摘要：

The paper describes a new variable-window algorithm suitable for microprocessor-based high-speed distance protection. It is designed to calculate the apparent impedance while the data window is increased to a desired size after fault occurrence. High-frequency and DC transient characteristics are extensively investigated. The results of real-time testing show the improved performance in both operating time and reach accuracy.
