| Abstract: | As an accessional function of intelligent circuit breaker, which is one of embedded system, harmonic analysis is discussed in this paper. An example of simulation is given and validates higher calculation accuracy, faster calculation rate and lower request for resources. The new algorithm is fit in with analyzing high order harmonics and is superior to the harmonic analysis algorithms in the same term. |
