摘　　要：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。Aiming at the problem of abnormal monitoring and error prevention of relevant nodes in the process of power grid dispatching,an intelligent error prevention system based on power grid dispatching operation is designed.By using embedded technology,the system integrates the precise character set(BM)algorithm into the power grid dispatching data monitoring,and achieves the purpose of accurate data by optimizing the monitoring data.For the abnormal data exceeding the set value,the support vector machine(SVM)-principal component analysis(PCA)algorithm is used for error prevention check to realize intelligent error prevention in power grid scheduling.The experimental results show that the system can diagnose the fault element more accurately by the obvious fluctuation of the fault line current.The error-prevention accuracy of power grid dispatching is stable at about 96%and the highest is 97%,and the change trend is not large.
