The Study on Philosophy of Measurement of Phasor in Power System

Li Xinran (Changsha Univ.of Electr.Power Changsha 410077)(Huabei Univ.of Electr.Power Beijing 102206)  
The philosophy of measurement of current phasor and voltage phasor in electric power system is studied based on DET theory.The effects of sampling frequency and aperi- odic component on accuracy of measurement results are compared.Simulating computation shows that the error of phasor amplitude or phasor argument will be less than 2% if proper pre—filter is applied.
