This paper proposes a steady state method as a solution to the problem of initializing the dynamic models of induction motors in transient stability studies. The results of the proposed method are compared to those obtained by two conventional initialization methods that are used in current production grade simulation programs, in a test power system that includes an industrial subsystem with a significant amount of induction motor loads. It is also shown in this paper that using a correct initialization method for these dynamic devices is important, because the choice of the method can modify the results of the dynamic time-domain simulation, and therefore the assessment of power system stability.

In this paper a novel control strategy for a real synchronous generator is presented. It is based on linear, diagonal, low order, minimum-phase, fixed, and stable controllers. The controller was obtained via individual channel design (ICD), a framework that allows analysis and synthesis of multivariable control systems by means of classical techniques based on the Bode and Nyquist plots. The generator is part of a one machine – infinite bus system. A linearised model around an operating point in a rotating coordinate frame is used. The theoretical principles behind this control strategy are summarised for completeness. The results using this novel control strategy are obtained throughout simulations in MATLAB®.
