| Summary: | Smart Meter (SM) is an intelligent device with additional functions which include
the ability to measure and record energy consumptions, and allows two-way
communication with the utility for automated monitoring, and accurate billing
management. Smart metering program has gained importance and started to
be implemented in most developed country including Malaysia. The obvious
problem in this SM is it uses single communication system as there was no
contingency plan in transferring the data when the signal strength was weak or
failure during data transfer process. In addition, single communication on the
smart meter has limiting the location suitability of the meter. Thus, in this thesis,
a new Smart Energy Meter (SEM) with adaptive data transfer algorithm is
designed to accommodate the problem. The prototype of SEM is constructed
based on the modern Smart Meter design and modified with additional control
devices and sensors, so that it can measure, record and transfer the data using
designated algorithm combining three types of communication system in one
device; Wi-Fi, GSM and RF. The idea of combining three types of wireless
communication is to ensure the data fully transferred to the data center
accurately and promptly. The prototype is constructed through software and
hardware development and has been programmed using Arduino IDE software.
An algorithm for selecting communication system is developed by comparing
Received Signal Strength Indicator (RSSI) of Wi-Fi and GSM with the priority
given to Wi-Fi, followed by GSM and RF. The prototype has been tested on a
laboratory scale for its functionality by measuring the electrical parameters using
heating elements as the load, and its ability in transferring data through three
communications and monitoring as well as communicating with the SEM from
DIS. Index test on the algorithm performance is carried out at different locations
and atmospheric for example in an indoor area of KEE 009 laboratory (normal
weather), the outdoor area of KEE 009 laboratory in normal weather, multi storey
building and during thunderstorm weather. In a conclusion, SEM prototype and
adaptive communication data transfer algorithm with a combination of the three
communication will be another method to solve a single communication problem of SM and suitable in residential location that offered the proposed
communication infrastructure. |
