摘要
针对现代电网系统结构复杂、规模巨大、极易使故障发生扩散的现状,分析电力系统连锁故障的诱因、发生机理和发展特性,提出一种基于复杂网络重要节点的过负荷脆弱性评估方法,通过实验室仿真验证了该方法的可行性,结果表明该方法可以相对直接的对连锁故障的发生进行预测,在一定程度上估算故障后果,并提出比较可靠的处理意见。
For modern grid system structure complex, and scale huge, and be easy to make fault occurred diffusion, this paper validates the method feasibility through laboratory simulation, and this method can forecasting the cascading fault relatively de reedy, estimates fault consequences to a certain degree, proposes reliable processing views.
