摘　　要：输电线路的远距离送电使其频繁受到自然灾害的影响,极端自然灾害会造成电力系统大面积群发故障,严重影响电力系统的安全稳定运行,需要对自然灾害的防御方法进行研究。自然灾害的防御主要有提高一次系统设计标准以避免故障和通过安全稳定控制措施以减小停电损失两种方式。提高设计系统的标准需要较大的经济代价,且无法完全避免大面积输电线路故障。现有研究主要针对自然灾害的安全稳定控制方法进行研究,包括自然灾害防御所需的信息采集、自然灾害下电力系统风险评估以及应对自然灾害的电力系统安全稳定控制方法。为此,对现有自然灾害的安全稳定防御方法进行综述,并指出进一步研究方向,为后续的自然灾害的安全稳定防御方法研究提供参考。Long-distance transmission lines frequently suffer from natural disasters, which may result in large-scale cluster faults in power systems and further influence the security and stability of power system. Consequently, it is necessary to study the defense methods for natural disasters. The defense methods can be divided into two categories： improving the design standard for primary system to avoid faults, and implementing security and stability control methods to reduce the loss. However, improving the system design standard will increase large construction cost of transmission lines. In addition, the improvement of design standard cannot exhaustively eliminate faults of transmission lines. As a result, current research pay more attention on security and stability control methods for natural disasters from the following aspects： information collection for natural disaster defense, risk assessment of the power system under natural disasters, security and stability control methods for coping with natural disasters and so on. Therefore, this paper summarizes the security and stability control methods for natural disaster and points out some further research directions, which may provide a reference for future study.
