摘要
Abstract
In order to solve the current technology problems of harmonics detection and estimation in the field of power system, this paper attempts to combine the approximate entropy measurement and the chaotic oscillator firstly .Based on the theoretical analysis and the simulation research , this paper proved that the output approximate entropy of the a-daptive-step-length intermittent chaotic oscillator is just relevant to the frequency of the signals to be detected .For the approximate entropy had oblivious differences under different conditions , this paper proposed the intermittent chaotic oscillator with the approximate entropy measurement , and described the applicability of this new method to the har-monics detection .Besides , this paper improved a synchronization estimation method of the amplitude and phase of sine signals based on Duffing system , which made the method complexity lower and the real-time performance better , and the high accuracy estimation of amplitude and phase synchronization was realized .关键词
