摘要(Abstract)：

受华北—华中特高压交流通道静态稳定极限限制,天山—中州(天中)特高压直流和长治—南阳(长南)特高压交流通道输电能力存在耦合关系,成为制约该交直流混联电网稳定水平的关键因素。基于联络线功率波动理论,研究并量化了同步电网系统惯量、负荷特性、交流线路初始输送功率、直流落点近区开机方式等相关因素对华北—华中特高压交流通道潮流转移特性的影响;根据特高压交直流耦合关系,提出了一种交直流协调控制策略,以应对同类系统中受耦合关系制约的稳定问题。针对华北—华中电网实际数据,采用PSD-BPA电力系统仿真软件计算验证了该策略的有效性。

关键词(KeyWords)： 特高压交直流电网;潮流转移比;输电能力;系统稳定性;安全稳定控制措施
