Applied Research of Virtual Instrument in Measuring Three-Phase Unbalance Factor
摘要
Abstract
Three-phase unbalance factor is one of the important indicators in measure of power quality. With a wide application of nonlinear loads, power quality has been deteriorating much. To ensure the operation of electric power systems stable and safe, it is a very urgent need for real-time detection of Three-Phase unbalance factor. With the vir-tual instrument technology as a platform, the algorithms of positive-sequence component, negative-sequence compo-nent and zero-sequence component about voltage and current have been studied deeply in this paper, and three-phase unbalance factor can be further measured in power system. The example shows that three-phase unbalance factor de-tection system designed in this paper not only has high measuring accuracy but also possesses strong expandability, which will be used in measuring harmonic parameters of power quality.关键词
