Abstract:
Smart Grid System plays an important role and is an effective means of data
collection and grid automation that allows substantial saving through the reduction of
meter reread, greater accuracy, allows frequent reading, improved billing and
customer service, more timely energy profiles and consumption trends updates, and
better deployment of human resource.
In this project, GSM technology is used to implement an AMR system by
means of PIC microcontroller that will read the power consumed by the customers and
send it to the power grid. Moreover a small Power grid is also implemented that will
be automatically supply the power according to the need of the customer by switching
the relays in order to avoid the loss of the extra power.
The GSM Energy Profiling System (GEPS) takes advantage of the available
GSM infrastructure’s nationwide coverage and the Short Messaging Service (SMS) to
transmit energy reading from the digital electric meters to the supplier (server) and
receive alerts at the consumer (User) end during the peak hours.
Dedicated Single phase meters are installed at the user end. Two meters were
implemented in this project. One that measures the power purely by the PIC
microcontroller and the second was implemented through the PIC and CS5463 SPI
interfacing. The microcontroller after measuring the energy generates a message that
contains the energy spent by the customer and this message is then transmitted to the
server over the GSM network via the transmission module (Serial GSM Modem). The
reception module is also a GSM modem connected to the server system which
receives the energy readings transmitted by the consumers and relays them to the
server system
If commercially employed, this is a comprehensive system which accurately
maintains and illustrates energy usage data via an efficient monitoring and profiling
system and extensive control by the supplier company.
