The identification of power apparatus parameters to be specified in transient models from frequency response tests is a well established practice. There has been, in addition, a significant effort in the development of fitting procedures that could derive the parameters from frequency response curves. This paper summarizes the present status of electrical parameter determination for synchronous machines...
In this Paper, we present a systematically method based on the transformer coupling effect to establish the d-and q-axes equivalent circuits, which can describe the transient behavior of the synchronous machine. The MATLAB/Simulink Power System Blockset tools (PSB) is used for the simulation of synchronous machines by their equivalent circuits. One used an empirical method, based on the comparison...
This paper deals with a combined analytical-numerical approach for the study of the steady-state and transient behaviour of three-phase transformers. This approach based on magnetic equivalent circuits, takes into account the nonlinear B-H curve. The nonlinear B-H curve is constituted by a set of measurement data and can be represented by a Fourier series or by a polynomial representation. For the...
