摘要
针对三种常见高压输电线路拓扑结构,给出了基于广域量测系统(WAMS)的线路参数辨识方法,并结合实际算例展示了线路参数辨识在参数校核、事故反演分析方面的应用。最后,对于线路参数的辨识在电网中的其他应用进行了展望。
This paper proposes the transmission line parameters identification methods based on wide-area measurement system (WAMS) , for the three typical transmission line topologies. It shows the applications of transmission line identification in line parameter verification and post event analysis. Finally, the paper proposes other applications of transmission line parameter identification in power grid.
