Principle Operation of Switching Power Converters: Controllable reactive power can be generated by dc to ac switching converters which are switched in synchronism with the line voltage with which the…
What is Shunt Compensation in Power System?: Shunt Compensation are connected in shunt at various system nodes (major substations) and sometimes at mid-point of lines. These serve the purposes of…
What is Series Compensation in Power System?: Series Compensation - A capacitor in series with a line gives control over the effective reactance between line ends. This effective reactance is…
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…
Equal Area Criterion in Power System: In a system where one machine is swinging with respect to an infinite bus, it is possible to study transient stability by means of…
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…
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…
Phasor Diagram of Synchronous Motor: The Phasor Diagram of Synchronous Motor is the most important element of a power system. It converts mechanical power into electrical form and feeds it…
