Zasady doboru układu napędowego z przemiennikiem częstotliwości średniego napięcia i silnikiem indukcyjnym klatkowym o znamionowych parametrach: mocy 3150kW, napięcia 6kv, częstotliwości 72,5Hz do pomp wody zasilającej

In this paper, the criteria for the selection elements of the drive system water supply pump are presented. Currently, drive system with fluid coupling is used, which make a base for creating a new type of drive systems. Considered drive systems consists of squirrel-cage motor medium volatge and medium voltage invertor. The selection was dependent on qualitative and quantitative criteria, which describe technical, operating and economic properties. There were described three types of drive systems with medium volatge invertor. Moreover, application of new drive system with fluid coupling VORECON was considered. Based on charactristics of selected pump and predicted working point, calculated power input of drive systems, energy efficiency and distortion factor of input current. Obtained results allowed to quantify of mentioned drive systems. Further evaluation could be made based on propertis of drive system not inclued in this study. Presented method of drive system selection could be useful in practice design.
