Jakość i efektywność energetyczna układów napędowych dużej mocy przy zasilaniu z rezerwowych zródeł energii

Paper presents feasibility of the high power generation sets as stand - by power sources in power stations effected by black - out. Using conventional system, in which the starting motor, driving main pump, is supplied directly from the generator, we need enormous installed power in stand - by generation units. However, using power electronic converter, acting as variable frequency source we proposed fully controlled start with full moment without current overload and the generator supply power is equal only 60% of the rated power of the motor pump.
