Eigenvalue factor analysis
WebAccording to the eigenvalue analysis, the sub/super-synchronous oscillation modes of the grid-connected inverter integrated into a weak grid are thoroughly analyzed with considering the PLL and control delay. ... According to the participation factor analysis, it is concluded that PLL is the most relevant element in this SSO, which is the ... WebThe dialog box Extraction… allows us to specify the extraction method and the cut-off value for the extraction. Generally, SPSS can extract as many factors as we have variables. In an exploratory analysis, the eigenvalue is calculated for each factor extracted and can be used to determine the number of factors to extract. A cutoff value of 1 is generally used …
