| A new method of load online detection was presented according to the need ofpower system. The loads are sorted according to their index of capacitive,inductive,etc.The static character of each load was got according to the time-distributing. The powerload online emulation model and analysis software are designed based on the sampledata of PCI-9118DG. The epistatic software was designed for data management andanalyzing. The method for discrete status data was analyzed by wavelet transform toidentify the exact time of power load thrown-in and thrown-out;the identifying methodfor electric power loads status is deduced based on correlation coefficient. Wavelettransform is used to analyze the accurate localization of power load throw-in and out.The trueness and validity of the methods is verified based on the testing and analyzing.
