According to the necessity for researching the optimization of enterprise energy-consuming based on model, the identification method for energy-consuming link in enterprise production process was researched. In view of the existing problems of Least Squares Support Vector Machine (LS-SVM), a modeling method based on nonparametric weighted feature extraction (NWFE) and LS-SVM was proposed. NWFE was...
An important step in economical operation analysis for transformers is the calculation of power loss curve. In order to find out the curve which best fits the actual conditions, we need to correct the nameplate ratings of the transformer. Taking the type test is the traditional method. But the result of this not-so-flexible method will become inaccurate with the lapse of time. Fitting the real-time...
Sine fitting is a fundamental task in many test and measurement systems. Total Least Squares (TLS) is an extension of the usual least squares method: it allows dealing also with uncertainties on the sensitivity matrix. A sine fitting algorithm based on TLS are employed to filter the sampled sequences of sine signals, eliminating ill effects on the measurement accuracy caused by noises (including the...
