Photovoltaic pumping using SVPWM Induction Motor Drive

Project Title

Photovoltaic pumping using SVPWM Induction Motor Drive

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

We are making an efficient industrial solar
water pumping system using Space Vector Pulse Width
Modulation (SVPWM) based Induction motor. A Push-Pull DC-DC converter is designed to boost the output voltage of the solar panel. The best features of the space vector PWM is the efficient and simple usage along with the reduction in total harmonic distortion (THD) with less switching loss and less computational calculations. Maximum Power point tracking algorithm is also used to extract maximum power at a given irradiance level.
 

Project Objectives

The main objectives of this project are:

• To Step up dc voltage of the PV array

• To design and simulate a three phase inverter that converts dc to ac power.

• Using space vector pulse width modulated inverter for speed control of Induction motor.

Project Implementation Method

First of all, we simulated our project on simulink matlab. After this we made our push pull converter for stepping up dc voltage we take from solar panel and made the voltage stable. We achieve maximum power using MPPT. Then we made our induction motor drive using Space Vector Pulse Width Modulation. After this, we integrated our induction motor drive with push pull converter. The three-phase voltage source inverter (VSI) in the drive receives the dc input supply from the output of the converter circuit and produces the required three phase voltage required to drive the induction motor which is used for different electric drive applications in industries.Then using our induction motor drive we controlled its speed.

Benefits of the Project

An efficient solar water pumping system fed by SVPWM based Induction motor.

The main advantage of using pushpull converter is that a
single panel will be enough to drive the motor via boosting the
output of solar panel by converter. Even if many solar panels are used to drive the load without a converter, there exist a problem of partial shading and output voltage at those instants are very low. In order to avoid all these problems a highly efficient pushpull converter is used.

Advantages of using  SVPWM techniques are

1) Better utilization of DC supply voltage,

2)Very Less harmonics

3) Higher modulation index,

SVPWM is simple in execution and is the most common technique to have better output.

 

Technical Details of Final Deliverable

Finally, Our project can be able to step up the dc voltages taken from the solar panel. We can also control the power using MPPT Algorithm and achieve max power. We are able to control the speed of our induction motor. We have reduced the total harmonic distortion. So, we have implemented an efficient solar water pumping using SVPWM induction Motor Drive.
