Abstract
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 …
