摘要
在建立特高压直流输电准稳态模型的基础上,研究了向家坝-南汇±800 kV特高压直流接入对华东交流受端系统的稳定性可能产生的各种影响,包括特高压直流故障对交流系统稳定性的影响,基于调速器潮流的特高压直流故障后交流系统潮流转移特性,交直流交互作用机理分析以及对华东电网稳定性的影响,并基于短路容量动态等值法提出了交流系统故障诱发直流系统闭锁的关键性因素。
Based on the quasi steady-state model built for UHVDC transmission, the contributions of ＋ 800 kV Xiangjiaba-Nanhui UHVDC connection to the stability of East China Power Grid were studied, including the influence of UHVDC faults on the AC system stability, the power flow transfer characteristics of the AC system after UHVDC faults, and AC/DC interaction mechanism and related impacts on the stability of East China Power Grid. Moreover, the key factors in inducing DC system lockouts by AC system faults were proposed by using short-circuit capacity dynamic equivalence method.
