Problem mit dem virtuellen Synchrongenerator zur Energiespeicherung
Dieser 3-phasige Synchrongenerator hat eine Maximalleistung von 5kW bei einer Nennspannung von 400V(230V)/50Hz und ist in Sternschaltung mit Nulleiter ausgeführt. Die integrierte elektronische Spannungsregelung sorgt für eine gute Spannungsstabilität auch bei hohen Blindstromanteilen.
How can virtual synchronous generators improve grid stability?
To increase the stability of such grids, virtual synchronous generators, which can be constructed by employing energy storage in conjunction with a power converter and an appropriate control mechanism, can provide virtual inertia. Synchronous generators provide a slower power balance as compared to VSG.
What is a virtual synchronous generator?
A virtual synchronous generator is another way to emulate inertia. It is established for a distibruted generator by using short- term energy storage with a power electronics converter combined with a control technique [ 11 ].
Do virtual synchronous generators provide more inertia?
To overcome these issues, the concept of virtual synchronous generators (VSG) is introduced, which aims to replicate some of the characteristics of the traditional synchronous generators using a converter control technique to supply more inertia virtually. This paper reviews the fundamentals, different topologies, and a detailed VSG structure.
Are virtual synchronous generators better than VSG?
Synchronous generators provide a slower power balance as compared to VSG. It has been proven that different VSG control algorithms have advantages and disadvantages depending on their applications. This paper reviews the critical issues of virtual synchronous generators. VSG’s core design structures are described.
What is a virtual synchronous generator-based control strategy for hybrid PV-diesel power system?
Conclusion In this paper, a new virtual synchronous generator-based control strategy has been proposed for a hybrid PV-Diesel power system in a stand-alone context. The control idea aims to synchronize the VSI and the DG without a PLL and with correction of the diesel generator rotor initial position.
