Because of the special request of power measurement in the electrical power system, on the basis of the synchronous sampling, the paper analyses the reason for power errors and proposes to improve the precision of measurement of the electric power and energy by the adaptive sampling. Moreover the software self-learning compensation algorithm is given to compensate automatically the measuring accuracy influence as a result of the amplitude attenuation produced by the channel in the paper. The effect in the practical measurement application is evident and the precision is largely enhanced.
