Performance Limits of Three-Phase Self-Excited Induction Generator (SEIG) as a Stand Alone DER

Abstract

-This paper present a unified method of steady state performance analysis and limits characteristics of an autonomous three-phase self-excited induction generator (SEIG) driven by a wind turbine under different types of loads and speeds. The proposed method is based on a new mathematical function to solve for the real and imaginary components of the complex equation of the mathematical model. Performances limits, regulation and characteristics of different configurations will be thoroughly examined and compared. The proposed system will be modeled and simulated and the performance limits characteristics will be compared with variable speed and variable capacity.

Analysis and study of two‐dimensional parameter bifurcation of wind power farms and composite loads

“…In Slimene and Khlifi, two‐parameter bifurcation analysis has been conducted on a typical power system model. The SNB curve and HB curve have been obtained in parameter space considering active and reactive load effect on voltage stability.…”

“…With respect to two-parameter bifurcation analysis of HB, based on continuation method, only tracking of two-dimensional bifurcation boundary in power systems has been reported. 45 In Slimene and Khlifi, 46 two-parameter bifurcation analysis has been conducted on a typical power system model. The SNB curve and HB curve have been obtained in parameter space considering active and reactive load effect on voltage stability.…”

“…Similar relation is valid for the reactive power. The values for the coefficient of the model for different load components are available in the previous studies …”

Voltage and frequency regulation for autonomous induction generators in small wind power plant

“…To avoid the similarity rate, the mathematical model of SEIG is developed by Slimene and Khlifi (2017).…”

“…*Induction machines with cage rotors in isolated regions are invariably used for generation of electricity from wind. Self-excited induction generators (SEIG) are reported to be suitable for small scale wind power plants (Slimene and Khlifi, 2017;García et al, 2018) because of their advantages such as low price, robustness, ease of maintenance, self-protection, easy maintainability, availability and capability to produce electrical power even at variable speed (Slimene et al, 2015a;Pathak et al, 2015;Joshi et al, 2006). These may be operated on/off grid-connected.…”
