The extensive usage of non-linear loads and electronic devices has resulted in increased vulnerability to the power quality (PQ) disturbances in the power system. Hence, the analysis of PQ disturbances becomes crucial to maintain the reliability of the distributed generation (DG). This paper presents the analysis of various disturbances like voltage swell, voltage sag, notch, flicker, spike, harmonics,...
This paper presents the transient performance analysis of self excited induction generator (SEIG) during both balanced and unbalanced faults using stationary frame d–q axis. Significance of fault detection and fault classification is also investigated in this study. Current signal of SEIG is extracted. Non stationary distorted current waveforms of SEIG during fault condition are considered as superimposition...
This paper proposes a fuzzy PI based voltage control scheme of the self-excited induction generator (SEIG) using static synchronous compensator (STATCOM) for feeding balanced and unbalanced load. The main aim of SEIG discussed in this paper is to regulate voltage under balanced and unbalanced load conditions. A three-phase insulated gate-bipolar-transistor based current controlled voltage source inverter...
In isolated and remote area researchers are motivated recently to generate power using wind. Self excited induction generator (SEIG) is selected as a good candidate to extract electric power from wind. In this paper transient performance of SEIG during short circuit fault has been studied. Though SEIG is capable to protect itself from faults, but it is also necessary convey the message to operator...
Self-excited induction generator (SEIG) is preferred in isolated and remote power generating systems. But the major problem associated with SEIG is change in voltage and frequency during loading condition. For the development of simple voltage and frequency controller it is essential to detect the load transient in less time using less hardware. In this paper Second Generation Wavelet Transform (SGWT)...
This paper derives the mathematical expression for the minimum excitation capacitance of self excited induction generator under different types of load and speed, and also studies the performance of a self-excited induction generator (SEIG) driven by a prime mover. Mathematical model of the isolated SEIG under balanced loading conditions in d-q stationary reference frame is developed to study the...
