Abstract (en)
[origin: WO9422200A2] The invention concerns a synchronizing device for parallel connection of a synchronous generator and an a.c. network with separate test connections for the voltage and the frequency of the generator and of the a.c. network, with control outputs for regulating the rotational speed of the generator drive. According to the invention, the preset feedback value for the generator frequency includes a defined slip at the start of balancing. Once the phase angle between supply voltage and generator voltage has gone below an appropriate value, null balance is applied to frequency. The advantage of the invention is that turbine regulation is seldom use, thus increasing the service life of the entire generator set.
