电网的不断互联,电力市场政策的逐步实施使得电网的动态行为更加复杂,电网运行越来越接近其稳定极限,一旦发生自然或者人为故障,如果不能及时有效地加以控制,将会破坏电网的稳定运行,甚至酿成大面积停电事故。为了保证电网稳定运行,防止大停电等恶性事故的发生,现代电网亟须有效的在线暂态稳定识别算法,能够快速识别出故障后存在的潜在危险,为紧急控制争取更多的时间。电力系统暂态稳定是研究电力系统在受到扰动后,
The continuous interconnection of power grids and the gradual implementation of power market policies make the dynamic behavior of the power grid more complicated and the power grid running more and more close to its stability limit. Once a natural or man-made fault occurs, it will undermine the stability of the power grid if it can not be controlled effectively in time Run, and even lead to a large blackout. In order to ensure the stable operation of the power grid and prevent the occurrence of serious blackouts such as blackouts, the modern grid needs an effective online transient stability identification algorithm, which can quickly identify the potential danger after the fault and gain more time for emergency control. Transient stability of power system is to study the power system after being disturbed,
