1. INTELLIGENT ONLINE MEASUREMENT AND
MANAGEMENT OF ENERGY METER DATA THROUGH
ADVANCED WIRELESS NETWORK
In this paper with the help of an energy chip, an improved energy metering solution is
developed, where automating the progression of measurement through digital wireless
communication technique is adopted to get the above benefits along with smooth control. The
developed energy meter calculates the total average active power mainly for residential
consumers. The hardware circuit accepts single phase voltage and currents as its inputs and
provides the output in the form of logic data proportional to the average real power. This data is
fed to a remote computer server through the wireless ZigBee network that represents the concept
of distant wireless metering, practically involving no manpower.
Existing System:
In this existing system, it needs a manual power to monitor and measure the meter
reading in the power meter. And also if any fault current flow i.e. changes of current flow
between phase and neutral are not monitored. So it is very difficult to detect those types of
situation in the industries.
Proposed System:
In this system we are able to monitor and measure the meter reading from the remote
place. Here we are using Zigbee wireless technology, current sensor which is all interfaced with
the microcontroller. The Load is connected with the power supply using Energy meter, the meter
measures the values and then the values are fed to microcontroller, then the microcontroller
transfer the meter value to internet using zigbee wireless technology. In other end PC receives
meter value using wireless and uploaded to internet using V.NET application. EB department
can see the customer EB value through internet itself. The PIC microcontroller senses the
current value of phase and neutral and compare with that value for fault identification. If fault
occurs the microcontroller invokes the alarm indication.
