Design and Modelling of Bifurcated Winding Induction Generator (BWIG) using 3D EXPERIENCE software of Dassault Systems 

This work is carried out in 3DEXPERIENCE platform , there is a software tool named Dymola Behavior Modeling, which follows modelica language to analyse applications related to different engineering domains. The Aim was to create BWIG model and simulation is carried for different characteristics under the Dymola Behavior Modeling software tool.

Objective

• To Develop Simulation model for the Bifurcated Winding Induction Generator.

• To get constant Frequency of 50 Hz output voltage and to observe machine performance and Characteristic.

  1. Speed current Characteristics 

  2. For Different Excitation Voltages.

  3. For Different Prime Mover Speed.

The below Figure shows the CATIA Dymola model with kinetic load profile were toque Design and Modelling of BIFURCATED WINDING INDUCTION GENERATOR using 3DEXPERIENCE software of Dassault Systemes varies as square of speed. Where Asynchronous Induction machine (AMIC) is Excited with 3 phase voltage in figure it is shown that star connection to the three phase supply and it has current sensor, voltage sensor and power sensor to calculate the parameter which is interested. The rotor is provided with inertia and speed sensor and a torque source to show it as a load negative torque value is given. Speed sensor reads the speed of the rotor. 

SIMULATION AND RESULTS 

PROJECT OUTCOMES

Simulation of BWIG to get constant Frequency (50 Hz) output voltages and to observe machine performances and characteristics. – Simulation carried out and output voltage of 50 Hz is obtained. 

1. For Field Current.- characteristic curve excitation current versus speed is plotted. 

2. Speed of Prime Mover – The output voltage for different prime mover speed is observed and the frequency of 50 hz is maintained for different speed and also Amplitude of output is observed constant for different value of speed. 

3. For Different excitation voltage.-The output voltage for different input voltages is simulated and output voltage of 50 hertz is achieved. The output voltage (Amplitude) was observed proportional to input voltage.
