系统联系阻抗实时最优估计及其在计算机保护中的应用

Real-time Estimation of System Interconnection Impedance and its Application in Computer Aided Relay Protection

本文提出了一种系统联系阻抗快速逼近公式,使保护能实时取得系统联系阻抗最优估计值,为研制自动适应运行方式变化的高性能计算机保护创造了条件。

The author has derived a fast approximation formula for computation of system interconnecting impedance which will make the real-time estimation of the optimalsystem impedance possible. This approach will enhace the development of high per-formance computer-aided relay protection that will automatically accomodate to the opera-tion mode change of large power network.
