Automatic voltage regulation of synchronous generator with pole assignment self-tuning regulator

Extended SMC for a stand-alone wound rotor synchronous generator

“…Notice that (19) also implies Figure 2, plot the region where the inequality (19) fulfills. This numerical analysis corresponds to the experimental case presented in Section V (see the WRSG parameters in Table II) and shows that for a given load value, there exists two invariant regions (one of each containing one equilibrium point)…”

“…The stator voltage regulation has been mainly studied using linear techniques. From classical approaches in [16] and [17] or a PID design [18], to a more sophisticated methods as pole assignment self tuning technique [19] or, more recently, using H ∞ algorithms [20] or Robust controllers [21]. Linear control methodology is usually insufficient for inherent nonlinear high-order multivariable plants such as AC machines where parameter changes caused by winding temperature variation, converter switching effect and saturation are well recognized and infrequently accounted for.…”

Increase Productivity and Absorption of Reactive Power for Power Station with Using Static Reactive Power Compensator

“…In [2] algorithm based on geometric location for poles (Pole-Placement) and minimal changes (Minimum-Variance) was used for reducing the estimation time constant which was confirmed experimentally. But again the time constant is not decreased more because of estimation procedure.…”

Reactive Power Control of an Alternator with Static Excitation System Connected to a Network

“…Most researchers on modeling and simulation of generating systems found in the literature [1][2][3][4][5] did not use detailed models for the generating units with their detailed excitation system. Moreover researchers who implemented PI and PID controller for AVR in their models ignored a detailed procedure for determining controller parameters.…”
