联于弱交流系统的HVDC换相失败研究
高压直流输电 弱交流系统 换相失败 逆变器
2009/9/25
高压直流输电(HVDC)系统逆变侧换流器处交流系统的强度直接影响HVDC系统的动态性能,换相失败是HVDC系统最常见的故障之一.通过分析逆变器换相失败的机理,归纳了联于弱交流系统的HVDC换相失败的各种影响因素,包括直流电流、换相电抗、换相电压、越前触发角,受端系统不对称等.利用Matlab的Simulink对交直流系统模型的动态特性及换相失败进行了仿真.
This paper presents a performance comparison (the focus of numerical simulation) of traditional simulation (TCS,TSE) with an optimal step time simulator (SOST) for large HVdc systems.In SOST, a Detail...
