RESEARCH OF THE REASONS FOR EXITING FROM THE ELECTRICAL EQUIPMENT OF PUMPING STATIONS OF HIGH POWER
The main technical parameters of the pumping station affecting the operation modes and reliability of the power supplv svstem are considered, technological processes of the irrigation pumping station are investigated, the analvsis of mechanical characteristics, causes of loss of svnchronism and failure of pumping units is made, a method for calculating the voltage dip is developed, an algorithm for calculating static stability is developed and the stabil ity margin of active power.
