摘要
提出了一种静止坐标下的序量分离与谐波检测方法.通过构建一种具有可选择指定频率与极性功能的一阶带通滤波器,实现了序量分离、同步化和谐波检测.分析了此滤波器的控制原理,并利用伯德图讨论其参数选择的原则,运用数学计算推导出其实现方法.在Matlab仿真软件中对该方法的典型应用进行了仿真,结果表明,该方法具有结构简便和性能良好的优点.
A new technique for sequence separation and harmonic detection is proposed. Thismethod realizes sequence separation, synchronization and harmonic detection by building a first-orderband-pass filter （FOBPF）which specifies frequency and polarity selection function. The controlprinciple of the FOBPF is analyzed and its regulation of parameter choice is discussed according to theBode Plot. Then, its implementation approach is deduced by utilizing mathematic calculation. Thetypical application of FOBPF are simulated in Matlab. The proposed technique shows good performancewith a simple structure in these applications ,it is verified by the simulation results.
