Induction motor is the most popular load in the industry, it is very important to study about the effects of voltage quality on induction motor performance. One of the most important voltage quality problems in power system is voltage unbalance. This paper evaluates and compares two methods including finite element method (FEM) and equivalent electrical circuit simulation for investigation ...

The most essential infrastructure of today’s modern civilization is the energy system. A new revolution ongoing worldwide in understanding affordability, reliability, and sustainability supply. One major challenges opportunities considered this integration varying dynamics renewable production environmental conditions between different sources are reasons for challenge. Wind solar energies best...

The recent past has witnessed a rising demand of electric energy. The near future will see depletion in the fossil fuels like the coal, diesel and the petrol reserves, so emphasis has to be given on the renewable energy sources. Wind Energy has proven to be a significant option for the present energy resources. There is need for more analysis in the Wind energy sector so that it can be more rel...

In order to broaden the limited utilization range of wind power and improve the charging and discharging control performance of the storage battery in traditional small wind power generation systems, a wind power system based on a vertical-axis off-grid induction generator is proposed in this paper. The induction generator not only can run in a wide wind speed range but can also assist the vert...

Multiple coupled circuit modeling of squirrel-cage induction motors, or winding function approach is the most detailed and complete analytical model used to analyze the performance of the faulty induction motors. This paper extends the above-mentioned model to a saturable model including variable degrees of the saturation effects using an appropriate air gap function and novel techniques for lo...

In this paper, DQ-modeling approach for Transient State analysis in the time domain of the threephase self-excited induction generator (SEIG) with squirrel cage rotor is presented along with its operating performance evaluations. The three-phase SEIG is driven by a variable-speed prime mover (VSPM) such as a wind turbine for the clean alternative renewable energy in rural areas. Here the prime ...

The non conventional sources are important now days because the raw material required is less and power demand is more to compensate with the increasing demand of power, so renewable energy sources are important Micro grid which resembles a power system consisting of several distributed generators connected together and this micro grid operates in connecting mode which is connected to the main ...
