Hardware Implementation of GSM based Smart Energy Meter

Project Area of Specialization

Electrical/Electronic Engineering

Project Summary

For the last few decades, Pakistan has witnessed a sharp growth in the demand for electrical energy in the residential, industrial, commercial, and agriculture sectors. The distribution network is operated by several DESCOs throughout the country. The utility companies mainly employ the manual metering system for billing purposes with many metering and billing staff. The aim of the project is to design and implement a smart energy meter for automatic recording of meter readings and communicate the information with utility companies and customers without any time delay and tempering risks. This system reduces the labor cost but also increases meter reading accuracy and saves a huge amount of time.

Project Objectives

The project aims the following objectives

1. Measuring energy consumption
2. Communication via GSM with a utility company and customer
3. Information/ Data recording of parameter values like power, energy, and date/time
4. Energy consumption over a specific period
5. Automatic detailed billing to consumers
6. Maintenance of data storage over a specific period 

Project Implementation Method

The above diagram elaborates the implementation model as it explains when the source and load are connected to the energy meter, the CT and PT measure current and voltage respectively. After measuring they send values to the microcontroller, (which in our case is Arduino) which after some calculations shows Parameters (like voltage, current, power, energy, and power factor) on L.C.D. G.S.M is used for communication and transmission of parameters. 

Benefits of the Project

The project focuses to ensure the following benefits

1. Accurate billing without any estimations
2. Timely billing without any environmental & manpower constraints
3. Soft recording and management of energy utilization by a consumer for a better budgeting
4. In the future, a possibility for the addition of more advanced features
5. A paperless environment means a green environment.
6. Less crowd in utility office saves time and human resource
