Empirical results showed that it is a promising way to design more powerful algorithms by combining different algorithms. It is interesting to investigate the relationship between the success ratio of a hybrid algorithm and those of basic algorithms on which the hybrid algorithm is based. In this paper, we analyze the relationship between the success ratios of two hybrid algorithms and those of basic...
This paper introduces a new strategy for power systems harmonics analysis based on N=L×10M-point DFTs. When the fundamental frequency of a power system signal is 50 Hz, a sampling frequency 2000 Hz is selected, N=L×10M-point DFTs can reduce spectral leakage and obtain high accuracy harmonic parameters. The simulation results in MATLAB show that the strategy are feasible, and comparing with the harmonic...
