USING THE RECURSIVE LEAST SQUARE ALGORITHM AND ADAPTIVESAMPLING TO REALIZE MICROCOMPUTER ELECTRICAL QUANTITY TRANSDUCER
Li Zhenran (Guangxi University Nanning)
In this paper,recursive least square algorithm was used to estimate the real part and imaginarg part of the complex amplitude of the fundamental voltage of the input signals that suf-fered noise pollution. The effective value of currents,voltages, active power and reactive power were calculated. the frequency and power factor were measured by using voltage phase anglechange. The accuracy of measurement was raised, the velocity of convergence was improved andcalculating quantity was decreased by adaptive sampling.
