Abstract
Mainly, this paper discusses about electrical power systems. Power systems are linked with power flow control, admittances matrix, eigenvalues, stability and contingency analysis. But here essentially it focuses on stability and contingency analysis. Under all possible operating conditions, new control techniques are presented in great demand. The small-signal stability model for 9-bus system and two-area four-machine 11-bus system is considered in this paper. All buses are modelled as classical model and six and eight state variables are used for the analysis. Individual machine rotor coordinates are transformed from reducing the network equations. The state variable formation came from linearizing network equations and machine differential equations. Generally, the small kind of fault is occurring at transmission area. To observe the system stability, find out the value of eigenvalues and eigenvectors. Finally, results show contingency analysis using IEEE 9-bus system and 11-bus four-machine power systems. The eigenvalues, participation matrix and sensitivity analysis value and all were produced based upon MATLAB Coding.
