Inductance profile has an important bearing on the performance of a Switched Reluctance Motor (SRM) This paper presents the results of a frequency respolse method to estimate the inductance profde of SRMs. Stator winding is energized by a variable voltage variable Frequency supply. An approximate equivalent circuit incorporating stator resistance, winding(More)
—This paper deals with the performance analysis of static compensator (STATCOM) based voltage regulator for self-excited induction generators (SEIGs) supplying non-linear loads. In practice, a number of loads are non-linear in nature and therefore they inject harmonics in the generating systems. The SEIG being a weak isolated system, its performance is very(More)
Power Generation from Renewable energy sources like wind, solar, geothermal, biomass, and hydro is predominant now days and among the renewable energy sources, small hydro and wind energy have the ability to complement each other. For Power generation by small or micro hydro as well as wind systems, the use of squirrel-cage induction generators (SCIGs) is(More)
This paper deals with a control algorithm for two parallel-operated doubly fed induction generators (DFIGs) driven by wind turbines in a three-phase four-wire autonomous system feeding local loads.

This paper deals with an integrated voltage and frequency controller (IVFC) for a self excited induction generator (SEIG) in a standalone micro hydro system. The proposed IVFC is used to control the terminal voltage as well as frequency of SEIG system. This IVFC consists of a 3-phase 3-leg current controlled voltage source converter (CC-VSC) and its control(More)
This paper is aimed at design and implementation of a modified electronic load controller (MELC) for constant frequency operation with voltage regulation of a two winding single-phase self-excited induction generator (SEIG) applicable for renewable energy applications specifically for off-grid power generation using a small-size hydro energy. The system(More)
This paper presents a user friendly software based solution for complete evaluation of steady-state behavior of SEIG under different operating conditions. The mathematical modeling of the machine is carried out and then simulated in MATLAB's Graphical User Interface (GUI) environment and active windows are created with these models.
