REAL TIME POWER MONITORING SYSTEM IN INDUSTRIAL MANAGEMENT (Hardware based) mini project

MAIN FIELD OF PROJECT:

The aim of this project is to design a practically realizable power monitoring system to observe variations in line voltage and line current and can also control the power factor.  This project also display and record the measured values on computer.

PROJECT OBJECTIVE:

The objectives of our project are :

Development of a Data-Acquisition Device* for measuring three phase physical parameters of AC Mains Voltage, AC Mains Current, Phase Difference, Power Factor, Real-Power, Reactive-Power, Apparent Power, Temperature, Battery Voltage (collectively regarded as data ).  It displays the corresponding values on an LCD display after measurement is done. 

PROJECT METHODOLOGY:

In hypothesis report project demonstration at every aspect will be help full for every user either professional or new. The basic tasks that will be performed in designing and presenting the project physically (circuitry) and in the soft form this will go through implementing signal conditioning circuitry, analog-to-digital converter (ADC), and computer bus and then presenting of final model with reports.  

SIMULATION  TOOL:

       Following Software and Simulation tools were used to aid my project and it’s Report, these simulation and software tools are used to design and develop project design and presentation.

  There are basically two codes written for the two different fronts of this project, 

Code  for hardware instrument.

Code for instrument interface with computer.

The code for instrument hardware is written in MikroC Pro for PIC 2011. The micro controller used is Microchip™ PIC18F452©.

The code for instrument interface with computer is developed, works on serial communication, and the application software is developed on NI LabVIEW 2011.

PROTEUS (Circuit designed).

Microsoft Office.
