Sensitivity Factor in Power System: A security analysis program is run in a load dispatch centre very quickly to help the operators. This can be attempted by carrying out an approximate analysis and using a…
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 economically such that power is…
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. The former gives the security…
Power System Static Security Levels: A formal System State Classification of power system static security levels was first suggested by DyLiacco and further clarified by Fink and Carlsen in order to define relevant EMS (Energy…
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 Introduction to Power System Analysis…
Recent Trends in Power System Stability: Recent Trends in Power System Stability in design of large alternators tend towards lower short circuit ratio (SCR = 1/Xd), which is achieved by reducing machine air gap with…
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 stability drawn from a two-machine…
Numerical Solution of Swing Equation: Numerical Solution of Swing Equation - In most practical systems, after machine lumping has been done, there are still more than two machines to be considered from the point of…
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 a simple Equal Area Criterion…
Transient Stability in Power System: Transient Stability in Power System - It has been shown already that the dynamics of a single synchronous machine connected to infinite bus bars is governed by the nonlinear differential…
