Research on The Cross-section Generation Technology of Power Data Based on Least Square Method

Accurate power data is used to analyze power grid operations by power advanced applications. In this paper, a data processing method is proposed to improve the accuracy of power data. This method achieves piecewise fitting of the collected data by used Least squares sine wave fitting algorithm with three parameters. A complete data curve is formed through above method, and then the cross-section data could be got from date curve. Finally, the accuracy of the electric cross-section data is proved by data analysis results.
