Abstract:

向家坝—上海及锦屏—苏南±800kV特高压直流输电工程融冰运行方式拓扑结构为并联换流器结构,控制策略采用并联多端直流输电(multi-terminaldirectcurrent,MTDC)系统的电流裕度控制策略。对特高压直流工程融冰运行方式调试过程中出现的稳态直流电流偏大、极II解锁过程中金属回线纵差保护跳闸(metallicreturnlongitudedifferentialprotection,MRLDP)及极I闭锁过程中极II融冰方式跳闸等问题进行了详细分析,提出了融冰运行方式下提高逆变侧换流变分接头档位、禁止MRLDP保护等建议的解决方案。通过EMTDC离线仿真和锦苏直流工程现场调试对解决方案进行了验证。验证结果表明了解决方案的有效性,可为其它特高压直流工程融冰运行方式控制保护系统设计提供参考。
