Abstract

The mathematical model of a controlled multimachine electric power system in matrix form is developed. The model is based on space state equations and on using the system nesting technology. By using the obtained mathematical model, it is possible to investigate small-signal stability of a controlled complex electric system through determining the eigenvalues of the system dynamics matrix. The method of decomposing the complex electric system initial model by means of semi-orthogonal matrix zero dividers is applied for shifting the system poles to the desired positions.
