摘要： Das erfindungsgemäße Verfahren zur Bereitstellung von Regelleistung 7, insbesondere primärer Regelleistung 7, in ein Wechselspannungsnetz 5 stellt diese aus einem Kombinationskraftwerk 1 aus einem Batteriespeicher 2 und mindestens einem Kraftwerk 3 wie einem Gas- und Dampfturbinenkraftwerk zur Verfügung. Die Abgabe der Regelleistung 7 ist durch einen Frequenztrigger mit einer Triggerfrequenz 17 gesteuert. Liegt eine Abweichung der Frequenz des Wechselspannungsnetz 5 innerhalb eines durch die Triggerfrequenz 17 symmetrisch um die Sollfrequenz 19 aufgespannten Intervalls, erfolgt die Regelleistung 7 durch die Leistungsabgabe 11 des Batteriespeichers 2. Weicht die Frequenz in größerem Umfang von der Sollfrequenz 19 ab, so trägt auch die Leistungsabgabe 12 des Kraftwerks 3 zur Regelleistung 7 bei. Durch diese Strategie wird das Kraftwerk 3 seltener in Leistungsbereichen mit erhöhtem Verschleiß betrieben. Gleichzeitig erlaubt die Bereitstellung der Regelleistung 7 aus der Leistungsabgabe 11 des Batteriespeichers 2 eine schnellere Anpassung der abgegebenen Regelleistung 7 an die basierend auf der Frequenzdifferenz zur Sollfrequenz 19 notwendigen angefragten Regelleistung 6.

摘要： An electric power plant comprises at least one electric machine (105) operable as a generator when rotated by a piston engine (108). The electric power plant comprises a control system (101) for interrupting the fuel supply of the piston engine in response to a need to interrupt power supply from the electric machine, and for reactivating the fuel supply in response to a need to reactivate the power supply. The control system is configured to keep the electric machine connected to voltage when the fuel supply of the piston engine is interrupted so as to operate the electric machine as an electric motor for rotating the piston engine. As the electric machine and the piston engine are rotating when the power supply from the electric machine is interrupted, the reactivation of the power supply can be fast.

摘要： Methods and systems for load alignment assistance are provided. An alignment current may be provided with a partial power converter through an n-phase supply line to a synchronous alternating current (AC) motor during a startup of a synchronous AC grid. The synchronous AC motor may receive polyphase AC power through the n-phase supply line from the synchronous AC grid during the startup. The partial power converter may be powered by a power source isolated from the synchronous AC grid. The alignment current may be controlled such that the alignment current causes a rotor of the synchronous AC motor to align with a rotor of a generator that powers the synchronous AC grid.

摘要： A power generating system (1) has an offshore remote system (2-11) and an onshore local delivery system (15-20) adapted to be connected to an electric power grid (30). The remote system has at least one synchronous generator (4) driven by a prime mover (3), a remote bus (10) to which the synchronous generator is linked, and a controller (39-41). A frequency wild transmission system (15) links the remote system to the local delivery system. The remote system and the transmission system deliver power without AC-DC- AC conversion, and the local delivery system comprises a back-to-back converter (20) to perform AC-DC-AC conversion for grid code compliance. In one example there are at least two prime movers, a synchronous generator (4) coupled to each prime mover, and said synchronous generators (4) are connected to the remote bus (10) so that the remote bus provides a common connection point. The remote system controller is adapted to match voltage and frequency of power delivered from all of the synchronous generators to the remote power bus for remote frequency wild synchronisation of the synchronous generators.
