More Information
Summary:In one embodiment, a computing device determines real and reactive power flows at a transformer at a given time, and computes, based on the real power and reactive power flow at the transformer, an amount of reactive power adjustment to produce a desired voltage differential across the transformer. The computing device may then adjust the reactive power flow from a secondary side of the transformer at substantially the given time based on the computed amount. L'invention concerne, dans un mode de réalisation, un dispositif informatique qui détermine des transits de puissance réelle et de puissance réactive au niveau d'un transformateur à un moment donné, et calcule, en fonction du transit de puissance réelle et de puissance réactive au niveau du transformateur, une quantité de réglage de puissance réactive afin de produire un différentiel de tension souhaité aux bornes du transformateur. Le dispositif informatique peut ensuite régler le transit de puissance réactive à partir d'un côté secondaire du transformateur quasiment au moment donné en fonction de la quantité calculée.
