摘　　要：本文就电网连锁故障的防治问题以相继开断为原则分别对相继开断预想事件的预测策略以及防治策略进行了初步探讨。针对电网连锁过载的识别,讨论了两种补偿法并对这两种方法的应用前景进行了讨论,认为追加电流源补偿法更适合于电网连锁过载的识别,然后进一步导出了追加电流源补偿法在保持网络准确参数条件下的补偿系数,并通过算例演示证明了该方法的有效性。Forecasting and preventing strategy for cascading outages is primarily discussed in this paper according to the rule of successive breaks in cascading outage process of power grid. Aiming at cascading overload of components of power grid, two methods with compensation are discussed in this paper, and the prospects of these methods are also dis- cussed. The current source compensating method is thought as a more appropriate method for identifying cascading overload, and the compensation coefficient in current source compensating method is provided, and an example of a system with 6 generators and 22 buses is provided to show validity of this method.
