| Abstract: | A multi-point real-time power quality monitoring system is designed for regional power grid,which integrates the process field bus and the real-time operating system on virtual instrument platform to handle the massive grid data and acquire the high-frequency signal change.The optimal measuring point algorithm is proposed,which applies the covering matrix to quickly locate the fault point for reducing the amount of measuring points and improving the monitoring efficiency to more than 10 K.The intelligent po... |
