Least Square Estimation Method: As we are going to seen that, the problem of power system state estimation is a special case of the more general problem of estimation of…
Factors Affecting Transient Stability: Factors Affecting Transient Stability - The two-machine system can be equivalently reduced to a single machine connected to infinite bus bar. The qualitative conclusions regarding system…
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…
Double Line to Ground Fault (LLG): Figure 11.9 shows a Double Line to Ground Fault at F in a power system. The fault may in general have an impedance Zf…
Line to Line Fault (LL): Figure 11.7 shows a Line to Line Fault at F in a power system on phases b and c through a fault impedance Zf. The phases…
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…
Symmetrical Component Analysis of Unsymmetrical Faults: Symmetrical Component Analysis of Unsymmetrical Faults - Consider a general power network shown in Fig. 11.1. It is assumed that a shunt type fault…
Waveform of a Short Circuit Current on Transmission Line: Let us consider the Short Circuit Current on Transmission Line. Certain simplifying assumptions are made at this stage. The line is…
