Optimisation of the Start-up and Operation Regimes of Cooling Water Pumps of a High-Power Hydro Generator

It is necessary to make sure that the operation of cooling installations of hydro generators could be made in conditions of enhanced security so that the probability of defects occurrence during their exploitation be practically null. The asynchronous regime of direct network start up is accompa...
