Reducing reaction effect on mains with asynchronous generator switch=on - voltage jumps occurring at machine formerly with bridging of series resistances

摘要

The method uses a suitable selection of capacitors (CK) for the compensation of the reactive power of the generator and the selection of a suitable rpm, with which the series resistances (Rv) are bridged, with the switching carried out by contactors (K1,K2,K3). USE/ADVANTAGE - Suitable for all power plants with asynchronous generators e.g. water power, wind power, block heating and peak load power plants. Cheaper to operate, power factor controlled to give economic running. Shafts and couplings protected against surge loading.
