摘要(Abstract)：

根据《电力系统安全稳定导则》,从短路电流、静态安全性、暂态稳定性、动态稳定性等方面,校核了特高压同步电网方案的安全稳定性;根据《电力安全事故应急处置和调查处理条例》要求,校核了可能发生的自然灾害导致的电网严重故障下,特高压同步电网的承受能力及可采取的措施;根据第3道防线的设置原则和要求,分析了由低频减载、低压减载和解列控制构成的第3道防线在特高压同步电网的适应性。结果表明,特高压同步电网安全性满足《电力系统安全稳定导则》的要求,承受严重故障能力强,第3道防线可有效控制事故范围,避免出现大停电;采用基于广域同步量测信息的自适应解列、交直流协调控制等技术可以进一步提高系统的安全性。
