摘    要:为揭示直流输电系统分层控制中极控制层定熄弧角控制环节对系统运行特性的影响,分析了熄弧角指令值的变化对直流输电系统稳态运行工况、无功特性和换相失败的影响,并基于CIGRE直流输电标准测试系统,运用电磁暂态仿真工具PSCAD/EMTDC对理论分析结果进行了仿真验证.结果表明,定熄弧角控制器能改善交直流输电系统运行的稳定性,维持系统无功平衡,保证逆变器关断裕度以阻止换相失败的发生.

关 键 词:直流输电  熄弧角  稳态特性  无功特性  换相失败

Abstract:In order to indicate the influence of constant extinct angle controller which is a part of polar control level of DC transmission system on operation characteristic of high-voltage direct current(HVDC),the influence of extinct angle order on DC system steady operation condition,reactive-power characteristic and the commutation failure is detailedly analyzed.The theoretical analysis result is proofed with PSCAD/EMTDC based on CIGRE benchmark mode.The result shows that constant arc extingnishing angle control...
Keywords:high-voltage direct current(HVDC)  arc extinguishing angle  steady-state characteristic  reactive-power characteristic  commutation failure
