Abstract
Aim A simple and useful evaluation method of the elect ric power and energy of sinusoidal alternating current is presented. Meth ods By using data acquisition systems and sine wave curve-fitting metho d. The parameters such as power and power factor are obtained. Results [ WT5BZ]Compared with other methods, the amplitude, frequency and phase of sine wa ve can be given at evaluating the parameters of power and energy. Conc lusion And all of the specifications can be traced to voltage, current a nd frequency standard. Besides curve-fitting technique, a special single-frequ ency-filter is proposed to reduce the uncertainty of evaluation. The source of errors is described, and finally some methods to reduce the uncertainty of evalu ation are discussed.关键词
