【摘要】：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。
[Abstract]:According to the security and stability for power system ", from the short-circuit current, static security and transient stability, dynamic stability, safety and stability check of UHV power grid project; according to the investigation and handling of the regulations on the requirements of emergency power grid safety accidents, serious check of possible faults caused by natural disasters. UHV power grid capacity and measures; according to the setting principles and requirements of the third line of defense, analysis by UFLS and UVLS, reconciliation column control third defense structure in UHV synchronous power grid adaptability. The results show that the UHV power grid safety to meet the" power system security stable guidelines >, under severe fault ability, the third line of defense can effectively control the range of accident, to avoid blackouts; using the adaptive measurement information based on wide area synchronized splitting The technology of AC and DC coordinated control can further improve the security of the system.
