| Summary: | Electrical energy price has been increa
sing over the years. Due to this
reason,
home
users are getting more concern about the efficiency of the
electrical appliances
.
The solution
on
this problem is to create an energy usage monitoring system that can
monitor the energy used
by
electrical appliances
. The objective of this project is to
design and build a computer based energy monitoring system.
The system will be
consisting
of a compu
ter,
a data acquisition (DAQ)
module
, a voltage sensor and a
current sensor.
The LabVIEW graphical programming software by National Instrument
Inc. is used to design and build the computer interfacing software (virtual instrument
software)
.
Th
e system is a
ble to measure the source frequency, source voltage, current
drown by the monitored device, real power, apparent power, power factor, phase shift
between the voltage graph and the current graph (in both radiance and degree), kilo
-
Watt
-
hour reading, monito
red device operation time (elapsed time) and cost of operation
of the monitored device. The measured data
is
presented in both graphical and numerical
form. The system also has error detection capability (over voltage, voltage too low and
over current dete
ction) which will cut off the power supply when error is detected. The
database of the system is able to store both measurement data
and error report. This
system can be accessed remotely
by using the Windows Remote Desktop Connection
software. |
