针对电网调度过程中,相关节点数据异常监测和防误不及时的问题,设计一个基于电网调度运行的智能防误系统。系统通过嵌入式技术,将精确字符集(BM)算法融入电网调度数据监测中,通过优化监测数据达到精确数据的目的;对于超过设定值的异常数据,利用支持向量机(SVM)—主成分分析(PCA)算法进行防误校核,实现电网调度智能防误。实验结果表明,该系统能通过故障线路电流出现明显的波动,更准确地诊断出故障元件;电网调度防误准确率稳定在96%左右,最高达97%,且变化趋势不大。

针对当前去重方法存在伪基和伪偏移量问题,导致去重效果不佳,提出了基于Merkle哈希树的电力扰动数据安全去重方法。使用收敛加密方法,有效解决数据加密和去重矛盾,应用Merkle哈希树得到电力扰动数据块指纹,以此标记待去重电力扰动数据。利用POW协议证明拥有权检测重复数据块。使用扰动状态似然代替对数似然,避免电力异常扰动状态在去重标识过程中重复,实现安全去重。由实验结果可知,该方法最大基提取为3000 B、最大偏移量为6000 B,均未超过实验设定阈值,说明所提方法去重效果较好。
