V dannoy knige rassmotreny printsipy modelirovaniya sovremennykh ustroystv releynoy zashchity elektroenergeticheskikh sistem v interaktivnoy obolochke imitatsii dinamicheskikh modeley Simulink sistemy matematicheskogo modelirovaniya MATLAB. Privedeny opisaniya sushchestvuyushchikh i vnov' razrabotannykh imitatsionnykh blokov dlya sozdaniya modeley pervichnykh i vtorichnykh tsepey. Rassmotren protsess zamera parametrov silovoy tsepi v normal'nom i avariynom rezhimakh. Dayutsya svedeniya o raschetakh ustavok releynoy zashchity. Sozdany modeli osnovnykh vidov releynykh zashchit. Provedeno issledovanie sozdannykh modeley v dinamicheskom rezhime. Eta kniga budet polezna pri issledovanii sushchestvuyushchikh ustroystv releynykh zashchit i avtomatiki, a takzhe pri razrabotke i vnedrenii novykh algoritmov ustroystv releynoy zashchity elektroenergeticheskikh sistem.
