摘要：
According to 'Guide on Security and Stability for Power System', security and stability of UHV synchronized power grids were evaluated in following aspects: short-circuit current, static security, transient and dynamic stabilities. Based on requirements of 'Emergency disposal, investigation and settlement regulations of electrical safety incidents', fault tolerance ability of UHV power grids and available measures were verified under serious failure conditions, probably caused by natural disasters. According to setting principles and requirements, adaptability of the third defense line was analyzed including under-frequency load shedding, under-voltage load shedding and splitting. Results indicated that security performance of UHV synchronized power grids can meet demands of 'Guide on Security and Stability for Power System' and has strong capability of withstanding serious failure. The third defense line can effectively control failurescope and avoid blackouts. Self-adaptive splitting technique based on wide area synchronous measurement information, together with AC-DC coordinated control technique, can further improve power gridsecurity performance. © 2016, Power System Technology Press.
