“…In [24], a method based on space phasors has been introduced for dynamic analysis of transient symmetrical or asymmetrical faults in power systems. In this section, by developing the method described in [24], the dynamic analysis of a transient singleline-to-ground (SLG) fault in the IEEE 33-bus standard network including a HVDC-link is discussed. The method described here can easily be implemented to analyze other symmetrical and asymmetrical series or shunt faults.…”

“…These Equations guarantee the eliminating of time-varying inductances in the Park's voltage equations in unbalanced conditions. So, the conventional fullorder differential equations of the synchronous machine in the rotor reference frame could be used in unbalanced condition [24]. In the next section, the procedure of this method is presented.…”

This paper proposes a new adaptive sliding mode (ASM) decentralized excitation controller to improve the stability of multimachine power systems under different perturbations such as system' parametric and structural uncertainties. The stability of the closed-loop system is proved by Lyapunov stability theory. The proposed controller is evaluated through simulation on the standard IEEE 33-bus-bar power system which contains 6 synchronous machines and a HVDC-link. The simulation results indicate good robustness and satisfactory performance of the proposed controller. Moreover, in this paper, using the space-phasor based sequence networks method, a procedure for the dynamic analysis of modern power systems under the transient asymmetrical faults is presented. The method considers the complete dynamics of the synchronous machines and the HVDC-link and provides the possibility of taking into account the sequence networks dynamics.

“…Therefore, the numerical integration of DE by means of computational resources has become the main way to simulate SMrelated transient phenomena making use of a d-q axis model. Transient related to the electric system dynamic sta-bility [1,2], symmetrical and asymmetrical faults [3,4], load rejection [5], and asynchronous behaviors [6][7][8] have done large use of nonlinear SM models based on the d-q axis theory. In more recent time, the interest for the transient model of SMs has been awaken by the applications of embedded systems (ES) to the control of SM for industrial and traction applications [9][10][11][12][13].…”

The purpose of this paper is to carry out an alternative to the present transient models for field wound synchronous machines, which is able to take into account the nonlinearity of the magnetic materials as well as the cross-magnetization. After presenting the principal model structures according to the state variables, a model based on two lookup tables for the magnetizing flux linkages is introduced and built step by step. The resulting signal flowchart shows an algebraic loop within the model, where the main flux linkage rapidly converges to its instantaneous value by simple iteration. The proof of this convergence is given for both saturated and unsaturated machine. Even though the proposed model uses the total linkage flux as state variable, as many alternative models do, it does not require the inversion of the current to flux linkage function (i.e., of lookup tables). This can spare a heavy computational task, especially with very large lookup tables. In the proposed model, the computational effort in the worst case scenario is reduced to few iterations (<10). Finally, the nonlinear behavior of the model is verified in four different transient scenarios by comparing its outcomes with those of a linear model for the same test machine.
