Wireless power quality monitoring system

Wireless power quality monitoring system / Aida Amalina Ab. Jalil
Analisis pemantauan kualiti tenaga grid elektrik secara manual memerlukan masa dan usaha yang banyak, dan menyebabkan keputusan diagnosis yang salah. Oleh itu, sistem pemantauan kualiti kuasa tanpa wayar secara langsung diperkenalkan dengan menggunakan Arduino Yún. Masalah utama difokuskan pada pemantauan voltan yang berkurangan atau berlebihan. Objektif projek ini adalah mewujudkan sistem pengawasan kualiti tanpa wayar secara langsung dengan menggunakan Arduino. Mikrokontroler Arduino juga digunakan untuk menghasilkan sensor pemantauan kualiti kuasa. Projek ini terbahagi kepada dua bahagian; perkakasan dan perisian. Bahagiam perkakasan adalah mencipta fenomena voltan dalam pelbagai keadaan iaitu keadaan voltan berkurangan, berlebihan dan nominal. Papan Arduino Yún digunakan sebagai mikrokontroler untuk keseluruhan sistem. Selain itu, modul sensor voltan AC (ZMPT101B) digunakan untuk mengesan kehadiran voltan dalam sistem. Oleh itu, perisian Arduino IDE 1.8.8 digunakan untuk menukar isyarat digital menjadi isyarat analog melalui bahasa pengaturcaraan C. Aplikasi Ubidots juga akan digunakan sebagai medium tanpa wayar untuk menyimpan data dalam “Microsoft Excel” bertujuan untuk pemerhatian dan analisis. Simulasi sistem grid elektrik dibuat dengan menggunakan perisian “MATLAB/Simulink” untuk membandingkan keputusan eksperimen dengan keputusan teori. Keputusan eksperimen menunjukkan bahawa sistem berjaya dipantau secara wayarles dan data boleh diperolehi, dihantar, dan diproses dengan tepat. Kesimpulannya, sistem pemantauan yang dicadangkan menyumbang kelebihan yang signifikan melalui pelaksanaan pemasangan dan rangkaian mudah. _______________________________________________________________________________________________________ Manual analysis of an electrical grid for monitoring power quality may consume a lot of time and efforts, and sometimes lead to incorrect diagnosis. Therefore, a real-time wireless power quality monitoring system is implemented by using Arduino Yún. The major problems to deal with are voltage sag and swell. The objective of the project is to create real-time wireless power quality monitoring system by using Arduino. Also, it is to develop a power quality monitoring system by using Arduino microcontroller. This project is divided into two parts; hardware and software. Hardware part is developed to create the voltage phenomena under various conditions which are voltage sag, swell and nominal. Arduino Yún board is used as a microcontroller for the whole system. Other than that, AC voltage sensor module (ZMPT101B) is used to sense the presence of voltage in the system. Therefore, Arduino IDE 1.8.8 software is used to convert the digital signals into analog signals through C programming language. Ubidots application also will be used as a medium to store the data in Microsoft Excel wirelessly for observation and analysis purposed. In order to compare the experimental result with theoretical result, electrical grid system simulation is created by using MATLAB/Simulink software. Experimental results show that the system can successfully be monitored wirelessly and data can be acquired, transmitted, and processed accurately. In conclusion, proposed monitoring system contributes significant advantages through simple installation and networking implementation.
