Design and implementation of protection scheme for induction motor based on temperature sensation control for various faults

Project Title

Design and implementation of protection scheme for induction motor based on temperature sensation control for various faults

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

Statistics show that an annual downtime of 0.5-4 per cent is to be expected, of which 33 per cent of the motor breakdowns can be attributed to motor overloads. Insulation damage accounts for 20 per cent of all breakdowns while phase failure, bearing damage and ageing account for 14 per cent, 13 per cent and 10 per cent respectively.* [ Electric Fault Motor Protection Systems by Raju Chikkannavar, QuEST Global ]

So our project is based on to protect an induction motor from electrical faults such as overcurrent, overvoltage, under voltage, overloading, excessive heat and vibration. We will do mathematical modeling, simulation and then design and implement the system on hardware.

Project Objectives

Aim: Design and implement a system to protect an induction motor from various faults such as overcurrent, overvoltage, under voltage, overload, excessive heat, and vibrations.

Objectives:

• Mathematical modelling of various faults in three-phase induction motor.
• Modelling and simulation of overcurrent, overvoltage, undervoltage, overload, unbalancing and single phasing.
• Implementation on hardware for OV, UV, OC, Overloading, Temperature and Vibration.

Project Implementation Method

Our planning to carry out this project includes:

• Literature review
• Mathematical modelling
• Simulation of faults
• Implement on hardware.

The components we will use with estimated price are:

i.     Three Phase Induction Motor (3 KW)  

ii.    Over Current Relay                                

iii.   Over Load Relay                                    

iv.   Phase Sequence Relay                            

v.    Vibration Sensor Module                       

vi.   Temperature Sensor                                

vii.  Pic Microcontroller                                

viii. Circuit Breaker                                       

ix.   Contactor                                                

x.    Current Transformer (CT)                      

xi.   Potential Transformer (PT)

Milestones

1st Quarter of the year: Literature review, mathematical modelling.

2nd Quarter of the year: Simulation of some faults.

3rd Quarter of the year:  Simulation of remaining faults and Implementation on hardware, results analysis and thesis write-up for final submission.

Benefits of the Project

1) As per proposed protection Scheme, we want to conclude that the scheme will protect three phase Induction Motor from various electrical faults i-e under voltage, over voltage, over current, over load, unbalancing, vibration, and single phasing.

2) If we implement this project in industry, it can prevent the loss of millions.

3) This Protection Scheme increases the lifetime of the Induction Motor.

4) Protects the 3 Phase Induction Motor from electrical damage.
