RESEARCH AND DEVELOPMENT OF THE HARMONICS DISTORTION MONITORING DEVICE BASED ON FAST FOURIER TRANSFORM METHOD AND REALTIME MONITORING WITH HIGH PERFORMANCE COMPUTER

Abstract

Nowaday, energy becomes a key factor in the growth of the economy and the demand energy is
increasing along with industrialization and modernization of the country. Therefore, power quality becomes
more and more important not only power supplyer but also electricity consumers. In recent years, harmonic
pollution in electrical exceeds standard and have a increase trend. This problem has a huge effect on power
grid as well as the operation of loads. Thereby, it leads to the requirement to continuously monitor the
harmonic distortion to ensure power quality. However, current harmonic distortion monitoring methods
usually has complex technicals and a lot of cost constraints. In this paper, research content will be provide a
method to fabricate real-time voltage and current harmonic distortion analyzer device base on fast fourier
trasform method and wireless connection technology with low cost and without changing current
constructions.
