Voltage Stability Analysis: The voltage stability analysis for a given system state involves examining following two aspects. Proximity to voltage instability: Distance to instability may be measured in terms of…
Network Observability and Pseudo Measurements: A minimum amount of data is necessary for State Estimation (SE) to be effective. A more analytical way of determining whether a given data is…
Contingency Analysis in Power System: In the past many widespread blackouts have occurred in interconnected power systems. Therefore, it is necessary to ensure that power systems should be operated most…
Power System Security Analysis: Power System Security Analysis can be broken down into two major functions that are carried out in an operations control centre: Security assessment, and Security control.…
Introduction to Power System Analysis: In earlier article we have been primarily concerned with the economical operation of a power system. An equally important factor in the operation of a…
Bus Impedance Matrix Method for Analysis of Unsymmetrical Shunt Faults: Bus Impedance Matrix Method of fault analysis, given for symmetrical faults  can be easily extended to the case of unsymmetrical…
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…
Sequence Impedance and Networks of Transformers: It is well known that almost all present day installations have three-phase transformers since they entail lower initial cost, have smaller space requireÂments and…
