“…For modelling a synchronous generator, the q-d axis model referred to the rotor reference frame is adopted, of which the electrical data are listed in Table II, where R s , X ls are the resistance and leakage reactance of the stator, respectively; R fd , X lfd are the resistance and leakage reactance of the field windings, respectively; X mq and X md are the magnetizing reactances referred to the q-axis and d-axis, respectively; and R kq , X lkq , R kd , X lkd are the resistances and leakage reactances referred to the q-axis and d-axis of damping windings, respectively. Based on the simplification process [17], the generator circuit model can be simplified to a single-axis circuit model shown in the right block of Fig. 2(a), where an ideal transformer interfaces the electrical and mechanical parts.…”

Wind turbine generators can be operated in various types of system configurations. Once the configurations change, the system oscillation mode shapes change accordingly. The modelling of the full system is necessary for studying this issue, yet it is quite hard. In this paper, a simple approach is developed to study the mode shapes of wind power systems without the necessity of adopting the complex full-system models.The key is that the q-d axis model of electric power system is transformed into the single-axis model, so that it could integrate with the equivalent circuit model of drive train mechanism. After analyzing some of the system configurations organized by the well-known MOD-2 wind turbine generator unit, the proposed approach is found to be effective for analyzing various oscillation modes such as the local torsional oscillations, as well as the inter-unit and inter-area oscillations.

We model the dynamics of solar thermal plants-the first model covering all processes between market demand through power output at millisecond resolution-for the purpose of control design. Our model integrates solar reflectors, power tower, salt tank, boiler, turbine, generator, piping, and pumps along with the flows of energy and information between them. We show how our detailed model permits control designs that can potentially enhance the life of the power tower, and thereby aid in reducing generation costs of solar power to a level competitive to current electricity price. Our modeling also opens up several problems of control and optimization of concentrated solar power (CSP) plants that can quickly bring the maturity of CSPs near that of traditional coal-fired plants and aid their integration with the other power sources. We show some of this potential via simulations. Index Terms-Concentrated solar power (CSP), controloriented model. 1063-6536
