Research on Monitoring Technology and Algorithm of Broadband Measurement Device in Substation
Due to the grid connection of numerous power electronic devices,the power system frequently vibrates and gradually develops towards broadband vibration,which leads to chaotic and unpredictable broadband dynamic performance of the system.At present,the mechanism of broadband stability in power systems is not clear,and the correctness of simulation analysis models is also insufficient,resulting in offline analysis and control methods based on numerical simulation difficult to adapt to the complexity of broadband dynamic characteristics.The article studies the monitoring methods of broadband measurement devices in substations,and uses window function algorithms to measure and monitor broadband signals in real-time,providing a new technical solution for real-time monitoring of broadband oscillations in substations.
