The development of the renewable energy and the need of medium- and high-voltage direct current circuit breakers are the keys in the development of medium- and high-voltage transmission systems. It can be used in high-voltage systems as cascaded interrupters. In this paper, the cascaded interrupters of gaseous circuit breakers are simulated using black box arc models. The influences of the models parameters on the arc interruption time are studied. MATLAB/Simulink program is employed to carry out this study. It is concluded that the simulated results by employing black box arc models achieve a success in multi-break HVDC gaseous circuit breakers simulation. Employing BBAM models has proved more flexibility to study the effect of different controlled and uncontrolled parameters on the multi-break HVDCGCB arcing time. That has proved more flexibility to study the effect of different controlled and uncontrolled parameters on the arcing time. From the investigated forty cases done to check the Mayr’s model validity in the HVDC CD simulation, it is found that the values of P and $$ \tau $$ τ which give acceptable outputs are at $$ \tau = 10^{ - 6} \;{\text{s}} $$ τ = 10 - 6 s , and P in range of 10 7 –10 11 W. The output of the case $$ \tau = 10^{ - 6} \;{\text{s}} $$ τ = 10 - 6 s , P = 10 10 W, which is introduced in the paper has proved that when $$ \tau $$ τ reached to 10 −7 s, the MOV current rises and drops and thereafter rises and gradually decreases. This may lead to CB failure; Com parameters influences on the interrupter performance are investigated and proved good simulation of the gaseous circuit breaker interrupter. The commutation parameters affecting the interrupter performance are investigated. Investigation of the change in the fault arc resistance and the fault location on the DC line on the arcing time is presented. Finally the impact of the changing of fault resistance value on arcing time and the damping resistance influence on the transient recovery voltage is also investigated. Additionally, the initial transient interruption and the metal oxide varistor voltages are analyzed.

基于黑匣子电弧模型的多断点高压直流气体断路器性能研究

可再生能源的发展和中高压直流断路器的需求是中高压输电系统发展的关键。它可以在高压系统中用作级联断路器。在本文中，气体断路器的级联断路器使用黑盒电弧模型进行模拟。研究了模型参数对电弧中断时间的影响。MATLAB/Simulink 程序被用来进行这项研究。得出的结论是，采用黑匣子电弧模型的模拟结果在多断点高压直流气体断路器模拟中取得了成功。事实证明，使用 BBAM 模型可以更灵活地研究不同受控和非受控参数对多断点 HVDCGCB 电弧时间的影响。事实证明，研究不同受控和非受控参数对燃弧时间的影响具有更大的灵活性。从在 HVDC CD 模拟中检查 Mayr 模型有效性的四十个案例中，发现给出可接受输出的 P 和 $$ \tau $$ τ 的值在 $$ \tau = 10^{ - 6 } \;{\text{s}} $$ τ = 10 - 6 s ，P 的范围为 10 7 –10 11 W。案例的输出 $$ \tau = 10^{ - 6} \;{ \text{s}} $$ τ = 10 - 6 s , P = 10 10 W ，文中介绍的证明当$$ \tau $$ τ达到10 -7 s时，MOV电流上升，下降，然后上升并逐渐下降。这可能会导致 CB 故障；研究了 Com 参数对断续器性能的影响，并证明了气体断路器断续器的良好模拟。研究了影响断续器性能的换向参数。研究了电弧时间上故障电弧电阻的变化和直流线路上的故障位置。最后还研究了故障电阻值变化对电弧时间的影响和阻尼电阻对瞬态恢复电压的影响。此外，还分析了初始瞬态中断和金属氧化物变阻器电压。
