提出了一种考虑紧急控制保护装置及直流系统概率动作特性的连锁故障动态仿真模型，应用该模型对2010年华东电网实际系统进行了动态仿真。在不同的直流运行方式、直流控制参数、交直流互联方式、交直流传输容量分配条件下，计算了系统的停电功率一停电概率幂律曲线，分析了直流输电对系统自组织临界性的影响。结果表明，在某些系统中选取合适的直流输电模式可以减小连锁故障及大停电的发生概率。

A dynamic cascading failure model considering the probability characteristics of emergency control and protection device and DC system is proposed, with which dynamic simulation of the 2010 East China power grid is performed. Under conditions of different DC operation modes, DC control parameters, AC/DC interconnection modes, and AC/DC capacity distribution, the outage power-outage probability power law curves of the system are calculated, and the impact of the DC transmission On system self-organized criticality is analyzed. It can be seen from the results that in certain systems, the probability of cascading failure and blackout can be reduced by selecting a suitable DC transmission mode.
