Notations : u u et v v sont des fonctions ; n n est un nombre entier ; l l, a a et b b sont des réels. Typically, Pbase= 1 PU Vbase= 1 PU Let, Qbase= reactive power Sbase= apparent power The remainder of the values may be derived from the normal relationships S=IVP=ScosφQ=SsinφV=I⋅ZZ=R+jXIbase=SbaseVbaseZbase=VbaseIbase=V2baseSbaseYba… In three-phase circuits, some relationships are defined differently from those used in single-phase circuits. Specifically, for three-phase systems, Sbase=√3Vbase.IbaseSbase=3Vbase.Ibase … Skatīt vairāk Consider a three-phase transformer with a rating of 700 MVA and a secondary voltage of 145 kV. Determine Ibase, Zbase, and Ybase. There is no obligation to choose the transformer’s ratings as the base values, but it … Skatīt vairāk There are many advantages to use the per-unit system in power network engineering as such representation results in more correlated and meaningful data. Some of these advantages are highlighted as follows: 1. … Skatīt vairāk The single-line diagram of a three-phase system is shown in Fig. 1. Using the common base Sb= 50 MVA, draw the impedance … Skatīt vairāk
