Abstract In RMS value and active power measurement of AC, The spectral leakage of harmonics on zero frequency is the main source of errors of measurement when sampling is not synchronized. Spectral leakage cancellation algorithm(SLCA) can reduce such measurement errors. theoretical analysis and numerical simulation are conducted in this paper and the results show that the algorithm can markedly improve the measurement accuracy.
