摘要：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 accompanied by very high values of the start-up current, associated with important voltage drops on supply cables, which results in the extension of the motor starting time. The present paper shows an efficient method of driving the cooling water pumps by the supply of electric driving motors with variable frequency.
