Abstract: | Results are reported of an experimental study undertaken to analyze parameter sensitivity of digital protective relaying algorithms and to develop a methodology for evaluating those algorithms. The study is based on computer simulations of relaying environments and the algorithms. Representative algorithms and test conditions were chosen based on a theoretical study of previously published algorithms. A study of algorithm sensitivity to various power-system conditions and algorithm parameters is presented, and the algorithms are evaluated using an adaptive criterion function developed in the study |
