Abstract:
In this paper, state-space equations of synchronous machine based on various sets of currents (dqo, FB0, 120, αβ0 components) as state variables are derived. These equations are then modified according to boundary conditions corresponding to different operating states, and these modified statespace equations are solved with appropriate numerical methods. By comparingthis approach with the analytical method, it is shown that state-space analysis combined with suitable numerical methods has its outstanding advantages of simplicity, accuracy, and flexibility. This approach should be further developed. The specific problems analyzed, together with the frames of reference used and the mathematical problems encountered, are as follows: a. Three-Phase Short-Circuit and Self-Synchronization Transients—dq0 frame of reference; initial value problem of ordinary differential equations: b. Constant-Speed Asynchronous Operation—FB0 frame of reference; solution of complex linear algebrie equations; c. Forced Small Oscillation—dqo frame of reference; solution of complex linear algebric equations; d. Self-Oscillation and Self-Excitation—dqo frame of reference: eigenvalue problem of real matrix equations; e. Unsymmetrical Short-Circuit Transients—αβ0 frame of reference; initial value problem of ordinary differential equations: f. Sustained Unsymmetrical Short Circuits (Harmonic Analysis)—120 frame of reference; solution of complex linear algebric equations.
