Conventional automatic reclosing " s shortcoming is that it acts blindly entirely before reclosing and cannot distinguish instantaneous fault from permanent fault 传统的单相自动重合闸的缺点是在重合闸之前,完全是盲目的动作,无法区分线路发生的是瞬时性故障还是永久性故障。
Automatic reclosing exits an optimal reclosing time , but the operation manner and wiring manner change in ( l frequently so that optimal reclosing time changes accordingly 自动重合闸存在一个最佳重合时刻,然而由于系统运行方式和接线方式经常变化,因此重合闸的最佳重合时刻也是时刻变化的。
The thesis systematically and deeply studied in faults identifying of automatic reclosing and on - line obtaining the optimal reclosing time of transient faults based on wavelet transform and artificial neural network 本文较深入系统的研究了单相自动重合闸的故障判别及其瞬时性故障最佳重合闸时刻的捕获问题。
The major creative idea of the thesis is that it draws wavelet neural network into automatic reclosing firstly . the choice of input eigenvalue contains all kinds of electric parameters more completely and more perfectly 本文的突破之处在于首次将小波神经网络技术应用于自动重合闸中,尤其是输入特征量的选择更完全的包含了各种电气量参数,较为完善。
