Abstract
Предложена структура новой системы автоматического управления обратимыми гидроагрегатами ГАЭС, работающими с переменной частотой вращения, что дает
возможность повысить их КПД. Проведен сравнительный анализ переходных процессов полученных на математической модели и данных полученных в результате
пусконаладочных работ гидроагрегата Днестровской ГАЭС.
It was suggested the structure of new automatic control system for reversible hydropower supply unit with variable rotation speed for hydroelectric pumped storage power plant. This structure gives potentiality to increase their coefficient of efficiency under changes of water head. It has been done the comparative analysis of transients that were obtained using mathematical mode and derived data from testing and commissioning hydropower supply unit on hydroelectric pumped storage power plant «Dnestrovskaya» . Based on simile it was estimated the accuracy of mathematical modeling. This made possible to hold extensive researches of all working modes of hydroelectric pumped storage power plant. Based on received results it has been proposed the practical implementation of automatic control system.
