Open Conductor Faults: An open conductor faults is in series with the line. Line currents and series voltages between broken ends of the conductors are required to be determined. Figure…
Single Line to Ground Fault: Figure 11.4 shows a Single Line to Ground Fault at F in a power system through a fault impedance Zf. The phases are so labelled…
Types of Unsymmetrical faults in Power System: There are two types of unsymmetrical faults in power system namely, Shunt Type Fault: Single Line to Ground Fault (LG) Line to Line Fault…
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…
ZBUS Formulation: ZBUS Formulation is given by By Inventing YBUS The sparsity of YBUS may be retained by using an efficient inversion technique and nodal impedance matrix can then be…
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…
Speed Governor Dead Band and its Effect on AGC: The effect of the Speed Governor Dead Band is that for a given position of the governor control valves, an increase/decrease…
