摘要： A rotor (10) for a generator, especially for a turbogenerator, is assembled from a plurality of separate rotor elements (11, 12) which are arranged one behind the other in the rotor axis (18), wherein the rotor elements (11, 12) abut on connecting faces and are welded to one another, forming circular weld seams (17) which concentrically encompass in each case an annular central gap (37) with a predetermined gap width. In order to achieve a maximum magnetically active volume with mechanical stresses which are as low as possible, on the outer circumference of the gap (37) the gap merges into a widening cavity (38) which is adjacent to the weld seam (17).

摘要： A static exciter system (20) for the field winding (17) of a generator (16) which is connected to a grid system via a busbar (19) includes a first device (12, 18, 21) for production of a DC voltage, which is connected to the field winding (17) and together with the field winding (17) form an exciter circuit, as well as a second device (23; 29, C1, . . . , C3) for emission of electrical energy, which second device (23; 29, C1, . . . , C3) briefly feeds additional energy into the exciter circuit when required. An exciter system such as this results in the capability to briefly increase the excitation in a simple, functionally reliable and space-saving manner, by inserting a forward-biased diode (22) into the exciter circuit, and by the capability to connect the second device (23) to the diode (22), in the reverse-bias direction, in order to feed the energy into the exciter circuit.

摘要： A power station (10) includes a generator (13) which is driven by a turbine (11). The power station produces electrical power and outputs the electrical power to a network (17) via a generator switch (14). An electrical standby load (18) is also provided. When a network fault occurs, the generator is disconnected from the network by the generator switch and connected to the electrical standby load. The electrical standby load emulates the real load of the network that was present prior to the network fault, so that the voltage of the generator is stabilized at a constant phase difference or phase angle with respect to the voltage of the network that was present prior to the network fault. Alternatively, the value of the electrical standby load is adjusted during isolation of the generator from the network, to track the network while the generator is disconnected from the network and match the voltage phase angle of the generator to the network. Thus stability of the network is enhanced, because speed overshoots by the generator are avoided when the generator is disconnected from the network, and because the generator can be quickly reconnected to the network when the network fault is resolved after an extended time period, without performing a time consuming resynchronization process. For example, the generator can be reconnected to the network at a next current zero immediately following resolution of the network fault.
