| Abstract: | Virtual Instrument technology is applied in phase difference measurement for electric power system, in this paper correlation analysis are discussed. Correlation analysis is improved, and a sort of new method is brought forward on double correlation analysis. By simulate experiment, the measuring error is analyzed.Compared with traditional way, the algorithm for phase difference measurement based on LabWindows/CVI has the advantages of exactitude, speedy and anti jamming. In virtue of computer communications network, the phase difference real time measurement is realized. |
