Symmetrical Component Transformation: Symmetrical Component Transformation is given by a set of three balanced voltages (phasors) Va,Vb,Vc is characterized by equal magnitudes and interphase differences of 120°. The set is…
Selection of Circuit Breaker: There are two types of Selection of Circuit Breaker ratings which require the computation of SC current are: (i) rated momentary current and (ii) rated symmetrical…
Short Circuit of a Synchronous Machine on No Load: Short Circuit of a Synchronous Machine on No Load - Under steady state short circuit conditions, the armature reaction of a…
Introduction to Symmetrical Fault in Power System: Introduction to Symmetrical Fault in Power System devoted to abnormal system behavior under conditions of symmetrical short circuit (symmetrical three-phase fault). Such conditions…
Derivation of Transmission Loss Formula: An accurate method of obtaining a general derivation of transmission loss formula has been given by Kron. This, however, is quite complicated. The aim of…
Load Flow Analysis in Power System: Load Flow Analysis in Power System describes, the complex power injected by the source into the ith bus of a power system is where…
Power Flow through Transmission Line: So far the transmission line performance equation was presented in the form of voltage and current relationships between sending-and receiving-ends. Since loads are more often…
Long Transmission Line: For lines over 250 km, the fact that the parameters of a line are not lumped but distributed uniformly throughout its length, must be considered. Figure 5.10…
