摘要
对电力系统实际运行过程中时常会发生的单一故障和由单一故障导致的连锁故障等演化过程中的动态特征进行研究,提取出能够反映电网动态特性的特征量,并采用蒙特卡罗方法对电网故障模式搜索方法进行了研究,建立了用于故障特征分析的样本集。同时采用相对变化率方法,在原始特征集中选取能够表征系统动态特性的特征量构建了动态响应特征集。研究结果为后继的大电网故障动态演化机理的研究奠定了基础。
The dynamic features of single fault and cascading failure caused by single fault during the operation of power system is studied ,the characteristics reflecting the dynamic features of power grid are extracted. Monte-Carlo method is used to study the way to search the failure mode of power grid. A sample is set for the analysis of fault feature based on the probability of different actual failure. Finally, the features that can reflect the dynamic characteristics of system are selected to construct the optimal feature set. The results can provide a guide for dynamic simulation evaluation and verification of architecture.
