Abstract
The paper describes a new variable-window algorithm suitable for micro processor-based high-speed distance protection. It is designed to calc ulate the apparent impedance while the data window is increased to a d esired size after fault occurrence. High-frequency and DC transient ch aracteristics are extensively investigated. The results of real-time t esting show the improved performance in both operating time and reach accuracy.
