Методи моделювання та програмні засоби для забезпечення надійності та живучості ОЕС України з використанням нових мікропроцесорних пристроїв керування режимами електроенергетичних систем

摘要

The object of an article is to present basic results of a scientific work according to plans of NAS of Ukraine. They are: methodics of the use of voltage phasors (WAM-systems) for the electric power systems (EPS) state estimation and for estimation of steady state stability level in the EPS sections; methodics and software for the automated calculations by the personal computers of short circuit currents in the nodes of complex electric network of u10023fPS and for determination of settings of EPS protection units in the microprocessor devices of REL521 the company u10023au10023cu10023c, which are used for 750…110 kV overhead lines; for medium-term forecasting of electro-consumption and electro-loading of UPS of Ukraine; for operative removal of the broken limits of electric parameters in power system elements.
