption process is studied. The simulation results under different conditions are analyzed. Based on the analysis, this paper puts forward the reasonable parameters of the commutation branch, which could improve the breaking ability of the circuit breaker.
