Algorithm Research and Implementation of Power Quality Parameters Analysis.

Abstract: In recent years, with the extensive application of power electronics technology, power electronic devices such as non-linear loads is used more and more in power systems, which is inevitable that related current and voltage waveforms have a greater degree of distortion, thus affecting the power quality. It created a greater impact on power system security and the economy. Therefore, Researching on harmonic voltage and current the impact of power quality has a strong practical significance. In order to achieve the analysis of power quality parameters, you need to combine harmonic analysis algorithms and power quality parameter calculation algorithms to achieve the intended purpose. This paper presents Newton''s algorithm for harmonic analysis, combined with power parameter calculation algorithm, achieved the power quality analysis purposes. [Copyright &y& Elsevier]
